In March 2006, RHI signed a joint venture contract in China for the production of high quality magnesite raw materials. Sustainable investments in the strategic supply of top-quality magnesia for the Chinese plants and other RHI facilities in Europe and North America reduce RHI’s dependence on suppliers in the world market significantly. In addition to ensuring the continuously high quality of raw materials in the future, too, which is indispensable for the production of cutting-edge refractory products by RHI, the joint venture also achieves an important economic optimization.

HQM98 is produced by AODING, a joint venture of RHI (83%) and the Chinese partner Jinding (17%). AODING is located in Dashiqiao, Liaoning province, in northeastern China. Start-up of the JV was in April 2007; in June 2008 the first dead burned magnesia HQM98 left the shaft kiln. HQM98 is the short notation for high quality magnesia with an MgO content ≥ 98%. AODING processes raw magnesite from nearby Huaziyu mine; purification is achieved by froth flotation removing mainly silicate impurities. The concentrate is calcined in a multiple hearth furnace (MHF). With 18 hearth levels, it is the biggest MHF in the world. After briquetting the calcined magnesia is burned in a shaft kiln to dead burned magnesia or, alternatively, fed to the fusion plant. AODING´s annual capacity is 100.000 tonnes of MgO.

过去，镁铝尖晶石砖被认为是水泥工业无铬衬砌的领先技术。

已有的标准镁铝尖晶石火砖主要在氧化镁的类型以及氧化铝载体

的加入量和形态上有所区别(烧结和电熔的镁铝尖晶石，煅烧氧

化铝，刚玉等)。

现代水泥窑工况十分恶劣，(镁铝尖晶石砖)需要加入大量的氧化

铝于火砖内来满足耐火砖柔韧性的需求，氧化铝含量高成为镁铝

尖晶石砖的缺点。由于会形成低熔点的铝酸钙，因而在使用过程

中，该型火砖的热态强度，抗侵蚀性都会降低。

为了解决镁铝尖晶石砖的这个问题，奥镁研发机构在研发新品

时，关注于减少氧化铝的含量同时又改善新品的断裂力学性能。

在所有可能用于耐火材料的尖晶石矿物中，铁铝尖晶石和锰铝尖

晶石的效果最为显著。低的尖晶石加入量减少了氧化铝的引入，

故火砖的抗熟料液相和碱盐侵蚀能力都得到了显著地提高。铁铝

尖晶石还进一步地降低了火砖的透气性，减少了被有害成分渗

透的趋势。

Hercynite brickStandard mA-spinel brick

Wedge splitting test

In the past, magnesia-alumina-spinel bricks were considered as state-of-the-artfor chrome-free kiln linings in the cement industry.

Available standard MA-spinel bricks differ mainly in the type of magnesia and inthe amount and type of their alumina carrier (sintered and fused MA-spinel, calc.alumina, corundum, etc.).

Considering the severe conditions in modern cement kilns, the high amount of alumina in MA-spinel bricks required for flexibility has to be considered as a disadvantage. Due to the formation of low-melting calcium-aluminates the hot strength, corrosion resistance and erosion strength are reduced.

Because of this fact RHI’s research work has been focused on reducing thealumina content to a minimum with a simultaneous improvement of the fracture mechanics.

Of all possible members of the spinel group, hercynite and galaxite were found to be the most effective. Due to the very low amount of alumina required, the corrosion resistance to clinker melt and alkali salts is significantly increased.A further property is the low permeability that reduces the tendency toinfiltrate.

Despite the reduced alumina content, the tensile strength of magnesia-hercyniteand magnesia-galaxite bricks is kept at a much higher level compared to conventional premium grade MA-spinel bricks even at high temperatures.

Wedge splitting test: the specific feature of this testing method is the determination of fracture mechanics at high temperatures (1100 °C to 1250 °C) to determine flexibility.

