山东九羊集团有限公司开发了高炉炉渣余热回收技术，将绝大部分冷却水蒸发为中压饱和蒸汽进行收集，然后采用风冷工艺获得热循环空气，通过余热锅炉再次回收余热，吨铁可回收热量257.7 MJ，综合回收率可达87%，与传统的水淬工艺相比吨渣可节约用水7~9t。
山東九羊集糰有限公司開髮瞭高爐爐渣餘熱迴收技術，將絕大部分冷卻水蒸髮為中壓飽和蒸汽進行收集，然後採用風冷工藝穫得熱循環空氣，通過餘熱鍋爐再次迴收餘熱，噸鐵可迴收熱量257.7 MJ，綜閤迴收率可達87%，與傳統的水淬工藝相比噸渣可節約用水7~9t。

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.
