Abstract
The present invention relates to a kind of castable refractory, the castable refractory is mainly by calcium hexaluminate, portland slag cement, carborundum, potassium nitrate, gypsum, sodium salicylate, antimony oxide composition.Characterized in that, each raw material of castable refractory is formed by following parts by weight：80 100 parts of calcium hexaluminate, 80 100 parts of portland slag cement, 30 50 parts of carborundum, 20 30 parts of potassium nitrate, 20 30 parts of gypsum, 10 20 parts of sodium salicylate, 5 10 parts of antimony oxide.Castable refractory adhesion property provided by the invention is good, hot（200 DEG C of ＞）Firm time is less than 1780 seconds, and refractoriness is more than 1800 DEG C, and fire resistance is good, and manufacturing cost is low, service life length.
Description
Technical field
The present invention relates to a kind of castable refractory.
Background technology
Castable refractory can be according to material feeding damage and the situation that drops, implement the feed supplement of uniform large-area, also can be according to existing
Field concrete condition considers overall be replaced.Castable refractory is granular made of refractory substance and pulverulent material, because adding
Bonding agent and moisture, there is very big advantage in terms of activity, in construction, can be constructed with the method for cast, without lattice
Additional heat treatment, can the scene method that be poured into a mould, caused a sensation, made firm by ramming by its pouring molding.Castable refractory has following on the market
Several respects feature：Functional lability, density are low, fragile in high temperature environments, drop.As fiercer shock and rolling occurs
It is dynamic, it is easy to deform, damage.Construction is also cumbersome, not easy to operate.Service life is not grown, and corrosion resistance is weak, later period maintenance cost
It is big etc..
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, fire resistance is good, and use
The castable refractory of long lifespan.
To achieve the above object, the present invention provides following technical scheme：
A kind of castable refractory, it is characterised in that the castable refractory is mainly by calcium hexaluminate, portland slag cement, carbon
SiClx, potassium nitrate, gypsum, sodium salicylate, antimony oxide composition.
Preferably, each raw material of the castable refractory is formed by following parts by weight：Calcium hexaluminate 80-100 parts, slag silicate
Salt cement 80-100 parts, carborundum 30-50 parts, potassium nitrate 20-30 parts, gypsum 20-30 parts, sodium salicylate 10-20 parts, three oxidations
Two antimony 5-10 parts.
The present invention manufacture method be：1. calcium hexaluminate is weighed in proportion, portland slag cement, carborundum, potassium nitrate,
Gypsum, sodium salicylate, antimony oxide；2. all raw materials are added to crusher in crushing 20min together；3. by step 2
Raw material is added to pulverizer and crushes 30min together；4. the raw material in step 3 is added to ball mill fine grinding 15min together；5. will
Raw material in step 3 adds mixer stirring 10min and can obtain insulated pouring material.
The invention has the advantages that castable refractory adhesion property provided by the invention is good, manufacturing cost is low, fire resistance
It is good, and service life is grown, remarkable benefit.
