不同碱度精炼渣对镁碳耐火材料的侵蚀行为
Erosion Behavior of Refining Slag with Different Basicities on Magnesia-Carbon Refractories
摘要
Abstract
Three types refining slag with different basicities(R=0.8,1.0,and 1.2)were prepared.The influence of basicity on resistance to slag erosion of MgO-C bricks was systematically investigated using thermodynamic calculations,surface tension measurements and dynamic anti-slag test.The results show that with the increase of basicity,the viscosity of slag decreases and the surface tension increases significantly.In refining slag S1(R=0.8),higher solubility of MgO results in more severe erosion of MgO-C refractories.For refining slag S3(R=1.2),increased CaO content causes reduced viscosity and elevated surface tension,which enhances slag penetration by 69.14%compared to refining slag S1(R=0.8).However,the structural integrity of refractory is relatively well-preserved.This study demonstrates that moderately increasing refining slag basicity can extend the service life of MgO-C refractories.However,in practical application,it is necessary to comprehensively consider its influence on inclusions in steel.关键词
