中文摘要：
A 小说演员组处理方法，自我接种方法(SIM ) ，被建议。这个过程包含自我种体的增加融化，然后通过混合冷却的一条多溪流倒 melt 到一个模子隧道。在这份报纸，进程参数被调查。结果显示 melt 处理温度，增加的自我种体的数量，和冷却隧道的斜坡角度是为 SIM 过程的关键因素。优化参数是 melt 处理温度在 680 和 700 之间；自我种体的增加在 5wt .% 和 7wt .% 之间；并且冷却隧道的斜坡角度在 300 和 450 之间。进一步的分析表明 SIM 由在 melt 控制主要阶段的成核和生长改变泥浆的团结微观结构。
英文摘要：
A novel cast processing method,self-inoculation method （SIM）,was proposed.The process involves the addition of self-inoculant to melt,then pouring the melt to a mould through a multi-stream mixing cooling channel.In this paper,the process parameters were investigated.Results indicate that the melt treatment temperature,the amount of self-inoculant added,and the slope angle of the cooling channel are the key factors for SIM process.The optimized parameters are that the melt treatment temperature is between 680 and 700°C;the addition of self-inoculant is between 5wt.% and 7wt.%;and the slope angle of the cooling channel is between 30° and 45°.Further analysis reveals that SIM changes the solidification microstructure of slurry by controlling the nucleation and growth of the primary phase in the melt.
