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. What is intensity of temperature of bate of our common firebrick bulk density, apparent pore rate, loading, compression waits these a moment? These belong to firebrick from some attribute. 1, chemical composition: Bases decides this character of fireproof material and characteristic. 2, bulk density: Unit volume weight, density is big, explain compact sex is good, intensity is likely tall, but coefficient of thermal conductivity may be big. 3, apparent pore rate: Did not make particular demand, but must control apparent pore strictly as manufacturing manufacturer. 4, loading bate temperature: Also call high temperature loading to begin to be out of shape temperature, this parameter is very important, the counteractive ability with mark high temperature resistant material. 5, heatproof shake function: Fight the ability that temperature changes quickly and is not destroyed. 6, compressive strength: Bear (normal temperature) capacity of the greatest pressure. 7, fight lose strength: Bear the capacity that cuts pressure.
Firebrick chooses fireproof raw material, join fireproof pink makings and additive, bond to be become via mixing fire of the refine, high temperature after shaping, the fireproof material itself that the firebrick that make uses has certain property, form a kind of peculiar function via be being met after agglomeration of high temperature environment after union.
The character of firebrick:
1, low creep sex: Common firebrick does not ask when production creep is led commonly, ask when to the firebrick of low creep is made, need to control the fireproof raw material of firebrick, a future life of the technology that make produces firebrick. Low creep firebrick changes in the squirm below high temperature environment the gender is small, the change that the change that follows time below high temperature environment namely produces is little.
2, small air hole, the apparent pore rate of firebrick also is to detect an index that firebrick pledges whether whether compactly, gently, but low stomatic firebrick belongs to a kind of special firebrick, control raw material and manufacturing technology will complete the treatment of low stomatic firebrick, use at kiln furnace liner to build line to be able to prolong the service life of liner.
3, excel in wear-resisting, firebrick has excel in wearability, excel is general and commonly used firebrick, firebrick issues compression intensity in high temperature environment tall, wearability is good, be like carborundum of fireproof raw material, itself has certain wearability, the fireproof raw material that serves as firebrick can increase the wearability of firebrick.
4, thermal conductivity, the firebrick with good thermal conductivity passes thermal efficiency tall, if carbon pledges itself of fireproof raw material has certain thermal conductivity, the firebrick that use carbon pledges raw material is made has certain thermal conductivity.
Above at 4 o'clock illustrate the character of firebrick, firebrick makes from some attribute and character its develop the high temperature capability that firebrick has below high temperature environment, the liner that makes firebrick build by laying bricks or stones is built can resist the gas of high temperature is reached slaggy erode, better make kiln furnace moves.
