Method for slag chemistry control in a refractory lined vessel during the process of refining metal by the injection of oxygen gas during a period of oxidation and by the injection of nonoxidizing gas or gases during a period of reduction and melt specification adjustment such that the slag at the completion of the refining process will have a preselected composition consisting essentially of A% alumina (Al. sub. 2 O. sub. 3), B% silica (SiO. sub. 2), C% CaO and D% MgO and a ratio X of alumina to silica equal to a preselected value of between about 0. 1 to 10. The preselected slag chemistry at the completion of refining is achieved by using a combination of aluminum and silicon to achieve as completely as possible the preselected ratio of alumina to silica in the slag while at the same time satisfying the fuel, reduction, and specification silicon requirements of the bath at the given intervals corresponding to the end of the oxidizing period, the reducing period and the final trim.

Calcium carbide is efficiently and safely employed to provide heat to a steel melt during subsurface refining by providing the steel melt with acidic component(s) and/or oxidizable component(s), which when oxidized will yield acidic components, in a amount sufficient to flux the products of calcium carbide oxidation, while insuring that the calcium carbide does not reside in the bath for more 5 minutes prior to the initiation of its oxidation.

Disclosed are systems and methods for performing efficient job applicant screening. In particular, a network-based system is established for gathering applicant information from an applicant remotely. Analysis of the received information is performed and evaluated pursuant to a first level of screening that can be done without excessive use of resources. Upon passing the first level screening, background checks and/or interviews, which require substantial resources, are further conducted. Applicants who pass the first level of screening are scheduled for interviews, including the optional initiation of personal interviews via video chat.

A system and method for managing on-demand services includes integrating a consumer's personal resources with institutional service providers. The consumer's service request is fulfilled by streamlining the selection of resources and seamlessly extending the search to a larger system when the consumer's personal resources are exhausted. The system and method advantageously provides focused communications to selected contacts and automates the selection process.
