Description
Technical field
The present invention relates to technical field of fire-resistant material preparation, particularly relate to a kind of heating furnace partition wall hanger brick castable.
Background technique
Heating furnace partition wall hanger brick generallys use high alumina castable and is made at present, due to heating furnace partition wall hanger brick
It is chronically in the environment of hot and cold alternation variation in use, it is desirable that it has excellent thermal shock resistance；Simultaneously because
Hanger brick itself design feature, it is desirable that it is with lower bulk density and sufficiently high intensity, to prevent in its use process
Phenomenon of rupture occurs.
Heating furnace partition wall hanger brick service life traditional at present is mostly or so half a year, frequently replaces hanger brick shadow in this way
Rhythm of production is rung, while also will increase the consumption of refractory material, leads to that the production cost increases.
Summary of the invention
The present invention proposes a kind of heating furnace partition wall hanger brick castable, solve the strength of materials in the prior art it is poor, use
Service life short problem.
The technical scheme of the present invention is realized as follows:
A kind of heating furnace partition wall hanger brick castable, is made of the raw material of following weight parts: 20~50 parts of light-weight mullite,
30~60 parts of mullite, 1~20 part of cement, 1~10 part of swelling agent and 0.1~0.2 part of water-reducing agent.
Preferably, conventional lightweight mullite or spherical lightweight that the light-weight mullite is 1~5 millimeter of partial size do not come
Stone.
Preferably, the mullite is the fused mullite or electricity of 0.088~1 millimeter of partial size, aluminium content greater than 60%
Molten mullite.
Preferably, the cement is 71 cement or 70 cement of the partial size less than 0.088 millimeter.
Preferably, the swelling agent is silica flour of the partial size less than 0.088 millimeter or aquamaine mountain flour.
Preferably, the water-reducing agent is sodium tripolyphosphate or calgon of the partial size less than 0.5 millimeter.
The above-mentioned light-weight mullite prepared in raw material and mullite are the materials with porous structure and hollow structure, by
In itself have good thermal shock resistance, product obtained not only body is close low and also thermal shock resistance more preferably.
The above-mentioned swelling agent silica flour prepared in raw material has phase transition process, the meeting in phase transition process with the variation of temperature
Certain expansion is generated, mullite can be formed with the aluminium oxide in other raw materials at high temperature, also can in this process
Certain volume expansion is generated, thus to offset the contraction of material.
The above-mentioned swelling agent aquamaine mountain flour prepared in raw material can be decomposed into mullite at high temperature, generate primary permanent swollen
It is swollen, the refractoriness under load and compressive resistance of product can be improved using this characteristic, are improved line after product is burnt and are changed, it is indefinite to eliminate
The contraction crack that shape refractory material generates in high temperature and cooling procedure.
The invention has the benefit that
The present invention adds reasonable expanding material by using mullite as primary raw material, makes hanging obtained
Brick product have the characteristics that bulk density is moderate, thermal shock resistance is excellent, volume stability is good, long service life, and service life can
Up to 1 year or more.
It can be improved the overall stability of material by adding swelling agent, material can be improved using pure calcium aluminate cement
Intensity, and then improve the service life of material.
