前言随着市场经济的飞速发展,汽车、仪器仪表、无线电、国防及航空航天工业等尖端技术领域对带钢的品种、规格、性能和质量不断提出更高的要求,在带钢生产上冷轧较热轧更能满足各行各业发展的需要。当生产厚度减小到一定尺寸的薄带钢时,大多数都采用冷轧方式。现代带钢生产,大多是热轧后又进行冷轧,为提高带钢表面质量、改善力学性能和获得精确的尺寸偏差提供了保证。 Preface With the rapid development of the market economy, cutting-edge technologies such as automotive, instrumentation, radio, defense and aerospace industries continue to place higher demands on the varieties, specifications, performance and quality of steel strip, More hot-rolled to better meet the needs of all walks of life. When producing thin strip of reduced thickness to a certain size, most are cold rolled. Modern strip production, mostly hot rolled and then cold rolled, provides a guarantee for improving strip surface quality, improving mechanical properties and obtaining precise dimensional deviations.
