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.
Characteristic of brick of phosphatic tall aluminium: 1, have fight chemical aggressivity goodly, and fight alkaline ability far excel clay brick, tall aluminous brick. 2, have relatively high strenth, wearability is good. 3, have good heatproof shake sex. Cent is phosphatic firebrick phosphatic brick and phosphoric acid
Our country's existing hot-blast stove has 4 kinds of forms: 1, internal combustion engine 2, outside light type 3, the top lights type 4, ball type hot-blast stove. Advantage of type hot-blast stove lights outside: Field of the temperature inside regenerator distributings evener, the combustion inside firebox is complete, the structure is stable. Defect: Invest tall, structure
Fireproof and pouring makings and wear-resisting but plastic and main distinction has, of construction means different, fireproof and pouring makings construction needs to make mostly grind, wear-resisting but plastic do not need. Of use means different, fireproof and pouring makings need adds water to combine agitate, and wear-resisting but plastic need is used
Corundum is to use high grade aluminium to alumina is machined through special technology and be become, have hardness good, cleanness spends tall, tenacity tall, light transmittance good, particle shape good, Bai Gangyu small pink particle size distribution is narrow, product wearability is strong wait for a characteristic. What corundum makes technology according to its is different,
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
