一前言消化国外引进设备,吸取其优点,为改进我国自行设计、制造的连铸设备提供参考意见,我们于80年6月前后在武钢,上钢一厂,分别取了大量的连铸板坯试样作了对比研究。由于凝固组织反映了凝固条件。在两厂取样时,尽量使其生产条件相近以减少对凝固组织的影响。有利于找出两厂设备、工艺的差异,及其对凝固组织的影响,改善凝固条件,获得所希望的凝固组织,从而达到改进铸坯质量的目的。
A preamble to digest the introduction of foreign equipment, learn from its advantages, to improve China’s own design, manufacture of continuous casting equipment to provide reference, we in about 80 years in Wuhan Iron and Steel, a steel plant, respectively, took a lot of continuous casting slab The samples were compared. Due to the solidified tissue reflects the solidification conditions. In the two plants sampling, try to make their production conditions similar to reduce the impact on the solidified tissue. It is helpful to find out the difference between equipment and technology in two plants and its influence on the solidified structure, to improve the solidification conditions and to obtain the desired solidified structure so as to achieve the purpose of improving the quality of the slab.