尽管降低了氧化铝的含量，镁－铁铝尖晶石砖和镁－锰铝尖晶石

砖的抗拉强度依然要比传统的顶级镁铝尖晶石砖高很多，即使在

高温下亦是如此。

楔形劈裂实验：这种测试方法可可以测定耐火材料在高温下(1100到1250 °C)的机械断裂参数，表征耐火材料抗高温机械断裂的能

Magnesia

Active spinel

FeAl2O4

Active spinel technologyHercynite (Fe/Al spinel) as well as galaxite (Mn/Al spinel) represent so-called “active spinels”. Just like MA-spinel, hercynite and galaxite cause a thermal misfit which results from its lower thermal expansion compared to the surrounding magnesia-matrix. Additionally, there are diffusion processes of Fe2+ (Mn2+)-ions into the matrix leading to a surplus of alumina within the hercynite grain. Furthermore, Mg2+-ions diffuse into the hercynite grains. The supplied magnesium reacts with the surplus alumina from the hercynite forming in-situ secondary spinel. This reaction entails an additional volume expansion and, therefore, additional flexibility. This flexibility effect of the active spinel is maintained during the service period (active spinel) due to the continuous process of iron and magnesium diffusion.

活性尖晶石技术

电熔合成的铁铝尖晶石(Fe/Al 尖晶石)和锰铝尖晶石(Mn/Al 尖晶

石)是奥镁公司的专利产品，通常被称为“活性尖晶石”。将活

性尖晶石引入镁质耐火材料中，一方面和常用的镁铝尖晶石作用

类似，在高温使用过程中由于它们的热膨胀系数小于氧化镁基质

的热膨胀系数因而在尖晶石颗粒周围形成空隙，起到阻断基质中

裂纹扩展的作用。另一方面这些尖晶石中的Fe2+ (Mn2+)-离子和基

质中的二价镁离子发生交互扩散，铁离子在周围氧化镁基质中持

续扩散；镁离子进入尖晶石结构中并占据铁（或锰）离子原来的

位置，与因铁（或锰）离子扩散失去而过剩的氧化铝反应生成原

位镁铝尖晶石。这一反应的体积效应又进一步提高了镁质耐火材

料的结构柔韧性。这样的离子交互扩散行为在高温下持续进行。

因此，活性尖晶石的柔韧化效应贯穿于氧化镁－铁铝尖晶石耐火

材料在水泥回转窑高温使用过程中。

活性尖晶石技术可以使镁质耐火材料在减少Al2O3加入量情况下达

到比通常镁铝尖晶石耐火材料更好的结构柔韧性。这样在达到和

镁铝尖晶石砖同等结构柔韧性的同时，降低了“活性尖晶石”的

添加量。通常镁铝尖晶石砖中的氧化铝会与渗入的水泥熟料液相

反应会生成低熔点的铝酸钙，因此，采用活性尖晶石技术降低镁

质耐火材料中的氧化铝含量，有利于提高耐火材料的抗熟料液相

和碱盐以及热侵蚀的能力。

The introduction of the active spinel technology allows to reduce the Al2O3 content compared to common bricks containing MA-spinel. This results from the lower amount of “active spinel” needed to provide the same microstructural flexibility as for MA-spinel bricks. As Al2O3 forms low-melting calcium-alumi-nates in case of clinker-melt infiltration into MA-spinel bricks, the lower content of alumina has a positive effect on the corrosion resistance, hot erosion strength and alkalis resistance of the brick.

Now RHI’s premium grade magnesia spinel and hercynite bricks, based on purest high-grade sintered magnesia, are also available from Dalian. RHI being the first refractory supplier able to produce high grade raw materials in China and manu-facture high grade products in China. This top-grade sintered magnesia is charac-terized by very low amounts of secondary oxides such as CaO, SiO2 and Fe2O3.This leads to a further significant improvement of corrosion resistance compared to the already high grade bricks ANKRAL RC or ANKRAL ZC which are based on high-grade natural sintered magnesia. As a result of the outstanding properties, these products are offered as problem- solvers for kilns with a particularly inten-sive chemo-thermal load as, for example, is the case if using high amounts of alternative fuels.

AnKRAL R1 (mA Spinel)RHI’s premium grade with highest refractoriness, ANKRAL R1, consists of pure sintered high-grade magnesia and so-called in-situ spinel plus an addition of calcined alumina. Due to the “in-situ spinel technology” and its high purity, ANKRAL R1 spinel bricks have an excellent resistance to very high thermal stress and to alkali-salt and sulfate attacks. The low Al2O3 content makes this brick type specifically resistant to infiltration by clinker melt. Although ANKRAL R1 consists of high purity raw materials, its specially designed microstructure gives the brick a high self-coating readiness, thus promoting safe coating and better infiltration resistance.

