Introduction Yangquan positive element Refractories Co., Ltd. is a professional manufacturer of Shanxi firebrick, high alumina brick production quality assurance, product manufacturers can be trusted name: T-20 high alumina brick Material: High Alumina (trioxide aluminum) Specifications: 230 * (65/55) * 114 high alumina bricks, the main component of aluminum oxide (Al2O3), which is higher than 48% Al2O3 content of silicate refractories products, if the Al2O3 content of> 90% called corundum bricks. However, due to various countries in different regions of resources, so the standard is not the same countries, such as European countries require high alumina refractories shall be greater than 42% Al2O3, and China for more than 48 percent in China, according to the aluminum-containing alumina bricks amount that Al2O3 is usually divided into three different levels. Ⅰ etc. ──Al2O3 content> 75%; Ⅱ like ──Al2O3 content of 60 ~ 75%; Ⅲ like ──Al2O3 content of 48 to 60%. As for the shape of the 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 bricks, if the shape is very irregular, then commonly called specific type alumina brick, In short, according to the specific use of the kiln to custom, which produce according to drawings. Alumina bricks classified according to their physical and chemical indicators are divided into general alumina bricks (LZ) and low creep high alumina brick (DRL) alumina brick Features: a, refractoriness refractoriness than alumina brick brick brick and half refractoriness to be higher, up to 1750 ~ 1790 ℃, is an advanced refractories. b, load softening temperature as high alumina products in high Al2O3, less impurities, forming fusible vitreous less, so load softening temperature higher than the clay, but do not form crystalline mullite network organization it still does not load softening temperature High silica brick. C, slag resistance of Al2O3 alumina bricks are more close to neutral refractories, can resist the erosion of acid and alkaline slag slag, because it contains SiO2, so weak resistance to basic slag slag acid resistance than ability more. Alumina brick masonry is mainly used for blast furnace, stove, electric roof, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina bricks are also widely used open-hearth regenerative checker brick, pouring system with plugs, intake bricks. But prices than brick high alumina bricks, so with clay where you can meet the requirements without the use of high alumina bricks. About Us Yangquan positive element Refractories Co., Ltd. located in the famous village of refractories - Yangquan. Local rich bauxite, is one of China's largest production base of refractories. Founded in 1995, 16 million yuan in fixed assets, the annual output of 20,000 tons. The company's advanced automated production equipment, gas sintering process and improve the service in the industry counterparts enjoyed a high reputation, and was awarded the units of energy saving pacesetter companies. Our main products are high alumina bricks, high alumina insulating bricks, high alumina semi-insulating bricks, clay, clay insulation bricks, insulation bricks diatomite, perlite insulation tiles and other specifications of various monolithic refractories; castable, ramming unshaped refractories hot fill material, plastic, spray paint, refractory mortar, such as different grades; bauxite (raw material, clinker, aggregates, powder), homogenized material, silica, quartz, feldspar different levels of fire-resistant materials. Enterprise products sold throughout the country and exported to Europe, America, Japan and Korea. We adhere to honesty, quality products, perfect service, cross-world friends.
