没计了一套适合于制备高熔点钢铁材料半固态流变浆料的装置,这种装置不仅能制备含非枝晶状初生固相的半固态流变浆料,而且能将这种半固态浆料输送出来,满足后续的钢铁材料半固态浆料流变轧制的需要。本装置主要由电磁搅拌器、搅拌坩埚预热和保温系统、半固态浆料输送系统和其他辅助结构组成。采用电阻丝加热方法对搅拌坩埚进行预热和保温,控制钢水或铁水在坩埚中的冷却速度;采用旋转磁场型电磁搅拌器对搅拌坩埚中的金属液体进行连续的电磁搅拌,制备出初生相或先析出相为球状或近球状的半固态流变浆料;采用底漏式坩埚和塞杆及其提升机构对半固态流变浆料进行输送,半固态浆料在重力作用下经过搅拌坩埚底部的水口流出。
Not counting a set of suitable for preparing high-melting steel semi-solid rheological slurry device, this device can not only prepare non-dendritic primary solid phase semi-solid rheological slurry, but also this semi-solid The slurry is conveyed out to meet the needs of the follow-up semi-solid slurry rheo-rolling of steel materials. The device is mainly composed of electromagnetic stirrer, stirring crucible preheating and insulation system, semi-solid slurry conveying system and other auxiliary structures. Using a heating method of resistance wire to preheat and heat the stirring crucible to control the cooling rate of the molten steel or molten iron in the crucible; using a rotating magnetic field-type electromagnetic stirrer to continuously electromagnetically stir the metal liquid in the stirring crucible to prepare a primary phase or First precipitated phase spherical or nearly spherical semi-solid rheological slurry; the use of bottom-drain crucible and rod and its lifting mechanism for conveying semi-solid rheological slurry, semi-solid slurry under gravity through the bottom of the stirring crucible Out of the outlet.
