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.
Guiyang, guizhou Province provincial capital, abbreviation is built, Jin Zhu, have " Lin Cheng " beautiful praise, get a name because of churchyard expensive Shan Zhina, service center of travel of base of the liaison man with center of the politics that is Guizhou Province, economy, culture, science and education, traffic and principal southwest, signal center, industry and trade.
Argillaceous brick is the argillaceous simple product that shows Al203 content is aluminous material of 30% one 40% silicon acid. Argillaceous brick is to use the soft qualitative clay of 50% and grog of 50% horniness clay
So, the porosity that how can just reduce tall aluminous brick appears particularly important. By Zhengzhou flourish next Cheng Naicai introduces how to reduce the porosity of tall aluminous brick for you.
Steel structure is in normally 450 ～ can lose carrying capacity in 650 ℃ temperature, produce very big deformation, bring about steel column, girder to bend, because the result crosses big deformation and cannot continue to use, do not add the fireproof limit of protective steel structure to be 15 minutes or so commonly. This for a short while accident still is concerned with the speed of component part absorption of heat.
With alumina - the brick of high-powered chromic corundum that oxidation chromium produces for main raw material, have fireproof degree of tall, intensity stability of big, thermal shock is good, fight erode the characteristic with strong capability, in using, be able to bear or endure erode, wear-resisting caustic is fought erode, fight a structure to flake, already obtained favorable use result in metallurgy, glass, carbon black, petro-chemical industry.
The main use of mud of aluminous acerbity brine and the note that are used at construction work
Zhengzhou Rong Cheng has complete set to produce wear-resisting product advanced equipment, rely on hill aluminium resource of high grade product, my Zhengzhou flourish fills main product to be ball of microcrystalline wear-resisting tall aluminium, zirconia ball, high pure alumina filling ball, scaleboard of wear-resisting pottery and porcelain, line of wear-resisting pottery and porcelain piece, brick of line of ball mill pottery and porcelain
Rare earth of coating of silicate heat preservation wipes fabrics to wipe fabrics asbestine of compound silicate bubble board aluminous felt of silicon acid of siliceous aluminous warming plate is siliceous asbestine of mud of asbestine of velveteen of stone of blanket of aluminium board pinprick board cloth of fine of Bo of aluminum foil of adhesive plaster of aluminum foil of glass reinforced plastics of aluminum foil of heat preservation hammer is fireproof fiber cotton is fireproof blanket of fiber of pottery and porcelain
Cement kiln warm-up takes / cent ungird / transfer belt / firing belt / cooling zone / kiln mouth uses fireproof material to should choose so:
Indeterminate form is fireproof material to prolonging lining life, the exercise rate that raises equipment, drop work intensity and simplify the respect such as technology of fireproof material production will rise to promote action.
Fireproof mud is comprised by fireproof pink makings, bond and additive.
A few days ago, henan province is concerned be able to bear or endure material project puts on record through allow. These projects involve investment in all 86 million yuan, it is respectively:
