Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
The furnace shall be made according to the type of refractory and the moisture content and the type of bond. Pay special attention to the discharge of free water and crystalline water, not too fast to prevent cracks!
Q:What are the structural properties of refractory materials provided by the manufacturer of the refractories include?
Metal oxides have very good resistance to high temperature, such as: three, two aluminum oxide, Magnesium Oxide...
Q:What are the applications of refractory?
Refractory materials are widely used in iron and steel smelting , glass, cement kilns, non-ferrous metal metallurgy, environmental protection, and chemical, etc. For example: For a car of 1.5 tons, do you you know how much refractory it use? The answer is: To produce top hat or other steel products, glass for vehicle windows, nonferrous metals kile aluminum and copper, plastic products of the body all needs refractory. A car of 1.5 tons needs to consume a total of 10Kg refractories.
Q:What's the material of electrical fire prevention board?
Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface. Hope my answer is helpful for you.
Q:What are the specifications of fireclay bricks?
1. The various classification criteria of clay bricks. First, according to the physical and chemical indicators, they can be divided into these types: (NZ) -42, (NZ) -40, (NZ) -38. Second, the classification of specifications of clay bricks is in line with the stipulations in "general shape and size of refractory bricks". Finally, according to the stipulations of relevant state departments, the clay bricks can be divided into standard bricks, ordinary bricks, special-shaped bricks, special bricks. Second, level of refractory temperature of refractory bricks The refractoriness of refractory bricks is divided into four levels according to changes of alumina content. We know that the components in clay bricks include Al2O3. Alkali metals are also included. The refractoriness of AAA-level clay bricks in Ruitai Refractory Material Factory is 1750 ℃; A-level bricks is 1730 ℃; B-level bricks is 1670 ℃; and C-level bricks is 1580 ℃. The softening temperature under a fixed load of Clay bricks is about 1350 ℃. Clay bricks, also known as sintered bricks, are small size artificial bricks for modern architecture. Clay bricks have good properties and high thermal stability, in which Fe2O3 content is less than 2.0 to 2.5%. Overall dimensions: 230 * 115 * 65mm
Q:Who knows about the grade C fireproof door materials?
There are no differences in the interior materials of the grade A , B and C fire doors, they all use fire rock wool boards. The only difference is the thickness of built-in fire rock wool boards. The rock wool boards' thickness of grade A fire doors is 52 mm, that of grade B is 46mm, and that of grade C is 40 mm.
Q:What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; Applications of ceramic fiber cloth: It can be applied to the thermal insulation of all kinds of furnaces, high-temperature pipelines and vessels; furnace doors, valves, flange seal, fire doors, fire resisting shutters and high-temperature furnace door curtains; engine and instrument insulation, clad material of fireproof cables, and high-temperature resistant and fire-proof materials; thermal insulation cloth for coverage, high-temperature expansion gap padding, and inner linings of the flue; high temperature resistant labor safety products, fireproof suits, high-temperature filtration and sound absorption, replacement of asbestos, etc.
Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?
How long is the fire resistance time of the AAA fire resistance rolling shutter door?
Q:How is grade of fire endurance divided?
You can search the answer on the Internet, thank you!
Q:What is unshaped refractory?
Plastic. From the production method, the plastic is between the concrete and the castable. It is made of refractory material by refractory material plant, which is made of plastic clay. The ingredient is a retarder. It is packaged by plastic bag, and construction and heat treatment are carried out on the spot. But the biggest problem is the application of plastic on the knotted Jiecha easy peeling, retarder dosage improper or is vulnerable to bad caking plastic hardening.
