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.
The unit price of corundum Mo Laishi asks to wait according to technology of raw material, production, client change and change. Mo Laishi brick uses corundum high grade synthesis is Molaishi, high pure corundum is main raw material, add special type additive, classics high pressure shapes, high temperature fire and into.
Accelerate industrialized process further as the country, the market of domestic fireproof stuff greeted the gold period that the industry grows, market current situation basically is in the phase that demand exceeds supply.
Electric frit not comes stone brick is raw material with tall aluminous alumina, the composition that matchs different alumina Molaishi (3Al2O3 · 2SiO2, quality per cent is Al2O372% , SiO228%) . Melt is controlled in 2300 ℃ , issue mould at 1850 ℃ within sand mold, undertake anneal next in order to eliminate stress.
Weight of brick of general T3 tall aluminium is 4.5kg, bulk is 1689cm3, dimension is 230*114*65. Brick of T3 tall aluminium thermal stability is tall, fireproof degree in 1770 ℃ above, the sex that fight broken bits is better.
Mo Laishi pledges gently effect of bricky quality light heat preservation is good, it is makings of high grade high pure and fireproof pink, press product demand proportion, join organic and compound filler, via vacuum extrusion, high temperature burns the product of light qualitative Mo Laishi that combines.
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 ℃ .
