摘要/Abstract

摘要： 目前浇注钙处理钢用的铝碳和铝锆碳滑板存在着马蹄形侵蚀和关不住等问题。具体分析了浇注过程中钙处理钢对铝锆碳滑板的损毁机理。以电熔镁砂、镁铝尖晶石、刚玉等为主要原材料，经过烧成、油浸、焙烘等工序，成功开发了铝镁碳滑板，同时优化了滑板孔径，有效改善了滑板的抗侵蚀性，使用次数明显增加。

Abstract:

Horseshoe-shape erosion and poor tightness would occur when casting the Al2O3-C and Al2O3-ZrO2-C sliding plate for steel calcium treatment.Mechanism of damage to the Al2O3-ZrO2-C sliding plate by the calcium treatment steel during casting is analyzed in details.Al2O3-MgO-C sliding plate is developed through burning,oil immersion,and drying,which is mainly made from fused magnesia,Al2O3-MgO spinel and corundum,etc.as raw material.The diameter of the sliding plate hole is also optimized.As a result,erosion resistance of the sliding plate is effectively improved,which can be used much more times.

Key words: Calcium treated steel, Horseshoe-shape erosion, Al2O3-MgO-C sliding plate, Al2O3-ZrO2-C sliding plate
