Competitive price Long Life Sintered Zircon Corundum Brick For Glass Kiln
The raw materials of sintered zircon corundum bricks (hereinafter referred to as sinteredAZS bricks) are alumina and zircon. Generally speaking, the content of ZrO 2 is controlled at 15%-30%. The main crystal phases are mullite, corundum and zircon. In very pure raw materials, the glassy phase content can be less than 5%.
Sintered zircon corundum brick advantages:
1: High refractoriness
Sintered AZS bricks have high refractoriness, reaching above 1790°C, and belong to high-grade refractory materials.
2: High softening temperature under load
Sintered AZS bricks have less impurities, and the softening temperature of aluminum zirconium products is generally above 1550-1650 degrees.
3: Good thermal shock resistance
Has excellent thermal shock resistance
4 Chemical resistance
Aluminium-zirconium refractory products have good resistance to acid or alkaline slag, corrosion of molten metal, and oxidation and reduction reactions, and are enhanced with the increase of AL203 content and the reduction of harmful impurity content.

1. Zircon Corundum Brick Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment
2.Zircon Corundum Brick Quality Assurance
HongTai Refractory is committed to high quality standards for all its products and services. With its thirst on State of the art technology at every level and a wide range of products, HongTai Refractory can provide ideal solutions for the stringent requirement of the customer. Backed by decade of experience in different industries, and close association with customers,HongTai Refractory will always bring new products which will give better life and value to the user.
The quality assurance system consists of the following steps:
a.Inspection and Control of incoming raw materials:According to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
b.Inspection and control of the process:During the production,every brick will be weighed twice strictly to reduce the error of weight.
c.Inspection of product Standardization of quality of each product by process control and experimentation.
d.Taking corrective measures whenever deviations are noted.
e.Quality audit by quality management.Before delivery, the inspectors will inspect the size,appearance,physical and chemical properties of Corundum Mullite Bricks again in factory.
Zircon corundum application:
This kind of brick has good high temperature performance, but has a certain porosity, so it is mainly used in the upper space of the glass kiln that is not in contact with the glass liquid, and the sliding rail of the rolling steel heating furnace, etc.
