The invention relates to a mosaic type furnace bottom block. As a common heating furnace adopts a guide-rail type furnace bottom, specially-produced heat resistant steel is needed for manufacturing and manufacturing cost is high. According to the invention, polycrystalline mullite, calcium aluminate, alumina fibre and emery powder are mixed to prepare a solidified block, and the blocks are spliced to obtain a heating furnace bottom plate. The block provided by the invention is prepared from inorganic composite materials. The block is resistant to high temperature and high-temperature strength of the block is far higher than high-temperature strength of steel. By using the block to prepare a furnace bottom plate in a high-temperature area of a heating furnace, a guide rail in this area is omitted, and hot billets directly slide forward on the furnace bottom plate. The block provided by the invention has advantages of high-temperature resistance, high strength and long service life.
