Shanxi alumina bricks, bricks, GB, Yangquan Zhengyuan refractories manufacturers

 Alumina bricks, the main component of aluminum oxide (Al2O3), its Al2O3 content higher than 48% of aluminosilicate refractory products, if the Al2O3 content of> 90%, called corundum brick. However, due to various countries in different regions of resources, so the standard is not the same countries, such as the European countries to high alumina refractory requirements Al2O3 is more than 42%, while China is more than 48%, in China, in accordance with the aluminum-containing alumina brick amount, namely Al2O3 is usually divided into three different levels. Ⅰ et ──Al2O3 content> 75%; Ⅱ et ──Al2O3 content of 60 ~ 75%; Ⅲ et ──Al2O3 content of 48 to 60%. As for the shape alumina bricks, in addition to the standard high alumina brick, in line with the provisions of GB / T2992, as well as general-purpose high alumina brick, also known as shaped alumina brick, if the shape is very irregular, then usually called the specific type of high alumina bricks, In short, according to the specific use of the kiln to custom, that is produced according to drawings. Alumina bricks classified according to their physical and chemical indicators divided into ordinary aluminum bricks (LZ) and low creep high alumina brick (DRL) alumina brick Features: a, refractoriness refractoriness than alumina brick clay and semi-silica brick refractoriness to be higher, up to 1750 ~ 1790 ℃, belonging to high-grade refractory. b, load softening temperature because of high aluminum products high Al2O3, less impurities, less formation of fusible vitreous, so load softening temperature higher than the clay, but mullite crystallization not forming a network organization it still does not load softening temperature silica brick high. C, slag resistance of Al2O3 alumina brick more close to neutral refractory, resistant to corrosion of acid and alkaline slag slag, because it contains SiO2, so resistance to basic slag weaker than the capacity of the acid resistance of slag more. Alumina brick is mainly used for masonry blast, stove, electric stove top, blast furnace, reflection furnace, rotary kiln lining. In addition, high alumina brick is also widely used open hearth regenerative checker bricks, pouring system with plug head, nozzle brick. But prices than brick high alumina brick, so with clay where you can meet the requirements without the use of high alumina bricks. General physical and chemical indicators of high alumina bricks brick has the following characteristics: the use of common brick to manufacture, supply, budget, construction and other sectors has brought great convenience. 1, adaptability. E.g., T-3 brick, almost the furnace can be used. 2, can cooperate with each other. Such as T-19, T-20 and T-52 brick arch angle can be used in conjunction with masonry arch and door. T-38, T-39 and T-61 brick arch angle can also be used in conjunction with masonry arch into the door. Not only with the use of common brick, and according to the radius of the situation span accurately calculates the number of silicon numbers and brick used. Yangquan Zhengyuan Refractories Co., Ltd. located in the famous township refractory materials - Yangquan, Shanxi. Local rich bauxite, is one of China's largest production base of refractories.
