Long Life Refractory Lining
For large blast furnaces, Al2O3-SiC-C low-cement castables are used as the main trench working lining. Although the service life is continuously improved, due to the high pressure in the furnace,…
Read moreThe difference between graphite electrodes and carbon rods is that the former is mainly made of graphite and the latter is made of carbon. The graphite electrode is a mixture…
Read moreAlthough the baking-free ramming mass used in the iron hooks can meet the construction requirements of the small and medium-sized blast furnace, it can not make the iron hooks reach…
Read moreThe bull rally in prices of graphite electrode set to continue in 2019 and might even hit new highs. According to industry experts, increases in graphite electrode (contract) prices in…
Read moreGenerally, the iron hook castables are usually made of low cement or resin. With pure calcium aluminate cement, the castable has a high initial strength and is easy to form;…
Read moreShortages last year of the Ultra High Power Graphite Electrodes used by EAF-based steelmakers and some non-ferrous metal producers rapidly pushed up their prices. Because the market for steel was…
Read moreFurnace age is a comprehensive technical and economic indicator in converter steelmaking. Increasing the furnace age can not only reduce the consumption of refractory materials, increase the operating rate, reduce…
Read moreThe silica insulating refractory brick is made of finely pulverized silica, and a part of waste silicon brick or waste silicon heat-insulating refractory brick powder, a mineralizer and a burn-in…
Read moreThe problem of alkali corrosion in the blast furnace lining is caused by the damage of the blast furnace. Due to the evaporation, infiltration and agglomeration of alkali metals, many…
Read moreSilica insulating refractory brick refers to an insulating refractory product made of silica as the main raw material and having a SiO2 content of not less than 91%. In addition…
