Introduction

High strength wear resistant casting material

First, characteristics and uses:

The wear resistant cast material of the series has the characteristics of high thermal strength and wear resistance, good resistance to erosion and good high temperature stability. Can meet the long cycle of boiler operation. Plastic has good plasticity, easy construction, high temperature stability, wear resistance, etc.. The series product can be widely used in combustion chamber of a circulating fluidized bed boiler in thermal power industry, top, bottom, back to the combustion zone, Ling water wall tube, balanced flue, cyclone separator and heating furnace masonry.
