Product Details

Shandong Furnace Refractory Bricks

Product Description

The refractory bricks are dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory bricks are the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

The refractory bricks have wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Linquan series alumina bricks are high quality dry pressed alumina bricks, ranging from 35% to 95% in alumina content.
