Heating furnaces in steel plants, heat exchange equipment in the metallurgical industry, filters for molten metal, and catalyst carriers in the chemical industry.
Detailed Introduction
Usage: Heating furnace for steel plants, heat exchange equipment for metallurgical industry, filter for molten metal, catalyst carrier for chemical industry.
Features: There are two types of pore structures, square and regular hexagonal, with parallel straight channels that can reduce the resistance of pore flow. It has the characteristics of large specific surface area, reduced pressure, low resistance, high temperature resistance, good chemical stability, low thermal expansion, good insulation, light weight, and high strength.
