This application provides a slag removal device, comprising: a fixed plate; a first fixed frame disposed on the fixed plate, the first fixed frame having first sliding channels spaced apart along its length, and a first movable frame disposed within the first fixed frame; and a second fixed frame slidably disposed on the fixed plate, the second fixed frame having second sliding channels spaced apart along its length. This invention enables alternating feeding, ultimately completing the cleaning of protective slag within the cyclone pool. The automated slag removal method eliminates the need for manual operation of the overhead crane and direct personnel involvement in the slag removal operation, significantly improving slag removal efficiency, shortening the slag removal cycle, and avoiding the problem of long-term occupation of overhead crane resources. Furthermore, the operation process does not require personnel to approach the cyclone pool, effectively avoiding safety hazards caused by operational errors and unknown pool conditions, and reducing the labor intensity and safety risks for operators.

This invention relates to the field of comprehensive utilization technology of iron and steel smelting resources, specifically to a method for the direct recycling and utilization of iron-rich red mud in converter steelmaking. The method includes the following steps: Step 1: Retaining slag, including MgO, in the converter for slag splashing and furnace protection; Step 2: Adding fine-grained limestone to the converter; Step 3: Adding iron-rich red mud to the converter, and shaking the converter 2-3 times after the mud has been added; Step 4: Verticalizing the converter and blowing nitrogen into it at least once using a top-blowing method, with each blowing lasting 3-5 seconds and an interval of 10 seconds between each blowing; Step 5: Adding scrap steel to the converter, waiting 0-5 minutes, then adding molten iron and starting the blowing process. This invention directly applies iron-rich red mud to the converter steelmaking process, achieving dephosphorization of molten iron with high phosphorus content without the use of flux.

This invention discloses a slag removal device for a sugarcane combine harvester. The slag removal device includes a screening chamber, a screening chamber drive, a slag discharge chamber, and a blower. The screening chamber is rotatably mounted on the cutting and conveying mechanism and is provided with a screening channel. A discharge channel communicating with the discharge port of the cutting and conveying mechanism and the screening channel is provided on its side. The screening chamber drive is mounted on the cutting and conveying mechanism and can drive the screening chamber to rotate relative to the cutting and conveying mechanism. The slag discharge chamber is installed above the screening chamber and is provided with a slag discharge channel communicating with the screening channel. The blower is rotatably suspended on the top of the slag discharge chamber and located at the connection between the screening chamber and the slag discharge chamber. This invention's combined slag removal method of rotating the screening chamber and swirling the blower solves the problems of low slag removal efficiency, easy clogging, and poor separation of light slag in existing slag removal devices. It achieves efficient separation of slag and sugarcane, high slag removal efficiency, low impurity residue rate, and effectively reduces sugarcane loss rate while avoiding equipment blockage.
