How Much Does High-temperature Refractory Brick Cost Per Ton?

Our Blog
High-temperature refractory brick refers to a type of refractory material that can withstand high temperatures without being damaged. It is commonly known as firebrick and is widely used as the lining material in high-temperature industrial kilns and furnaces. High-temperature refractory bricks are made by mixing refractory raw materials into a clayey mixture, filling the mixture into molds, and then high-pressure molding with a friction brick press. After drying and removing a portion of the free water, the bricks are fired…

Expansion of Corundum Mullite Bricks in the Refractory Industry

Expansion of Corundum Mullite Bricks in the Refractory Industry

Our Blog
Corundum mullite bricks, known for their exceptional properties and composition of corundum and mullite, are widely recognized as high-alumina refractory bricks. These bricks are fabricated from high-purity or relatively pure raw materials, ensuring their remarkable heat resistance and durability. However, it is crucial to address the impact of low-melting-point oxide impurities on their high-temperature performance. Notably, corundum mullite bricks are more expensive compared to ordinary high-alumina bricks due to their superior physical and chemical characteristics. The distinguishing features of corundum…

Introduction of Refractories for Soaking Furnace Lining and Thermal Operation

Our Blog
Reheating furnace is also one of the heat treatment furnaces in the rolling mill. It consists of furnace cover, furnace wall, furnace bottom and heat exchanger. Its function is to heat the steel ingot uniformly to the rolling temperature, so that the rolling mill can roll the steel ingot into large, medium and small billets, and then roll into various steel materials. If it is a continuous casting billet, it can be directly rolled into various steel materials without reheating…

Alkali-Resistant Bricks for Cement Kilns

Alkali-Resistant Bricks for Cement Kilns

Our Blog
Alkali-resistant bricks for cement kilns refer to clay refractory bricks that are primarily made from low-alumina refractory clay and possess alkali erosion resistance in cement kiln systems. The main raw materials for alkali-resistant bricks include mullite, pyrophyllite, and silica. The alkali resistance mechanism of these bricks involves reacting with alkali metal oxides at high temperatures to generate a high-viscosity liquid phase, which forms a glaze protective layer. This layer covers the brick surface and blocks surface pores, preventing the penetration…
