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.
Rotary kiln is a floorboard, according to to calcine material cent is cement, lime, zinc oxide, rubbish to burn rotary kiln. Refer to please below the relevant content that arrange. If rotary kiln firebrick wants to use long firebrick, recommend the firebrick that uses long L to be 250mm actively. The non-working surface that still uses in certain place (cold face) dimension A is...
Fireproof but plastic and multi-purpose at kiln furnace liner repair, or it is to be used at cannot be built with firebrick build by laying bricks or stones or using a mould to use pouring makings irrigate built position, but the sizy agitate construction that plastic need uses form a complete set, cannot contact water. High temperature resistant but plastic liner is the fireproof material that cannot finalize the design in tamp structure, design of structure of its line system needs...
Founding not comes stone brick is made by earth of tall aluminous alumina or industrial alumina, straw or silica, fused in electric arc furnace, next mould anneal. Its are main and mineral composition is Molaishi. Brick of electric frit Mo Shi is raw material with tall aluminous alumina, by Molaishi sunlight is comprised (3Al2O3 · 2SiO2, character per cent is Al2O372% , siO228%) . Fused make an appointment with...
The system of light qualitative firebrick is usually secret small, basically use heat preservation, compression intensity is smaller, do not be able to bear or endure erode, not wear-resisting, do not contact blaze, cannot bearing. Intensity of compression of heavy qualitative firebrick tall, wear-resisting is able to bear or endure erode, do not suggest to use light qualitative brick to should weigh qualitative brick. Light qualitative firebrick pledges firebrick is to point to porosity gently tall, density is low (one...
Converter is fireproof environment of material lining work, working layer, filling layer and permanent layer include in converter firebrick lining. Working layer is mixed with molten steel, broken bits directly contact of heat vital energy, keep getting of the respect such as physics, mechanical, chemistry erode; Fill layer interpose is mixed at working layer between permanent layer, expect with tar magnesia or tar dolomite normally...
Hollow ball brick is the heat preservation brick that makes with the fireproof and hollow ball of diametical 3-5 millimeter, material qualitative content is high, good in effect of the heat preservation below very high temperature, the price is exceedingly high also. Apparent pore of hollow ball brick is small, thermal conductance is small, heat-resisting shake sex is good, intensity of high temperature structure is high, but immediate step is built within furnace of high temperature kiln, can produce high temperature heat...
Reverberator by furnace base, hearth, boiler setting, roof, into makings mouth, product exit and flue are comprised. Its are accessary equipment includes to take makings device, blast device, smoke evacuation device and unit of utilization of waste heat. In addition, still set on reverberator wall into door of makings mouth, job and cuttings pick-up mouth, furnace end sets perpendicular flue or inclined flue, reverberator front...
Smelt is fireproof data products is to point to batch of will fireproof material to fuse in electric stove even liquid, pouring into prefab mould, undertake anneal again. With electric frit fireproof data products differs, the powder that uses the electric frit data that legal system of agglomeration of high-pressured high temperature becomes namely and grain recombine product. The marked characteristic of founding product is: (1) hole...
From the point of the working environment of cementite furnace, its job temperature is not very tall, of cementite heat temperature is 930 ℃ about, gradient of furnace temperature change is not tall. Accordingly, from the point of temperature requirement, can choose average fireproof data. However, cementite furnace is reductive cementite atmosphere, requirement build by laying bricks or stones begs build by laying bricks or stones to build fireproof material to have be able to bear or endure ooze sex, liner of body of build by laying bricks or stones is able to bear or endure...
Corundum brick is the fireproof data products that gives priority to brilliant photograph with corundum, alumina content is more than 90% . Intensity of normal temperature compression is high (can amount to 340MPa) . High load bate begins temperature (be more than 1700 ℃ ) . Good chemical stability is mixed to acidity or basic slag, metal vitreous fluid has very strong resistance. High pure corundum brick. Corundum brick is extensive should...
Light-duty firebrick applies extensively in the furnace of high temperature kiln such as metallurgy, chemical industry, electron, glass, kiln roof ministry is structure of top of smooth condole of a kind of light simple fireproof stuff, can install condole to carry height on the head according to furnace temperature section, what can satisfy ceramic already is firing, narrowed again the temperature limits of shaft. High temperature resistant requirement of technology of body of bricky build by laying bricks or stones? 1. In the setting...
Melting point of silica brick of silica brick characteristic is higher, good performance getting power is had between 1640-1680 ℃ , its melting point is mixed in 1670 ℃ about Fang Shiying melting point (1713 ℃ ) between. 300 ℃ reach prep above approach melting point (scale quartz or Fang Shiying) silica brick volume is steady, the bulk when 1450 ℃ heating when using expands make an appointment with 1.5%-2.2% , be helpful for assuring...
