1 绪言近年来,连铸-热轧之间的直接连接技术取得了显著的进步,无缺陷铸坯制造技术的确立是其发展的前提条件,本文在阐述高温铸坯制造技术的同时,也对防止铸坯在高温情况下重新产生裂纹的措施进行了介绍。2 关于高温铸坯制造的基本设想
INTRODUCTION In recent years, the direct connection technology between continuous casting and hot rolling has made remarkable progress. The establishment of defect-free slab manufacturing technology is a prerequisite for its development. This paper expounds the manufacturing technology of high-temperature slab, The measures to prevent the slab from re-generating cracks under high temperature were introduced. 2 basic ideas on the manufacture of high temperature slab
