Q: What are the models of refractory cables?: The models of refractory cables: NH-KVV22 copper core flame-retardant PVC insulated and fire retardant control cables with steel belt sheath NH-KVVRP copper core flame-retardant PVC insulated and fire retardant shielding control cables with steel braiding sheath NH-KVVP2 copper core flame-retardant PVC insulated and fire retardant shielding control cables with sheath and steel belt wrapping NH-KVVRP2 copper core flame-retardant PVC insulated and fire retardant shielding soft control cables with sheath and steel belt wrapping NH-KFF copper core fluorine plastic insulated and fire retardant control cables with sheath NH -KFFR copper core fluorine plastic insulated and fire retardant soft control cables with sheath NH -KFFP copper core fluorine plastic insulated and fire retardant shielding control cables with sheath and copper wire braiding

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: Who can tell me what is neutral refractory?: It is a material that can resist acidic and basic slag, flux and chemical erosion form other refractories at high temperatures. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc. Sometimes, high alumina refractories with high Al2O3 content also belong to this material, such as some materials that are acidic but tend to be basic refractories, like sillimanite, mullite bricks and corundum bricks. Recently developed aluminum carbon bricks, zirconium carbon bricks alumina - silicon carbide - carbon bricks, silicon nitride bonded silicon carbide brick and so on are also neutral refractories. This material can be used in the bottom of blast furnace, the lining of hearth and bosh, and the lining of aluminum electrolytic cell, calcium carbide furnace, ferroalloy furnace, molten steel ladle, plating tank, reaction tank, and autoclave and so on.

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke

Q: What things and cement mixed can act as refractory?: Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.

Q: Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?: (1) the height of buildings is greater than or equal to 24 m, the combustion performance of thermal insulation material should be A-level. (2) the height of buildings is less than 24 m, the combustion performance of thermal insulation materials should be A- or B1-level. When using B1-level thermal insulation materials, fire barrier zone should be set in each floor. (3) incombustible materials should be used as the protective layer of thermal insulation materials. Thermal insulation materials should be completely covered by protective coatings. The thickness of protective layer should be no less than 3 mm. (4) The base walls should be set in buildings with nontransparent curtain wall structures of metal, stone,etc. The fire endurance of which should comply with relevant provisions of current fire?safety?rules on fire endurance of external wall. The fire endurance and fire protection construction of pier?between?two?windows, window sill walls, skirt walls of glass?curtain?walls should comply with relevant provisions of current fire?safety?rules on building curtain walls. (5) the internal cavity of base walls, as well as the space between the skirt wall and base walls, pier?between?two?windows, window sill walls should be sealed with fire-proof sealing materials at each floor.

Q: What are the classifications of refractory? Which category does steel ladle castable belong to?: In addition, it can be divided into refractory, shapeless refractory material. And it can also be divided into acidic refractory, basic refractory and neutral refractory. If you want to know more, you can ask thme. In fact, every company has different refractory clasifications. There are more clasifications in Huaheng.

Q: what are the types of piping insulation material fire?rating?: There are two grades: 1, the organic material: Grade B Grade B1 hard combustion (fire?retardant) 2, inorganic materials: class A no burning it is divided into three levels, attributed to the types of materials!

Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?: Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material. If it is glass fireproof door, then the door frame should be equipped with fire-proof materials. I know a exclusive shop in Beijing dealing with fireproof doors, called Naecame.
