Abstract

The utility model provides an automatic sediment device that adds of square billet continuous casting crystallizer covering slag, its characterized in that, the bottom export of hopper and unloading union coupling, the unloading pipe links to each other with the leather hose through the governing valve again, installs forked feeding mouth in the export of leather hose, and the leather hose is fixed through the couple on the middle package shell, and forked feeding mouth card is in the both sides of immersion nozzle, not contact with the immersion nozzle. The utility model discloses an automatic sediment device that adds of square billet continuous casting crystallizer covering slag can reduce workman's intensity of labour, avoids the manual work to add the uncontrollable factor of sediment, improves the covering slag and adds the quality, has reduced all kinds because of adding the technological accident that the sediment quality arouses not in place, improves the continuous casting billet and even the whole quality of steel product.

Description

Automatic slag adding device for casting powder of square billet continuous casting crystallizer
Technical Field
The utility model belongs to the technical field of metallurgical steelmaking, concretely relates to automatic sediment device that adds of square billet continuous casting crystallizer covering slag.
Background
And injecting qualified molten steel into the tundish, shunting the molten steel through the tundish and entering the crystallizer through the sliding water gap and the submerged water gap. The crystallizer is a bottom-free ingot mould which is forced to be cooled by water, and molten steel is solidified into a blank shell with required specification and shape in the crystallizer. By the oscillation of the mold, the shell gradually detaches from the mold wall and forms a primary cast strand. In order to prevent the blank shell of the casting blank from being bonded with the inner wall of the crystallizer, reduce the withdrawal resistance and the abrasion of the inner wall of the crystallizer and improve the surface quality of the casting blank, the crystallizer needs to be lubricated by special covering slag. The addition of the covering slag has special requirements, and the covering slag must be added slowly from the left side and the right side of the submerged nozzle in a less, more frequent and more uniform manner. The liquid level of the steel is ensured not to be exposed, the slag surface is red and bright on the four walls of the crystallizer, and the slag is natural color of the casting powder at other places. The thickness of the slag layer (10 mm of liquid slag and powder slag) is within the range of 35-40mm, and the like.
At present, many steel mills still adopt a mode of manually adding the covering slag for continuous casting pouring, and because the covering slag is added to meet the strict requirement, huge pressure is brought to the steel pouring work of a pouring worker in continuous casting, and the covering slag is frequently added to each crystallizer, so that the labor intensity of the worker is greatly increased. Moreover, the mode of adding the covering slag manually is influenced by factors such as the responsibility of workers, the quality of the added slag is difficult to ensure, and finally, the quality of the continuous casting billet and even the steel product is directly influenced.
Disclosure of Invention
The utility model aims at providing a billet continuous casting crystallizer covering slag automatic slag adding device with simple structure, convenient use and reliable performance.
The utility model discloses an automatic sediment device that adds of square billet continuous casting crystallizer covering slag, including hopper, unloading pipe, governing valve, its characterized in that, the bottom export and the unloading union coupling of hopper, unloading pipe link to each other with the leather hose through the governing valve again, installs Y-shaped feeding mouth in the export of leather hose, and the leather hose is fixed through the couple on the middle package shell, and Y-shaped feeding mouth card is in the both sides at the immersion nozzle, not with the contact of immersion nozzle.
The utility model discloses an automatic sediment device that adds of square billet continuous casting crystallizer covering slag theory of operation is, and the covering slag relies on self gravity to flow out from the hopper, controls the flow size through the governing valve, adds in the crystallizer of immersion nozzle left and right sides through Y-shaped feeding mouth at last. The arrangement of the leather pipe section is to facilitate the collection and release of the feeding pipe when the tundish is replaced, and the forked feeding nozzle can enable the covering slag to be added more uniformly. During the use, fill the covering slag in the hopper before the continuous casting is started to after the immersion nozzle has been established, put down this automatic slag feeding device's forked feed mouth, adjust suitable feed position, open the governing valve and add the covering slag to the crystallizer, according to the reasonable valve aperture of covering slag flow control, in-process is in good time the hopper installs the covering slag additional and finely tunes the valve aperture, has realized the automatic of continuous casting crystallizer covering slag and has joined.
The utility model discloses an automatic sediment device that adds of square billet continuous casting crystallizer covering slag has following beneficial effect: the labor intensity of workers is reduced, the uncontrollable factor of manual slag adding is avoided, the adding quality of the covering slag is improved, various process accidents caused by the incomplete slag adding quality are reduced, and the overall quality of continuous casting billets and even steel products is improved.
