Abstract

摘要

熔体中B的损失主要在加B后的合金化过程

其次是铸造时熔体的保温过程

在工艺上加强脱氧和覆盖

可以比较合理地控制B含量 ;在保温铸造过程中B有向表面迁移聚集的倾向 ;w（B） =0 .0 13 %时

对铸态组织有明显细化作用

高倍组织发现针状相和块状相

B含量较低时

未发现针状相

块状相经电子探针X射线扫描分析

是一种含有合金元素As和其他杂质的富B化合物

熔体对硅砂炉衬侵蚀严重。

B loss in melt mainly occures in B addition followed by alloying process

next at melt holding during smelting and pouring.The B content can be rationally controled with enhancing deoxidation and coverage.B trends towards surface coagulation at melt holding during pouring. w （B） =0.013% can refine greatly as cast microstructure

with occurence of needle like and block like phase in high magification while no needle like phases occur in lower B content.It is founded that the block like phase consits of a rich in B coumpound with As and other inpurities by DEX.Melt strongly erodes silica sand lining.
