This paper introduced the advantages to produce semi-solid alloy by using the inclined cooling plate such as its short flow,low cost,simple equipment,high production efficiency,and it can produce big size roughcast.
介紹了傾斜冷卻板法制備半固態(tài)合金流程短、成本低、設(shè)備簡(jiǎn)單、生產(chǎn)效率高,同時(shí)又能生產(chǎn)較大尺寸的半固態(tài)坯料等的特點(diǎn),指出了傾斜冷卻板法制備半固態(tài)合金的原理及其影響因素,并闡述了傾斜冷卻板法在半固態(tài)加工中的應(yīng)用及其應(yīng)用前景。
The results show that the optimum gap between roll and shoe varies in 2～3?mm; pouring temperature can affect grain size and its shape of semi solid alloy.
利用自行設(shè)計(jì)的單輥剪切 /冷卻 (SCR)試驗(yàn)機(jī)對(duì)LY11合金進(jìn)行了半固態(tài)凝固實(shí)驗(yàn) ,研究了工藝條件對(duì)LY11半固態(tài)合金組織的影響。
The results indicate that the transient peak of apparent viscosity of semi solid alloys increases with expanding the rest time under the same experimental conditions.
結(jié)果表明 ,在相同的剪切條件下 ,隨剪切停留時(shí)間的增加 ,瞬時(shí)峰值表觀粘度增加 ,說明剪切停留期間半固態(tài)合金初生α相形態(tài)發(fā)生了變化 ;對(duì)半固態(tài)合金初生相形態(tài)觀察發(fā)現(xiàn) ,剪切停留促使初生相發(fā)生了“團(tuán)聚”或“合并” ,而且初生相形態(tài)變化的程度取決于剪切停留時(shí)間和初生相的退化程度 。
