Which in July the total export of refractory clay is about 102,400 tons, an increase of 29.1%; export amount of about 1,788,400 US dollars, an increase of 36.3%. In July, according to trade statistics, the top ten were Dutch (17548.72 tons), Japan (16623.14 tons), the United States (9348.99 tons), India (9032.00 tons), Belgium (6591.25 tons), Turkey (6100.60 tons), Italy (5637.75 tons ), France (4330.04 tons), Iran (3393.50 tons), Taiwan Peng Jinma tariff area (3142.00 tons).

Energy and environmental problems to the iron and steel enterprises and the ceramic industry and other industries to bring the rapid development of restrictive effects, energy saving and reduce emissions is the enterprise technological progress and can be the energy and environmental pollution, energy and environmental pollution, The inevitable choice for sustainable development. Industrial furnace is the key equipment for industrial heating, widely used in the national economy of high temperature industry. Industrial kiln is also a large energy consumption, its energy consumption accounts for 25% of the total energy consumption, accounting for about 60% of total industrial energy consumption. In the energy saving process of industrial kilns, in addition to heat source transformation, sintering process transformation, combustion process transformation and furnace structure transformation, the furnace refractory and kiln refractory material performance is good or bad energy saving effe

Classification: A、 Classification by chemical composition (1) Silica products; (2) aluminum silicate refractory products ; (3) Magnesium refractory products; (4) dolomite refractory products; (5) chrome refractory products; (6) carbonaceous refractory products; (7) zirconium products; (8) special products. B、 By chemical characteristics (1) acidic refractory. Acid refractory material is based on silica as the main component of the refractory material, mainly refers to the silica brick and zircon brick. Acidic refractory materials can be resistant to acid slag erosion. (2) neutral refractory. Neutral refractory mainly refers to refractory materials such as corundum refractory brick, high alumina brick, silicon carbide brick, silicon nitride brick and carbon refractory brick, mainly made of aluminum oxide, chromium oxide, silicon carbide and carbon as the main components. Its characteristics are acidic slag and alkaline slag have a corrosion resistance. (3) alkaline refracto

Refractory brick masonry should be staggered brick joints, brick need to use refractory mud (dry puzzle with dry refractory powder) to fill, masonry process until put into production, to prevent masonry damp. In order to compensate for the volume expansion of the masonry after heating, the masonry needs to be designed according to the design and specification requirements. Refractory brick masonry wall, bottom, roof, pipe lining, brick lattice, combined brick masonry and expansion joints set aside. Masonry wall in accordance with its form is divided into two types of straight wall and curved wall. Straight wall before the masonry, the furnace floor should be the lowest level of the base surface leveling, on the basis of the furnace or steel structure according to the construction line. Measuring the vertical and horizontal center line and other reference line, in ensuring the size of the various parts of the furnace under the principle of accurately find the wall size line. Wall

High alumina bauxite clinker is calcined bauxite. Generally,before Alumina Bauxite in the production of high alumina refractory bricks are  the calcined, get clinker, that is, barren material. With this High alumina bauxite clinker as the aggregate in the ingredients, can guarantee the volume stability of the refractory bricks and the size of the accurate. China's bauxite is mostly D-K type, in the calcination process to be decomposed dehydration, secondary mullite and re-crystal sintering three stages. The calcined mineral composition forms corundum, mullite and glass phase according to the ratio of Al2O3 and SiO2 in the raw material. High bauxite clinker is gray, light yellow and dark gray. It is mainly used to produce high alumina refractory bricks, can also be used to make fused corundum. The two major causes of sintering of high alumina bauxite are secondary mullite and liquid phase effects. The former depends on the Al2O3 ratio, which hinders the sintering effect; the la
