Problems solved by technology

However, when applied in the field of steelmaking technology, the glass of the high-temperature camera (especially the outer glass) will still be defaced. On average, it takes about a week to clean the outer glass of the lens or replace the outer glass in about a month. Imaging reliability and maintainability are adversely affected

Abstract

The invention discloses an air curtain system for improving the imaging quality of an intelligent slagging-off camera. An airflow accelerating device is additionally arranged on the outer layer of anexisting camera, so that a layer of central air curtain area is formed, it is guaranteed that a formed air curtain can block most of dust, splashed molten iron and slag, and large impact fluctuation is not generated on the liquid level in a molten iron tank; besides, a plurality of industrial fans are arranged around the camera in an array mode, then a layer of peripheral air curtain area is formed, a complete air curtain wall is formed under the combined action of the peripheral air curtain area and the central air curtain area, the service life of the camera is prolonged while the camera isprotected, and the imaging quality of the camera is improved.

Description

technical field [0001] The invention relates to a molten iron pretreatment process in steelmaking technology, and more specifically relates to an air curtain system for improving the imaging quality of an intelligent slag removal camera. Background technique [0002] In the pretreatment process of molten iron in the metallurgical industry, the molten iron needs to be desulfurized, dephosphorized and desiliconized by powder spraying or KR (mechanical agitation desulfurization), especially before and after KR stirring. To meet the production needs of (ultra) clean steel. [0003] At present, the molten iron slag removal process at home and abroad is manual slag removal by operators (by the machine or remotely). The working environment of slag removal next to the machine is harsh, which seriously affects the physical and mental health of operators; while remote slag removal is greatly affected by human factors, which will cause fluctuations in production quality. Case. [00...
