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…
