Steel plant molten iron from the blast furnace mouth torpedo, which was then transported to or through torpedo ladle of molten steel mill Mixer. Homogenized molten iron into the ladle from Mixer Hebei nano-porous insulating material, and then enter the BOF. Qualified molten steel from the converter and then tapping into the ladle, transported to the start casting the caster. Transported over long distances and wait Shanxi nano-porous insulating material, so that the molten steel or molten steel cooling rate of the whole process has become an important indicator, in order to ensure the continuous casting of molten steel before the process temperature reaches a predetermined temperature, the need to speed the molten steel temperature drop determine an appropriate superheat. Selection of microporous insulation material and cooling rate of the molten steel can be minimized, thereby reducing the superheat, energy conservation, accelerate the melting cycle Heilongjiang nano-porous insulation materials, increase steel production, to improve slab quality. Tianjin Gute energy saving Technology Co., Ltd. developed the production of nano-porous insulation board for insulation of equipment, especially in all kinds of industrial production with outstanding contributions, industrial production equipment using nanotechnology microporous insulation material can significantly reduce carbon dioxide emissions, improve the environment of nano-porous insulation materials, create green homes. The country can produce about four or five of the Hai heat, can Hui Guangzhou, Tianjin solid Principal, product performance and stability among the strongest Tianjin Goodrich energy, thermal conductivity compared with other manufacturers are also relatively low, heat insulation effect is the most obvious, Tianjin Goodrich saving nano microporous insulation board as many customers to solve technical problems.
