Problems solved by technology

The conventional argon blowing process system consists of ferroalloy feeding system, wire feeder, temperature measurement and sampling system, top blowing argon equipment and other related equipment. During production, a large amount of smoke and dust are generated during the stirring operation of the top argon gun, which seriously affects the on-site operation of the argon blowing station. , the smoke and dust can easily block other equipment in the argon blowing station, etc., reducing the performance and service life of the equipment

Abstract

The invention discloses an argon blowing process system, which aims to solve the problems of heavy dust and the like in the prior art. The system comprises an iron alloy overhead bunker, a weighing trolley and a movable flue gas collecting cover, wherein the movable flue gas collecting cover is connected with the weighing trolley above the cover through a rope; an argon blowing lance hole, an iron alloy feeding hole and a thread feeder hole are formed on the top of the movable flue gas collecting cover; and an air vent connected with a dust-removing tube is arranged on the side face of the movable flue gas collecting cover. Due to the structure, the cleanliness of production of an argon blowing station is realized, the production environment of the conventional argon blowing station is greatly improved, the system is subjected to traction operation by a conventional weighing trolley of an iron alloy loading system, one-time equipment investment is reduced to a great degree, and the operation rate of corresponding equipment is improved. The cleanliness of technical production is realized, the accurate fine adjustment of molten steel alloying is realized, the uniformity of the temperature and components of the molten steel is improved, and the economic and social benefits are improved.

Description

technical field [0001] The invention relates to the technical field of steelmaking process, in particular to an argon blowing process system for secondary refining of molten steel in a steelmaking workshop. Background technique [0002] The argon blowing station is an effective secondary refining method for the molten steel in the converter, and it has the function of adjusting the temperature and composition uniformity of the molten steel and buffering the production rhythm. The conventional argon blowing process system consists of ferroalloy feeding system, wire feeder, temperature measurement and sampling system, top blowing argon equipment and other related equipment. During production, a large amount of smoke and dust are generated during the stirring operation of the top argon gun, which seriously affects the on-site operation of the argon blowing station. , Smoke and dust can easily block other equipment in the argon blowing station, which reduces the performance and ...
