High Alloy Heat-resistant Castings
Highly alloy heat and abrasion resistant castings can effectively resist heat, wear and oxidation in different temperature ranges within 600~1300℃.
The main products include spraying nozzles of boilers, grate barsfor sintering, grate plates for clinker cooling machines, furnace bed platesand teeth for slag crushers.
