Converter alloy charging mechanism

Abstract

The invention discloses a converter alloy charging mechanism, comprising a converter, a steel placing operation platform, a steel water tank, a receiving hopper, a blanking hopper, and a rocker rotary unit, wherein, the steel placing operation platform is arranged around the converter, the back side, left side and right side of the converter are respectively provided with a water cooling coaming plate, the water cooling coaming plates are fixed on the steel placing operation platform, the receiving hopper is arranged on the steel placing operation platform at the outer side of the water cooling coaming plate, the blanking hopper is arranged the lower end of the rocker rotary unit. When in a normal blanking position, the receiving port of the blanking hopper is located just below the discharge port of the receiving hopper, and the blanking port of the blanking hopper is located just above the steel water tank, According to the invention, by respectively arranging the water cooling coaming plate at the back side, left side and right side of the convertor, the invention avoids the slag splashing out to damage people; by arranging the receiving hopper and the blanking hopper, the alloy slips into the steel water tank through the blanking hopper, and no splashing of molten steel is generated, thus the situation that operator is in the face of the splashing of molten steel when the operator directly charges the alloy can be avoided, and the personal injury is avoided.

Description

technical field [0001] The invention belongs to the field of molten steel smelting, in particular to a device for blending alloys into molten steel tanks. Background technique [0002] After the molten steel is smelted in the converter of the converter steelmaking plant, the molten steel is poured from the converter into the molten steel tank, and the composition of the molten steel needs to be fine-tuned, and some different types of alloys are added to the molten steel. The time to add the alloy, according to the technical requirements, is to add the alloy during the process of pouring the molten steel, and pour the molten steel while adding the alloy. During the process of pouring the molten steel, red high-temperature steel slag is easy to splash, and a large amount of smoke and heat are generated at the same time. It is easier to add the alloy during this process. Slag splashing occurs, and the elevation difference between the operation platform for putting steel and the...

Problems solved by technology

The time to add the alloy, according to the technical requirements, is to add the alloy during the process of pouring the molten steel, and pour the molten steel while adding the alloy. During the process of pouring the molten steel, red high-temperature steel slag is easy to splash, and a large amount of smoke and heat are generated at the same time. It is easier to add the alloy during this process. Slag splashing occurs, and the elevation difference between the operation platform for putting steel and the mouth of the molten steel tank is 2.6m. In such a working condition, artificial alloying can easily cause smoke and heavy metal dust to be inhaled by the human body, and steel slag splashing can easily cause personal safety accidents, even death event
