Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
Mineral wool is one kind uses metallurgy broken bits to be the man-made fibre that main raw material produces, manufacturing technology includes: Fluid of already will fused hot broken bits adjusts what composition makes to achieve corresponding requirement, heat up broken bits fluid to be cast through centrifugal high speed after that swing a fiber, fiber classics is collected, arrange and solidify gets the product such as mineral wool board, felt. Fluid of hot broken bits is used normally strong...
Steel is packed is the indispensable container in steelmaking process. As the ceaseless development of steel-making technology, especially the processing of LF of the fine outside furnace and RH, its action from the simplest fill the forge that receives molten steel to develop to have certain smelt function. Molten steel stays for a long time in steel to pack in, inevitably meeting causes the loss of molten steel temperature, heat conduction...
The manufactures craft and tall aluminous brick production technology of sleeve brick is same, alumina content is in a kind of neuter and fireproof material of 48% above, by content of alumina of etc of tall aluminous aluminous grog maximum pressure of higher raw material classics shapes to be become with to calcine. Sleeve brick sheds steel brick item characteristics (1) high temperature wear well. (2) good heatproof shake sex. (3...
Not come to what Shi Zhuanchang uses gently to note an oar to shape character method, natural conserve comes drawing of patterns, immigrant drier is dry, finish fire in high temperature next, after classics machinery is abrade firing base substrate. The order of feed in raw material when agitate is: Join fireproof raw material first, mix is even, mix of rejoin sawdust pink is even, add water again. The affiliation of water measures ordinary control to be in...
Of firebrick of heavy qualitative Mo Laishi advocate brilliant photograph is Molaishi, fireproof degree be in 1850 the left and right sides, loading bate temperature is high, rate of high temperature creep is low, heatproof shake sex is good, acid-proof sex is slaggy erode. Brick of heat preservation of light qualitative Mo Laishi calls Molaishi adiabatic firebrick, basically be the fireproof material that gives priority to mine photograph character with siliceous aluminium, have good heat preservation heat insulation...
Mine hot stove is the main facility of ferroalloy smelt, the flying development as industry of our country ferroalloy and suffer a country to be opposite high cost can the macroscopical adjusting control of the enterprise, and size of mine hot stove is large in recent years the development that change, lining serves as the substantial of body of heater, erode in the machinery that high temperature high fever and charging, slag bears in smelt process and physics...
Qualitative, porosity concerns the coefficient of thermal conductivity of firebrick and material, namely bulk density, the material qualitative sort of firebrick is more, the coefficient of thermal conductivity of carborundum is bigger, the coefficient of thermal conductivity of brick of light qualitative fireproof heat preservation is smaller. The stoma in firebrick of firebrick of light qualitative heat preservation is affected to what heat conducts, according to degree of stomatic amount, size, UniCom...
The pace enters lining of bridge type heating furnace is to bear the main construction part of thermic load, its construction quality achieves a design to heat up industry index to having decisive effect to heating furnace. Complication as what the application of new-style and fireproof material reachs furnace design, construction difficulty is greater and greater, to lining construction quality control posed bigger challenge. Current, ...
Kiln furnace is high temperature equipment, do good heat preservation to be able to reduce waste of quantity of heat, managing the sources of energy, what does the light qualitative firebrick with kiln furnace commonly used heat preservation have, detailed introduction looks please below. 1, light qualitative silica brick pledges silicon pledges adiabatic brick is the Si02 content that controls for main raw material with silica gently do not be less than the adiabatic and refractory products of 91% . Brick of qualitative heat insolation of light qualitative silicon...
The weight of light qualitative firebrick is lighter, can reduce kiln furnace to bearing the burden of place, bricky interior is distributinging equably a lot of stoma, can have good heat preservation and energy-saving effect, common product has brick of qualitative heat preservation of clay, diatomite, tall aluminium, Molaishi, silicon to wait. Pledge heat preservation firebrick and common firebrick are compared gently, heavy...
Boiler liner is easy wear away to have very big concern with select material, construction, drying-out, fireproof material can reduce the wear-resisting with right choice maintenance frequency, furnace letting kiln produces more economic value. Furnace is to use coal to make fuel for the most part, minority uses heavy oil or gas, basically wait for composition by boiler canal system, firebox, flue, dust collector...
Firebrick uses Mo Laishi to synthesize Molaishi artificially, press product demand proportion, join organic and compound filler, via vacuum extrusion, high temperature burns the product of light qualitative Mo Laishi that combines. Pledge gently by right of its and the characteristic with heat preservation superior performance, the hot side that Mo Laishi pledges firebrick applies extensively at a variety of hot project facilities gently is fireproof line or protect...
