Product details
describe
Magnesium aluminum brick is mainly made of magnesium sand as the main raw material, with magnesium sand and aluminum oxide (mainly bauxite) added as the grinding fine powder as the matrix, and fired at high temperature of 1580-1620 ℃. Magnesium aluminum brick has improved its thermal shock resistance and high-temperature mechanical strength on the basis of magnesium brick, in order to meet the needs of strengthened smelting.
Characteristics of magnesium aluminum brick:
On the basis of the performance of magnesia brick, it has good slag resistance, improved thermal shock resistance, high temperature mechanical strength, and increased load softening temperature.
Application fields of magnesia carbon brick:
Mainly suitable for high-temperature furnace tops such as steelmaking open hearth and reverberatory furnaces, permanent lining of steel ladles and steelmaking furnaces, glass kiln heat storage rooms, mixed iron furnaces, copper smelting reverberatory kiln roofs, and other industrial high-temperature kilns.
Support customized magnesium aluminum bricks of various brick types, and can be customized and processed according to drawings.

Application of magnesium aluminum brick products
The magnesium aluminum bricks produced by Korei Refractory are mainly used for high-temperature furnace tops such as steelmaking open hearth furnaces and reverberatory furnaces, permanent linings for steel ladles and steelmaking furnaces, glass kiln heat storage rooms, mixed iron furnaces, copper smelting reverberatory kiln roofs, and other industrial high-temperature kilns. Korui adjusts the performance of products in the production environment for different parts and temperature requirements of kilns in the steel and glass industries; At the same time, practical special-shaped brick masonry is used in complex areas, taking into account both the economic benefits of the enterprise and the maintenance needs in the later stage.
In the construction of magnesium aluminum brick masonry, Korei refractory materials will also provide targeted construction suggestions according to the actual situation. At the same time, our supporting construction team can provide you with an overall construction plan. At present, the refractory bricks produced by Kerui Refractory Materials have been successfully applied in many large enterprises such as Shandong Nanshan Aluminum Industry, Henan Shenhuo Coal and Electricity Co., Ltd., and Jinan Aohai Carbon, and have received good market feedback.
