RELIABLE IN HARSH ENVIRONMENTS

In the steel industry, measurement systems have to prove reliable every day under difficult operating conditions. Through decades of experience, our engineers understand these conditions and know how to protect measurement systems to keep them working. Outstanding sensor technology, mechanical stability, shock and dirt resistance, thermal insulation, cooling systems, and easy maintenance contribute to the overall performance of the systems.

MORE THAN JUST SENSORS

Specific needs of production processes and related production lines often require individual adaptation of a measurement system. Because of this we offer single source systems, from sensors through mechanics, electronics to software, and finally integration into the process. You are dealing with a single contact and clear responsibilities during the entire project. Close cooperation between LAP and their customers guarantees short installation cycles and high operator acceptance.

LEADING IN NEW TECHNOLOGIES

Quality demands on flat and long products are rising continually. Consequently, LAP is permanently refining and developing its systems. The RDMS profile gauge as an example is worldwide accepted to measure the true profile of long prod-ucts. It‘s patented technology detects and measures all relevant shape defects precisely, namely three-lobed shapes and asymmetric fill. This patented technol-ogy provides reliable data for modern rolling technologies such as 3-roll stands.

LAP – MEASUREMENT ENGINEERING FOR THE STEEL INDUSTRY

For more than 20 years, LAP systems have been measuring dimensions of long and flat products in production lines. We manufacture laser based systems for non-contact measurement of position, width, thickness, diameter, contour and shape for the entire process chain, from continuous casting to the finished product. Careful assessment of customer requirements, from management to the operator level, of plant conditions and operating procedures, is essential to engineer and implement well thought-out solutions. Any project begins with the thorough understanding of customer needs.

WORLDWIDE, MORE THAN 200 LAP SYSTEMS ARE SUCCESSFULLY IN USE

WHY ARE WE SUCCESSFUL? WE LISTEN TO OUR CUSTOMERS.

LAP measuring systems help to raise the quality of your products, increase the throughput of your plant, and improve the efficiency of your production. Ask us to measure any dimension of long or flat products – we will find a solution.

STRIP PROCESSING

LAP systems will optimize the casting process and control the cut-to-length operation. Precise readings of slab width, side profi le, thickness, and length allow exact determination of the slab weight and to document the output of the caster. In subsequent production stages these slabs can then be easily allocated to the customer orders on hand. Measurement of the slab position on the charging side and inside of the reheat furnace ensures optimal positioning of the slabs and maximizes throughput of the furnace.

LAP systems measure dimensions through all production stages from the slab to the fi nished plate. Length, width, taper, necking and curvature results are available immediately, and are archived for each plate. The

LAP Croptimizer minimizes the crop losses, optimizing the yield of every rolled plate and opti mally allocating the plates to the customer.

STRIP ROLLING

Measuring the strip geometry in hot and cold rolling with LAP measure-ment systems allows mills to produce strip to the exact dimensional and fl atness specifi cations of the customer, resulting in a smooth and effi cient operation. Laser Sensors mounted at the coilers precisely measure diameter and side profi le of the coils. LAP systems utilize optical sensors to measure thickness, width, speed, etc. They can be installed with minimal eff ort, and do not require expensive safety precautions as some technologies.

Regardless if you are annealing, hot dip galvanizing, or coating in strip processing lines, width, thickness and fl atness are essential quality parameters. Measurement of sag allows precise control of the strip run and can therefore op timize the strip treatment. On exit of the plant, all strip dimensions and fl at-ness are completely documented.

CONTINUOUS CASTING

LAP systems are used for measuring the thickness, width, and length of the continuous casting strand to determine dimensional correctness. The results of these measurements will be used to optimize the casting process and to control the cut-tolength operation for slabs and billets. Measuring the position of the billet before it enters the reheat furnace helps to control the charging of the billet, optimiz-ing furnace utilization and reducing the possibility of misaligned slabs.

LAP RDMS Profi le Measuring Systems provide all the information needed for fast and precise adjustment of rolling lines. They can measure not only rounds, but also rebar, fl ats, squares, hexagons and angles. The patented TrueShape technology allows precise measurement of three-lobed or polygonal rounds, and of single-sided over- or underfi ll. Off -size conditions are immediately displayed and allow corrections during runtime of a billet. Elimination of sample cutting reduces the ramp-up time after size or product change. Precise determination of off -size lengths at head and tail allows crop-optimization, further increasing the yield.

TUBES

LAP systems measure the OD of tubes in the rolling line. Measurement of diameter in two or three axes also yields precise ovality readings, avoiding costly post-processing. The result of this is that a greater percent-age of the tubes being produced meet the specifi cation that are required by the customers. Producing to tighter specifi cations also increases the yield ratio. LAP measurement systems for fi nal inspection of tubes before shipment provide essential data for quality assurance.
