Description

Slag removal device for steelmaking converter platform

Technical Field

The invention relates to slag removing equipment, in particular to a slag removing device for a steelmaking converter platform.

Background

At present, a converter in the domestic metallurgical industry is taken as one of important steelmaking links, desiliconization, decarburization, heating and other processes are carried out in an oxygen lance oxygen supply mode, molten iron is converted into molten steel, and the main processes comprise scrap charging, iron charging, smelting, tapping, slag splashing, slag pouring, converter mouth maintenance and cleaning and the like. In the daily operation process, although the converter front platform is protected by a smoke baffle door, a part of scrap steel and residual iron and steel slag splashes in the smelting process fall to the converter front platform; secondly, when oxygen supply amount of the oxygen lance, lance position of the oxygen lance and addition of an auxiliary material coolant are not controlled properly in the smelting process of the converter, splashing can be generated, in order to prevent the splash between the smoke damper and the rail from being stuck by splashing slag steel, the smoke damper is opened when the converter splashes, and at the moment, a large amount of slag steel falls on a platform in front of the converter; thirdly, the cleaning of the converter mouth is a conventional operation, and the cleaned steel slag can fall to a platform in front of the converter, even large slag blocks.

The accumulation of the platform slag steel in front of the converter affects the environment on one hand and does not meet the requirement of green steelmaking; secondly, slag is accumulated on the smoke gate track, the smoke gate cannot be closed, and when the reaction in the converter is violent in the smelting process, the smoke of a factory building is easy to generate and is inconsistent with the requirements of an urban steel mill, and especially under the implementation of the current environmental protection method, the smoke gate is equivalent to unorganized discharge; and thirdly, potential safety hazards are brought, people walk insecurely, and engineering vehicles for auxiliary operation of the converter cannot pass through.

At present, most of the slag is manually cleaned, the bulk slag is cleaned by a forklift and the like, the efficiency is low, and the slag is generally cleaned for 2 to 3 times in one shift, and each time lasts for 10 to 15 min; secondly, there is the potential safety hazard in manual cleaning, especially when being close to converter edge, belongs to the high altitude and faces the limit operation, need wear the safety belt and can implement, and the activity duration is longer.

Disclosure of Invention

The invention aims to provide a slag removal device for a steelmaking converter platform, which has the advantages of high cleaning speed, safety, reliability and reduced labor intensity.

The utility model provides a steelmaking converter platform scarfing cinder device, includes backup pad and scarfing cinder brush mechanism, and the backup pad design is for linking to each other two sections, and one section is solid steel sheet, and another section is hollow square frame, and solid steel sheet and hollow square frame's junction is located to scarfing cinder brush mechanism, includes a mounting panel and sets firmly the steel brush on the mounting panel, and the mounting panel passes through the bolt fastening at solid steel sheet side tip, and steel brush installation direction is mutually perpendicular with solid steel sheet, and solid steel sheet opposite side tip still is equipped with a pair of jack that supplies fork truck male.

The length of the hollow grid frame is half of that of the solid steel plate.

The mounting plate is made of strip steel, and the steel wire brush is formed by welding steel wires at the bottom of the strip steel.

The length of the bar steel is less than the width of the solid steel plate, and the two ends of the bar steel are respectively provided with a solid steel plate side part

100mm。

The steel wire length be 200mm, and stretch out solid steel sheet bottom 100 mm.

By adopting the technical scheme of the invention, the invention has the following advantages:

1. the safety is ensured, and the manual cleaning of the overhead operation at the edge is eliminated;

2. the site environment is improved, the sanitation of a converter front platform is ensured, and the smoke of a factory building caused by the fact that a smoke door cannot be closed is avoided;

3. the workload of site environment cleaning personnel is greatly reduced;

4. the efficiency is improved, only 5min is needed once, and the production of logistics organization is facilitated;

5. the slag removal tool is convenient to maintain, small in occupied area, convenient to maintain and low in cost.

Detailed Description

The technical scheme of the invention is further explained by combining the drawings and the embodiment.

The slag removing device of the steelmaking converter platform comprises a supporting plate and a slag removing brush mechanism 3, wherein the supporting plate is designed to be connected with two sections, one section is a solid steel plate 1, the other section is a hollow square frame 2, the slag removing brush mechanism 3 is arranged at the joint of the solid steel plate 1 and the hollow square frame 2 and comprises a mounting plate 31 and a steel wire brush 32 fixedly arranged on the mounting plate 31, the mounting plate 31 is fixed at the side end part of the solid steel plate 1 through a bolt 33, the mounting direction of the steel wire brush 32 is vertical to the solid steel plate 1, and a pair of insertion holes 5 for inserting a forklift is arranged at the other side end part of the solid steel plate 1.

The method comprises the following specific steps: the hollow grid frame 2 occupies about 1/3 of the length of the whole slag removing device, the main purpose is to open holes to facilitate the slag removal, and the height is half of the thickness of the solid steel plate 1 to install the wire brush 32.

The solid steel plate 1 occupies about 2/3 of the whole slag removing device, and aims to ensure the gravity center and set a forklift driving point on the rear end face.

In the thickness fall area of the two sections, a section of bar steel is used, the length of the bar steel is less than the width of the solid steel plate 1, and the left side and the right side of the bar steel are respectively left by about 100 mm; be covered with the steel wire on the bar to fix steel wire one end on the bar with welding mode, steel wire length about 200mm ensures simultaneously that the steel wire stretches out solid steel sheet 1 bottom surface more than 100mm, its purpose: the wire brush 32 cleans the small steel grades of the platform to ensure the cleanness of the platform; secondly weld the steel wire on the billet, and the billet passes through the bolt and links on solid steel sheet 1, the whole dismantlement of being convenient for is changed.

The length of the whole slag removing device is about 4 times of the length of fork teeth of the forklift, and after the forklift is inserted into the insertion holes 4 through the fork teeth, the slag removing device is about 100mm and 200mm away from the ground, and the front end of the steel plate is ensured to be tightly attached to the ground under the action of the gravity center of the solid steel plate 1. The hollow square frame 2 is convenient to drive the ground large steel slag to move under the action of the external force of moving the forklift, so that the purpose of preliminary cleaning is achieved; the ground is further processed by means of a wire brush 32 (similar to broom work) for the purpose of 'finishing' the ground.

Those of ordinary skill in the art will realize that the foregoing description is illustrative of one or more embodiments of the present invention and is not intended to limit the invention thereto. Any equivalent changes, modifications and equivalents of the above-described embodiments are within the scope of the invention as defined by the appended claims, and all such equivalents are intended to fall within the true spirit and scope of the invention.
