Abstract
The invention relates to a baiting column of a submerged arc furnace and process for preparation, wherein the baiting column comprises an outer cylinder and an inner cylinder, which is characterized in that a connecting body which is provided with a cavity structure is made by the outer cylinder and the inner cylinder which adopt a casting method, the cavity is a water-cooled cavity, and an inlet and an outlet pipes which are arranged on the outer cylinder and both communicated with the water-cooled cavity. The invention adopts the heat-resisting alloy steel casting method to make the baiting column, the baiting column which takes carbon steel and heat-resisting alloy steel as raw material is integrated into a whole, a fabrication hole is welded after the casting process is finished. The invention reduces the opportunity of crack and ablation, and thereby service life of the baiting column is improved.
Description
Technical field
The present invention relates to hot stove blanking column in a kind of ore deposit and manufacture method thereof.
Background technology
Blanking column is that the hot stove in ore deposit is reinforced, the parts of cloth system, and its position is in around boiler face and the electrode.When equipment operation, be subjected to the high-temperature furnace gas effect, the ablated gradually loss of this cognition.In order to increase the service life, inside needs logical cooling water.
How soon existing blanking column adopts and is welded behind the steel plate forming, because the stress that forms when welding and steel plate forming is difficult to eliminate, causes under the high-temperature furnace gas environment very easily along weld cracking, leaks and scrap.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of weld cracking that prevents is provided, the hot stove blanking column in the ore deposit that increases the service life;
Another object of the present invention provides the manufacture method of the hot stove blanking column in above-mentioned ore deposit.
For achieving the above object, the present invention adopts following technical proposals:
The hot stove blanking column in a kind of ore deposit comprises urceolus and inner core, it is characterized in that: above-mentioned urceolus and inner core adopt casting method to make the connector with cavity structure, and described cavity is waterway, and inlet tube and outlet tube is located on the outer cylinder body, and all communicates with waterway;
Be provided with the confining tendon sheet in the described waterway;
The manufacture method of the hot stove blanking column in above-mentioned ore deposit, its technical process is:
A. according to the molding of blanking column shape, during molding the core consistent with the waterway structure put into model;
B. model and running gate system are put in the sandbox simultaneously, inserted molding sand, jolt ramming covers the sandbox top with plastic sheeting;
C. with vacuum pipe with the air emptying in the sandbox;
D. inject molten steel by running gate system, high-temperature molten steel gasifies model, and gas is discharged with vacuum, and molten steel occupies the position that model stays, after solidifying.
Above-mentioned model adopts polystyrene material to make, and core adopts resin sand to make.
The present invention adopts casting method to make blanking column, is that raw material is made an integral body with blanking column with carbon steel and heat-resisting alloy steel, treat that casting process is finished after, with the stifled weldering of fabrication hole.The present invention has reduced cracking and ablator meeting, thus the service life of having improved blanking column.

The specific embodiment
The hot stove blanking column in ore deposit of the present invention comprises urceolus 7 and inner core 8, urceolus 7 and inner core 8 are made the integrative-structure that leaves cavity structure each other by casting method, this cavity structure is the waterway 9 that feeds cooling water, be provided with some heat insulation muscle sheets 10 in the waterway 9, be used for increasing the cooling water flow backhaul, thereby improve cooling effect (as shown in Figure 5).Water inlet pipe 5 and outlet pipe 11 are located on the cylindrical shell 6, and they all communicate with waterway 9, feed cooling water by inlet tube and outlet tube, and the high temperature that produces that blanking column can be in operation is taken away.Also be provided with suspension hook 4 on the blanking column, during use, blanking column can be hung on 3 tops, hot stove furnace wall, ore deposit, blanking column 1 is distributed in (as shown in Figure 1) around the electrode 2.
The manufacture method of above-mentioned blanking column is:
A. according to the molding of blanking column shape, model 12 adopts the polystyrene material manufacturing, and polystyrene material is our usually said disappearance mould, and resin sand core 13 that will be consistent with the waterway structure during molding is put into wherein;
C. use vacuum pipe 18 with the air emptying in the sandbox 19;
Claims (4)
1. hot stove blanking column in ore deposit, comprise urceolus (7) and inner core (8), it is characterized in that: above-mentioned urceolus (7) and inner core (8) adopt casting method to make the connector with cavity structure, described cavity is waterway (9), inlet tube and outlet tube is located on the outer cylinder body, and all communicates with waterway (9).
2. by the hot stove blanking column in the described ore deposit of claim 1, it is characterized in that: be provided with confining tendon sheet (10) in the described waterway (9).
3. the manufacture method of the hot stove blanking column in ore deposit as claimed in claim 1, its technical process is:
A. according to the molding of blanking column shape, during molding the core consistent with the waterway structure put into model;
B. model and running gate system are put in the sandbox simultaneously, inserted molding sand, jolt ramming covers the sandbox top with plastic sheeting;
C. with vacuum pipe with the air emptying in the sandbox;
D. inject molten steel by running gate system, high-temperature molten steel occupies the position that model stays with model gasification back molten steel, after solidifying.
4. according to the manufacture method of the hot stove blanking column in the described ore deposit of claim 3, it is characterized in that: above-mentioned model adopts polystyrene material to make, and core adopts resin sand to make.
