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.
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:
Boiler of circular fluid-bed boiler, rubbish incinerator, large power plant moves in, the chamber of a stove or furnace and surface of liner of stock circulatory system bear for a long time charging of solid of high concentration loop erodes
Below reasonable liner construction, the choice of fireproof material is crucial. The research development that each place comes to in nearly 30 years with fireproof material obtained crucible hearth a lot of achievement. The BC-7S small Kong Tanzhuan that carbon pledges material is like Japanese NDK company, BC-SSR exceeds small Kong Tanzhuan
Light qualitative brick points to epispastic brick namely commonly, normal and indoor partition is to use this kind of brick, reduce floor effectively to load, and sound insulation effect pretty good! Intensity goods is chosen high grade board shape corundum, Molaishi is aggregate, with silicon line Shi Fu closes for matrix, buy particular kind additionally additive mixes refine with a few rare earth oxide
Concrete of general silicate cement cannot bear the working requirement of high temperature, in to hydrate process separate out oxyhydrogen dissolves calcium, oxidation turns into calcium below high temperature; The limestone that serves as aggregate suffers pyrolysis below high temperature, intensity is destroyed. Common concrete can be used at the place of 300 ℃ the following low temperature such as furnace foundation and chimney only. And fireproof concrete makes...
Method of requirement of the classification that this standard provided to vitreous frit kiln uses brick of low porosity clay, technology, experiment, examine regular, mark, pack, carry and keep in storage and qualitative most certificate,
Wear-resisting is pouring expect by excel in aggregate, pink is expected mineral additive is comprised, via optimizing recipe design, have wear-resisting loss the smallest, intensity is high
Those who manufacture technology is different make the structural presence of magnesian chromic material apparent difference, affect the performance of magnesian chromic brick then, for example, it is good to combine stability of thermal shock of magnesian chromic brick directly, electric frit recombine is magnesian of chromic brick fight aggressivity can strong, the function of half recombine magnesium chromic brick uprights at both between.
Irrigate steel to basically be aluminous carbon and slide of aluminous zirconium carbon with slide, the addition as breed steel output and the requirement that improve molten steel quality, process of molten steel smelt increases calcium to handle technology
Magnesian carbon brick is nod alkalescent oxide with Gao Rong magnesian (melting point 2800 ℃ ) and be invaded by slag hard the Gao Rong of embellish nods carbolic element material to serve as raw material, add all sorts of blame oxide additive. Do not burn carbon with what charcoal pledges bond is united in wedlock and become compound and fireproof material. Magnesian carbon brick basically uses at furnace of converter, alternating current arc, dc arc furnace inside...
