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.
Light qualitative Molaishi mechanical function of the brick by Al 2 O 3 /SiO 2 than mixing microstructure decides, especially content of Al 2 O 3 is the Mo Laishi brick of 68% , when 1300 ℃ bending strength amounts to 570MPa, rupture tenacity K Ic amounts to 5.7MPa.Nm, when all comparing normal temperature 1.6 times taller, this kind rises along with temperature
The manufacturing technology of fire magnesium chromic brick and general similar. Be in to eliminate a brick firing the expand and causes inattentive effect when the as a result of MgO and CrO, AlO or iron oxide reaction in the process generates pointed spar, also can use compound collective agglomeration makings makes magnesian chromic brick. In addition
Fireproof cement is used very simple, after adding water to mediate OK and sclerotic, do not need to add other bond commonly, can add a few fireproof aggregate and powdery makings. If pure if using fireproof cement, the meeting after high temperature produces not little crackle. General fireproof cement can be able to bear or endure
Choose 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, classics high pressure shapes, high temperature is firing. Common pledge the capable person that chooses adiabatic firebrick production has clay character gently tall aluminium is qualitative, qualitative tall
Fireproof and pouring makings. One kind adds certain amount by fireproof stock what bond makes is graininess with farinaceous material. Have higher liquidity, apply to with pouring the indeterminate form that means shapes is fireproof material. With other and indeterminate form fireproof data phase is compared, bond is contained with moisture
Fireproof cement function and its chemistry composition introduce fireproof cement to often show aluminous acerbity calcium is the cement of bases. Fireproof cement is indeterminate form fireproof material, especially the basic bond of pouring and fireproof material. Its chemistry is comprised basically is Al2O3 and CaO, some still is contained
1. should know to condense above all the concept of gender and setting time. Fireproof cement belongs to indeterminate form fireproof material, add water or fluid shape bond to mix after closing, agitate makings loses the property that touch denaturation or plasticity and is in caky condition to become gradually condense quality. Experience place of this one process
The standard norms dimension of firebrick has about a hundred kinds, if calculate again,go up different, on 1000 kinds none exaggerative also. National relative standard " chromic brick of YB/T 5011-2014 magnesium " in regulation: By raw material cent is direct union frit of magnesian chromic brick, report closes recombine of frit of magnesian chromic brick, report to written guarantee again
Fireproof cement uses fireproof cement use method very simple, after adding water to mediate OK and sclerotic, do not need to add other bond commonly, can add a few fireproof aggregate and powdery makings. If pure if using fireproof cement, the meeting after high temperature produces not little crackle. Usable
What is the character of firebrick? The character of firebrick is the quality that in showing firebrick is using a process, has and characteristic, include the field such as the firebrick wearability, sex that fight broken bits, impact resistance. Temperature of bate of our common firebrick bulk density, apparent pore rate, loading
Magnesian chromic brick basically is used at metallurgical industry, if build open-hearth furnace the finery outside roof, electric stove roof, furnace and all sorts of nonferrous metal smelting furnace. The high temperature place of wall of furnace of freeboard power electric stove uses founding magnesium chromic brick, the finery outside furnace is tall erode an area to use synthetic makings to make
Mo Laishi brick has corundum better high temperature strength, fight high temperature creep gender, heatproof shake sex and fight aggressivity. A kind of typical corundum - the manage of Mo Laishi brick changes function to be: Al2O385% , fe2O30.45% , apparent pore is led 19% , intensity of normal temperature compression is more than temperature of 55MPa loading bate
