Description

Galvanized pot inductor corrosion damage early warning device

Technical Field

The utility model relates to a supplementary field of continuous sheet metal production facility, concretely relates to galvanized pot inductor corrosion damage early warning device.

Background

Most of the continuous hot galvanizing production lines for strip steel adopt a power frequency cored induction ceramic zinc (aluminum zinc) pot, which consists of a furnace body, a furnace cover, an inductor, electrical equipment and other main parts. The main furnace body of the zinc pot is a container for containing zinc liquid and carrying out zinc plating, the bottom of the furnace body is arc-shaped and is vertical to the furnace wall, a rectangular furnace throat is reserved for refractory bricks in the furnace body and is connected with the inductor, and the inductor is upwards inclined by 30 degrees and is arranged around the zinc pot and uniformly distributed.

The inductor adopts a high-power jet flow type detachable air-cooled inductor, mainly comprises two parts, namely an induction element (comprising an iron core and a primary coil) and a molten channel (comprising a shell and a refractory material), wherein the inductor is the most key part of a zinc pot, a heat source is used for heating molten zinc, and after the primary coil is electrified, the molten zinc circularly flows into the middle of a channel hole shaped like a Chinese character ri built by the refractory material and flows out from two sides under the action of an electromagnetic field, so that the zinc-liquid stirring function is realized.

The normal operation of the melted zinc pot needs to ensure that the inductor supplies power normally and is provided with an emergency generator set. The zinc-plated pot and the aluminum-zinc plated inductor can be used for about 10 years and 5-10 months respectively under normal conditions, and at the moment, the zinc leakage is caused because the refractory materials of the molten channel immersed in the zinc liquid at 460 ℃ are most easily corroded and damaged, so that the primary coil of the inductor is short-circuited and is open-circuited after heating. This is a possible occurrence at any time and therefore has a great uncertainty, whereas conventional production facilities do not have an alarm device and therefore cannot detect and deal with problems in a timely manner.
