Description

A kind of preparation method that refractory brick is prepared using isostatic pressing mode
Technical field
The invention belongs to fire resisting material field, and in particular to a kind of preparation that refractory brick is prepared using isostatic pressing mode Method.
Background technology
Compared to traditional molding mode, the product structure that equal pressing forming technology obtains is uniform, and inside is without gross blow hole or gas The defects of bubble, can take into account erosion-resisting characteristics and thermal shock resistance；Meanwhile the technology can prepare large-sized product, meet Build the requirement of brickwork joint by laying bricks or stones to refractory brick large scale, reduction in Special use position.
The key of equal pressing forming technology is the preparation of pug, on the one hand requires the moisture content of pug uniformly and is maintained at To ensure that pug has preferable mobility and shaping finished product rate in relatively low scope；On the other hand pug is required to have higher Bond strength is to ensure that molding blank has enough intensity；In order to ensure pug performance, existing isostatic pressing pug system Standby mode is as follows：It will first be kneaded together with refractory aggregate, matrix fine powder and more liquid binder, more liquid binder makes Refractory raw material fully soaks, and fine powder is equably wrapped on particles of aggregates under liquid binder effect, ensures that bonding agent is uniform It is distributed and enough adhesion strengths can be provided；Then, the pug being kneaded is spontaneously dried or heat drying, excludes liquid knot Unnecessary moisture in mixture, ensures that the moisture content in pug reaches forming requirements；In the drying process and will be to pug after drying The sequence of maneuvers such as it is stirred, overturns, to ensure the moisture content uniformity of each position pug；This method can obtain satisfaction will The pug asked, but pug moisture content and its equally distributed control process are complicated, it is not easy to operate；Meanwhile the cycle prepared by pug It is long, of high cost, influence the production efficiency and cost of product.
The content of the invention
The purpose of the present invention is to propose to a kind of preparation method that refractory brick is prepared using isostatic pressing mode, can lead to Cross improvement pug preparation process and solve the shortcomings that clay drying process is not easy to operate, the cycle is long in existing equal pressing forming technology, And there is easy to operate, high yield rate, prepared refractory brick has that size is big, even structure, and thermal shock resistance is excellent, corrosion resistance Can be good the characteristics of.
To achieve these goals, the technical solution that the present invention takes is as follows：
A kind of preparation method that refractory brick is prepared using isostatic pressing mode, the preparation method include raw material Composition, the preparation of pug and the preparation of refractory brick；It is comprised the following steps that：
1）The composition of raw material：The raw material composition and mass percent of refractory brick are that granularity is：The particulate material 45 of 0.1 ~ 3mm ~ 65%；The matrix fine powder 35 ~ 55% of granularity ＜ 0.044mm；The raw material is also outer added with bonding agent；The bonding agent includes Solid binder and water；The addition of the fixed knot mixture is the 0.8~1.5% of raw material weight, and the addition of water is raw material weight The 0.5~1.5% of amount；The solid binder is solid phosphoric acid aluminum dihydrogen；
2）The preparation of pug：By step 1）Described in particulate material and solid binder stirred in Mill with roller, make solid Bonding agent is evenly distributed in particulate material, and then adding water, mixed grind, water can fully soak aggregate and make solid binder together Aggregate surface is equably wrapped in after there is certain viscosity, finely dispersed solid binder to have viscosity after dissolving, finally Matrix fine powder mixed grind together is added, matrix fine powder is equably wrapped in the surface of particulate material under the action of bonding agent, obtain etc. Hydrostatic profile pug；
3）The preparation of refractory brick：By step 2）Prepared pug is directly loadable into mould, in isostatic pressing machine through 90~ The pressure forming of 180MPa, can obtain when 1550 DEG C~1650 DEG C insulations 8 are small after 120 DEG C of dry 24h needed for size it is resistance to Firebrick；The full-size of the refractory brick is：Long 1200mm, wide 600mm, high 500mm.
The addition of the solid binder is the 0.8 ~ 1.2% of raw material weight.
The addition of the water is the 0.5 ~ 1.2% of raw material weight.
The refractory brick is corundum brick or corundum-mullite or chrome corundum brick or high-chrome brick.
The particulate material is corundum in granules, the one or more in chrome oxide particle, mullite particle, pink fused alumina particle Combination.
The matrix fine powder is aluminum oxide fine powder, one or more of groups in chromium oxide fine powder, powdered zirconium oxide, clay Close.
A kind of preparation method that refractory brick is prepared using isostatic pressing mode proposed by the present invention, using separation principle, Bonding agent is sequentially added into the form of solid binder and water, both ensure that the wetability of bonding agent and water to raw material, It is set to be evenly distributed in pug；In turn ensure that does not have unnecessary moisture in pug, it is low to pug water content to meet shaping It is required that；Therefore, wetability is poor when which solves in traditional pug preparation process liquid binder very little, bonding agent distribution not Uniformly, problem of Cracking is molded caused by bonding agent adhesion strength is low etc.；It is more to turn avoid bonding agent addition in existing method When, to exclude the processing procedures such as drying for carrying out of excessive moisture, the manufacturing cycle and production cost of pug are substantially reduced, and With easy to operate, high yield rate, prepared refractory brick has that size is big, even structure, and thermal shock resistance is excellent, erosion-resisting characteristics The characteristics of good.
