High-efficiency steelmaking converter system

Abstract

The invention discloses a high-efficiency steelmaking converter system. The high-efficiency steelmaking converter system comprises a converter, an oxygen lance system, an oxygen supply system, a tilting mechanism, a steel ladle, a control system, a thermal infrared imager, an image processing system and a display; the oxygen lance system is located above the converter, and is composed of a suspension rod, a hydraulic control system and an oxygen lance assembly; the hydraulic control system is mounted on the suspension rod; the oxygen lance assembly is mounted on the suspension rod by use of a lifting device; a backing ring is mounted on the converter; one side of the backing ring is connected with the tilting mechanism; an angle encoder is mounted on the other side of the backing ring; the angle encoder is connected with the tilting mechanism and the control system; the steel ladle is located between the converter and the thermal infrared imager; the thermal infrared imager is connected with the image processing system; the control system is connected with the image processing system; the display is further connected to the image processing system. The high-efficiency steelmaking converter system is capable of effectively improving the quality of molten steel and reducing the steelmaking cost.

Description

【Technical field】 [0001] The invention relates to the technical field of industrial smelting furnaces, in particular to the technical field of high-efficiency steelmaking converter systems. 【Background technique】 [0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloy as the main raw materials. The steelmaking process is completed in the converter by the physical heat of the molten iron itself and the heat generated by the chemical reaction between the components of the molten iron without the aid of external energy. According to the refractory material, the converter is divided into acidic and alkaline; according to the position where the gas is blown into the furnace, there are top blowing, bottom blowing and side blowing; according to the type of gas, it is divided into air converter and oxygen converter. Basic oxygen top-blown and top-bottom compound-blown converters are currently the most commonly used steelmaking equipment due to their fast product...

Problems solved by technology

When tapping the steel, it is necessary to strictly control the content of steel slag in the molten steel to ensure the quality of the steel. The traditional converter lacks an effective slag detection system when tapping the steel. Increase, higher steelmaking cost
