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 通過(guò)優(yōu)化設(shè)計(jì),提出了促進(jìn)夾雜物上浮和均勻中間包內(nèi)鋼水溫度的設(shè)計(jì)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:通過(guò)水力學(xué)模擬六流連鑄中間包后發(fā)現(xiàn),原設(shè)計(jì)的中間包在夾雜物的上浮及溫度的均勻性方面還存在不足,不能很好地滿足生產(chǎn)工藝要求。
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合金的相組成和微結(jié)構(gòu),研究了zr含量對(duì)鑄態(tài)組織的影響,結(jié)果表明,添加1 . 0at的zr可以明顯改善合金的鑄態(tài)組織,從而可以避免昂長(zhǎng)的高溫均勻化退火過(guò)程,取得了降低制造成本和優(yōu)化工藝的效果。
