Application of wear-resistant bricks: mainly used in the parts that need to use wear-resistant and high-temperature materials, such as the slide brick of the metallurgical push steel heating furnace using the steel platform (steel trough) of the stepping heating furnace (steel trough) and the lining of the waste incinerator
Product introduction of wear-resistant brick
Its compact structure, with wear resistance, impact resistance, high temperature resistance, thermal shock resistance and other advantages, mainly used in the need to use wear resistance and high temperature parts, products not only in the domestic steel began to promote the use, and has been exported to South Korea, Indonesia, Taiwan and other countries and regions.
Wear-resistant brick is made of high-quality bauxite and imported Australian zirconium sand and other raw materials, melting at high temperature in the arc furnace, casting completed, mainly used for parts that need to use wear-resistant, high temperature materials, such as the slide brick of the metallurgical push steel heating furnace using the steel platform (steel groove) of the stepping type heating furnace steel platform (steel groove) and waste incinerator lining
