Problems solved by technology

[0005] For the traditional continuous molten metal plating equipment that is provided with a radiant plate temperature maintaining chamber, because its plate temperature maintaining chamber is radiant, the responsiveness of the temperature control of the strip-shaped steel plate is poor, and, if the strip-shaped steel plate is to be achieved If the required temperature accuracy is not required, the plate temperature holding chamber will become too long, and there is a problem that a large installation space is required.

Embodiment Construction

[0010] Embodiments of the present invention will be described below with reference to the drawings.

[0011] Fig. 1 shows the continuous molten metal plating equipment 1 of the present invention, and this continuous molten metal coating equipment 1 is for example arranged behind the heating zone of the annealing furnace, the back of the cooling zone, has the strip-shaped steel plate S, such as cold-rolled steel plate to press continuously The plate temperature holding chamber 11 , the plating solution tank introduction space 12 , the mouth 13 (snaut) and the plating solution tank 14 pass sequentially.

[0012] In the inside of the plate temperature maintaining chamber 11, a plurality of nozzles 21 arranged laterally at intervals are arranged in two rows opposite to each other at intervals above and below the steel plate S in the form of spraying gas to the strip-shaped steel plate S. The gas is forced to convect in the chamber 11 . In addition, the gas circulation channel 22 ...

Abstract

The continuous hot-dip metal plating apparatus (1) comprises a plating tank (14) for accommodating a metal plating bath which is heated and kept to the desired temperature, and a chamber (11) for keeping a strip temperature. In the chamber (11), a gas is sprayed to a steel strip (S) which has been cooled to a temperature capable of being hot-dip metal plated and enters the chamber; the steel strip (S) is made to pass through an atmosphere in which the gas is forcibly convected, and is continuously sent out to the metal plating bath (29); and the above sprayed gas is adjusted to a temperature for holding the steel strip (S) to a suitable temperature for immersing it into the metal plating bath (29) to hot-dip plate it.

Description

technical field [0001] The present invention relates to continuous molten metal plating equipment for continuously immersing strip-shaped steel plates in a metal plating solution for molten metal plating. Background technique [0002] Conventionally, there is known a continuous molten metal plating facility installed after a heating zone or a gas forced convection cooling zone. In addition, in the case of continuously immersing the strip-shaped steel sheet in the metal plating solution to perform continuous molten metal plating on the strip-shaped steel sheet, it is preferable to adjust the temperature of the strip-shaped steel sheet entering the metal plating solution with high precision. The temperature of the metal plating solution is substantially the same. And, generally, for the temperature unevenness in the longitudinal direction and the temperature unevenness in the width direction of the strip-shaped steel plate entering the metal plating solution, about ±5°C is th...
