The present disclosure provides a converter CO&#x2014;Omixed injection smelting method and a fire point area temperature dynamic control method. The method realizes online monitoring through an infrared temperature sensor installed inside an oxygen lance, dynamically adjusts the mixing ratio of COand Oand the height of the oxygen lance position according to the fire point area temperature changes and process requirements in different smelting stages, so that the secondary smelting system interlockingly and dynamically controls the fire point area temperature and the molten pool heating rate.

A long-life service method for powder-bottom-injecting converter based on collaborative hot replacement of furnace bottom and bottom purging brick belongs to the field of steelmaking technologies using powder-bottom-injecting converters. According to equipment characteristics, process characteristics, and erosion characteristics of the powder-bottom-injecting converter, the design, arrangement, installation, use, maintenance, and replacement of the bottom purging/powder injection bricks are systematically optimized and improved, a technology of automatically detecting the erosion height of bottom purging bricks is adopted, and hot replacement of bottom purging/powder injection bricks and hot replacement of the converter furnace bottom are used collaboratively, which not only can prolong the service life of a single bottom purging/powder injection brick, but also can greatly prolong the overall life of the powder-bottom-injecting converter from 1000-3000 heats in the prior art to 6000-10000 heats. Hence, the life of the powder-bottom-injecting converter is as long as that of a conventional converter.

Embodiments of the present application provide a label switching path calculation method and a label switching path calculation device. In the method, by performing hierarchical level and domain value planning on a node in a network in advance, when an LSP is calculated, hierarchical domain information about each node is acquired, and the LSP is calculated using the acquired hierarchical domain information about each node. Since the hierarchical domain information about each node designates a network position where the node is located, it can be avoided that an LSP obtained by calculation reroutes an access layer according to the hierarchical domain information about each node and a satisfaction criterion for the LSP during the LSP calculation process. In addition, the technical solution provided in the embodiments of the present application needs no manual intervention in the whole LSP calculation process, realizing the automatic calculation of an LSP.

Embodiments of the present invention provide a method for generating a label forwarding table for a non-destination router on a ring topology. Embodiments of the present invention further provide an apparatus for generating a label forwarding table for a non-destination router on a ring topology and a method and system for generating two label switching paths LSPs of different ring directions on a ring topology. Technical solutions provided by the embodiments of the present invention are based on a clockwise label forwarding table and a counterclockwise label forwarding table that are generated for each non-destination router on the ring topology. When it is found that traffic cannot be forwarded to a destination router by using one of the two label forwarding tables, the non-destination router performs traffic switching and uses the other label forwarding table to forward the traffic.
