Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?: Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.

Q: In 2016, a few of the traditional refractory materials will be able to survive: From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;

Q: How much is one ton of high alumina refractory brick?: High alumina refractory brick according to the different content of AL2O3 is divided into grade, grade one and grade two, and grade three high aluminum brick, Zhengzhou Kang Hui refractories factory price in 800-1900 yuan / ton, stable quality, are exported to the domestic and foreign markets.

Q: What is the price of the latest thermal insulation material?: Also through online pre understand the products and prices, and now have large-scale manufacturers are generally opened on the cable business. Goods than three, manufacturers on-site inspection, confirm the quality of goods after considering cooperation.

Q: How many cubic bricks does a high alumina brick have?: Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.

Q: What are the characteristics of high alumina bricks?: The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.

Q: How does the physicochemical index change when the high alumina brick is used at high temperature?: If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.

Q: What is the high temperature limit of refractory bricks and refractory soil?: Fire clay -- usually refers to folk point stove furnace set with a kind of soil, limit under atmospheric pressure of 1500 degrees fire clay soil 1, properties and uses: clay brick of weak acid refractory material, its thermal stability is good, suitable for hot blast furnace, boiler and flue, smoke chamber lining, etc..2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

Q: What is the difference between fireclay bricks and high alumina refractory bricks?: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3.

Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?: The gas will directly lead the dome combustion, in order to ensure good mixing, complete combustion of gas and air in a short time, the combustion capacity of short flame or flameless combustion burner, commonly used for semi jet short flame burner.
