Abstract
The invention relates to a revolving furnace slag pressing agent and a revolving furnace slag pressing method, which belongs to the field of metallurgy. The invention solves the technical problem of providing the revolving furnace slag pressing agent, which can shorten the slag spattering time, and a revolving furnace can realize the steelmaking without furnace turning. The revolving furnace slag pressing agent of the invention consists of the following ingredients by weight parts: 8 to 15 parts of SiO2, 1 to 6 parts of Al2O3, 20 to 30 parts of Fe2O3, 10 to 20 parts of MgO and 30 to 50 parts of CaO. The invention reduces the overflowing quantity of the furnace slag during the revolving furnace steelmaking, improves the slag spattering furnace protection effect, and shortens the slag spattering time by about 2 minutes. The invention provides a novel path for the furnace slag regulation during the spattering smelting, and has wide application prospects.
Description
technical field [0001] The invention relates to a converter slag pressing agent and a converter slag pressing method, belonging to the field of metallurgy. Background technique [0002] Converter slag splashing has always been a major technical problem in converter smelting. With the continuous updating of converter smelting equipment, especially in converter smelting equipped with automatic steelmaking system, the slag splashing is more prominent. Due to the strong oxidation of the final slag of the converter, the slag foams severely during tapping, and the problem of slag gushing at the furnace mouth is prominent, and the conditions for direct tapping of the furnace are not available. Therefore, automatic steelmaking requires the operation of the converter without tapping the furnace. In order to achieve the purpose of not tapping the furnace, it is necessary to adjust the slag before tapping. Contents of the invention [0003] The first technical problem to be solved b...
