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.
Highest and firing temperature is the be out of shaping that influence product function does not appear when showing specific raw material amounts to this temperature in roast or other blemish. Basis of raw material of pottery and porcelain of avery kind of its are mineral of composition different, all existing one reasonable highest allow firing temperature or it is agglomeration limiting temperature. The purpose of roast is close to this as far as possible namely...
The tall aluminium that gives priority to brilliant photograph with Molaishi pledges we weigh fireproof material pledge gently for Molaishi heat preservation brick. General alumina content is in 65% ～ 75% between. Mineral composition divides Molaishi outside, contain alumina among them inferior person still contain a few glass photographs and Fang Shiying; Contain alumina taller person still contain a few corundum.
The electric stove fusion in nonferrous metal smelt is the electric arc that produces electric energy through electrode and charging place or the high temperature that make resistor place generation through melt slag directly come to what melt expects. Controallable fuse-element temperature is in 1200 ～ any temperature inside 1600 ℃ limits. The thing that fusion electric stove basically uses at fusion to contain part of a large number of difficult frit gangue...
Raw material is in broken and abrade hind still need to pass screening, because preform undertakes grading by the powdery makings of distinct size, can assure the most close together accumulation and obtain compact base substrate.
Wearability is fireproof material resists of the hard stock, gas that contain dirt wear away the ability of action. Be aimed at the environment with industrial kiln complex furnace, wait for equipment like room of carbonization of blast furnace shaft, anxious furnace, we choose wear-resisting function to finalize the design goodly fireproof material and adventitious fireproof material.
To common for tall aluminous brick, shape pressure should achieve what 137MPa; high density spends tall aluminous brick to shape pressure should be inside 176~215MPa limits. That is to say, the friction that introduces 250t above only presses bricky machine to form, ability obtains such result.
Alumina pledges heat preservation brick weighs light qualitative tall aluminous brick again gently. Alumina content is in 48% above, main the light qualitative fireproof material that constitutes jointly by Molaishi and vitreous photograph or corundum. With the liner that builds kiln furnace at build by laying bricks or stones and thermal insulation, and erode without stock of melt of intense high temperature reach erode the place of action. When be being contacted with blaze directly, the surface is contacted...
The chromic corundum brick that flourish Cheng Naicai produces a sale is to use special type technology of fireproof material production makes firebrick, can be improved and improve the immanent quality of goods, improve the high temperature capability of goods. Have fireproof degree of tall, intensity stability of big, thermal shock is good, fight corrode the characteristic with strong ability, the particular case of price of chromic corundum brick should to fireproof material...
The distinction of heavy qualitative brick and light qualitative brick is very big, their use environment, limits, function is not same. Different position can use different data, when material of choose and buy, we want the real case according to oneself, decide those who use to use which kinds of fireproof material to suit his.
Firing the working temperature of the belt not prep above 1200 ℃ , structure of layer of kiln heat insulation spreads felt of a fireproof fiber to rely on furnace casing first, pledge with clay adiabatic brick build by laying bricks or stones is built next, density of usable also bulk pledges gently for 0.8g/cm3 fireproof and pouring makings whole irrigates. Firing take working layer to use tall aluminous brick.
Expand seamed position should keep away from place getting power, be like the hole of framework of body of heater and liner, affect the integral intensity of fireproof material in order to avoid, expanding seam the premise that maintains reasonable span to issue even setting. Of hearth expand seam all answer in a hearth is the same as in fluctuation brick layer crisscross setting. Of boiler setting expand outside be being seamed inside mix between the layer up and down...
Brick of Mo Laishi corundum uses as in upside structure brick, makings path brick, cover board, metallurgy and other industry liner of lukewarm kiln furnace, carbon black reaction furnace is cold paragraph, other industry heats up labor facilities liner.
