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.
Channel of blast furnace taphole uses the function of fireproof material and construction demand: Taphole advocate because channel wants to endure periodic slaggy chemistry is eroded, fireproof material must satisfy line of the channel before furnace as follows performance demand: 1, have admirable high temperature wearability, be able to bear or endure molten iron and erode slaggily can
Blast furnace uses fireproof data, must maintain the stability on physics and chemistry to the reaction inside furnace, should achieve the following requirement: (1) fall in high temperature, not fused, not bate, do not volatilize; (2) should have construction of body of heater can hold below condition of high temperature, high pressure complete strong
Do not touch aluminium pouring expecting is with fancy tall aluminous alumina aggregate is given priority to, add - Al2O3 small pink, palm corundum fine pink and a kind of additive, with aluminium acid calcic cement is bond, of preparation fireproof and pouring makings, detect respectively the index after its normal temperature and high temperature are burned. The result makes clear, this
RH fine full name takes off gas fine law circularly for RH vacuum. 1959 by German invention, among them the first letter that RH is two manufacturer that Germany uses RH fine technology at that time. Material of liner of RH of foreign part country is qualitative with life: The factory fastens vacuum room capacity / T vacuum room
Craft of VOD furnace decarbonization, it is a kind of technology that is used at element of material emergence carbon. Function of VOD furnace firebrick: The project combines recombine of magnesian chromic brick directly magnesian chromic brick half recombine magnesium is chromic bricky tall calcium is magnesian dolomite brick is magnesian dolomite brick MgO/% 73.0 50.7 53.4 79.3 87.5 Cr2O3/
Acid-proof brick: 230*113*50mm;230*113*55mm;230*113*65mm is acid-proof ceramic tile board: The acid-proof brick of all 150*150*15/20/30mm;200*200*15/20/30mm;300*300*15/20/30mm;150*75*15/20/30mm batch and norms and acid-proof ceramic tile board anticorrosion effect is same, distinction exists only
How much is firebrick price? The price of firebrick reachs norms requirement, firebrick to need to use the respect such as place to differ according to making body of raw material, brick, the price also has very big difference, believe according to the sort introduction of above everybody had certain knowledge to refractory products, stick
Mo Laishi is Al2O3 -SiO2 n duality the binary compound that fastens middling to press next only stability to exist, chemical type is 3Al2O3-2SiO2, natural Molaishi is very little, wait for artificial synthesis with agglomeration law or electric frit law normally. The Al2O3 71 in academic composition. 8% , siO2 28. 2% , it is AI2O3-S
The chemical composition of fireproof material is to point to the compound that makes fireproof material, also weigh chemical composition. Generally speaking, different fireproof material has different chemical part, and fireproof material presses avery kind of how much can the content of each composition divide into two parts again,
Pouring expect and fireproof but before plastic distinction, say both composition has simply first why to distinguish: Fireproof and pouring expecting is the compound that comprises by fireproof collect makings, bond and additive. Fireproof can be comprised plasticly and fireproof and pouring makings is similar, be mix by fireproof aggregate
Reflex of metal of heat insulating materials of accept Mi Konggui is compound model highest use temperature is in heat preservation structure 800 ℃ (stainless steel) above, its coefficient of thermal conductivity not only under material of inorganic and poriferous grain, and also under mineral wool. Metal of heat insulating materials of accept Mi Konggui reflexes combination heat preservation to written guarantee
Firebrick is built in the build by laying bricks or stones on industrial furnace is to cannot leave binder of fireproof slop, answer to had allocated place with slop first before build by laying bricks or stones builds firebrick, the largest size of slop looks several should not exceed 20% what build by laying bricks or stones builds a brick to seam, what what use the manage of slop to change function index to want to be built with build by laying bricks or stones is fireproof
