    摘要: In order to support a system of changing a design of a parts constituting a product, both a parts composition information database for storing and supervising parts compositions of various products, and a related section information database for storing various sections and/or persons in charge of assessing design change capability in connection with the product are provided. Information of design change objective is input so as to retrieve and specify one or more products employing the design change parts from the parts composition information database in accordance with the input parts information. In accordance with the specified product, the related section information database is retrieved so as to select sections and/or persons. A request for assessing the parts design change capability is electronically transmitted to the selected one or more sections and/or persons. Plural assessment resultants are received from the assessment requesting destinations so as to determine if a formal design change instruction can be released.

    摘要: In a vacuum degassing and decarburization treatment, the present invention uses a CO.sub.2 gas as a recirculating gas and as a stirring gas without inviting stoppage of decarburization and an increase in the carbon concentration and moreover, without an increase in the amount of addition of an alloy, and can reduce the gas cost. The present invention provides a production method for a low carbon molten steel which comprises blowing a CO.sub.2 gas from the start of degassing treatment till the carbon concentration of the molten steel reaches 50 ppm in vacuum degassing and decarburization treatment of the molten steel, and thereafter blowing an Ar gas.
