摘　　要：研究了冷却速率和硅、锰合金元素含量对Fe—C合金的包晶反应和包晶点位置的影响；由于CSP薄板坯冷却速率快，Fe—C相图向左下方移动，包晶反应区域的碳含量为0．08％-0．20％；在钢中其它成分不变的条件下，硅含量增加，锰含量减少，包晶点处的碳含量会提高。It is researched the influence of cooling rate and the Content of silicon and manganese alloy on peritectic reaction and position of peritectic point in Fe - C alloy. The C content is about from 0.08% to 0.20% in peritectic reaction region because the cooling rate of CSP thin slab is faster and its Fe - C phase diagram moves to the down left; with other components keeping not changed the C content at peritectic point would increases while silicon content up and manganese down.
