一、前言从西德引进的五机架连轧机组,主要用来轧制低碳钢,来料强度极限不超过42公斤/毫米~2。WSPA钢属于低合金钢,材料强度极限一般都在50～58公斤/毫米~2,大大超过了轧机的许用条件。为了保证设备的安全,能否将3.0×1100毫米的热轧板冷轧到1.5×1100毫米,需要事先对WSPA钢进行冷连轧轧制实验和轧制压力的核定计算,从而为冷连轧轧制WSPA钢提供一定的技术参数和生产的可行性。
I. INTRODUCTION The five-stand continuous rolling mill introduced from West Germany is mainly used for rolling low-carbon steel with the limit of incoming strength not exceeding 42 kg / mm ~ 2. WSPA steel is low alloy steel, the material strength limit is generally 50 to 58 kg / mm ~ 2, greatly exceeded the mill’s allowable conditions. In order to ensure the safety of the equipment, whether the 3.0 × 1100mm hot-rolled sheet can be cold-rolled to 1.5 × 1100mm, the cold-rolling test of WSPA steel and the verification of rolling pressure need to be calculated in advance, Rolling WSPA steel to provide a certain technical parameters and the feasibility of production.
