Abstract
A kind of anticracking furnace lining mould and use it to prepare the method for stove liner, on stove inwall, installation fixes the housing of mould to form liner space, the castable refractory that mixes is filled to form furnace lining in liner space, and the installing hole on the forward position housing that the furnace lining made solidifies inserts core in furnace lining, and the degree of depth that core inserts liner space is any, extracts the making that core can complete furnace lining after the volume stability of furnace lining out.Use Mold Making of the present invention monolithic lining out, not only can ensure discharge unnecessary moisture and steam smoothly in the baking temperature-rise period before furnace lining puts into operation, can also stove afterwards opening repeatedly, in furnace shutting down process, the unbalanced stresses that effective absorption furnace lining thermal expansion produces, makes furnace lining in special process requirement or the safe coefficient greatly improving operation when accident sharply rises (falling) temperature as stood.
Description
Technical field
The present invention relates to the flame unitary type furnace lining in stove field, specifically a kind of anticracking furnace lining mould and use it to prepare the method for stove liner.
Background technology
Now, the hot equipment furnace lining of increasing drum, cone shape and various non-standard shapes adopts loose refractory to make monolithic lining.Must first support template when making monolithic lining, castable being blunged or inserts curing molding in template after ramming mass liquid agitation.So contain a lot of moisture or liquid in the monolithic lining that loose refractory makes, such furnace lining has to pass through high-temperature baking, after driving the moisture added in construction and liquid out of furnace lining, furnace lining could use.But, in the process that baking temperature raises, water or liquid become steam along with temperature continues to raise and along with the sharply expansion of volume, form immense pressure in furnace lining inside and cause implosion, make just to be torn in the bake process of furnace lining before formally putting into operation to cause slump of bursting apart, this damage before putting into operation will make lining durability greatly shorten even thoroughly to be destroyed.
Summary of the invention
For solving monolithic lining of the prior art in baker process because liquid evaporation or the furnace lining that causes of volumetric expansion burst apart problem, the invention provides a kind of anticracking furnace lining mould and using it to prepare the method for stove liner.
The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of anticracking furnace lining mould, comprise and be combined with stove inwall the housing forming liner space, housing is provided with the installing hole that diameter is no more than 12mm, installing hole is provided with the core in partial insertion liner space, and the end that core inserts liner vacant terminal can any degree of depth between stove inwall and housing.
Spacing between described installing hole is 0.2-0.35 rice.
Use above-mentioned anticracking furnace lining mould to prepare the method for stove liner, comprise the following steps:
1) on stove inwall, installation fixes the housing of mould to form liner space;
2) in liner space, fill the castable refractory that mixes to form furnace lining, and the installing hole on the forward position housing that the furnace lining made solidifies inserts core in furnace lining, and core can not through furnace lining;
3) after the volume stability of furnace lining, the making that core can complete furnace lining is extracted out.
In the present invention, the shape of installing hole can have any shape, as triangle, circle or other shape; The shape of the stove installed as required uses multiple set of molds to install, to make to form the hemi-closure space that can be loaded castable refractory between mould and stove inwall; The tetra-pack of each die-face is wrapped with skeleton, and the linking seam between the working face of the entirety keeping all moulds to be formed by these skeletons is smooth closely knit.
In the present invention, core inserts the end of liner vacant terminal can any degree of depth between stove inwall and housing, that is the degree of depth in core insertion liner space can be any, its objective is extracting along with core, some blind holes are left interior being lining with, in baker process, baker heat can reach rapidly furnace lining deep by these blind holes, furnace lining internal liquid expanding volume can extend to these blind holes, liquid in furnace lining and moisture along blind hole to furnace lining by thermogenetic hot kinetic potential and steam overflow and make furnace lining release in surface, protection furnace lining is not torn damage by internal expansion pressure.
Beneficial effect: use Mold Making of the present invention monolithic lining out, not only can ensure discharge unnecessary moisture and steam smoothly in the baking temperature-rise period before furnace lining puts into operation, can also stove afterwards opening repeatedly, in furnace shutting down process, the unbalanced stresses that effective absorption furnace lining thermal expansion produces, makes furnace lining in special process requirement or the safe coefficient greatly improving operation when accident sharply rises (falling) temperature as stood.

Reference numeral: 1, housing, 2, installing hole, 3, core, 4, liner space, 5, stove inwall.
Detailed description of the invention
As shown in the figure, a kind of anticracking furnace lining mould, comprise the housing 1 being combined with stove inwall 5 and forming liner space 4, housing 1 is provided with the installing hole 2 that diameter is no more than 12mm, installing hole 2 is provided with the core 3 in partial insertion liner space 4, and the end that core 3 inserts liner space 4 end can any degree of depth between stove inwall 5 and housing 1.
Be more than basic embodiment of the present invention, can according to the profile of actual conditions designing mould to be applicable to various difform stove.
Consider the intensity that can not have influence on liner, the spacing between the installing hole 2 on described housing 1 is 0.2-0.35 rice, and the diameter of installing hole is no more than 12mm.
Use anticracking furnace lining mould described above to prepare the method for stove liner, comprise the following steps:
1) on stove inwall 5, installation fixes the housing 1 of mould to form liner space 4;
Select suitable mould according to the shape of stove, size and the thickness that will prepare furnace lining and assemble in practical operation;
2) in liner space 4, fill the castable refractory that mixes to form furnace lining, and the installing hole 2 on the forward position housing 1 that the furnace lining of making solidifies inserts core 3 in furnace lining, and core 3 can not through furnace lining, so that form blind hole in furnace lining;
3) after the volume stability of furnace lining, extract the making that core 3 can complete furnace lining out, then can carry out baker by mold removal.