AnKRAL R2 (mA Spinel)Just like ANKRAL R1, the ANKRAL R2 brick grade is based on very pure high-grade sintered magnesia. In contrast to ANKRAL R1, ANKRAL R2 contains pre-fabricated fused spinel. This pure MA spinel brick type, with its coating-repellent behavior, has been specially designed for areas with changing coating conditions and frequent thermal shock. Apart from this, ANKRAL R2 has an excellent resistance to alkali-salt and sulfur attacks and was developed for kilns with severe operation conditions.

AnKRAL Z1 (Hercynite)This brick grade represents a new generation of “heavy duty” cement rotary kiln bricks based on purest high-grade sintered magnesia and fused hercynite spinel. This innovative raw material concept gives ANKRAL Z1 superb refractoriness and corrosion resistance as well as outstanding structural flexibility due to the addition of the patented fused hercynite. ANKRAL Z1 is characterized by a very low apparent porosity which ensures a very low tendency of infiltration by alkaline salts or liquid clinker melt. An essential feature of this premium grade hercynite spinel brick is its ability to form coating which is not typical for premium grade spinel bricks. The positive effects of this protective mechanism on service life and kiln shell temperature are not achieved by conventional MA spinel bricks.

AnKRAL R8 (mA Spinel)Is based on purest high grade sintered magnesia and fused MA spinel. The raw material mix with increased amount of fused spinel leads to an outstanding flexibility in combination with a high resistance to chemical attack by alkaline salts. It has been designed for the use in transition zones of kilns with high chemo-thermal load.

AnKRAL RC (mA Spinel)ANKRAL RC is made from high-grade natural sintered magnesia and pre-fabricated fused MA-spinel. Outstanding properties ensure the superb resistance to alkali and sulfur attack and, furthermore, high mechanical flexibility. It can be installed in the lower and upper transition zones where there is no stable protective coating.

AnKRAL ZC (Hercynite)ANKRAL ZC is another member of the “active spinel technology” product family based on fused hercynite, burnt natural magnesia and a special firing technology. The use of fused hercynite gives the brick unique properties such as the ability to form coating, excellent refractoriness, high micro-structural flexibility as well as very good resistance to chemical attack with low thermal conductivity. The use of synthetic fused hercynite has been patented by RHI.

AnKRAL ZF (Hercynite)The newest brand ANKRAL ZF has been especially designed to withstand high mechanical stresses in combination with chemical load. It is based on high grade natural sintered magnesia and the patented hercynite spinel, which is success-fully used in ANKRAL ZC. The outstanding flexibility is achieved by the combina-tion with a further flexibilizer and an optimized microstructure. Due to the use of hercynite this bricks also has a high ability to form coating. The unique raw material concept furthermore imparts this brick a high resistance to chemical attack with low thermal conductivity. It can be recommended for the lining of the whole basic section of the rotary kiln.

AnKRAL DC (Chromite)This brick type is based on high grade natural sintered magnesia and chromite. ANKRAL DC combines excellent micro structural flexibility with a high ability to form a stable coating which protects the brick from thermal and chemical load. Under normal process conditions this brick can be therefore recommended for the entire basic zone of cement rotary kilns. A further advantage is the low thermal conductivity which helps to reduce kiln shell temperatures and minimize the energy losses.

100% Inspection of each brickIn addition to the ISO quality control system, the Dalian plant has implemented the so-called ANKRAL TEST LINE to monitor the quality of each brick. After a visual check the brick enters the ANKRAL TEST LINE where it passes an ultrasonic test, laser beam measuring and x-ray test. Based on this the modulus of elasticity, bulk density and cold crushing strength are calculated. In summary, RHI bricks offer double safety for customers. They are produced according to ISO 9001 and ISO 14001 quality assurance certification procedures and each brick is tested by a non-destructive method. These are unique safety features only offered by RHI.
