Detailed introduction:

电炉镁碳砖价格


电炉镁碳砖(magnesia-carbon brick for electric furnace)是指以镁砂和石墨为原料制成的用于电炉的耐火制品。镁碳砖从1970年工业生产以后约10a间,都用于电炉炉壁。由于这种砖具有高耐火性,高耐侵蚀性,优良的耐热剥落性和高温体积稳定性,高的抗热震性等特性,较快地得到推广应用

电炉用镁碳砖与转炉用镁碳砖最显著的不同是含固定碳范围不同。前者为10%-30%,后者为10%-20%。因此,在电炉镁碳砖生产中要多配入鳞片状石墨。其他生产工艺环节与转炉镁碳砖相同

用作电炉炉壁衬砖,特别是高功率和超高功率水冷电炉炉壁热点和渣线等电炉炉壁蚀损严重部位。在超高功率大到电炉水冷炉壁使用镁碳砖。寿命可达300次以上。电炉炉底也开始使用镁碳砖
