Abstract
The present invention relates to a kind of insulated pouring material, the insulated pouring material is mainly by bauxite, coal tar, aluminous refractory cement, calcium nitrate, rock wool, cosolvent composition.Characterized in that, each raw material of insulated pouring material is formed by following parts by weight：70 100 parts of bauxite, 20 30 parts of coal tar, 50 80 parts of aluminous refractory cement, 20 30 parts of calcium nitrate, 10 20 parts of rock wool, 5 10 parts of cosolvent.For insulated pouring material provided by the invention using bauxite, aluminous refractory cement as major ingredient, cost of material is low, effectively reduces the price of insulated pouring material, the rock wool resistance to elevated temperatures and heat-insulating property of addition are splendid, can play good insulation effect.
Description
Technical field
The present invention relates to a kind of insulated pouring material.
Background technology
Castable is the widest refractory material of current production and application, is used mainly as oven inner liner, castable one
As there is higher high-temperature stability, therefore be widely used in metallurgical industry kiln, electric power kiln, mechanical kiln or Thermal Equipment
In, the use environment of castable is very severe, and the service life of castable is not grown generally, thus the market demand of castable is very
Greatly.But the function of castable on the market is relatively simple, and species is also fewer, and price is higher, and service life is not grown, heat insulating ability
Bad it can cause substantial amounts of energy waste.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of manufacturing cost is low, good heat insulating and uses
The insulated pouring material of long lifespan.
To achieve the above object, the present invention provides following technical scheme：
A kind of insulated pouring material, it is characterised in that the insulated pouring material is mainly by bauxite, coal tar, aluminous refractory cement,
Calcium nitrate, rock wool, cosolvent composition.
Preferably, each raw material of insulated pouring material is formed by following parts by weight：Bauxite 70-100 parts, coal tar 20-30
Part, aluminous refractory cement 50-80 parts, calcium nitrate 20-30 parts, rock wool 10-20 parts, cosolvent 5-10 parts.
Preferably, the cosolvent refers to borax or KI.
Preferably, the bauxite aluminium-silicon ratio 2.6-3.0.
The present invention manufacture method be：1. bauxite is weighed in proportion, coal tar, aluminous refractory cement, calcium nitrate, rock
Cotton, cosolvent；2. all raw materials are added to crusher in crushing 20min together；3. the raw material in step 2 is added to powder together
Broken machine crushes 30min；4. the raw material in step 3 is added to ball mill fine grinding 15min together；5. the raw material in step 3 is added
Enter mixer stirring 10min and can obtain insulated pouring material.
The invention has the advantages that insulated pouring material provided by the invention makes using bauxite, aluminous refractory cement as major ingredient
The heat resistance for obtaining insulated pouring material has risen, and the rock wool resistance to elevated temperatures and heat-insulating property of addition are splendid, plays well
Insulation effect.Raw material sources used in the present invention are wide, price is low, and equipment needed for production is less, and technological process is simple, thus
Effectively reduce insulated pouring material manufacturing cost.
