Ceramic Fiber Blocks For Thermal Insulation

Q: what kind of refractories is used to make the industrial silicon furnace mouth long life?: Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.

Q: What requirements should refractory materials meet?: Ladle is an necessary equipment to undertake molten steel and continuous casting. As many kinds of steel needs to be processed in the ladle, including argon blowing tempering, alloy composition fine-tuning, refining dusting and vacuum processing, working conditions of the ladle lining have worsened. Their working conditions are as follows. (1) The temperature of molten steel is higher than mold casting ladle. (2) the molten steel stays longerin the ladle. (3) ladle lining are subjected to volatilization and agitation of molten steel under high temperatures and in vacuum. (4) The impact on the lining when undertaking steel liner when the impact effect. Therefore requirements of the ladle refractories are as follows: (1) It can resist high temperature. Molten steel should be able to withstand high temperatures without melting. (2) It can resist thermal shock and can withstand molten steel without cracking and spalling. (3) It can resist slag erosion. The ladle should be able to withstand the erosion of lining caused by slag and alkalinity changes of slag. (4) it should have sufficiently high temperature mechanical strength to withstand the agitation and scouring of molten steel. (5) lined should have certain swelling property so that lining will be united as a whole under the effect of hyperthermal molten steel.

Q: Development trend of refractories: Facing the survival and development of refractory industry challenges in many aspects, serious: 1, the user industry due to the progress of science and Technology (such as iron, iron and steel industry in the direct reduction furnace, to reduce casting, slag splashing etc.), reduce refractory material consumption; 2, refractory material environmental protection and ecological requirements; 3, users of the product quality and cost requirements; 4, users risk transfer, refractory material, the design requirements of the liner construction, maintenance services, and even provide construction equipment; 5, between refractory enterprises and personnel dispute price; 6, due to the industry downturn in some countries, the decline in refractory material and the lack of education, lack of young professionals; 7, resource depletion and other raw materials.

Q: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?: The sand is used as the filling material for the bottom of the ladle. Zhengzhou real iron refractory Co., Ltd. is specialized in the production of non-ferrous industries. All kinds of refractory materials used in glass kilns and cement kilns are sold directly by manufacturers. The prices are reasonable.

Q: What is the new fireproofing standard of external wall thermal insulation materials?: 1, The height of fire barrier zone is not less than 300, and the thickness is same to the external insulation system; 2, the horizontal dividing joint should be set on the boundary between fire barrier zone and thermal insulation system; 3, Fire barrier zone is usually set in the horizontal direction, the fire barrier zone should be set above the door and window openings, the distance between the low edge of barrier zone and upward side of the hole should not exceed 500mm; 4, The construction of fire barrier zone insulating layer should carried on from bottom to top with EIFS insulating layer, which is not first leave the place in the EIFS insulating layer, and then paste fire barrier zone insulation board; 5, pasting the insulation board fire barrier zone insulation board and EIFS insulation board should be stitched closely, the width is more than 2mm gap application EIFS insulation materials or fire-retardant foam polyurethane padding;

Q: Does refractory belong to metallurgical auxiliary materials?: Refractory includes metallurgical auxiliary materials.

Q: What kind of refractory decorative board has good quality?: The unique design and personalized style of well-known brand "transit" rank highest in the field of domestic refractory slab. It is one of the largest manufacturers of high pressure decorating refractory slab in China. The production base covers an area of 40,000 square meters and the annual output is 4 million. It passes the test of Quality Supervision and Inspection Center of National Fire Protection Building Material and ISO9002 certification. The products pass international standards such as 4586, the United States NEMA and so on.

Q: What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?: 2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent

Q: What is neutral refractory? Can refractory suppliers tell the main components of it?: The material using Al2O3, clay, bauxite and corundum as the main components is neutral material; the material using MgO and CaO as the main components is basic material; the material using SiO2 as th emain component is acidic material.

Q: What are the additives and recipes of refractory?: Trimeric major role played bulk water reduction effect can be considered strong trimer strong bleeding effect'm sure Hey lignin sulfonate water-reducing effect of the strong retarding superplasticizer effect in two critical recommendations with more money to buy homes are equipped who is willing to disclose ah experiments to solve the problem through Chuk Wan
