Description
Technical Field
The utility model belongs to the technical field of refining furnace production, and particularly relates to a device for prolonging the service life of a steel ladle slag scraping plate chain.
Background
The technological process adopted by the steel works of Yongfeng harbor Limited company of Shandong iron and steel group is converter-refining furnace-continuous casting, and in order to reduce the heat dissipation of the air in the process of transporting and pouring molten steel, a ladle capping technology is adopted. After the converter finishes the steel placing, adding a ladle cover on a converter ladle cover platform in the molten steel outlet process, after the ladle is hung to a refining furnace seat, taking off the ladle cover from the refining ladle cover platform, and after the refining is finished, hanging to continuous casting from the refining ladle cover platform and the ladle cover to perform molten steel pouring operation.
The ladle cover has the requirement on the slag accumulation along the ladle edge, and refined molten steel is easy to collide with the ladle cover in the outward driving process after excessive slag accumulation, so that the ladle cover falls off and is broken, or a gap exists between the ladle cover and the ladle, and the heat preservation effect is affected.
In order to reduce slag accumulation on the ladle cover, a slag scraping plate is added between the ladle cover platform and the refining station, and slag accumulation on the ladle edge is scraped in the slag feeding and discharging process of molten steel. If the steel slag overflows from the ladle edge to stick steel or higher deposited slag in the smelting process of the refining furnace, when the slag scraping plate is not scraped during outward driving, the slag scraping plate needs to be pulled up by a chain and then molten steel is discharged, so that the damage to the slag hanging plate due to the excessively high stick steel or deposited slag is prevented.
When the ladle edge is too high and the risk of damaging the slag hanging plate is caused when the refined molten steel goes out, an operator pulls the chain to lift the slag scraping plate, the chain rubs with a guard board of a platform guard rail of the refining furnace in the process of pulling up the slag scraping plate, the resistance is increased, meanwhile, the abrasion of the chain is increased, and the service life of the chain is prolonged. In addition, the platform guard rail guard plate may be damaged during the pulling up of the chain.
Therefore, there is a need for a device that extends the service life of a ladle scraper chain.
Disclosure of utility model
The utility model aims to provide a device for prolonging the service life of a steel ladle slag scraping plate chain.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a device for prolonging ladle scraping plate chain life, includes first support frame and second support frame, all be equipped with the through-hole on first support frame and the second support frame, install the connecting rod in the through-hole, the nested sleeve that has on the connecting rod to make the sleeve rotate on the connecting rod.
Specifically, the first support frame and the second support frame are respectively provided with a first support plate and a second support plate which are perpendicular to each other.
Specifically, external threads are arranged at two ends of the connecting rod, so that the connecting rod is fixed on the first support frame and the second support frame through nuts.
The utility model has the following beneficial effects:
1) When the slag scraping plate needs to be pulled up, the chain is positioned on the sleeve, the chain drives the sleeve to rotate, the friction force between the chain and the sleeve is rolling friction force which is far smaller than the sliding friction force between the chain and the guard rail, and the physical consumption of operators is reduced;
2) The chain drives the sleeve to rotate, so that the chain is prevented from directly rubbing the guard board of the platform guard board, and the guard board is prevented from being pulled out by the chain;
3) The friction force between the chain and the sleeve is rolling friction force, so that the abrasion of the chain can be effectively reduced, and the service life of the chain is prolonged;
4) The pulling-up of the chain is more labor-saving, the time for pulling-up the chain in place can be shortened, the influence of pulling-up the slag scraping plate on the production rhythm is reduced, and the stable and normal production order is facilitated.
