浅谈石灰竖窑技术改造

Brief Talk on Technical Modification of Lime Shaft Kiln

老式机械化石灰竖窑装备落后,其生产出的石灰质量低,已满足不了冶炼优质钢种生产的需求。针对这种情况,马钢股份公司第三钢轧总厂对该种窑进行了技术改造。改造后的石灰竖窑能生产出优质的活性石灰,采用活性石灰炼钢,可缩短冶炼周期,降低吨钢石灰消耗。

The equipment of old type mechanical lime shaft kilns is behindhand, the quality of the lime produced from the kilns is low and it can not meet the production requirement Of various kinds of steel. In accordance with this situation, No.3 Steel Roiling General Plant of Ma＇anshan Iron and Steel Co., Ltd. has modified the old type mechanical lime shaft kilns. The modified lime shaft kilns can produce high quality active lime. The steelmaking with active lime can shorten steelmaking cycle and reduce the lime consumption per ton of steel.
