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 of check of appearance of classics of heat preservation brick after giving pit, manage changes function certificate of proof, with 200 ℃ roast 2h, the macerate in the phosphoric acid that makes up beforehand is entered in hot state transfer to a lower level. In macerate process, the open pore infiltration of brick of phosphoric acid edge, with the brick medium SiO2, Al2O3 reacts, make phosphatic compound, fill up at air hole in, reduce consequently...
In recent years, the fireproof data industry of our country gained very great success, mastered the production of the firebrick of earth of tall aluminous oxygen of all sorts of grade, the manufacturing technology of the Mo Laishi firebrick that ought to put forward especially among them and recrystallization corundum firebrick. Mo Laishi firebrick besides have very tall fireproof degree beyond, still have very high density and opportunity...
Firebrick is applied to widely metallurgical industry, mechanical production industry, experienced anxious industry, power industry and a series of major industry department, for example chemical industry and include itself of fireproof data industry inside silicate industry. The main service object that we also had mentioned firebrick is metallurgical industry. Accordingly, below will be main...
Below the premise condition that fireproof material secures in chemical composition, the uniformity that distributings as a result of composition differs with what machine craft, size of the mineral sort that makes goods medium, amount, grain and combinative position are different, of this kind of micromechanism different, create the difference of goods function. For example, the silicon simple product with Si02 same content, because of Si02...
It is early at the beginning of 90 time, england thinks the scientist realises applied lithofacies learns a method to study the value of fireproof material, put forward about all sorts of mineral groups in fireproof material yuan the deeply touched that concerns between structure and photograph reads aloud. Getatable data is very commendable, the fireproof stuff that can know to make one gives chemical composition not only how...
The fireproof data that place of alkalescent converter steel-making requires, general situation rises nothing more than two kinds, one kind is the alkalescent firebrick of preparation lining, one kind is the argillaceous qualitative firebrick that gating system uses. In at present the whole people makes iron and steel greatly, converter steel-making develops quickly and each district is fireproof the circumstance of general special still weakness lays data industry foundation, how much faster...
Developing the fundamental way that fireproof material produces roof is to should increase Fang Mei the crop that the high density with brick of Shi Jianjing stone and firing high temperature spends magnesian chromic brick, with assuring the need of black metallurgical industry adequately. In the meantime, must improve the composition of open-hearth furnace roof. Fireproof material still can use pointed spar of square magnesian stone goodly at coloured metallurgy furnace, to calcine cement...
The quality that improves fireproof data and add high grade variety, must become a basis with corresponding engineering technology and equipment, should be opposite above all currently quality of product of enterprise interior sale rises, efficiency of newer breed, play, fall the craft of the respect such as low consumption, safe environmental protection undertakes update and be transforminged, backward manufacturing technology and equipment should fall into disuse...
The production that vitreous frit kiln uses firebrick and equipment of furnace of other type kiln have essential distinction with the production of firebrick, its distinction depends on former have two characteristics: One, its are main the size of type product is very large, make produce a technology to complication greatly; <spanstyle= "font-size:14px;" . . .
Cement kiln is firing belt damage more easily than other position with firebrick, for the operation that kiln furnace stabilizes for a long time, must use the brick with higher quality. Be in some earlier year, the cement kiln of some clients is firing belt use the argillaceous brick with aluminous inferior content, in firing begin phase, bricky attaint is particularly apparent, service life is taken greatly...
The production that vitreous frit kiln uses fireproof data and equipment of furnace of other type kiln have essential distinction with the production of fireproof material, its distinction depends on former have two characteristics, 1, its are main the size of type product is very large, make produce a technology to complication greatly. 2, must satisfy the requirement with vitreous particularly strict to fireproof material quality industry. Frit...
Adiabatic firebrick is porosity can achieve 40%-85% , bulk density is low. Adiabatic firebrick call his light simple fireproof stuff again, have fireproof fiber blanket and its other because of what its include a few fireproof fiber. The character of adiabatic firebrick is porosity tall, heat conduction rate is low, use as commonly of kiln furnace outer place, can reduce kiln...
