研制MgO-CaO坩埚的目的是降低MgO的高温不稳定性对合金造成的影响,同时发挥CaO具有的高温稳定性和脱硫等作用的特点,实现MgO、CaO互补,满足真空冶炼的要求,同时降低坩埚的成本。
The purpose of developing the MgO-CaO crucible is to reduce the influence of the high temperature instability of MgO on the alloy, and at the same time exert the high temperature stability and desulphurization effect of CaO so as to realize the complementation of MgO and CaO, meet the requirements of vacuum smelting and reduce Crucible costs.
