Q:Brick
An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.
Q:The production of brick, the ingredients of why join the waste brick?
Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
Q:The hot blast stove when the temperature did not rise against the brick interface decreased
Insulation of hot blast stove, key insulation silica brick hot stove, hot blast stove is shutdown or need repairing in blast furnace.
Q:What is the silica refractory products?
Refractory brick with silica content greater than 90%.
Q:The United States of our brick anti-dumping duties?
. According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.
Q:Semisilica brick interpretation
Good thermal shock resistance. In use, more high viscosity glass phase can be formed, and the masonry brick joint and the working surface are dense and the masonry is complete, which is beneficial to improve the impermeability of the masonry and reduce the erosion effect of the slag on the masonry.
Q:Glass kiln brick for physical and chemical indicators?
Glass kiln with high quality silica brick with silicon oxide content, low melt index, mainly used for glass kiln crown, parapet, wall hanging, small furnace arch superstructure and regenerator.
Q:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
That is because the brick load softening point the maximum temperature is 1450 degrees.
Q:The formula in the refractory brick, and firing curve, who knows?
By silica powder, 81-85%, perlite 15-19%, plus the total weight of the main raw materials of the following accessories
Q:Why will expand when heated brick
After high temperature after the formation of tridymite and cristobalite and quartz and a small amount of residual glass phase, quartz heating to 220-240 DEG C, in a certain degree of thermal expansion, brick maximum expansion occurs in 100~300 DEG C, 300 expansion before the total amount of expansion is about 70%~75%.
