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 air hole in light qualitative firebrick is made through adding the light aggregate such as combustible, vesicant or hollow ball, stomatic size is larger. Light qualitative firebrick is to show porosity is tall, density is small (be less than the firebrick with 1300kg ／ M3) , low thermal conductance commonly, have the adiabatic sex with poriferous finer structure, because this also calls adiabatic firebrick. Light...
The main effect of light qualitative brick is heat preservation heat insolation, reduce bearing, specific what advantage and character are there? Detailed introduction looks please below. Light qualitative brick has what advantage to pledge the brick points to epispastic brick namely commonly gently, normal and indoor partition is to use this kind of firebrick, won't increase floor to load, and sound insulation effect pretty good! Intensity goods...
When pledging firebrick brick and blaze contact fireproof thermal insulation to produce craft to produce brick of brick of light qualitative fireproof heat preservation and the fireproof thermal insulation that blaze contacts gently, commonly used and the method that the method is bleb law and burn down addition agent. In expecting for Xiang Ni, infiltrate gas, have two kinds of methods: 1, first with mechanical method to suspension infiltrate inside fluid air, like that...
Liner of furnace of high temperature kiln is to use fireproof material to build by laying bricks or stones is built and be become, the temperature inside furnace of the kiln when moving is very high, why to want heat preservation heat insolation? Say simply even if can be economical. What is adiabatic? Can the data that block sluggish thermal current transmits, say to heat up insulating material again. Heat-insulating material cent reflexes material for porous material and heat two kinds. Former use data...

Intensity of compression of firebrick normal temperature (abbreviate is CCS) is the unit area that points to the material below normal temperature can susceptive great pressure. National level (GB ／ T5072, 1985) provided means of experiment of compression of compact firebrick normal temperature: Below normal temperature, with pressure testing machine the rate with the regulation, to the sample to load of set dimension, till sample ruptures...
Current, the production of adiabatic brick still is used extrusion and firing craft, form air hole thereby, use in order to achieve the density of a need and thermal conductivity firing craft, can control stomatic bulk strictly, assure its thermal conductivity thereby. Good adiabatic brick used hardwood sawdust, this kind of material is relatively rare, but after treating water, won't arise picture...
The term of service of hot-blast stove asks to achieve commonly 10 to 20 years, need firebrick bears the loading of self-prossessed generation is very big, consequently the requirement fights the phosphate with creep good performance to combine tall aluminium below loading of use high temperature fireproof. Pass function of long to all sorts of firebrick high temperature creep to compare. Silica brick department is mixed in 0.lMPa loading heat 1550...
Reductive furnace uses fireproof data reductive furnace is to use argillaceous firebrick to build furnace normally, regard heat preservation as the brick with light qualitative firebrick, heat preservation brick is outer it is asbestine board or aluminous siliceous cotton insulation material. But the brick that hold coal tub in the palm and brick of coal tub mouth are good use tall aluminous brick. Furnace vault can be built with build by laying bricks or stones of tall aluminous brick, also can use tamp of tall aluminous fireproof mud, the beard on roof spreads 50...
Light qualitative silica brick and the product that pledge diatomite brick is two kinds differ gently, raw material and surface color, different. Light qualitative silica brick pledges silica brick calls silicon qualitative adiabatic brick again gently. 2 oxidation silicon is in 91% above, bulk density is in under 1.2g/cm3 pledge gently fireproof. . .
Pledge Mo Laishi brick is gently with Molaishi (the expensive aluminous simple fireproof stuff that 3Al2O3 · 2SiO2) gives priority to brilliant photograph. General alumina content is in 65% ～ 75% between. Mineral composition divides Molaishi outside, contain alumina among them inferior person still contain a few glass photographs and Fang Shiying; to contain alumina taller person still contain a few corundum. Light qualitative Molaishi brick but...
According to GB/T11835-2007 " heat insulation reachs its goods with cliff cotton, mineral wool " standard, the level of surface of exterior quality requirement that sets conduit insulation material, the problem; eccentricity such as the bruise that does not allow occurrence influence later period to use, smear, damaged should not be more than 10%; normally for, structure of heat-insulating material of heat preservation of heat addition conduit basically includes...
