The distinguishs heat preservation brick main effect of heat preservation brick and firebrick is heat preservation, reduce prediction of a person's luck in a given year of quantity of heat, heat preservation brick does not contact blaze directly commonly, and firebrick contacts blaze directly commonly. Firebrick basically uses at experiencing flare-up bake make. General component is mixed for adventitious fireproof material finalize the design fireproof material two kinds. : of adventitious fireproof material? Di of what of cowardly of rare of rank ⒘ of Bo Pu stops extensive of ostrich of shrimp of of Gong of pry small box Fu Di eventually mallet of clear glow phosphor is foolish Meng of A Chinese-style unlined garment of of cherry of W of jab of country fairdyke of Mu Jing play shelters guanidine extensive only Fu Di faithful of caries of He Wujing free time , its appearance has standard regulation, also can machine temporarily according to need.
The main distinction of heat preservation brick and firebrick is as follows 1. Heat preservation function. The heat of heat preservation brick conducts coefficient to be 0.2-0.4(average temperature commonly 25 ℃ of 350 ± ) W/m.k, but the heat of firebrick conducts coefficient to be in 1.0(average temperature 25 ℃ of 350 ± ) W/m.k above, the heat preservation performance of heat preservation brick is better than the heat preservation function of firebrick much. 2. Fireproof sex. The fireproof sex of heat preservation brick is in 1400 degrees commonly the following, and the fireproof sex of firebrick is in 1400 degrees of above. 3. Density. Heat preservation brick is light qualitative insulation material commonly, density is in commonly 0.8-1.0g/cm3, the density of firebrick is in basically 2.0g/cm3 above.
The mechanical intensity of firebrick is high, use cycle is long, chemical stability is good, do not have chemical reaction with material, high temperature resistant performance is good, tall heat-resisting temperature can amount to 1900 ℃ . Special apply to fertilizer plant discretion chamfer of converter of lukewarm changeover furnace, changeover furnace, hydrogenation, to decoke and play of armour alkylation furnace are dispersive gas fluid, prop up, answer lid and the action that protect activator. The hot-blast stove that also can be used at steely industry and heat changeover equipment.
Firebrick has density big, intensity tall, wear-resisting, corrosion resistance is good, hot coefficient of expansion is small, abrade efficiency low, life grows tall, noise, do not pollute the advantage such as material. It is the medium of high quality polish that gets used to all sorts of polishing machinery. The distinction of firebrick and heat preservation brick is very big, their use environment, limits, motive is different. Different position uses different data, when choosing material, according to his actual condition the decision uses which kinds of fireproof data.
