High Thermal Shock Resistance Magnesia Alumina Spinel Brick for Cement Kiln Application

China refractory factory Low price high Thermal Shock Resistance magnesia alumina spinel brick for cement kiln

The magnesia alumina 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. Magnesia alumina spinel bricks have good properties, such as good corrosion resistance, corrosion resistance, spalling resistance, slag resistance, wear resistance, thermal shock resistance and high temperature resistance. Magnesia alumina spinel bricks are widely used in refractories, steelmaking, cement rotary kilns and glass industrial furnaces.

Magnesia alumina spinel bricks are mainly composed of high-purity magnesia and synthetic magnesia alumina spinel sand, and the main crystal phases are forsterite phase and magnesia alumina spinel phase. Magnesia alumina spinel bricks have high temperature performance, high thermal shock stability, strong resistance to alkaline substances, good wear resistance and resistance to high temperature thermal loads.

The detailed Magnesia Alumina Spinel Brick Data Sheet:

1.The Magnesia alumina spinel bricks Production Process
Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment

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.

The Magnesia Alumina spinel brick Usage:

Magnesia alumina spinel bricks have good properties such as good corrosion resistance, corrosion resistance, spalling resistance, slag resistance, abrasion resistance, thermal shock resistance and high temperature resistance. Magnesia alumina spinel bricks are widely used in refractories, steelmaking, cement rotary kilns and glass industrial furnaces.

Magnesia alumina spinel brick is a kind of magnesia brick with magnesia alumina spinel as the main mineral, which is formed by adding alumina to the ingredients to improve the thermal stability of the magnesia brick. Magnesia alumina spinel bricks have good thermal stability and will react with clinker during use, and then form a thin calcium aluminate protective layer on the surface of the bricks, which makes liquids difficult to penetrate and has good resistance force. The peeling performance is better than that of directly bonded magnesia chrome bricks. Compared with the direct use of magnesia chrome brick combination, the service life of the cooling zone and transition zone in the kiln can be doubled. However, in terms of corrosion resistance, it is worse than the direct combination of magnesia chrome bricks. At the same time, sintered spinel bricks are easy to hydrate, resulting in a larger coefficient, and the temperature of the kiln is higher than when directly bonding magnesia-chrome bricks. Please pay attention to these issues when using them.
