Heat-resistant Steel Castings Overview:

Heat-resistant steel refers to alloy steel with high strength and good chemical stability at high temperatures. The development of heat-resistant steel castings is closely related to the technological progress of power plants, boilers, gas turbines, internal combustion engines, aero engines and other industries. As the differences of work temperatures and stresses, and the various operating conditions, so there are different kinds of heat-resistant steel castings. In order to meet the continuous development of various working conditions, heat-resistant steel castings are constantly evolving, from the earliest low carbon steel and low alloy steel, to the high-alloy heat-resistant steel of complex composition and multi-alloyed.

1．Heat-resistant steel castings of cement industry

Heat-resistant steel castings of cement industry mainly include grate plate of grate cooler, grate cooler, preheater inner barrel of cement kiln, hanging plate of preheater, anchor, guard plate of kiln mouth, guard plate of kiln tail, flap valve, valve plate, sealing strip, layer plate, blind pate, feed bucket, dispersion plate, guide rail, strip, lifting hopper, steel ball, tower top, chain, feeding scraper-though conveyor, standard components, etc.

2. Heat-resistant steel castings of heat treatment industry
