500万t链箅机-回转窑球团工艺及装备

Process and equipment of 5million tons grating machine- rotary kiln type pellet plant

钢铁行业是耗能大户,为实现节能减排,设备的大型化已经成为发展的必然趋势。在湛江500万t链箅机-回转窑球团的设计过程中,避免了以往链箅机-回转窑球团厂遇到的一些实际问题,开发的大型造球机提高了效率、降低了单耗,成功实现大型链箅机头尾双传动,应用先进的焙烧监控技术防止结圈,实现球团添加内配煤技术,膨润土拆袋全自动技术,以及耐火材料烘烤等先进技术,为推动大型链箅机-回转窑球团工艺的发展迈出了重要的一步。

The steel industry is large energy consumption, in order to achieve energy conservation and emissions reduction, equipment of large scale has become the inevitable trend of development. In Zhanjiang 5million tons pellets by grating machine - rotary kiln design process, some practical prob- lems in grating machine - rotary kiln pelletizing plant were avoided, the large pelletizer improved the efficiency and reduced consumption, head and tail of grating machine realized double transmission, and the application of advanced roasting monitoring technology prevented the ring. The advanced tech- nologies of adding coal technology, bentonite bag removal automatic and refractory baking advanced were achieved, for promoting the development of grating machine - rotary kiln pelletizing process took an important step.
