The reason that fireproof material is eroded

The reason that fireproof material is eroded in environment of high temperature work is varied, basically include the following fields:
1.Chemistry erodes soda acid: Fireproof material can produce chemical reaction with acidity or basic material, bring about the destruction of material composition. For example, acidity slag can erode alkalescent firebrick. Oxidation erodes: In high temperature environment, oxygen the certain part in meeting and fireproof material (wait like carbon, silicon, aluminium) produce oxidation reaction, bring about data strength to drop.
2.Physics erodes thermal shock to destroy: Sharp change can bring about frequent temperature fireproof material interior produces thermal stress, cause thereby crackle and flake. Wear away and erode: Liquid of slag, metal or aeriform flow will be right machine of generation of fireproof material surface erodes and wear away, bring about material attenuates gradually and flake.
3.Melt content permeates permeate erode: Below high temperature, the metal of melt or slag are met infiltration is fireproof in the hole of material and break, refrigeration hind forms sclerotic content, cause damage of material interior structure. Deliquescent erode: Material of a few melt can dissolve the certain part in fireproof material, cause the corrosion of material and prediction of a person's luck in a given year.
4.Gas erodes carbide and silicon to change content to form: In the environment that contains carbon or silicon, gas experience and fireproof data reaction generate carbide or silicon changes thing, change the original character of material. Sulfide erodes: The certain part reaction in the sulfide gas experience below high temperature and fireproof material generates sulfide, bring about material to become fragile.
5.Structural blemish hole leads: When the hole rate of fireproof material is higher, aggressivity material is permeated more easily and destroy material interior structure. Bond invalidation: The bond in fireproof material falls in high temperature may invalidation, bring about the adhesion between material grain to drop, thereby intensity of abate material whole.
6.Operate the operation temperature with exorbitant condition: The design that exceeds fireproof material uses temperature to be able to accelerate its deterioration process. Undeserved maintenance and operation: If frequent urgent cold urgent hot operation, non-standard maintenance is mixed,use the attaint that waits to be able to quicken fireproof material.
Erode an element through understand and controlling these, can prolong the service life of fireproof material effectively. Choose relevant data, optimizing furnace kiln design, normative operation and regular care and maintenance is to avoid the significant step that with slow down fireproof material erodes.
