连铸浇注区域除尘实施方法的分析探讨

随着钢铁行业超低排放要求的落实,连铸浇注区域实施除尘正逐渐成为连铸机的必备配置。在增加除尘设施时,如何将新增设备对现有工艺操作的影响降至最低,同时又对浇注设备及平台结构改造最少,是实施浇注区除尘成功的关键所在。对目前国内连铸浇注区域除尘实施的3种典型方式进行了介绍,并结合作者的设计实践,对每种除尘方式的集尘罩结构特点、对工艺操作及设备的影响、平台改造量等方面进行了分析比较,为连铸浇注区除尘实施方式的选择提供了参考。

Discussion on dedusting method in casting area of continuous caster

With the implementation of ultra-low emission requirements in the iron and steel industry,dedusting in the casting area is gradually becoming a necessary configuration of continuous casting machine.When adding dedusting facilities in the casting area,it is the key to the successful implementation dust removal in casting area to minimize the influence of new equipment on existing process operation and minimize modification of casting equipment and platform structure.Combined with the design practice,this paper introduces three typical methods of dust removal in casting area of domestic continuous casting production at present,and analyzes and compares the structure characteristics of dust collecting hood,the influence on process operation and equipment,and the amount of platform modification.It provides a reference for the choice of dust removal method in casting area of continuous casting production.
