Such specimens could not be remedied by the usual quench andtemper treatment, and re-solution treatment at high temperatures (980-1050℃)followed by rapid cooling to room temperature was necessary to modify the sizeand distribution of the boron-containing phase, with the consequence of improvingproperties and eliminating the shell-shaped fracture.
对于出现&壳层状硼脆断口&的50B钢,正常的调质处理不能恢复其性能。但在980—1050℃重新固溶处理并以较快速率冷却到室温则可以改变硼相的析出形态,并改变相应的断口形态,相应地性能也恢复或有所提高。

Moreover, the electromagnetic flux density and meniscus height increase in the form of chequerboard with increasing of slit number. The numerical results can exactly illuminate some experimental phenomena, and enrich the theoretical foundation of soft-contact continuous casting technology. In practice, a softcontact mold with slit number of 16 or 24 is recommended, the suggested frequency is around 20kHz, and the slit width is about 1mm.
结果表明:钢液对结晶器内的电磁场分布有很大影响;发现了磁感应强度和弯月面高度随电源频率增加而增大的频率范围、磁感应强度和弯月面高度随切缝数目增加呈&锯齿状&增大的规律;研究结果合理地解释了一些实验现象,完善了软接触结晶器电磁连铸技术的理论基础;建议在实际应用中采用分瓣数为16或24分瓣数的结晶器,电源频率应控制在20kHz左右,切缝宽度应控制在1mm左右。
