Why brick of anxious furnace furnace door from cast-iron changed firebrick?

Brick of anxious furnace furnace door from cast-iron the main reason that changes firebrick includes:
Fireproof performance is better: Firebrick has good fireproof sex to be able to be mixed high temperature resistant function, can bear the astringent condition below environment of anxious furnace high temperature, not easy damaged and be out of shape.
Fight erode ability strong: High temperature of existence of anxious furnace interior, caustic gas and chemical material, brick of cast-iron furnace door is eroded easily and damaged, and firebrick is had stronger fight erode ability, can resist better of these caustic material erode.
Better sealed performance: Firebrick can hold the sealed property of anxious furnace furnace door better, reduce the gas inside furnace and caloric prediction of a person's luck in a given year, the sources of energy that is helpful for raising Jiao Lu uses efficiency.
Longer service life: Compare brick of cast-iron furnace door, firebrick has longer service life, can reduce furnace door to change frequency, decrease defend cost and manufacturing machine down time.
Environmental protection performance is better: Use firebrick can reduce the use of cast-iron material, reduce pair of rich thereby use up, accord with environmental protection and the demand that can expand continuously.
The place on put together is narrated, brick of furnace door of will anxious furnace from cast-iron the fireproof property that changes firebrick to be able to raise furnace door, fight erode ability and sealed performance, prolong service life, also have better environmental protection performance at the same time, it is a when anxious heat technique improves important facet accordingly.
