APPARATUS FOR PREVENTING UPWARD MOVEMENT OF MATERIAL

摘要

PURPOSE: A device for preventing upward movement of a material is provided to improve the quality of products by preventing a collision between a spray part and a material. CONSTITUTION: A device for preventing upward movement of a material comprises a transfer roller part(50) a first frame part, a first spray part, a first moving part, a control part, and a detection sensor. The transfer roller part includes an electromagnetic roller(51) with an electromagnet unit(52) which generates an electromagnetic force for correcting upward movement of a material. The first spray part is installed in the first frame part and sprays fluid to the material. The first moving part is provided in the first frame part and moves the first frame part from side to side in order to regulate the distance between the first spray part and the material. The control part controls the operations of the first spray part and the first moving part. The detection sensor is arranged at the exit of a finishing mill and detects the material discharged from the finishing mill.
