摘要:
A high-quality hot rolled steel sheet is manufactured with a high production efficiency and a low cost, from a long, hot slab, using a combination of continuous casting facilities and a plate reduction press machine.
摘要:
A method and hot rolling apparatus for producing a hot rolled steel sheet include a roughing rolling mill to roughing roll a heated slab into a sheet bar, at least one solenoid-type induction heater arranged for re-heating the sheet bar over its entire width, and a finish rolling mill arranged to finish roll the re-heated sheet bar into a hot rolled steel sheet having a predetermined thickness. An initial temperature before rolling is set to be low, and re-heating of the sheet bar is carried out around the middle of the hot rolling apparatus. The thermal energy required for rolling is thereby reduced as a whole without damaging the quality of the resulting hot rolled steel sheet. A descaling apparatus is provided prior to the finish rolling mill to remove oxide scales on surfaces of the sheet bar, whereby the resulting hot rolled steel sheet is free of scale flaws and exhibits superior surface properties.

At the start of power supply from a power supply device to an induction line, the oscillation frequency of an inverter of the power supply device is set at a predetermined frequency shifted from the resonance frequency of a resonant circuit. After a predetermined time, the frequency is changed from the predetermined frequency to the resonance frequency. Thus, at the start of power supply, only small power is obtained by the resonant circuits in all transport carriages from the induction line in a full-load condition. Thus, total power is suppressed within power that can be supplied by the power supply device, avoiding an overloaded condition of the power supply device.

An electrical plug-provided cord has a cord including lead wires and an outer cover for covering the lead wires, an electrical plug including plug blades connected to the lead wires at a tip of the cord and a plug outer housing for covering a part of the cord and a part of the plug blades from base parts of the plug blades to the outer cover at a tip part of the cord, and a coupling member which surrounds the tip part of the cord in close contact and is coupled to the plug outer housing by thermal welding. The plug outer housing is formed of a synthetic resin. At least an interface of the coupling member with the plug outer housing is formed of a heat-weldable material which is thermally weldable with the plug outer housing.

When an IP (Information Provider) server is accessed from a mobile station, a gateway server determines whether or not the IP server is to be IP billed. If it is not to be IP billed, then user billing is applied. In this case, the gateway server sends a user management number of the mobile station and the number of exchanged packets to a billing system. The billing system calculates a communication fee in accordance with the number of packets, and issues a bill to the user specified by the user management number. On the other hand, if the accessed IP server is to be IP billed, then IP billing is applied. In this case, the gateway server sends the number of exchanged packets and the address of the accessed IP server to the billing system. The billing system calculates a communication fee in accordance with the number of packets, and issues a bill to the IP.
