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 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...
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...
Small today the relevant introduction that those who write everybody introduction is adiabatic firebrick, the hope is right of company of the furnace that construct pit purchase help somewhat. One, light qualitative adiabatic firebrick. Use organic matter to make bricky porosity increases. The economic interest of the life of furnace of the locomotive rate that pledges the quality of adiabatic brick matters to kiln furnace directly gently, kiln and its company. 2, ...
The client is being bought fireproof and pouring what look surely when makings is fireproof and pouring the compression intensity of makings, choose actually high grade fireproof and pouring makings the compression strength that does not see its only only, also want to see its tenacity at the same time. Because fireproof and pouring the tenacity of makings is to control its to appear the most efficient way of crackle. So how to let fireproof and pouring the tenacity of makings increases...
In the process of fireproof material production of firebrick etc, often can produce solid photograph -- the transition process of solid photograph. This kind of change is the process that crystal transforms to another kind of structure by a kind of structure, common in silicate firebrick. Have so a concept, if,crystal is in inside constant temperature limits the free enthalpy lowest of a kind of structure...
For mineralization stronger, join ferric oxide toward the complement in lime. CaO-FeO-SiO2 system has melting point to be the most fusible fuse-element of 1105 Celsius, contain CaO11.5% , feO45.5% and SiO243.0% , with CaO:FEO=l1:3The scale conform to of.965 closes. Mineralizer and fluid photograph composition still can be used make quartz extraction like the scales of a fish crystal is connected...
