The effect of chemical composition and cooling process on microstructure and mechanical properties of specimens taken from the controlled rolled and cooled strips of vacuum melted multiphase and martensite steels were researched. 在实验室用真空感应炉冶炼复相钢和马氏体钢,锻坯、控轧成3mm厚的板材后采用不同冷却模式进行控制冷却。研究了成分、冷却工艺对组织与力学性能的影响。
The gasket material for the vacuum has melted and was not made for high temperatures. 真空密封垫圈材料被熔化,并不是采用耐高温材料;
Abstract The paper introduces test prodUcing high-Ti ferro-titanium according with the quality demands with waste titanium and mild steel in vacuum induction furnace of rough vacuum and melted magnesite pot. 在真空感应炉的低真空度条件下,采用电熔镁砂坩埚.以残钛和低碳钢为原料试生产出符合质量要求的高钛钛铁。
An Investigation on Vacuum Degassing of Melted Copper 铜液真空处理的研究
The pores near surface may suck up water from outside in the heating stage of freeze-thaw cycles owing to the vacuum caused by the decrease in volume of water when melted. 接近表面的孔隙在融解阶段可从外部吸水,原因在于冰融解后体积减小,在孔隙中形成负压。
