| 摘要 |
The invention relates to a quenching plate made of a matrix composite material, comprising a ferromagnetic phase in which a high temperature stable phase is embedded. Example of an embodiment: In order to produce the matrix composite material, 96 wt. % iron and 4 wt. % MgO are mixed. The powder mixture is pressed into green plates. The green plate are sintered and rolled into the desired thickness of 0.8 mm to 1.2 mm The rolling can be done in several rolling steps, between which the sinter plates are aged. After the last rolling step, the sinter plates are preferably aged once more. The plates produced of the matrix composite material in said way are then coated galvanically with a 5 to 10 micrometer thin electrically conductive layer, for example a copper layer.
