RH炉浸渍管用镁铬砖的损毁行为分析
Analyzing the Wear Behavior of Magnesia Chromite Brick (MKB)Used in RH Snorkel
摘要
Abstract
Used MKB in RH Snorkel of WISCO was analyzed by means of ICP-AES, XRD, optical microscope,SEM and mercury porosimetry ,and the aim is to clarify the wear behavior of MKB. The results show that adhering slag and cracks are found in the used MKB. The penetration and corrosion layer are mainly constituted by low-melting point cacoclasite and iron as well as its oxides. There is a dense layer with 40μm thickness formed between the penetration and corrosion layer and initial MKB, which mainly consists of FeO and MgO-Al2O3 spinel. The wear behavior of MKB includes two stages. Firstly, molten slag and steel can easily penetrate the open pores of MKB due to its high apparent porosity and large pore diameter,and then the penetrated slag and steel accelerate the erosion and peeling off of MKB. Thus, improving the porous characteristics will be an important route to decrease or inhibit the wear of MKB.关键词
