Abstract
The invention discloses a forsterite refractory brick and relates to the technical field of refractory material manufacture. The forsterite refractory brick is prepared from the following raw materials in parts by weight: 70-80 parts of olivine sand, 15-25 parts of magnesium carbonate, 15-20 parts of magnesium oxide and 10-15 parts of paper pulp; the forsterite refractory brick is prepared by virtue of the steps of batching, mixing, blank forming, drying and firing. Compared with the prior art, the forsterite refractory brick is high in refractoriness under load, does not shrink at a high temperature and is good in thermal stability; the forsterite refractory brick is used as a lining material of a forging heating furnace and a cement kiln, and can be prevented from crack damage due to shrinkage at a high temperature; as a result, the service life of the linings of the forging heating furnace and the cement kiln can be prolonged.
Description
Technical field
The present invention relates to refractory materials manufacturing technology field, especially a kind of forsterite refractory brick of the liner for forge furnace and cement kiln.
Background technology
Refractory brick is called for short firebrick, the refractory materials be fired into coal clay or other refractory raw materials.Mostly at present conventional refractory brick is, with soft clay and flint clay grog, to prepare burden by certain granularity and ratio requirement, after shaping, drying, burns till under the high temperature of 1300 DEG C ~ 1400 DEG C.Because the refractoriness under load of this refractory brick is low, thermal stability is poor, and at high temperature produces contraction, and thermal conductivity is high; This refractory brick is used as the inner lining material of forge furnace and cement kiln, easily at high temperature produces and shrinks and occur that crackle damages, cause the work-ing life of liner short.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of forsterite refractory brick, poor to solve existing refractory brick thermal stability, as the inner lining material of forge furnace and cement kiln, easily at high temperature produce and shrink and occur that crackle damages, the problem that work-ing life is short.
In order to solve the problem, the technical solution used in the present invention is: this forsterite refractory brick, is made up of the raw material of following weight part: olivine sand 70 parts ~ 80 parts, 15 parts ~ 25 parts, magnesiumcarbonate, 15 parts ~ 20 parts, magnesium oxide, paper pulp 10 parts ~ 15 parts.
In above-mentioned forsterite refractory brick technical scheme, technical scheme can also be more specifically: described magnesium oxide is caustic-calcined magnesite.
Described peridotites, main component is the silicate of iron or magnesium, and simultaneously containing elements such as manganese, nickel, cobalts, crystal presents granular, is a kind of nesosilicate mineral, can be used as refractory materials.
Described magnesiumcarbonate is amorphous powder, stable in nontoxic, tasteless gas, can make thermal insulation, resistant to elevated temperatures fire-retardant heat-insulation material, and the additive of food, medicine, makeup, rubber, ink etc.
Described magnesium oxide is white or pale yellow powder, odorless, tasteless, nontoxic, has the general character of basic oxide, belongs to gelling material, and have extremely fireproof insulating property, can change crystal into through more than 1000 DEG C high temperature sinterings.
Described paper pulp take vegetable fibre as raw material, and through the fibrous material that different processing methods is obtained, the main component forming fiber in paper pulp is Mierocrystalline cellulose, also has hemicellulose, lignin, resin, pigment, pectin and ash in various degree to grade material in addition.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The present invention adopts olivine sand and magnesiumcarbonate to be main raw material, magnesium oxide and paper pulp are as bonding agent, the forsterite refractory brick refractoriness under load made is high, and at high temperature can not produce contraction, thermal conductivity is low, and thermal stability is good, as the inner lining material of forge furnace and cement kiln, can not produce under high temperature and shrink and occur that crackle damages, extend the liner work-ing life of forge furnace and cement kiln.
Embodiment
