Problems solved by technology

[0007] The disadvantage of the above method is that it is relatively difficult to control the process
Although it is possible to utilize the furnace energy by utilizing the (waste) heat of the furnace in the vicinity of the ingot charging device, the heat transfer process is relatively slow, so that accurate and rapid heating of the ingot to be charged cannot be smoothly achieved

Embodiment Construction

[0021] exist figure 1 A device 1 for feeding zinc ingot billets 2 into a molten metal tank 3 is shown in . In a known manner, furnace tuyeres 11 protrude from a molten metal bath 3 in which a metal strip (not shown) to be coated passes. The feeding of the ingot 2 into the molten metal tank 3 is accomplished by means of the conveying mechanism 4 shown. The holding device 6 is a component of the conveying device 4 and holds the ingot 2 to be introduced into the molten metal bath 3 in such a way that the ingot can be immersed in the bath 3 to the desired extent and thus melted.

[0022] The heating unit 5 is an essential component of the device 1 and has self-sufficiently operating heating elements which can operate independently of other system components which cooperate with the device 1 . The heating element is mainly an independent energy supply mechanism, which is not related to other equipment components. In particular, no heat from other furnaces is used to heat the ing...

Abstract

The invention relates to a device (1) for inserting metal ingots (2) into a metal bath (3), in particular zinc ingots into a zinc bath, wherein the device (1) comprises feed means (4) with which an ingot (2) can be fed to the metal bath (3), and wherein the device (1) comprises heating means (5) with which the ingot (2) can be heated to a desired temperature before and / or after its feeding into the metal bath (3). In order to improve the process control, it is provided according to the invention that the heating means (5) comprise at least one independently operated heating element which can be operated independently of other system parts with which the device (1) cooperates.

Description

technical field [0001] The invention relates to a device for feeding metal ingots into a molten metal tank, in particular zinc ingots into a galvanizing tank, wherein the device has a conveying mechanism whereby the ingot can be supplied to the molten metal tank, the device has a heating mechanism which can be The heating mechanism heats the ingot to a desired temperature before and / or during the process of feeding the ingot into the molten metal bath. Background technique [0002] In a hot-dip galvanizing plant, the strip to be coated is guided through a bath of molten zinc alloy. The zinc that is now used for coating is thereby continuously delivered from the galvanizing bath. Therefore, zinc must be added to the tank to maintain a stable liquid level in the galvanizing tank. [0003] For this purpose, a filling device is known, by means of which a metal ingot can be fed into a container containing a metal melt. At this time, it disadvantageously occurs that the tempera...
