Refractories Co., Ltd., Zhengzhou City shangzhuang feel important factor refractory structure also affect macroeconomic performance refractories prices, and performance indicators can reflect the internal structure of refractories. For example: that the nature of the extent of a compact porosity, trifoliate body density, true density; indicate the nature of the gas through the degree of difficulty. Porosity: Indicates the thermal properties of the nature of the first-line expansion coefficient, thermal conductivity, heat capacity and thermal conductivity; indicate the nature of the mechanical properties - at room temperature and high compressive strength, high-temperature pit fold strength, high temperature torsional strength, creep resistance, Gao Wen and elastic modulus; represents high-temperature performance of a - refractoriness, high temperature load softening temperature, Gao Wen volume stability, thermal shock resistance and slag resistance. So refractories, using department must proceed from the thermal characteristics for the Treasury and process requirements refractories sales, according to the chemical composition of refractory mineral and 撖 concept structure, microstructure and properties of macro indicators carefully selected to achieve the desired effect of the use . Reliable processing trends Refractories Co., Ltd., Zhengzhou City shangzhuang talk about the remaining refractory materials: For the steel industry, which includes the recycling of waste, including the driver of a variety of waste refractory oxides are: to further improve air and water emissions indicators, reduce waste, reduce dependence on increasingly scarce and expensive to improve filling space and improving energy efficiency. Many factors are causing concern for the recycling of waste refractories this issue. Which is good _ shangzhuang refractories Refractories (certified) _ Shenzhen refractory provided by Zhengzhou City shangzhuang Refractories Limited. Zhengzhou City shangzhuang Refractories Co.
