Moving metal strips can be heat treated with any number or combination of dimensionally variable tempers across widths, lengths, or thicknesses of a metal strip. To provide dimensionally variable heat treatment, an apparatus can include one or more heating units suitable to increase the temperature of a metal strip moving proximate the apparatus to a heat treatment temperature. The apparatus can also include one or more cooling units positioned near the heating units to absorb heat and cool the metal strip to minimize the amount of heat transferred from a first region of the metal strip that is to be treated to a second region of the metal strip that is not to be treated.

An apparatus for feeding and preheating a metal charge toward a melting furnace of a melting plant, comprising at least one conveyor channel for said metal charge, at least one hood disposed above said conveyor channel and scrap detection means able to identify the profile of the metal charge entering said conveyor channel. The present invention also concerns a plant for melting metal comprising said apparatus, and a method to feed and preheat a metal charge.

A nozzle system for a band floating system for floatingly guiding a band-shaped material having a nozzle body having a front edge area and a rear edge area opposite to the front edge area, a front gas nozzle arrangement arranged at the front edge area, a rear gas nozzle arrangement arranged at the rear edge area, and a nozzle arrangement arranged, in the conveying direction, in front of the front gas nozzle arrangement and/or behind the rear gas nozzle arrangement such that a liquid fluid is flowable in a fluid jet into a nozzle floating field in the direction towards a band running plane for temperature-controlling the band-shaped material.

Provided is a hot isostatic pressing (HIP) device that improves the heat uniformity of a hot zone during a pressurization process of an object being processed. This HIP device (100) is provided with: an outer casing (4) having an open outer opening part (4H); an inner casing (5) having an open inn opening part (5H); a heat-insulating body (R) disposed between the outer casing (4) and the inner casing (5); a gas flow generation part (30); and a plurality of first gas conduits (12), A hot zone (P) in which a pressurization process is performed is formed inside the inner casing (5). During the pressurization process, a low-temperature pressurization medium gas which has been generated by the gas flow generation part (30) and has passed through the first gas conduits (12) moves upward in an inner flow passage (L1) between the casings, and then flows into the hot zone (P) from the inner opening part (5H), Even when the pressurization medium gas leaks from the vicinity of a bottom all part (20) and flows into the hot zone (P), the heat uniformity of the hot zone (P) is maintained.
