Description

Technical Field

[0001] This utility model relates to the technical field of electric furnace slag discharge equipment, and in particular to an electric furnace slag discharge flow control device. Background Technology

[0002] Hot-melt slag cotton is a new type of environmentally friendly material, typically formed from high-temperature slag (such as molten metal residue from steel or other metallurgical industrial waste) through specific processing into a fibrous material. It mainly involves cooling, solidifying, and drawing the molten metal waste to obtain cotton-like fibers, which are used as insulation, heat preservation, and fireproofing materials. Processing is generally carried out in an electric furnace. Electric furnace slag removal usually refers to the stratification of molten metal and slag within the furnace during electric furnace smelting, where the slag is a byproduct of the smelting process. Sometimes, slag removal is done to remove impurities from the metal to improve its quality, or to facilitate slag removal and avoid affecting the operating efficiency of the electric furnace.

[0003] In practice, the following problems still exist when slag is discharged using existing technologies: if the residue from the hot melt slag cotton-making process is not cleaned up in time, it will cause accumulation inside the electric furnace. On the one hand, this increases the labor intensity of subsequent cleaning, and on the other hand, it can easily cause equipment blockage, making it difficult to control the slag discharge flow rate and affecting the requirements during use.

[0004] Therefore, this utility model provides a device for controlling the slag discharge flow rate of an electric furnace. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide an electric furnace slag discharge flow control device.

The heating chamber and the drive motor are both electrically connected to the control panel.
