Cooling line also suitable for other products High strength values: • Yield point : 500 Nmm2 • Tensile strength: 560 Nmm2 • Elongation percentage grade: 12% Other data: • Final rolling temperature: 950-1050°C • Equalizing temperature at laying head: 650°C • Water pressure, max: 1.6 Mpa • Max product speed, approx: 80 ms

The design of knife carrier will be adopted to the required application, e.g.: One knife track, one knife: cropping, dividing (e.g. cooling bed lengths) Low temperature rolling One knife track, two knives: cropping; emergency cutting One knife track, various knives short emergency lengths Two knife tracks, with additional switch: 1st track one knife: cropping, dividing 2nd track various knives: short emergency lengths Shear start is initiated by pulse generator (billet head end) Cut according to chosen crop length After cutting, the shear is stopped again Crop end diverted into scrap disposal system

Crank lever shears working as start-stop-shears and adopt the crank-and-rocker principle of operation. Whilst performing the shearing operation the knives are almost perpendicular to the stock to be cut. This shears are suited to crop, cut sections and cooling bed lengths as well as for emergency cutting.

ROD MILL BLOCK - The field-proven unit Modern rod mill processes are characterized by high productivity. The material is shaped at high mill delivery speeds and low product temperatures to obtain defined metallurgical effects, entailing high requirements to be met by the equipment. Therefore, the rod mill blocks operating in the high-speed range are of a particularly rugged design. Our Rod mill blocks feature Product speeds up to 100 ms (designed for 120 ms) through optimized mechanisms. Low gear speeds compared to roll speeds. Roll forces and roll torques designed for low temperature rolling. Large spaces to accommodate antifriction and friction bearings. Gear shafts supported in heavy-duty cylindrical roller bearings of special cage design and in precision angular-contact ball bearings. Five-year preventive maintenance intervals for gear units and power dividers.
