Abstract
The present invention relates to a kind of anticorrosive castable, the anticorrosive castable is mainly by mainly by one-level alumine, clay, quartz sand, magnesia, mullite, metaborate, amide-type cosolvent composition.Characterized in that, each raw material of anticorrosive castable is formed by following parts by weight：80 100 parts of one-level alumine, 50 80 parts of clay, 20 30 parts of quartz sand, 20 30 parts of magnesia, 10 15 parts of mullite, 10 15 parts of metaborate, 5 10 parts of amide-type cosolvent.Anticorrosive castable adhesion strength provided by the invention is more than 0.55Mpa, and unit interval corrosion depth is less than 0.09mm/a, and service life is more than 175 days, it is weak to acid, basic refractory effect, there is good corrosion resistance, manufacturing process is simple, and manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of anticorrosive castable.
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 function-stable, service life length, corrosion resistance
By force, the low anticorrosive castable of manufacturing cost.
To achieve the above object, the present invention provides following technical scheme：
A kind of anticorrosive castable, it is characterised in that the anticorrosive castable is mainly by one-level alumine, clay, quartz
Sand, magnesia, mullite, metaborate, amide-type cosolvent composition.
Preferably, each raw material of anticorrosive castable is formed by following parts by weight：One-level alumine 80-100 parts, stick
Native 50-80 parts, quartz sand 20-30 parts, magnesia 20-30 parts, mullite 10-15 parts, metaborate 10-15 parts, amide-type help
Solvent 5-10 parts.
Preferably, the amide-type cosolvent is urea or acetamide.
The present invention manufacture method be：1. one-level alumine, clay, quartz sand, magnesia, Mo Lai are weighed in proportion
Stone, metaborate, amide-type cosolvent；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 anticorrosive castable adhesion property provided by the invention is good, to acid, alkaline fire proofed wood
The effect of material is weak, there is good corrosion resistance, and manufacturing process is simple, and manufacturing cost is low, remarkable benefit.
