Wearability is fireproof material resists of the hard stock, gas that contain dirt wear away the ability of action. We are right the choice of fireproof material, its wear-resisting function is among them a main index. Be aimed at the environment with industrial kiln complex furnace, wait for equipment like room of carbonization of blast furnace shaft, anxious furnace, we choose fireproof material to need to be selected somewhat to its wear-resisting function.
Of fireproof material divisional have finalize the design fireproof material and adventitious fireproof material. We understand the wear-resisting nature of fireproof material from this two respects.
One, wear-resisting firebrick
The wearability of firebrick and temperature are concerned, some firebrick are like tall aluminous brick, think it is below constant temperature commonly (900 ℃ of 700 ℃ ～ are the following) , temperature jumps over tall wearability to heal low, can think to become what after temperature rises, as firebrick flexibility the model measures to increase, wearability is reduced somewhat.
Lift when temperature, after the great value that reachs stretch model capacity, reduce along with what stretch model measures, wearability rises somewhat instead. If argillaceous brick is when 1350 ℃ of 1200 ～ , wearability even excel normal temperature person.
Rise further when temperature, when amounting to 1400 ℃ above reduce quickly because of the fluid photograph viscosity in refractory products, wearability is reduced subsequently. If some firebrick contain chromic qualitative firebrick, lift along with temperature, wearability increases.
The chemical structure of firebrick is very old to the influence of its wearability, the mineral crystal hardness that bricky body comprises is tall, its wearability is taller. Below a few circumstances, the wear-resisting of firebrick is spent also matter with the bulk density of bricky body or porosity, density exceeds tall wear-resisting performance also with respect to it may not be a bad idea.
2, wear-resisting is fireproof and pouring makings
Wear-resisting is fireproof and pouring expecting is a kind of cement radical mortar of powder of compound odd constituent, by excel in cement, mineral sophisticate aggregate of makings, high strenth and fight crack wear-resisting agent, be made up via industrialized production and become.
Have wear-resisting loss small, intensity random of tall, appearance sex of controallable, whole strong, construction performance of simple, construction is good, because mix high polymer polymer, make felt of concrete of its basic level firm.
Wear-resisting is fireproof and pouring the advantage of makings:
1. Oxidation calcic content is inferior, can decrease those who generate is low in all frit photograph, rose thereby fireproof degree, high temperature intensity and the sex that fight broken bits;
2. Heat roast when the problem that nonexistent many hydration bolts in destroy and making, lukewarm intensity drops, as heat treatment temperature rise, intensity also rises;
3. Water requirement is reduced greatly, porosity is low, bulk density is high.
Wear-resisting is fireproof and pouring makings is main wait for an industry with Yu Ye gold, electric power, coloured, petrifaction, building materials.
Overspread cooling machine front to wait like wicket of around of kiln of bottom land of vitreous kiln stannum, cement high temperature resistant canal of coal of mouth of kiln of place, around, gush; All sorts of heat treatment furnace such as furnace of heating furnace, soaking; Liner of the liner of high temperature wear-resisting of reactor of liner of furnace of intermediate frequency induction, petro-chemical catalytic cracking, kiln of other industry furnace. Can use the site pouring, daub and beat hit construction way.
Accordingly, choose when us when fireproof material applies in all sorts of industrial kiln furnace, ask not only of fireproof product fireproof spend and high temperature resistant degree, spend to its wear-resisting also have a demand likewise.
