Magnesia Alumina Spinel Brick

Magnesia Alumina Spinel Brick is a specialized refractory material formulated by combining magnesia and alumina to create spinel, a compound known for its outstanding thermal and chemical properties.The magnesite spinel bricks are made of high-quality alumina with an Al2O3 content of 76% or higher and high-quality light-burned magnesia powder with a MgO content of more than 95%. After multi-stage homogenization, the temperature of the ultra-high temperature tunnel kiln is higher than 1800°C.

Exceptional Thermal Stability: Magnesia alumina Spinel Brick demonstrates exceptional resistance to high temperatures prevalent in steelmaking, cement production, and other high-heat industrial processes.
Excellent Corrosion Resistance: The spinel phase offers remarkable resistance to chemical erosion and slag attack, making it suitable for harsh environments with corrosive elements.
Structural Integrity: These bricks maintain stability under thermal stress, providing prolonged service life and reducing maintenance costs in high-temperature applications.

Magnesium sand and fused magnesia alumina spinel sand are crushed and crushed according to the process, so that the aggregate particle composition and fine powder fineness meet the process requirements. The prepared aggregate and fine powder are strictly weighed according to the process requirements, and added A certain amount of binder; mixed in a mill mixer for 15-20 minutes, formed on a friction brick press, and dried for 8-16 hours; the dried bricks are fired in a tunnel kiln with a maximum firing temperature of 1660-1800C.

The quality assurance system of Magnesia alumina spinel brick consists of the following steps:
1. 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.
2. Inspection and process control:During the production, each brick weight twice to reduce weight error.
3. Inspection of product Standardization of quality of each product by process control and experimentation.
4. Taking corrective measures whenever deviations are noted.
