A large slag tank repair technology

Abstract

The invention discloses a large slag ladle repairing technology. The large slag ladle repairing technology is characterized in that a hanger shaft of a slag ladle is milled through a machining device in a manner that a cutter rotates while the workpiece stays still, so that the diameter of the hanger shaft is reduced; the hanger shaft with the reduced diameter is then sleeved by a shaft sleeve, and the outer diameter of the shaft sleeve is identical to the diameter of the hanger shaft before the diameter reduction. The large slag ladle repairing technology disclosed by the invention has the advantages that the diameter of the worn-out hanger shaft of the slag ladle is reduced to 270 mm through machining, and the hanger shaft is then sleeved by the shaft sleeve with a diameter of 300 mm, so that the slag ladle can be reused after repair, which greatly prolongs the service life of the slag ladle and saves the production cost.

Description

technical field [0001] The invention relates to the steelmaking industry, in particular to a large-scale slag tank repair technology. Background technique [0002] Iron and steel enterprises will produce a large amount of steel slag in their daily production. The steel slag is poured into the slag tank and transported to the slag treatment field or workshop, and then the subsequent slag treatment is carried out. The slag tank containing steel slag is an indispensable and important container for steelworks to maintain normal production. [0003] The large slag tank used for steelmaking has a weight of 24 tons, the height of the slag tank is 2900mm, and the center of the two suspension shafts is 3620mm. This workpiece is a container for high-temperature industrial waste in the steelmaking plant. The hook is directly hooked on the hanging shaft of the slag tank to dump industrial waste, and the hook is directly in contact with the hanging shaft. During the continuous dumping o...
