Detailed Product Description
Firestopping brick mainly protects heat media and saves thermal storage medias using time. Firstly, we should consider resistance to elevated temperature and thermal shock performance; at present, it mainly adopts high alumina vanadine as raw materials, which decrease partial industrial alumina for producing firestopping brick; due to worse high temperature resistance and oxidation resistance of sheet iron rusty, it could not assure thermal storage medias good performance.
Now, we developed firestopping brick with corundum materials, which contains good performance for high temperature resistance and thermal shock resistance; the corundum bricks service time is higher than high alumina brick, also insures honeycomb ceramics using time, which reduce furnace outage time and production cost.
Our brick is mainly used for furnace brick lining of ceramic, steelworks, building, metallurgy and chemical
