对≤ 30 mm的几种小直径棒坯进行了水平连铸生产试验。结果表明 ,小棒坯具有更细密的组织和优良的性能。通过热处理消除连铸小棒坯铸态白口组织的工艺路线可行且可靠。
For several 直30 mm small diameter billets horizontal continuous casting production test. The results show that the billet has more fine structure and excellent properties. The process route of eliminating the as-cast white-stained structure of continuous casting billet by heat treatment is feasible and reliable.
