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.
In circular fluid-bed boiler, the solid stock chroma inside circular fluid-bed boiler is coal fines boiler a few times to about a hundred times, mix as a result of the tall grain chroma inside boiler high moving wind speed, flue gas velocity of flow bigger, grain is thicker, make fireproof material gets of many solid stock erode ceaselessly wear away
The CaO in fastening firebrick about MgO-CaO easily to hydrate problem, obtained certain result through concerning antirust to apply.
Mo Laishi (Mullite) it is Al2O3-SiO2 n duality the binary compound that fastens middling to press next only stability to exist, chemical type is 3Al2O3-2SiO2, academic composition is: Al2O371.8% , siO228.2% . Natural Molaishi is more exiguous, the Molaishi that uses normally is to pass artificial compound, have agglomeration Mo Laishi and electric frit...
Industry of our country glass is main kiln of vitreous pool kiln have 12 kinds, be aimed at these 12 kinds of kiln today model do to summarize, every kinds of kiln characteristic and applicable circumstance:
In last few years fireproof data market nots allow hopeful, the depression of steely market also affects the demand of the development of fireproof data company and market directly.
Aggregate of aluminium magnesium brick uses one class alumina commonly, powdery makings uses pink of fancy and aluminous grog and noodles or vermicelli made from bean or sweet potato starch of one class magnesia, use tall modulus water glass to make bond, the microtherm processing of the classics after suppress is finished product namely. This brick is used on the bag of big, medium-sized steel of modular casting, its life is 60~90 commonly second.
Functional sex is repaired makings is main use at the special place such as converter, electric stove, finery and steel bag, like hearth, bag bottom, breathe freely brick, brick and slide brick, its technology requirement is easy spread out smooth, good agglomeration and intensity are advanced.
From 1993 since put into production, discover phenomenon of hole of occurrence henroost of the firebrick inside kiln for many times in the overhaul or red kiln accident. The surface is smooth and natural, among low, both sides is tall
Fireproof data limited company establishs furnace of kiln of Zhengzhou Rong Cheng at going up century 90 time, have right of administration of independent imports and exports, be located in below foot of a hill of fleabane of Central Plains hinterland, the churchyard of new close city of middle of Zheng little high speed, border Gansu sea, Beijing is wide two old trunk railway, traffic is very convenient
Adventitious fireproof data also says to come loose shape is fireproof material, be by reasonable grading graininess comprise with farinaceous stock and bond, do not shape and firing and what use directly is fireproof material.
Electric stove furnace lid is the spherical shape structure that contains electrode aperture and smoke evacuation aperture, outer shroud part says advocate furnace lid, intermediate part calls port the lid (call trigonometry the area again) , the furnace lid when feed a machine can removed. Technology of electric stove smelt is extremely sophisticated, use condition of trigonometry area prefabricated component is very slashing.
Heat preservation is pouring expect even if bulk density is inferior pouring makings, basic system is in closely 1.5 the left and right sides. Pouring makings contain air hole much, bulk density is low, coefficient of thermal conductivity is small, heat preservation effect is good.
