Refractory are made of various types of refractory materials under specific technological conditions, and are subjected to a variety of external conditions either individually or in combination during their use, therefore, there must be a variety of Refractory with different properties to meet the specific conditions of use, and the types and properties of refractory materials used are also varied, let's take a look together.
According to the formation of raw materials can be divided into two categories of natural raw materials and synthetic raw materials, natural mineral raw materials are still the main refractory materials. At present, oxygen, silicon and aluminum account for about 90% of the total elements in the Earth's crust, and oxides, silicates and Aluminosilicate minerals are the predominant natural refractory materials with huge reserves. The main varieties of natural refractory raw materials are: Silica, quartz, diatomite, wax, clay, bauxite, kyanite group mineral raw materials, magnesite, dolomite, limestone, magnesium Olivine, Serpentine, TALC, chlorite, Zircon, Zircon, perlite, chromite and natural graphite, etc. . Natural raw materials usually contain more impurities, unstable components, large fluctuations in performance, only a few raw materials can be used directly, most have to be purified, graded or even calcined to meet the production requirements of refractory material factory.
The range of natural mineral materials available for the production of refractory materials is limited and they do not meet the special requirements of modern industry for high quality and high technology Refractory. Synthetic refractory materials have been developed rapidly in recent decades. These synthetic refractory materials can fully meet the needs of people's pre-designed chemical mineral composition and structure, quality stability, is the modern high-performance and high-tech Refractory of the main raw materials. The methods of synthesizing refractory materials are sintering method and electric fusion method. Commonly used synthetic raw materials are: mullite, magnesia-alumina spinel, zirconium mullite, cordierite, aluminum titanate, silicon carbide and so on.
Therefore, we should select the raw materials according to the right time when selecting the Refractory. We implement comprehensive quality management, have a sound quality assurance system, and all links are produced and tested according to the enterprise standards approved by the technical supervision department, invited guests from all walks of life to come and patronize!
