The originally designed iron influx for main channel before 4 150 m3 blast furnace of Baotou Steel is about 0.16 million tons. In the use process, it is found that only the refractory in jet impingement zone is eroded so seriously that cannot be used anymore, while the refractory in other parts of main channel keeps basically intact. If the main channel is disassembled, the cost of pig iron will be greatly increased. The iron influx of main channel could be up to 0.22 million tons through partial spraying with improving the spraying material, particle size and binder so that the cost of molten iron is decreased effectively.
