In present study , a proposal to improve the inclusion floatation and temperature homogenization of molten steel is presented through an optimizing study by water modeling 通过优化设计,提出了促进夹杂物上浮和均匀中间包内钢水温度的设计方案。
Abstract : water modeling of the six - strand caster tundish shows that the original design of the tundish can not meet the technical requirements for inclusion floatation and temperature homogenization 文摘:通过水力学模拟六流连铸中间包后发现,原设计的中间包在夹杂物的上浮及温度的均匀性方面还存在不足,不能很好地满足生产工艺要求。
The phase composition and microstructure of sm - fe - zr alloy with different amount of zr are analyzed and the effect of zr content on the microstructure of as - cast sm - fe - zr alloy is studied . the results indicate that microstructure of as - cast sm - fe - zr alloy is improved obviously with 1 . 0at % zr added , and that the long - time high temperature homogenization is unnecessary for the alloys with this microstructure . by this way , the purpose of the research to decrease the cost of preparation and optimize process is achieved 分析了不同zr含量的sm - fe - zr合金的相组成和微结构,研究了zr含量对铸态组织的影响,结果表明,添加1 . 0at的zr可以明显改善合金的铸态组织,从而可以避免昂长的高温均匀化退火过程,取得了降低制造成本和优化工艺的效果。
