Embodiment Construction

[0023] The present invention will be described below by way of embodiments with reference to the accompanying drawings.

[0024] figure 1 An example of a possible configuration is shown in plan view, in which the radar measuring probe 3 is arranged in a concealed manner in a water-cooled shielding housing 1 , which is flange-mounted on the likewise water-cooled mold cover of the ESR device 10 . 2 on.

[0025] figure 2 The partially cut-away schematic section shows, in a plan view, the shield housing 1 which is flange-mounted on the mold cover 2 , in which the radar measuring probe 3 is arranged, and the curved measuring tube 4 passes through the interior of the mold. Above, there is a cleaning connection 5 for gas cleaning, and an indicator line 6 for supplying power to the radar measurement probe 3 and for transmitting measurement signals. It can also be seen that the line 6 is connected to the evaluation device 15 which displays or represents the height of the surface 11...

Abstract

A method and an installation for the continuous checking and regulation of the level of the surface of a slag bath in an ESR installation with short slidable molds. For the continuous measurement of the position of the surface of the slag bath, the method employs a radar beam emitted by a radar measuring probe and directed approximately vertically onto the surface.

Description

technical field [0001] The present invention relates to a method and apparatus for continuous detection of slag height in electroslag remelting equipment with short slidable dies. Background technique [0002] In electroslag remelting plants with short slidable dies (also known as "ESR plants"), the height of the slag line, ie the height of the molten metal line, must be kept approximately constant relative to the upper edge of the water-cooled die to avoid the equipment Thermal overload or damage has occurred. Depending on the type of equipment, this is achieved by the fact that, depending on the melting rate of the ingot, the remelted ingot is withdrawn continuously or in steps downwards from the mould installed in the stationary position, or the ingot is assembled in a fixed Pull the mold upwards when it is on the substrate. In both cases there is relative motion between the mould walls and the surface of the ingot to remove the ingot down from the mould. [0003] Sinc...
