Description
Technical field
The present invention relates to casting technology field, more particularly to a kind of blast furnace cylinder iron cooling wall casting process.
Background technology
Rib type refractory brick is inlayed casting by blast furnace rib type heat edge brick cooling wall design requirement in casting process
Enter to cool down wall surface, to ensure cooling wall service life, edge brick is entered not in built-in metal device is used in casting die cavity
Row is fixed.And if edge brick can not be fixedly secured in cooling wall casting die cavity, in molten iron buoyancy and molten iron during casting and pouring
Edge brick will produce drift, float in the presence of the factor such as washing away, and when situation is serious cooling wall casting will be caused to scrap.
The Chinese patent of Application No. 201610964629.7 discloses a kind of " the anti-floating type heat edge brick of uplift pile and its moulding
Heat edge brick, is fixed in sand mold, realized to high temperature iron by method ", its uplift pile of heat edge brick provided with one by uplift pile
Water protecting against shock, LP blades and the anti-floating anti-function of pulling out, it is to avoid and solve the problem of heat edge brick loosens floating.But what it was used
It is the refractory brick of special construction, because the section of uplift pile on refractory brick is more than edge brick section, so as to add the system of refractory brick
Make difficulty and cost；In addition, after cooling wall casting, uplift pile protrudes from cooling wall surface, is applied being actually used in blast furnace furnace wall
Man-hour, not only can not as described in it " after blast furnace grouting, uplift pile again anchors grout blanket, makes body of heater more sturdy and durable ",
Because the gap very little on the inside of blast furnace between refractory brick and cooling wall, due to the presence of uplift pile, can largely effect on cast on the contrary
The mobility of material, causes to pour into a mould the integrated poured Quality Down of the bed of material, will so as to cause blast furnace furnace wall structure not reach construction production
Ask；Therefore, its technical scheme is not widely applied.
The content of the invention
The invention provides a kind of casting process of blast furnace cylinder iron cooling wall, using frustum type core facing as edge brick
When uplift pile, play a part of preventing that edge brick from floating drift in casting process；The frustum type core after cooling wall cast molding
Cleaned out with molding sand, cooling wall is still smooth surface with edge brick adjacent surface, ensure that the casting quality and height of the cast bed of material
The integral construction quality of stove furnace wall.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of fixing means of blast furnace hot edge brick when cylinder iron cooling wall is cast, the cast iron muscle of the cast-iron cooling wall side
Plate is arranged with edge brick in striped stride, cast iron and edge brick flush with outer surface；The fixing means of heat edge brick comprises the following steps：
1) self-hardening resin sand molding is used when cooling wall is cast；Cooling wall body wooden model is made first, in cooling wall body
In wooden model brick-inlaid groove is produced by edge brick size；Inlay brick both sides band tapered, brick big end side is inlayed when being put into brick-inlaid groove
It is inwardly mounted in brick-inlaid groove, edge brick small end is exposed surface；
2) a cone table core is bonded with viscous core cream by placed in the middle on the exposed surface for inlaying brick small end, cone table core is used
Self-hardening resin sand makes；Cone table core and the sideline of edge brick toe contact one side and the distance in edge brick small end each sideline for 15~
20mm, each side of cone table core has outward-dipping 5~8mm gradient along overhanging direction, is highly 40~50mm；Cone table
Core is dry, stand-by after bonding；
3) the edge brick for being bonded with cone table core is bumped into the brick-inlaid groove in cooling wall body wooden model；
4) cooling wall sand mold is made according to conventional self-hardening resin sand making technique, checks that edge brick is engaged with sand mold after molding
Whether face, cone table core and sand mold composition surface are seamless bonding fixation, are tamped, cemented with viscous core cream if any loosening；
5) according to conventional sand casting process cast, shake out, cleaning, cone table core is removed simultaneously during cleaning molding sand, is obtained
Obtain cast-iron cooling wall.
Compared with prior art, the beneficial effects of the invention are as follows：
Using interim uplift pile of the frustum type core as edge brick, play prevents that inlaying brick floats what is drifted about in casting process
Effect；Frustum type core is cleaned out with molding sand after cooling wall cast molding, and cooling wall is still smooth table with edge brick adjacent surface
Face, ensure that the casting quality of the cast bed of material and the integral construction quality of blast furnace furnace wall.

Embodiment
The embodiment to the present invention is described further below in conjunction with the accompanying drawings：
The fixing means of a kind of blast furnace of the present invention hot edge brick when cylinder iron cooling wall is cast, as shown in figure 5, the casting
The cast iron gusset of the side of iron cooling wall 5 is arranged with edge brick 1 in striped stride, cast iron and the edge flush with outer surface of brick 1；Heat inlays consolidating for brick
The method of determining comprises the following steps：
1) self-hardening resin sand molding is used when cooling wall is cast；Cooling wall body wooden model 3 is made first, in cooling wall body
In wooden model 3 brick-inlaid groove is produced by the edge size of brick 1；Inlay the both sides band of brick 1 tapered, brick 1 is inlayed when being put into brick-inlaid groove and is held greatly
Side is inwardly mounted in brick-inlaid groove, and edge brick 1 small end is exposed surface；
2) a cone table core 2, cone table core 2 are bonded with viscous core cream by placed in the middle on the exposed surface for inlaying the small end of brick 1
Made using self-hardening resin sand；The sideline of cone table core 2 and the edge toe contact one side of brick 1 and the edge small end of brick 1 each sideline away from
From for 15~20mm, each side of cone table core 2 has outward-dipping 5~8mm gradient along overhanging direction, highly for 40~
50mm；Cone table core 2 is dry, stand-by after bonding；
3) the edge brick 1 for being bonded with cone table core 2 is bumped into the brick-inlaid groove in cooling wall body wooden model 3；
4) cooling wall sand mold 4 is made according to conventional self-hardening resin sand making technique, checks that edge brick 1 connects with sand mold 4 after molding
Whether conjunction face, cone table core 2 and the composition surface of sand mold 4 are seamless bonding fixation, are tamped, cemented with viscous core cream if any loosening；
5) according to conventional sand casting process cast, shake out, cleaning, cone table core 4 is removed simultaneously during cleaning molding sand, is obtained
Obtain cast-iron cooling wall 5.
The present invention will be bonded with and the cone table core 2 of molding sand same material under the conditions of self-hardening resin sand molding process
Edge brick 1, which is uniformly put into the brick-inlaid groove of cooling wall body wooden model 3, to be positioned, in sand mold, and edge brick 1 can be realized with the faying face of sand mold 4
Seamless combination, passes through the bonded complete inlay casting of cone table core 2 in sand mold 4, and edge brick 1 is fixedly secured in cooling wall casting
In die cavity, it is to avoid because cast causes the edge drift of brick 1 to produce cast-iron cooling wall waste product.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
