Description
Technical Field
The utility model belongs to the technical field of metallurgical industry converter oxygen rifle equipment, especially, relate to an efficient converter oxygen rifle slag scraper
Background
The oxygen lance is one of key parts of an oxygen blowing device of a top-bottom rich-blowing converter, and is used for blowing oxygen to a molten pool in the converter during blowing and blowing nitrogen into the converter after blowing is finished so as to perform slag splashing and furnace protection to protect a furnace lining. During blowing, an oxygen lance connected with an oxygen supply pipe of an oxygen valve station in a workshop enters a converter shell through a lifting device, and when the oxygen lance is at a certain height from the liquid level of molten iron, high-speed oxygen is blown to high-temperature liquid metal, so that the metal is smelted.
Steel slag inevitably adheres to the oxygen lance in the blowing and slag splashing furnace protecting processes of the oxygen lance, if the steel slag cannot be cleared in time, the slag layer on the oxygen lance adhered with the slag is increased by 3-5mm as the number of smelters is increased, and the slag layer is like a snow ball, because of the complexity of the operation of the oxygen lance, the slag adhesion is inevitably steel slag mixed adhesion, sometimes even a layer of steel slag, so that the slag adhesion of the oxygen lance is thicker and thicker, and the oxygen lance can not normally lift and run, namely, the oxygen lance mouth part can not be lifted, at the moment, the oxygen lance which is adhered with slag can only be cut off by a flame cutting knife, the cut oxygen lance is disassembled, the oxygen lance is replaced, thereby greatly reducing the service life of the oxygen lance, increasing the loss cost of the oxygen lance, needing frequent cutting and replacement of the lance, destroying the continuity of the steel-making production of the converter in serious cases and increasing the labor intensity of workers.
The converter is provided with a set of slag scraper which is arranged above an oxygen lance insertion opening of a converter platform. The slag scraping principle of the existing oxygen lance slag scraping equipment is consistent, when the converter blowing and slag splashing protection are finished, the oxygen lance is lifted out of an oxygen lance opening, a pneumatic control system of an oxygen lance slag scraper drives a left mechanical arm and a right mechanical arm, so that a U-shaped or round slag scraper tool bit of the mechanical arms is folded to enclose the oxygen lance adhered with steel slag, and when the oxygen lance is lifted, an alloy tool edge on the slag scraper tool bit scrapes the steel slag adhered on the oxygen lance.
The device has the defects that in the slag scraping process, because the slag sticking amount of the oxygen lance is larger, the slag scraping cutter can be wedged into steel slag like a wedge, the oxygen lance cannot move up and down, and the slag scraping cutter head cannot move back, so that the gun clamping accident is caused, the slag scraping time is long, and the working efficiency is low.
