High Cr Heat Resistant Grate Bar for Sintering Machine
The stainless steel grate produced by our company adopts vacuum vibration magnetic casting technology, which solves the problems of grate hole, shrinkage, slag inclusion, non-compacting, and other casting defects, and increases the density of the body, the density of the original 7.4 increased to 7.85, due to the increase in the density of the body, improve the service life.
The high temperature resistant grate in the ironmaking plant has a particularly high requirement for heat resistance. It must withstand a high temperature of about 1000℃ and have a certain high temperature strength.This company sintering grate material is ordinary gray cast iron, short service life, large consumption, poor heat resistance, sintering machine shut down frequently, the labor intensity of workers is very high productivity is also low.
Inclined reciprocating grate is different from chain grate one of the main characteristics, to draw customized high chromium grate, grate and coal have relative movement.When the active grate pushes back and down, some of the new coal is pushed to the upper part of the burned coal. When the active grate returns to the upper part, it brings back some of the burned coal to the bottom of the unburned coal and heats the new coal.This kind of ignition condition is similar to hand burning furnace and superior to chain furnace.In the process of being pushed, the coal is continuously squeezed, thus destroying the coke and ash shell.At the same time, the coal is rolling slowly, making the coal seam loose and smooth, which is conducive to combustion.
