  • Publication number: 20210214813
    Abstract: Disclosed is a slag discharging method in a process of producing ultra-low phosphorus steel, which relates to the technical field of iron and steel smelting, and in which molten steel is mixed with lime first to produce basic slag; then converting is performed with oxygen to increase the oxidizability of the basic slag; and a carbon-containing reducing agent is finally added, so that in the process that the carbon is oxidized to release a large amount of carbon monoxide gas, phosphates are captured, and the basic slag is rapidly foamed and overflows from the opening of the steel ladle, so that conditions are no longer available for rephosphorization. The slag discharging method is simple and convenient to operate, does not have high requirements on the equipment, has relatively good dephosphorization effect, and can be used to prepare an ultra-low phosphorus steel containing less than 0.003% phosphorus.

  • Patent number: 10523542
    Abstract: A first integrated cloud is identified in a self-driven testing platform. The interoperability of the first integrated cloud with a plurality of other integrated clouds is tested. A service chain to verify a service chain path connectivity between the first integrated cloud and the plurality of other integrated clouds is created. Performance of the service chain is determined as is whether the service chain performance meets a benchmark requirement. If the service chain performance does not meet the benchmark requirement, service chain inventory data and adjacent neighbor connection information is retrieved. Real time network configuration data from the first integrated cloud and the plurality of other integrated clouds is retrieved and any mismatched network configuration data is compared and corrected.
