Refractory materials refer to refractoriness of not less than 1580 ° C with inorganic nonmetallic materials and products.Refractoriness refer to refractory material conical specimen, in the absence of load, is resistant to high temperature and does not soften the fused Celsius temperature. But only the definition of refractories can not fully describe the refractory.1580 ℃ is not absolute.It is now defined as the physical and chemical properties that allow materials to be used in a high temperature environment called refractory materials.Refractory is a multi - phase, multi - element complex system, its service object is the high temperature industry.It is the basic material of service high temperature technology, the structural material of the thermal equipment such as building kiln, and also the functional material that makes some high temperature containers and parts or special functions. No matter in the production process or under the conditions of use, some of the properties displayed are related to the chemical thermodynamics, chemical kinetics and material structure of physical chemistry.The principles and rules of chemical thermodynamics, chemical kinetics and material structure are followed.So refractory materials at high temperature under the action of the successful use of, must have good mechanical properties, thermal properties, structure and use of performance, which have high refractoriness, refractoriness under load, volume stability, thermal shock stability, resistance to chemical attack, gas permeation resistance, scouring resistance, creep resistance, resistance to spalling and structural properties, such as peeling off.Ability to withstand various physical and chemical changes and mechanical functions to meet the requirements of thermal equipment and components. Refractory materials are generally made from natural ores such as bauxite, silica, magnesite and other raw materials.At present, high quality refractory raw materials and artificial synthetic materials such as mullite, spinel, silicon carbide and other raw materials are increasing, and the advanced refractory materials have been developed.The special refractory materials produced by pure oxide and refractory compounds have also been developed greatly.The refractory material in steel, non-ferrous metal, glass, cement, lime, ceramics, petroleum, chemical industry, machinery manufacturing, light industry, electricity, boiler, war industry, atomic energy, silicate, power and so on has been widely applied in various fields of national economy, is essential to ensure the production of industry and technology development on the basis of refractory materials.It plays an irreplaceable role in high temperature industrial production.Refractory materials and products have been driven by high speed development in the high temperature industry, and the industry of refractory materials has maintained good growth. China's refractory materials have become the world's largest producer and exporter of refractories, accounting for about 65 percent of the world's total production and the world's largest sales. Bauxite is one of the world's three largest exporters of bauxite.Magnesite reserves the world's largest, or graphite export power.

Warm congratulations on the smooth completion of supply contract with China central Africa mining Co., Ltd and my company. Early July 2017, my company and engaged in Henan Mingxin investment co., LTD. (Zimbabwe African mining Co., Ltd in Henan procurement and supply company), signed in Zimbabwe African mining Co., Ltd, invested by daily output 200 tons of lime production line of the supply of a full range of refractories (a total of 385.2 tons) of the contract. The production line is invested by China central Africa mining Co., Ltd., which is a supplier of the design and mechanical equipment of the Qianbaidu kiln technology company.Our company supplies a complete set of refractory materials. Our company passes on the entire range of refractory meticulously design, arrange production, on October 9, 2017, in accordance with the contractual requirements to Qingdao port of shipment, estimated two months security arrived in Zimbabwe, beira port.
