Q:Is the ball mill used in production of refractories?: Refractory is a kind of non-metallic material that is of resistance to thermal shock and chemical erosion, low thermal conductivity and low expansion coefficient. The refractoriness of the refractory is not less than 1580℃. The usage of the refractory is broad. Refractory materials include refractory bricks and powders. Abandoned refractory bricks can be recreated as new bricks after they are crushed by a crusher and grinded by a ball mill. The ball mill and crusher are needed to grind and crush the material in the production of the refractory. The ball mill produced by Zhengzhou Xinhai Machinery Manufacturing Co. has excellent performance and there are many successful cases in Inner Mongolia, Heilongjiang and Guangdong. At the request of the national environmental policy, the company adjusts the equipment details, allowing the equipment to ensure the volume of production while reduce energy consumption.

Q:What parts of cement kilns are refractories used on?: Generally they are used in cyclone, feed pipe, and duct and refractories are high-strength alkali-resistant castable, calcium silicate board, high-strength alkali-resistant brick, dome-shaped alkali resistant brick. Refractories in smoke chamber are high-alumina refractory castable, anti-skinning pouring material and calcium silicate board. Refractories in duct are high-strength alkali-resistant bricks, calcium silicate boards and steel fiber reinforced castable. Refractories in hooding parts of kiln are high strength castable high alumina and calcium silicate board. Refractories in rotary kiln are phosphate bonded high alumina brick, silmo brick, magnesia chrome brick, steel fiber reinforced castable. Refractories in grate?cooler are vault alkali brick, high alumina refractory castable, steel fiber reinforced castable and calcium silicate board. Refractory in coal burner is dedicated castable for coal burner.

Q:Is there requirement for radiation indicator in refractory?: All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.

Q:What are the refractories for converter?: Magnesia carbon material with large surface repair vessel, in addition to supporting the use of magnesia and magnesia cement.

Q:Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: First of all, customer requirements, packaging according to customer requirements. According to the packaging packaging tray packaging is divided into 40 yuan / tons, carton 70 yuan / tons, 40 yuan / ton, straw packing bags of 30 yuan / ton.

Q:What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?: Insulation materials. Thermal insulation material is characterized by thermal insulation, which is one of the four traditional inorganic nonmetallic materials. Fire?retardant material is cahracterized by heat-resistant. Refractory is a kind of materials of resisit high temperature. Fireproof material, which is different from thermal insulation material and refractory, is a synthetic material with some fireproof subtrate added. It is essentially resistant to high temperature.

Q:what's the classification of fireproof and thermal inuslation matertial?: Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.

Q:can slag tailings be used to be the base materials of refractory materials ?: perhaps not, because it has many pores.

Q:Does the refractory material used in steelmaking all refer to refractory brick?: For example, refractory castable doesn't only refer to refractory brick, but also some bulk material and ramming?mass. Desulfurizer belongs to ferrous metallurgy auxiliary material.

Q:Who knows about the fire endurance of sintered shaly hollow bricks?: 1. after roasting at high temperature of more than 1200 degrees, shale burned bricks in construction works can be free from expanding with heat and contracting with cold. 2. masonry walls can be plastered with no needs of any anti-cracking, reinforcement measures, and walls will not bulge and crack, which can reduce the construction cost, as well as are preferred building materials of frame structural engineering. 3.They have good sound insulation and thermal insulation performances, are one of the green building materials that the state currently promotes. 4. They have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance.
