Abstract

The invention discloses a novel iron alloy baking system and process based on a steel refining furnace, which are designed because the conventional iron alloy baking process is high in cost. The novel iron alloy baking system and process based on the steel refining furnace comprises a movable concentrating bucket, a concentrating bucket roaster and a concentrating bucket insulation cover device, wherein iron alloys needed by the steel refining furnace are transported to a baking position from a material receiving position in the movable concentrated bucket; the iron alloys are baked to a target temperature by the concentrated bucket roaster; the iron alloys in an aggregate bin are thermally insulated by the concentrating bucket insulation cover device; the iron alloys are transported to a discharging position by the movable concentrated bucket so as to be discharged. The novel iron alloy baking system and process based on the steel refining furnace realize stable supply of high-temperature iron alloys needed by the steel refining furnace for each steelmaking process.

Description

technical field

[0001] The invention belongs to the technical field of steelmaking technology, and in particular relates to a novel ferroalloy baking system and technology based on a steelmaking furnace. Background technique

[0002] Iron and steel is the basic industry of the national economy. With the rapid development of the national economy, my country's crude steel production has been increasing in recent years. In 2013, my country's crude steel production has reached 779 million tons per year, accounting for 48.48% of the global crude steel production.

[0003] Reducing the tapping temperature of steelmaking is one of the important ways to reduce the consumption of steelmaking raw materials, increase the service life of steelmaking furnaces, and reduce the cost of steelmaking production. Large and medium-sized iron and steel enterprises at home and abroad have conducted a lot of practical research on reducing the tapping temperature and reducing the temperature drop in...
