Leveling unit

Our 1500 single-stand four-roll leveller equipment is manufactured by China First Heavy Machinery Co., Ltd., with an annual production capacity of 500,000 tons, and can produce 0.2-2.0mm cold-drawn boards, with a product width of 800-1350mm. The cold-rolled steel coils were flattened in a 1500 single-rack four-roll smoother after being annealed by a hood annealing furnace. The unit equipment adopts AC variable frequency motor drive, digital speed control system, hydraulic pressure roll gap, pressure, elongation control, work roll positive and negative bending roll control system and imported laser speed control system to adjust and improve. Improve the surface roughness, shape and other mechanical properties of the coil, eliminate the slip line of the cold rolled coil, and ensure the quality of the product.
