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.
Our country uses magnesian calcium on finery is fireproof material only then at the beginning of 8O time. Magnesian calcic simple stuff is thermodynamic stability is good, fine effect beautiful, already regarded smelt as the lining of steel of class of high grade stage by stage.
Hearth beats dozen of way that expects just as its name implies is hit through pounding namely, because density of this kind of material is opposite,this is bigger, felt is spent bigger, cannot use quite irrigate built kind, use pound hit way to be able to make filling sufficient fill aperture, ensure structural stability.
Float bead the siliceous aluminium that pledges heat preservation brick is with the heat and power plant the floatation in fly ash comes out gently is qualitative glass is hollow bead body. Its body light, wall thin, hollow, surface is slick, high temperature resistant, heat proof quality is good. Use float bead these character, the adiabatic and fireproof material with superior performance of production heat preservation.
Current, outside including fine except steel, how to produce the fine effect of intermediate bag, improve casting base quality further, should cause from the following respect take seriously:
LF furnace is refined facility has electric steel water in steel bag, be heat with electric arc method of the fine outside the furnace that is main technique feature.
New 2014 castigatory " project of blast furnace puddling designs a standard " in regulation: The working fixed number of year of battle of furnace of blast furnace generation should achieve 15 years of above.
By pouring steel is planted smelt means and whether to need roast wait for a condition, intermediate bag distributes the following kinds of kinds roughly: (Wrap among 1) high temperature, for some setting of specific metallurgy process place uses magnesia brick liner to carry heat on the head to be controlled to 1500 ℃ .
Fireproof material regards a of cement kiln important construction as material, its build by laying bricks or stones builds the stand or fall of quality, the service life that affects cement kiln directly. Accordingly, regard fireproof material as manufacturer, provide reasonable construction technology support, can highlight oneself actual strength not only
There are a lot of phyletic kinds in firebrick, different, but differ with respect to one word between some firebrick, make person cent not clear have what difference, e.g. : Light qualitative firebrick and heavy qualitative firebrick.
Fine temperature is as high as 1700 ℃ and heat time is long, if with the 40tLF(V) that electric stove cooperates every furnace heats,time makes an appointment with 13~26min, blame with heat place temperature taller.
Groovy firing and fireproof material, the small air hole of certain amount and micro-crack exist between fireproof material, these small air hole and micro-crack can absorb gentle to see one part thermal stress below high temperature
Aluminium of Zhengzhou flourish Cheng Gao is pouring makings cry again fireproof and pouring makings, wait for composition by makings of fireproof aggregate, pink, bond, additive with pouring the indeterminate form of law construction is fireproof material. Have higher mechanical intensity and good heatproof shake, fight the function such as abrasion, basically use do furnace of kiln of hot-blast stove of boiler, blast furnace, heating furnace, pottery and porcelain to wait all sorts of...
