Introduction

Zirconia refractory brick is acid refractory product which is made of ZrO2 and zirconium corundum clinker as material,  the content of ZrO2 is 65%. It is produced by mixing, molding, drying and sintering at high temperature in shuttle kiln.

Features

1: Low thermal expansion / Low calcining expansion/ Low heat expansion/ Low thermal dilatation

2: the thermal conductivity reduces along with the temperature growth

3: Good thermal shock resistance performance

4: Stable chemical characters

5: Excellent abrasion resistance/ abrasion-ability/ wear resistance/ wearability/

6: High performance of alkaline medium erosion resistance

7: the refractoriness under load can be 1700℃

8: Dense crystal structure

9: High bulk density

10: High mechanical strength at normal and high temperature

11: Low creep and low permanent liner change rate. 

Application

Dense zirconia brick is primarily used as the middle brick between silica brick and AZS brick for glass kiln. Zircon refractory brick is also used for arch brick, temperature hole brick, observation hole brick in glass furnace. It is applied for ladle lining brick, stopper brick, nozzle brick, continuous casting used shaping nozzle brick in steel plant.

Company Introduction

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.
