The Structural Analysis and Optimization of DN750 Material Control Gate
The top charging device has experienced the development process from bell-type top to bell-less top,The bell-less top can accurately distribute the material surface shape to meet the production requirements of the blast furnace.The material control gate is the only means to accurately adjust the distribution speed of bell-less top furnace,Its opening value and opening shape di-rectly affect the rationality and uniformity of blast furnace distribution.The structural characteristics,working principle and transmission mechanism of the material control gate are analyzed and studied,the trajectory equation of internal and external valve plate and the key points of design are obtained.And optimize the transmission mechanism.A theoretical calculation basis for the optimization of the disc drive mechanism of a feed flow valve is given.This paper provides a design idea for the design and se-lection of top charge flow regulating valve of bell-less top.
