Q:How to use fire-resistant soil?: Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.

Q:What materials are needed to make the amorphous refractory bricks?: Amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive, and can be directly used without high temperature firing.

Q:I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!: Stable chemical properties. The crucible material should not be hydrolyzed at low temperature. It is difficult to be decomposed and reduced at high temperature and is not susceptible to corrosion by molten slag and molten metal;

Q:What are grades of refractory materials?: Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ - 1770 ℃, advanced refractories: 1770 ℃ - 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler, (ratio) Max: Min < 4: 1; Shaped ones: no more than two-entrant, (ratio) Max: Min < 6: 1 or having a acute angle of 50 - 70 °; The specific type :( ratio) Max: Min < 8: 1 or having no more than 4-entrants or having an acute angle of 30 - 50 °; and Special products: crucible, containers and tubes. 3, divided according to the method of manufacturing: burned products, non-burned products and unshaped refractories 4. divided according to the chemical properties: acidic refractory materials, neutral refractory materials and basic refractory materials.

Q:How many types of special refractories are there?: Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials

Q:The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.: 3, the selection principle of antioxidant and its thermodynamic and kinetic mechanism31 selection principles of antioxidants:(1) according to the thermodynamic data and the conditions of use, the possible condensed phase and the vapor pressure of each gas phase are determined;(2) compare the size of each coacervation and oxygen affinity, and the possibility of reaction with CO.(3) the influence of various reactions on the microstructure of brick was analyzed.The thermodynamic and kinetic mechanism of 3.2 antioxidantsFrom a thermodynamic point of view, at the operating temperature, the additives or additives that react with carbon react with oxygen more closely than carbon and oxygen, giving priority to carbon oxidation, thus protecting carbon;From the analysis of dynamics point of view: the compound additive with oxygen and carbon monoxide reaction changed the microstructure of carbon composite refractory materials, such as increasing the density, blocked pores, hinder the diffusion of oxygen and reaction products.

Q:About the use of horseshoe glass kiln refractories: the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric?smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.

Q:how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q:What are the chemical composition of refractory cement?: Calcium aluminate prepared by calcining as the main component. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. Refractory cement is also known as aluminate cement.
