Detachable multi-hopper type alloy gas baking device

Abstract

The invention discloses a detachable multi-hopper type alloy gas baking device. The detachable multi-hopper type alloy gas baking device comprises scrap steel hoppers, oxygen blowing pipes, quick couplings A, quick couplings B, metal hoses A, metal hoses b, gas dedicated ball valves A, gas dedicated ball valves B, a gas steam pocket, an air compressing wind steaming pocket, a gas dedicated ball valve C and a gas dedicated ball valve D. According to the device, about 20 tons of alloy can be baked at one time, and small-tonnage multi-kind alloy baking can be achieved. The occupied space is small, the device can be suitable for multiple stations of a revolving furnace, an argon oxygen furnace, a high-steel refining furnace and the like, and it is ensured that the alloy baking temperature is larger than or equal to 200 DEG C. The aim that the alloy is added in the furnaces rapidly, safely and economically is achieved, in-furnace alloy baking meets the technological requirements, and therefore gas in in-furnace steel is controlled, molten steel waiting time is reduced, the tonnage steel smelting cost is reduced, and the personal injury or equipment damage accident is reduced.

Description

technical field [0001] The invention relates to technical equipment for electric furnace steelmaking, in particular to a detachable multi-hopper type alloy gas baking device. Background technique [0002] After more than 40 years of development in my country's steel production, especially in the past 20 years, the phenomenon of overcapacity has appeared at this stage. In order to adapt to the market and occupy a higher share in the market competition, improving the quality of steel is the top priority. [0003] Due to the limitation of the special steel workshop, the high-level silo of the high-steel refining furnace and the high-level silo of the converter cannot be baked, and can only be baked in the low-level silo. Because the low-level baking equipment is simple and irregular, the baking is uneven and the gas energy consumption is large. During the smelting process, a large amount of alloys are added to the molten steel, causing the temperature of the molten steel ...

AI Technical Summary

Problems solved by technology

[0003] Due to the limitation of the special steel workshop, the high-level silo of the high-steel refining furnace and the high-level silo of the converter cannot be baked, and can only be baked in the low-level silo.

Because the low-level baking equipment is simple and non-standard, the baking is uneven and the gas energy consumption is large

During the smelting process, a large amount of alloys are added to the molten steel, causing the temperature of the molten steel to drop sharply. At the same time, the content of hydrogen, oxygen, nitrogen and other gases in the steel increases, which prolongs the refining time of the high-steel refining furnace, further causing oxygen consumption, power consumption, etc. waste of energy
