Introduction

High purity corundum refractory brick is made of imported tabular corundum and high purity fused corundum as raw material. the Al2O3 content≥ 99%, and the main crystalline phase is corundum.

Features

1: High refractoriness under load temperature with 1700℃

2: Stable chemical performance

3: Good corrosion and slag resistance

4: Good performance of anti-stripping

Application

Primarily used for side wall and smelting bottom in glass furnace.

Dengfeng Heverye New Refractory always committed to manufacturing high-grade refractory products for glass industry. Our production manager own 15 years comprehensive experience of management in refractory industry, who has a good knowledge of how to ensure products quality via controlling whole production steps, from raw material, mould production to sintering bricks.

Removing the iron two or three times is to ensure purity of raw material, which can control the quality in the foremost production step. Heverye adopts advanced mechanical transport pathway which can decrease the damage of unfinished bricks, meanwhile can save the cost. Heverye people persist on producing each product by our craftsmanship, the FQA can be 100%.

Our mainly new type chrome zircon mullite brick is characterized with anti alkali resistance, anti spall resistance and anti explosion resistance, it is particularly used in regenerator part, port neck and fuel inlet part. the glass furnace can be increased 3-5 years working life. Our products have been certified by CNAS, we are pleased to accept the certification from our client's requirements.
