The improvement of immersion nozzle in square billet caster is introduced, the result extinguished. 介绍了邯钢方坯连铸机浸入式水口的改进,保护浇注效果显著。
The effects of different nozzle outlet angle, immersion depth of SEN and casting speed on the flow field were ascertained and suitable nozzle structure for the mold was established. 研究了不同水口倾角、插入深度及拉速等参数条件对结晶器内流场的影响,得出了适用于宽规格结晶器合理的浸入式水口。
The frequency of vortex increases with the augment of the casting speed, and decreases with the augment of the immersion depth and nozzle angle. 漩涡的出现频率随拉速的增加而增加,随水口浸入深度的增加而减小,随水口张角的减小而增大;
Study and Application on the equipment of high-speed changing immersion nozzle 浸入式水口快速更换装置的研究与应用
Control of heat and mass transport in continuous casting mold through swirling flow in immersion nozzle 通过浸入式水口中的旋流控制连铸结晶器中热量和质量的传输
The other is from 9 to 10 mm which comes from the blockage matrix of the immersion nozzle. Some measures for improving casting quality are also presented. 另一个在9~10mm处,主要来源于浸入式水口脱落物.文中提出了相应的解决措施。
Through simulation and computation with the established simulation model, influences of such as casting speed, tilt angle of the nozzle port, immersion depth of the nozzle tube, size of nozzle port on flow field and temperature field in the mold were analyzed. 通过计算机模拟,分析了拉速、水口出口角度、插入深度、水口出口面积比等参数对结晶器内的流场和温度场的影响。
