宝钢1号高炉投产后,于1986年10月10日和11月11日分别在高炉34层水箱和19层水箱处,开了2个孔,测定炉墙被浸蚀情况。取出一根圆棒形耐火砖芯(见图1),取芯效果非常好。炉墙得到一个规整的直通炉内的小涵洞。圆棒芯可量得被浸蚀的程度,同时也能检验出炉墙内壁的化学成份的变化和岩相 Baosteel Blast No. 1 blast furnace put into operation, on October 10, 1986 and November 11, respectively, in the blast furnace 34 layers of water tanks and 19 layers of water tanks, opened two holes, was measured furnace wall erosion. Remove a round bar-shaped refractory brick core (see Figure 1), the coring effect is very good. The furnace wall gets a regular, small culvert in the furnace. The extent of the round rod core can be eroded, as well as the variation of the chemical composition of the inner wall of the furnace wall and the lithofacies
