Metallurgical furnace oxygen lance slag scraper with rotary scraping and impacting

Abstract

The invention discloses a metallurgical furnace oxygen lance slag scraper with rotary scraping and impacting, structurally comprising: a slag scraping device, a power supply frame, a support and a transmission shaft. The metallurgical furnace oxygen lance slag scraper with rotary scraping and impacting has the advantages that a power supply mechanism and a scraping structure can cooperate with each other such that triangular conical teeth on the surface of a threaded bar provide spiral rotational scraping for slag on the surface of an oxygen lance under the rotational action of the scraping structure so that the slag is cracked; gas leakage due to the oxygen lance breakage caused by surface scratches of the oxygen lance under the action of a traditional slag scraper is avoided; a circularframe rotates synchronously with a scraping barrel, a vibrating plate is ejected out under the action of an ejector rod, the slag that is cracked is impacted, the cracks are extended to break the slagunder the action of external force, the slag on the surface of the oxygen lance is broken to fall under the impact action, and it is avoided that gas leakage is caused by cracking and scratches of the surface of the oxygen lance due to the action of the traditional slag scraper.

Description

technical field [0001] The invention relates to the field of metallurgical industry, more precisely, it is a metallurgical furnace oxygen lance slag scraper which adopts rotary scraping and impact. Background technique [0002] Oxygen converter steelmaking is one of the necessary tools in the metallurgical industry and the steel industry. People have very high requirements for the quality of this type of material when used in daily life. In the refining process, the oxygen lance can directly affect the smelting process. The effect and blowing time will affect the quality and output of the steel. After the refining is completed, because the surface of the oxygen lance is surrounded by some mixed products in the converter, it is necessary for the operator to use a slag scraper to remove the slag on the surface. However, when this kind of slag scraper scrapes the oxygen lance, because of the thickness and hardness of the slag itself, it is easy to scratch the surface of the oxy...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a metallurgical furnace oxygen lance slag scraper that adopts rotary scraping and impact, so as to solve the problem of Because of the thickness and hardness of the slag itself, it is easy to scratch the surface of the oxygen lance when scraping the slag, resulting in scratches or cracks on the wall of the oxygen lance, causing a large amount of gas leakage during use, which affects the metallurgical effect defects
