AS2074 L5C Heat Resistant Steels Grate Bars High Wear & High Temperature Steel Incinerator Grate Bar Parts
Product Description:
Mechanical Grate Incinerators can be divided into horizontal reciprocating grate system, inclining grate system from the layout of grates. Or they can be divided into three types from the moving ways: Push type reciprocating grate system,Inverse push type reciprocating grate system and Rolling type reciprocating grate system.
The grate system can be composed of moving grate bars and fixing grate bars. The structure and shape of the two grate bars are designed to be same so that it is very convenient for replacement. The width of grate system will be decided by handling capacity of waste. When calorific value is designed to be 6270kJ/kg, the surface temperature of grate bars is 400~500 centi-degree, the service life of grate bars can be about 5 years.
The key element for incinerators is grate bars. The chemical composition is as follows:
