1 绪言1.1 厚板的定义厚板的定义在各国不同。在苏联、日本和西德没有中厚板之分,统称热轧钢板。苏联 19903—74标准规定:宽度≥500mm,厚度为0.5～160mm 的板材统称热轧钢板。日本 JISG3193(1977)定义钢板为热轧成钢而以平板状态供应的钢材,包括从钢带的切板,但扁钢及用于再轧材料的钢片不做为钢板处理,标准厚度为1.2～50mm。西德 DIN1543(1977)标准适用于厚3～150mm 的热轧钢板,但它还有 DIN1542(1977)标准适用于厚3～4.75mm 的热轧中板。在美国、从板材的尺寸和重量范
1 INTRODUCTION 1.1 Definition of slabs The definition of slabs varies from country to country. In the Soviet Union, Japan and West Germany no plate, collectively referred to as hot-rolled steel. The Soviet Union 19903-74 standard: width ≥ 500mm, the thickness of 0.5 ~ 160mm plate collectively referred to hot-rolled steel. Japanese JISG3193 (1977) defines steel as hot-rolled steel and slab-supplied steel, including the strip from the strip, but the flat steel and re-rolled steel sheet is not treated as a steel plate, the standard thickness of 1.2 ~ 50mm. West Germany DIN1543 (1977) standard for hot-rolled steel plate thickness 3 ~ 150mm, but it also DIN1542 (1977) standard for 3 ~ 4.75mm thick hot-rolled plate. In the United States, the size and weight of the plate range
