Abstract:
The present invention relates to a furnace, in particular a continuous furnace, for controlling a temperature of at least one substrate (102). A housing (100) of the furnace comprises an intake opening (103) and an outtake opening (104), wherein between the intake opening (103) and the outtake opening (104) a temperature-controlled section (105) is formed. A carrier element (120) for carrying the at least one substrate (102) is movable along a transport direction (101) through the intake opening (103) into the temperature-controlled section (105) and from the temperature-controlled section (105) through the outtake opening (104). A temperature controlling element (106) is thermally coupled to the temperature-controlled section (105) for controlling the temperature of the temperature-controlled section (105). The temperature-controlled section (105) comprises a gas inlet (108) through which a gas (110) is blowable for controlling the temperature of the temperature-controlled section (105).
Abstract:
A roll-to-roll or reel-to-reel RTP tool Including a reactor having a continuous insert placed in a primary gap of the reactor is provided. The primary gap of the reactor is de.fmed by peripheral reactor walls including a top reactor wall, a bottom reactor wall and side reactor walls. The continuous insert includes a continuous process gap through which a continuous workpiece travels between an entry opening and an exit opening of the insert. An inner space exists bemreen at least one of the insert walls and at least a portion of the peripheral reactor walls that make up the primary gap. At least one gas inlet is connected to the inner space, and at least one exhaust opening connects the process gap as well as the inner space to outside the reactor and carries any gaseous products to outside the process gap and the primary gap of the reactor.
Abstract:
The present invention relates to a continuous press hardening process, and an apparatus therefor. The present invention comprises: a slab casting step for continuously casting molten steel refined in an electric furnace and blast furnace to make slabs, followed by re-heating and hot-rolling the slabs to prepare a hot-rolled steel sheet; a blanking step after the slab casting step for transferring the hot-rolled steel sheet to a blank through a sealed oven and then blanking the hot-rolled steel sheet; and a press hardening step after the blanking step for transferring the hot-rolled steel sheet to a press mold and then press-molding it. Since the present invention can immediately inject the high-temperature steel sheet generated in hot-rolling in the press hardening step, an additional re-heating step is not required. Thus, the present invention has an effect of reducing costs through simplification of a process.
Abstract:
A reheat and tunnel furnace system, and heating processes therefor, are provided. A hydrocarbon fuel and steam mix is supplied to a chemical recuperator that uses heat from the waste gas of the reheat or tunnel furnace to produce preheated reformed fuel to the burners of the reheat or tunnel furnace. The steam may be supplied from a waste heat boiler.
Abstract:
A waste heat recovery and utilization apparatus for a rapid cooling zone of a ceramic production line furnace comprises a heat exhaust duct (3) arranged on an upper portion of the furnace in the rapid cooling zone and communicated with the chamber of the furnace, and a cushion barrier zone (7, 8) arranged between the upper portion of the furnace and the communicated heat exhaust duct, and including an upper barrier (7) and a lower barrier (8), both with heat gas throughholes (9) thereon. A waste heat recovery and utilization method comprises: arranging a cushion barrier zone on the top portion of the furnace chamber in the rapid cooling zone, extracting and transporting the heat within the cushion zone to an interior chamber of a spray drying tower in the ceramic production line, so that no additional heat resource is necessary for the drying tower.
