Yangquan quality blast furnace factory direct, high alumina brick kiln with a variety of fire-resistant fire prevention materials

Introduction The company produced high-alumina refractory brick have high refractoriness, high load softening temperature, good thermal shock resistance, acid, alkali resistance, spalling, corrosion resistance, high temperature creep rate, high temperature strength. Uses: mainly used for furnace roof, furnace, stove, ladle, ladle, hot metal cars, cement kilns, glass kilns and other thermal furnace lining. Widely used in iron, steel, chemicals, cement and other industries. Ordinary high-alumina refractory brick divided by physical and chemical indicators (national standard): LZ-48, LZ-55, LZ-65, LZ-75, LZ-80 (refractoriness 1750 ℃ ??-1820 ℃).. Alumina bricks with an aqueous aluminum oxide mineral (a boehmite, gibbsite, etc.) as the main component of bauxite; sillimanite group minerals (including kyanite, andalusite, sillimanite, etc.); artificial synthetic materials, such as industrial alumina, mullite, fused corundum. China high aluminum vanadium soil rich resources, fine texture, origin mainly located in Shanxi, Henan, Hebei, Guizhou, Shandong and other places. Produced by high alumina bauxite, mainly a boehmite (α-Al2O3 · H2O) and a mixture of kaolinite two minerals. \ N bauxite rotary kiln or shaft kiln calcination, sintering temperature 1500 ~ 1700 ℃. Well-sintered bauxite, water absorption generally 4 to 7 percent of physical and chemical indicators of high-alumina refractory brick item (Item) Index (Index) LZ-48 LZ-55 LZ-65 LZ-75 LZ-80 AL2O3,% ≥ 48 55 657,580 Refractoriness, ℃ ≥ Refractoriness 1750 1770 1790 1790 1820 0.2Mpa load softening start temperature, ° C≥ Refractoriness under load, 0.2MPa, 1420 1450 1500 1520 1530 on heating,% Permanent linear Change 1500 ℃, 2h 0.1-0.4 1450 ℃, 2h 0.1-0.4 apparent porosity,% ≤ Apparent porosity 22 22 23 23 22 Cold crushing strength, Mpa≥ Cold crushing strength 35 40 45 50 55 blast furnaces with high alumina refractory bricks according to performance indicators divided into: GL-48, GL-55, GL-65.

About us refractories plant Yangquan positive element located in the famous township refractory materials - Yangquan, Shanxi. Local rich bauxite and coal, is China's largest production base of refractories in China enjoy a high reputation abroad. Zhengyuan refractories plant was built in 1995, 10 million yuan in fixed assets, more than 100 employees, including five senior engineer. Advanced equipment and technology, and improve the service so that enterprises in the industry counterparts enjoyed a high reputation. A company's existing tunnel kiln with natural gas firing process, the annual output of 15,000 tons has been assessed relevant units of energy-saving model enterprise. The main products are high alumina bricks, clay and other specifications of various monolithic refractories and castable, ramming mixes, heat feeding, aggregates, powder and other unshaped refractories. Provide supporting materials for the metallurgy, building materials, electricity, chemicals and other industrial furnaces, mainly for masonry blast furnace, hot stove, electric stove top, blast furnace, reflection furnace, rotary kiln lining, companies selling products all over the country and exported to Japan, Korea, Southeast Asia and other countries, product quality stability and quality of service, won the praise of users. I companies adhere to honesty, quality products, perfect service, cross-world friends.
