Indian Standard SPECIFICATION FOR

ZIRCON FLOUR FOR USE IN FOUNDRIES

( First Revision )

0. FOREWORD

0.1 This Indian Standard ( First Revision ) was adopted by the Indian Standards Institution on 30 December 1974, after the draft finalized by the Foundry Sectional Committee had been approved by the Structural and Metals Division Council.

0.2 This standard was first published in 1969. As a result of experience gained during these years, it has been decided to revise this standard. In this revision the following main m&&ions have been made:

a) Clause on grain fineness has been modified for grade 2 ( now desig nated as F-150 ), and

b) Amendment No. 1 issued earlier has been incorporated.

0.3 Zircon is a high refractory material. It is used primarily in the steel foundry as dressing for moulds and cores as also for adding to moulding sand mixtures.

0.4 This standard keeps in view the manufacturing and trade practices followed in the country in this field.

OJ For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.

1. SCOPE

1.1 This standard covers the requirements for zircon flour for use in foundries.

2. SUPPLY OF MATERIAL

2.1 General requirements relating to the supply of zircon flour for use in foundries shall be as laid down in IS : 1387-1967t.

*Rules for rounding ofT numerical valua ( recked ).

tGeneral req uirallalts for the supply of metallurgical materials (firsl reuisiun ).

Is:5383-1974

3. SAMPLING

3.1 Representative sampks shall be drawn according to the scheme of sampling given in IS : 181 l-1961*.

4. MANUFACTCJRE

4.1 Zircon flour shah be produced by crushing, washing and grading zircon sand.

5. CHEMICAL COMPOSITION

5.1 Zircon flour shah have the following chemical composition on dry weight basis :

Constituent Rquirement, ptmmt

ZrO, 64 Min SiOz 30 to 35 TiOp + Fe&s 0.5 Max

NOTE-‘ Indian Standard method of chemical analysis of zircon flour for use in foundries ’ is at present under preparation. Till this standard is published, the methods of chemical analysis of zircon flour shall be as agreed to between the purchaser and the supplier.

6. SPECIFIC GRAVITY

6.1 The specific gravity of zircon flour shah be between 4.4 and 4.7.

7. FUSION POINT

7.1 When tested in accordance with the method given in IS: 1918-1966t, the fusion temperature of zircon flour shah not be below 2 000°C.

8. GRAIN FINENESS

8.1 Depending on the fineness of grain, there shall be two grades of the material, namely, F-75 and F-150. In the case of F-75, the material shall completely pass through 79micron IS Sieve and in the case of F-150, 100 percent material shall pass through 150micron IS Sieve and at least 90 per- cent of the material shah pass through 75-micron IS Sieve. The grain fineness of the material shall be determined in accordance with the method given in IS: 1918-1966t.

NOTE 1 -The aperture of BS Sieve 200 and 100 and ASTM Sieve 200 and 100 are within the limits laid down for the 1S Sieves and may, therefore, be used as 75-micron and 150-micron IS Sieves.

*Method of sampling foundry sands.

tMethods of physical tests for foundry sands.

IS : 5303 - 1974

NOTE 2 -Material of F-75 is normally used for the preparation of foundry washes andmataialofF-150isuPedforfoundrysandmiug.

9. PACKING

9.1 Unless specified otherwise, zircon flour shall be supplied in polythene lined gunny bags each containing 50 kg.

10. MARKING

10.1 The bags containing zircon flour shall be clearly marked with the grade of the material and the manufacturer’s name or trade-mark.

10.1.1 The material may also be marked with the IS1 Certification Mark.

NOTE -The use of the IS1 Certification Mark is governed by the provisions of the Indian Standards Institution ( Certification Marks ) Act and the Rules and Regulations made thueunder. The IS1 mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well-del%xd system of inspection, testing and quality control which is devised and supervised by IS1 and operated by the producer. IS1 marked products are also continu- ously c&&d by IS1 for conformity to that standard as a further safeguard. Details of. conditions under which a licence for the use of the IS1 Certification Mark may be granted to manufacturers or processors, may ,be obtained from the Indian Standards Institution.
