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 quality that bibulous rate is the water that all open pore place in pointing to poriferous body absorb is as dry as its the ratio of the quality of material. In actual production, bibulous rate often is used to the quality of to calcine of appraisal raw material, of to calcine better, bibulous rate numerical value is lower. Zhengzhou flourish fills kiln furnace fireproof data limited company, produce brick of one class heat preservation, all sorts of protecting...
Sticking earthy and adiabatic brick is the Al203 content that controls for main raw material with saggar the adiabatic and refractory products that is 48%-55% . Its produce craft to add content law and bubble way with burn oneself out. With saggar, float bead, saggar grog makes raw material, mix into is added bond and curium wood chip, classics burden, mix, shape, dry, firing, make...
20 centuries 80 time evening, begin to study the composite material of binary department and even oxide of 3 yuan of oxide in the department and blame on international. Zhong Xiangchong academician thinks: Oxide and blame oxide composite material are a when technology of domestic and international fireproof material develops new century important way, predict it develops likely make burgeoning Zuo property fireproof...
Company of furnace of a lot of kiln can use phosphatic brick, need almost every year to purchase a batch of phosphate bricks, the personnel that the company is in charge of purchasing fireproof material believes to be able to have certain knowledge to phosphatic brick, but the is phosphatic brick commonly character of understanding, for instance phosphatic brick fights thermal shock function temperature of bate of good, loading, these...
Because static load is caused below normal temperature condition,the problem that fireproof data appears is rarely. Because this undertakes this kind of experiment is to consider indirect ground normally,examine other property, be like wearability. Be like compression intensity again under 1000 pounds / inch the chromic magnesia brick of 2, faint from a place in workshop of a fusion merely another place appears easily...
The heat of the chromite in heat preservation brick expands to be in 850 degrees about: Above increases significantly, produce systole again to high temperature, present quick systole from 1500 ° C about. Because chromite is OK,solid fuse-element absorbs MgO, the result is met bend | Crystal lattice expands since, that is to say, when MgO is added to heat in chromite, what can eliminate it is firing and contractive, accordingly...
Fireproof mud uses appropriate build by laying bricks or stones to build wall of path of the flue of kiln furnace, kiln, kiln and fire box, this makes the cost that we can reduce build by laying bricks or stones to build kiln furnace greatly. When making fireproof mashed vegetable or fruit, expect pink beforehand wet, make water saturated, next, mix carefully in fireproof mud blender. Be able to bear or endure in perfusion pattern is used when fireclay, fireproof mud uses air hammer method...
The pink of heat preservation brick can get the grain of requirement measure qualification after makings screening, but cannot make all particle size just the same, can acquire the grain inside some area only, although be in the grain inside an area, also can have a few upper limit that are more than a requirement and the floor level that are less than a requirement, enter lay aside to expect accumulation process produces the warehouse when stock...
Of blast furnace send wind to raise a canal to be located in sirocco conduit rear, it is the conduit is defeated by wind between join blast furnace, say its send wind to raise a canal for blast furnace commonly. Its action sends sirocco into blast furnace namely inside, OK still to furnace gush fuel. Its working environment cans be imagined, because carry sirocco all the time, if working hours became long, temperature can last...
The basic characteristic with fireproof firing material is, should have above all taller than other silicate industry firing temperature, and according to material property different, have the heat preservation time that comparative even. As a result of above characteristic, fireproof material is firing on exercise using up a large number of high grade soft coal every year. Special in iron and steel industry flying development is badly in need of high grade...
Fireproof and pouring the beneficial result that the quality stand or fall of makings follows a company has immediate concern, what all clients hope he are bought is pouring service life of makings quality qualification is long, such not only to oneself the company saved expenses of one share fund, and improved manufacturing efficiency. So what how let oneself buy is fireproof and pouring expect service life grows...
We had understood, in steely production technology, although still existing,a lot of oxygen cent press lower exercise case, but contain carbon fireproof material can all-pervading reason is its have the stress that the heat that absorbs high temperature to fall changes and arises, the cause that prevents the main character that the fireproof stuff place such as melt metal or slag soak asks...
