Description

Slag scraper for lower nozzle of steel ladle

Technical Field

The application relates to the technical field of steel ingot production, in particular to a slag scraper for a lower nozzle of a steel ladle.

Background

The ladle is an important device in steel plants and is a bearing container for the whole process from a steel furnace to a casting machine. In the continuous casting process, after molten steel is subjected to a series of refining in a ladle, the ladle is lifted to a ladle turret, and the molten steel is firstly injected into a tundish from a water gap of the ladle and then is injected into a crystallizer through a water gap of the tundish.

In the casting process, the casting operation needs to be protected by adopting the pouring of the steel ladle. The method is generally adopted to use a protective casting pipe on a steel ladle water outlet and protect an argon seal and an asbestos gasket. Because the asbestos washer is sleeved at the outer end of the lower nozzle of the steel barrel and is upwards extruded by the protective casting pipe to be tightly contacted with the outer end of the lower nozzle of the steel barrel, and simultaneously, due to the high temperature of the molten steel, the asbestos is firmly sintered on the steel shell of the lower nozzle of the steel barrel.

When the steel containing barrel is subjected to thermal repair treatment, asbestos residues on the outer wall of the lower water opening need to be removed, otherwise, the normal installation of a protective casting pipe and an asbestos gasket is influenced when the steel containing barrel is reused, so that the protective casting effect is deteriorated, molten steel is possibly sucked and nitrogen is increased when the protective casting effect is serious, and aluminum and titanium in the steel are oxidized and the content of impurities in the molten steel is increased. The traditional method for removing asbestos adhered to the outer wall of the lower nozzle is to scrape asbestos residues by using a steel chisel, and has the defects of heavy steel chisel, small scraping surface and low speed. The hot repair time of the steel containing barrel is prolonged, the temperature drop of the steel containing barrel is increased, the turnover difficulty of the steel containing barrel is increased, and the quality defect of a casting blank is caused by abnormal casting protection when scraping is not clean.
