酒泉钢铁公司1号高炉(1513m~3)于1970年9月投产,1984年10月停炉大修(其间中修一次)。在停炉过程中,由于采取了一些有效措施,残铁出得比较顺利,整个炉底上找不到一块一公斤以上大的残铁块,达到了“出净、安全、快速”的要求。1.情况简介(1) 测算炉底侵蚀深度炉底为带有风冷管(实际很少使用)的炭砖、粘土砖综合炉底,总厚4015mm。根据兰姆公式计算得出炉底侵蚀深度为1.19m。实际炉底侵蚀平均深度为1.1m,中间侵蚀深0.8m呈平坦形;周围侵蚀呈一圈环形沟,宽1m左右,深1.145米;整个炉底形状呈反扣盘子形。
Jiuquan Iron and Steel Company No. 1 blast furnace (1513m ~ 3) put into operation in September 1970, October 1984 shutdown overhaul (during the repair time). During the process of shutdown, due to some effective measures, the residual iron was smoother and the whole furnace bottom could not find a piece of large iron residue one kilogram or more, which met the requirements of “making the net, safe and fast.” 1. Brief Introduction (1) Calculating the depth of bottom erosion The bottom of the furnace is carbon brick with air-cooled pipe (actually rarely used). The total thickness of clay brick is 4015mm. According to Lamb formula, the depth of bottom erosion is 1.19m. The actual depth of the bottom of the erosion of the average depth of 1.1m, the middle depth of 0.8m was flat-shaped erosion; the surrounding erosion was a ring of annular groove width of about 1m, 1.145 meters deep;
