Abstract：The waste heat recovery technology of BF slag was developed by Shandong Jiuyang Group. The technology is consisted of collecting middle pressure saturated steam changed by evaporated cooling water, getting circulating hot air used of wind cooling, again recovered waste heat by waste heat boiler. The recyclable heat quantity of ton of iron is 257.7 MJ, the comprehensive recovery ratio can reach 87%, and the process can save of water consumption 7-9 t every ton of slag compared with the traditional water quenching slag process.
