摘要:
An arc evaporation coating source includes a target made of a coating material to be vapor-deposited, a ferromagnetic yoke for influencing the vapor deposition of the coating material to be vapor-deposited and at least one permanent-magnetic body for influencing the vapor deposition of the coating material to be vapor-deposited. The ferromagnetic yoke is disposed in contact with the target. The permanent-magnetic body is fastened to the target by the ferromagnetic yoke.

A method of starting a smelting process in a smelting vessel includes heating frozen slag and forming molten slag and draining molten slag from a forehearth connection via a forehearth and establishing a clear flow path through the forehearth connection and thereafter hot starting the smelting process.
摘要:
A method for the continuous production of steel using metal charge material that is preheated in an upper part of a melting vessel, is then melted in a lower part of the melting vessel with fossil fuels and the molten material is continuously discharged into a treatment vessel in which the desired steel quality is adjusted while gases are introduced into the melting vessel from the exterior to afterburn the melting exhaust gases. The process gases are step-wise afterburned when ascending in the melting vessel by introducing the afterburn gases into the interior of the charge material column by way of an interior shaft that projects into the material column and in whose walls inlet openings for the gases are disposed and form afterburn planes arranged one on top of the other.
