转炉MgO-C砖粘渣试验研究

Experimental Sudies on Bonding Slag for Converter MgO-C Lining

在实验室条件下通过调整转炉终渣成分进行MgO-C砖的粘渣试验表明:在终渣碱度变化不大的情况下,适当降低终渣的∑FeOn,将MgO和终渣熔点控制在一定范围内,能得到较厚且结合牢固的粘渣层。同时,观察到在MgO-C砖工作面形成一定的脱碳层,对粘渣是有利的。

Under the laboratory conditions experiments on the bonding slag for MgO-C lining have been conducted by adjusting the compositions of the end point slag. Testing results show that a thicker and well bonded layer can be formed providing that the ∑FeOn content is properly reduced and MgO content and melting point is controlled in a specified limit under the condition of the constant basicity of the end point slag. In the meanwhile it is observed that formation of a decarburized zone on the working face of MgO-C lining is advantageous to the bonding slag.
