Product Introduction

Fused rebonded magnesia-chrome bricks are made of fused magnesia-chrome particles as the main raw material, which is formed by high-pressure molding and ultra-high temperature sintering. The product has the characteristics of erosion resistance, and is mainly used for the working lining of the lower tank of the RH furnace and the alloy feeding port.

Features

1.High strength at high temperature. 2.Good volume stability. 3.Good corrosion and erosion resistance. 4.Good thermal shock resistance.

Application

It is suitable for secondary refining VOD furnace, LF furnace, VAD slag line, AOD furnace tuyere area, RH, DH vacuum degassing device, glass melting furnace regenerator, copper smelting converter tuyere area.
