It is widely used in the lining of the kiln working face which is in direct contact with the flame, and has become one of the research hotspots in recent years.
Insulating fire brick is a new type of building material synthesized with polymer materials. The main function is to keep warm, reduce heat loss and improve thermal efficiency.
Brown corundum is made of natural bauxite as raw material, carbon (mainly coke) is used as reducing agent, and iron filings are added as sedimentation agent (clarifier) to form ferrosilicon deposited on the bottom of electric furnace.
Fireclay bricks are classified as weak acid refractories. Due to the large fluctuation range of chemical composition, different production methods, and differences in firing temperature, the properties of clay bricks change greatly.We can produce all kinds of Fireclay bricks according to customers' requirements
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
Refractory carstables for ladles is made of high-purity fused corundum as the main material, high-purity spinel is added to the matrix, and an appropriate amount of binder and admixture (dispersant, water reducing agent) are added.
High alumina brick is mainly used for lining of blast furnace, hot blast furnace, electric furnace roof, reverberatory furnace and rotary kiln. In addition, high alumina brick also widely used as open hearth regenerative lattice brick, pouring system with plug,such as nozzle brick.
The refractoriness of clay bricks is comparable to that of silica bricks, up to 1690~1730℃, but the softening temperature under load is more than 200℃ lower than that of silica bricks. Because in addition to the high refractory mullite crystal, the clay brick also contains nearly half of the low melting point amorphous glass phase.
Refractory wet mud used to block the iron outlet can be divided into two categories: water cannon mud and waterless gun mud. On large and medium -sized blast furnaces on high top pressure and high degree of smelting.
