A multi-window platen oven for simultaneously heating a plurality of blanks, for example aluminum blanks, before forming the heated blanks in a production line is provided. The oven includes a plurality of vertically aligned shelves disposed in an existing press assembly so that no additional floor space is required. The shelves are attachable to an upper press bed and one another. The upper press bed lifts the attached shelves to present an open window for receiving an unheated blank and/or removing a heated blank from the oven. The remaining windows remain closed and continue heating while the blanks are transferred to and from the oven. After closing the one open window, another window opens to receive another unheated blank and/or remove another heated blank. Thus, the multi-window platen oven continuously provides blanks which are ready for warm or hot forming.

A casting component and method for the application of an anticorrosive layer to a substrate, such as the casting component, are provided. The casting component for a device for casting a metal melt includes a metallic basic body and a melt contact surface region which is exposed to the metal melt during casting operation. In the casting component, the metallic basic body is provided in the melt contact surface region with an anticorrosive layer which is resistant to the metal melt and which is formed, using microparticles and/or nanoparticles of one or more substances from a substance group which includes borides, nitrides and carbides of the transition metals and their alloys and also of boron and silicon and Al.sub.2O.sub.3.

Disclosed is a tempering station for the partial heat treatment of a metal component, the station including a processing plane arranged in the tempering station, at least one nozzle, aligned to the processing plane, for discharging of a fluid flow for the cooling of at least a first sub-area of the component, and at least one nozzle box, arranged above the processing plane. The at least one nozzle box forms at least one nozzle area in which the at least one nozzle is at least partially arrangeable and/or which at least partially delimits a propagation of the fluid flow, with the at least one nozzle box being at least partially formed with a ceramic material. The tempering station permits a sufficiently reliable thermal delimitation of heat treatment measures partially acting on the component and/or a sufficiently reliable thermal separation of different heat treatment procedures partially acting on the component.

A molten metal furnace in which molten metal leakage may be avoided or controlled and heat radiation from the furnace body may be controlled. The molten metal furnace has an outer wall on its outer periphery, a molten metal storage part for holding a molten metal therein, and an inner wall forming the molten metal storage part and having a plurality of lining layers, wherein a first lining layer of the plurality of lining layers, having a surface to be in contact with the molten metal, is formed of a refractory material, wherein a sealing material is provided along at least two boundaries present in a range between the first lining layer and the outer wall, and wherein a lining layer sandwiched between layers of the sealing material is formed of a thermal insulation board containing at least silicon dioxide (SiO.sub.2).
