Technical Field

[0001] This utility model relates to the technical field of high-temperature melting of waste stainless steel, specifically a high-temperature melting device for waste stainless steel. Background Technology

[0002] A high-temperature melting device for scrap stainless steel is a specialized piece of equipment for processing and recycling scrap stainless steel materials. This device uses high-temperature melting technology to remelt the scrap stainless steel materials for further processing and reuse. The device generates high temperatures through electric heating or fuel combustion, heating the scrap stainless steel materials to their melting point and turning them into a liquid. During the melting process, impurities such as oxides and carbides can be removed by adding chemical reagents or physical methods. The molten stainless steel liquid can be cast into new metal ingots or used directly to manufacture new stainless steel products.

[0003] Common high-temperature melting devices for scrap stainless steel generate large amounts of smoke, harmful gases, and volatile organic compounds during the melting process. These pollutants are directly emitted into the atmosphere, causing serious air pollution, affecting the surrounding environment and residents' health, and bringing certain adverse effects to people's use.
