Cooling Apparatus

Abstract

A cooling apparatus includes a convoying unit and a spraying unit. The convoying unit includes a base and a plurality of rollers. The base includes a feeding end and a discharging end in which a convoying direction extends from the feeding end to the discharging end. The rollers are arranged on the base. Each roller includes a convoying portion. The convoying portion has a diameter which reduces from two ends to a center thereof. Each roller includes a shaft. The shaft has an axle direction which is at a diverted angle to the convoying portion. The diverted angle is 15° to 90°. The spraying unit includes at least one nozzle unit arranged between the feeding end and the discharging end. In this arrangement, a cooling operation can be performed on a rod-shaped steel material that is moving and rotating at the same time, attaining uniform and fast cooling effect.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The application claims the benefit of Taiwan application serial No. 104141192, filed on Dec. 8, 2015, and the subject matter of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present disclosure generally relates to a cooling apparatus and, more particularly, to a cooling apparatus that can perform a cooling operation on a rod-shaped steel material.[0004]2. Description of the Related Art[0005]Heat treatment process is able to change the mechanical properties of a steel material during the processing of the steel material. The heat treatment process includes annealing, quenching and tempering. As an example of quenching, when a steel material is heated to a predetermined temperature, a cooling apparatus can perform a fast cooling operation on the steel material. In this regard, the cooling apparatus can change the metamorphosis of the steel material by controlling the cooling te...
