Description

{COVER DEVICE FOR PLATING BATH}

The present invention relates to a plating apparatus for a plating tank, and more particularly, to a plating apparatus for a plating tank which prevents foreign matter from being injected into the plating tank and maintains the plating solution at a constant temperature.

In general, a steel sheet is coated with a zinc-based metal or a metal alloy on its surface for various purposes such as heat resistance enhancement and corrosion resistance enhancement. There are various methods for forming a coating by plating a steel sheet. However, in order to continuously perform a plating operation in a coil state, a method of passing a steel sheet through a plating bath storing a plating solution containing a substance to be plated is mainly used do.

Recently, a sink roll is disposed in a plating tank, a steel plate is immersed in a plating tank in a diagonal direction, and then the direction of the steel sheet in the sink roll is switched from vertical to vertical, The method of the present invention is mainly applied.

On the other hand, the plating bath is a hot-dip coating apparatus for performing plating by immersing the object to be plated, and it is generally kept at a very high temperature because it is heated by a heating means so as to maintain the plating liquid contained therein at a proper temperature.

However, in the conventional plating vessel as described above, the upper portion into which the steel sheet to be cast is inserted is always maintained in the open state, so that the plating vessel is exposed to the air, thereby lowering the temperature of the plating liquid, And the plating quality is lowered due to the introduction of the foreign substance.

When the capacity of the plating liquid contained in the plating vessel is reduced due to the continuous plating operation, a new material, the ingot, is injected. At this time, as the temperature of the plating vessel is rapidly lowered, normal plating operation can not be performed, The time required for heating the plating bath is excessively required until the temperature of the plating bath is raised to the set temperature. This lowers the productivity and lowers the operating rate of the plating bath.
