Technical Field
The utility model belongs to the technical field of converter vaporization cooling flue, specifically speaking is a converter feed opening device.
Background
The feeding hole device is mainly used for adding auxiliary raw materials in the steelmaking process, is arranged on a movable section of a converter vaporization flue, and is generally arranged in two positions which are respectively arranged at two sides of the flue. The feed opening device is positioned in a high-temperature area of converter flue gas and needs cooling water for cooling. In the using process, two main reasons for failure of the feed opening device are provided, one is that cracks are generated and spread at the welding seam under periodic alternating thermal stress, and the welding seam is pulled to crack and leak water. The other is that the chute wall is abraded and thinned by the material during the process of smoke dust scouring and blanking until water leakage occurs. The general feed opening can only use 3 months and will lose efficacy, must repair, seriously influence the efficiency of steel mill, cause great loss.
The feed opening device in the prior art has two forms. The first is that seamless pipes with the same diameter are arranged together along the circumferential direction to form a barrel shape surrounded by pipes, the water supply is directly communicated to a lower opening ring pipe by a seamless pipe with a slightly larger diameter, the cooling water is distributed to each heating pipe through the ring pipe and then collected to an upper opening ring pipe, and the return water is led out by the upper opening ring pipe. The dense-row pipe type chute is characterized in that a plurality of intermittent wear-resistant strips are welded on the heated pipe on the inner wall, and when the bulk material slides downwards in the chute, the wear-resistant strips are washed to avoid directly washing and rubbing the pipe wall, so that the effect of avoiding abrasion is achieved. The second structure is a water tank type structure with a partition plate inside, cooling water flows and cools between the layered partition plates, and meanwhile, intermittent wear-resistant strips are welded on the inner wall, so that the abrasion of the inner wall of the water tank during blanking is reduced.
In order to prolong the service life of the feed opening device and reduce the loss caused by the failure of the feed opening, a layer of shroud plate is adhered to the inner wall of the feed opening in the prior art so as to improve the wear resistance of the feed opening, but the cost is higher in the mode. And in the other structure, all the pipe bodies are made into castings, the structure abandons a water cooling form, has no abutted seam, is slightly influenced in alternating thermal stress, but has higher cost and can not meet the requirements of all manufacturers.
SUMMERY OF THE UTILITY MODEL
For solving exist among the prior art more than not enough, the utility model aims at providing a converter feed opening device to reach wearing resistance, high temperature resistance, reduction in production cost, the purpose that improves life of reinforcing feed opening device.
In order to achieve the above object, the utility model adopts the following technical scheme:
a converter feed opening device comprises an inner sleeve and an outer sleeve sleeved outside the inner sleeve, wherein a cavity between the inner sleeve and the outer sleeve forms a cooling water tank, two ends of the cooling water tank are arranged in a sealing mode, and one end face of the cooling water tank is an inclined plane; the cooling water tank comprises an upper half cooling water tank and a lower half cooling water tank which are fixedly connected in a split mode, the upper half cooling water tank is the end without the inclined surface, the lower half cooling water tank is the end with the inclined surface, and the lower half cooling water tank is a casting; the corresponding positions in the upper half cooling water tank and the lower half cooling water tank are respectively and fixedly provided with a partition plate for forming a water channel, and the outer sleeve is provided with a water inlet and a water outlet.
As to the utility model limit: the inner sleeve part of the upper half cooling water tank is a cylinder, the outer sleeve part of the upper half cooling water tank is arc-shaped plates which are spliced with each other, and the outer walls of the arc-shaped plates, the partition plates and the inner sleeve are fixed with each other.
As a further limitation to the present invention: the partition plates are arranged at intervals, and the two ends of the cooling water tank are communicated in an annular mode.
As another limitation to the present invention: and the water inlet and the water outlet are both arranged at the position of the upper half cooling water tank close to the end surface.
Since the technical scheme is used, compared with the prior art, the utility model, the beneficial effect who gains lies in:
(1) the lower half cooling water tank of the utility model comprises one end provided with an inclined plane, and is integrally a casting, because the part is positioned inside the flue in the converter, and is eroded by corrosive gas for a long time, and is positioned in a high-temperature environment during working, the lower half cooling water tank adopts a casting form, thereby increasing the high temperature resistance and the corrosion resistance, reducing the damage degree of the lower half cooling water tank, prolonging the service cycle, and the upper half cooling water tank is less corroded and less impacted relative to the lower half cooling water tank, and the common water tank form is adopted, thereby saving the production cost;
(2) the outer sleeve of the upper half cooling water tank of the utility model is formed by splicing arc plates, which can effectively utilize leftovers or materials with smaller area and save production cost;
(3) the partition plates of the utility model are arranged at intervals, and the two ends are annular passages, so that the cooling water can circulate more generally, the circulating path is longer, and the cooling effect is better;
(4) the utility model discloses a water inlet and delivery port are all located the position that first cooling water tank is close to the terminal surface, make the cooling water when entering into cooling water tank, absorb the heat and slowly heat up, can not make cooling water tank because the crackle of supercooling suddenly.
To sum up, the utility model discloses a cooling is effectual, and wearability and impact resistance are good, practice thrift manufacturing cost, long service life, high temperature resistant is effectual, is applicable to all feed openings devices.
