A pre-reaction magnesium-chromium brick (PMC) is a kind of ceramic material frequently used to line the interior walls of industrial furnaces, in order to provide protection against chemical attack, heat transfer and abrasion. PMC bricks are composed of a special blend of magnesium oxide (MgO) mixed with chrome oxide (Cr2O3). The composition of each brick is determined depending on the specific temperature requirements and chemical conditions of the furnace.
PMC bricks offer several major benefits. First, the bricks exhibit excellent heat resistance and can withstand high temperatures. This allows the bricks to be used in higher temperature ranges than ordinary ceramic bricks. Additionally, the bricks contain high levels of corrosion resistance, waterproofing, and wear reheating capability.
PMC bricks can be made in a variety of sizes and shapes. Generally, PMC bricks are extruded or cut to custom fit the customer’s needs. The bricks are also notable for their ability to be cut in complex shapes which make them ideal for lining curved surfaces inside an industrial furnace. As a result, PMC bricks offer superior performance and durability compared to conventional ceramic bricks.
The bricks are also highly durable and can withstand a broad range of chemical attack. Depending on the composition, the bricks can exhibit excellent resisting against oxidation, thermal shock, and alkali and acidic attack. The high level of stability, combined with their superior heat resistance and wear reheating capabilities make PMC bricks ideal for many industrial applications.
When searching for a high-performance ceramic brick for furnace lining, PMC bricks are typically the best choice. The key advantages of these unique bricks—including exceptional heat resistance, excellent wear reheating capabilities and high levels of corrosion protection—make them perfect for many industrial uses. Additionally, the unique shapes and sizes available with PMC bricks make them an ideal choice for custom furnace designs. Moreover, the bricks offer superior protection and durability compared to conventional ceramic bricks.
In conclusion, PMC is an ideal choice for those looking for high-performance ceramic bricks for furnace lining. The superior temperature and corrosion resistance offered by these bricks make them perfect for many industrial applications. Additionally, the variety of shapes and sizes available with PMC bricks also make them a perfect choice for custom furnace designs.
