Grate Plate / grate cooler for chain grate machine by Cr25Ni20 material. The grate plate is an important part of the chain grate. The quality of the product directly affects the use effect of the chain grate. The grate machine is widely used in metallurgy and other industries, and plays a vital role in the operation of the entire plant. Therefore, we attach great importance to the quality of grate board and pursue excellence.

We use heat-resistant steel material to produce grate board, the product has good heat resistance, and adopts advanced casting process to ensure product size accuracy meets customer requirements. We strictly control the chemical composition of the products and pursue the best heat resistance. Our products have been widely praised by customers.

Material requirement as follow:

We are supplying many different kind of heat resistant steel castings to our customers and we use both investment casting process and sand casting process for different size or different structure casting. For suitable castings, we also choose lost foam process which have better cost and quality performance.

There have lot of different specifications for such castings, usually we produce according to customers drawings and specific requirement, following are the common materials which we usually supply: ZG35Cr24Ni7SiNRe, ZG40Cr25Ni20Si2, 1Cr18Ni9, ZGCr25Ni35Nb, ZGCr28Ni48W5 HK40, HT, HU, HH, 22H, 304, super 22H, HP-Nb, More1, More2, 1.4848, 1.4855, 1.4852, 2.4879, 1.4460, 1.4462, S32205, S32750, etc.

Our products are been widely use in cement plants, electric generate plant, melting industry, and other industries. In recent years, there are more and more professional municipal waste incineration stations, and we have developed a lot of heat-resistant casting products specially supplied to such factories.
