Brief Introduction of the material
    NMQJ series gas-block castables consist of gas-blocking compound binding agents, super fine powders and light weight aggregates, showing such features as low thermal conductivity, small linear changes, high strength and no need of baking, etc. They could widely be used various heating furnaces, normal de-compressing furnaces, coking furnaces, reforming furnaces, hydrogen generating furnaces and hydrogen manufacturing transformer furnaces, etc.
