Abstract
The present invention discloses a graphite refractory material, which is prepared from the following materials by weight: 20-25 parts of magnesium oxide, 35-40 parts of natural graphite powder, 6-8 parts of silicon carbide, 6-8 parts of sodium silicate, 30-40 parts of zirconium oxide, and 15 parts of a binding agent of a natural resin. The graphite refractory material has the advantages of good adhesion to avoid fall-off from the inner surface of a furnace, strong fire resistance, no crack at high temperature, good economical performance and high safety performance.
Description
Technical field
The present invention relates to burner hearth field of material technology, particularly relate to a kind of graphite refractory.
Technical background
Application to refractory is in the every field of the national economy such as iron and steel, non-ferrous metal, glass, cement, pottery, petrochemical industry, machinery, boiler, light industry, electric power, military project, be ensure above-mentioned industry production run and the requisite basic material of technical development, in hot industry production development, play irreplaceable vital role.Burner hearth is surrounded by furnace wall the solid space supplying fuel combustion, the effect of burner hearth ensures that fuel burns as much as possible, high temperature is produced in combustion processes, traditional material is bonded in surface of burner hearth, and its bonding is poor, is easy to come off, cause burner hearth Yin Gaowen after coming off and be out of shape, and the resistivity against fire of material is poor, easily cracks, affects it and normally use.
Summary of the invention
For solving above-mentioned Problems existing, the invention provides a kind of cohesiveness good, being bonded in burner hearth internal surface difficult drop-off, resistivity against fire is strong, can not crack, good economy performance, the graphite refractory that safety performance is high while high temperature.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of graphite refractory, is made up of the material of following mass fraction:
Magnesium oxide 20-25 part
Natural graphite powder 35-40 part
Silicon carbide 6-8 part
Water glass 6-8 part
Zirconium white 30-40 part
Bonding agent 15 parts.
Preferably, above-mentioned graphite refractory, described bonding agent is natural resin.
The beneficial effect that technical solution problem of the present invention is brought is: cohesiveness of the present invention is good, is bonded in burner hearth internal surface difficult drop-off, and resistivity against fire is strong, and can not crack while high temperature, good economy performance, safety performance is high.
