Roller operator of a hot rolling mill. profession roller

Description of the profession

A roller is a worker who knows how to work with a special tool to deform sheet material. This procedure is called rolling, as is the apparatus itself with which it is carried out. It is from them that the name of the profession comes.

In production, the main task of a roller is to monitor the equipment, which must always be in working order, and also to carry out procedures for deforming materials. At the same time, he must monitor the progress of the operation and, if necessary, make adjustments to the operation of the equipment. Otherwise, he will not be able to ensure that the resulting product meets the specified parameters.

Since the roller is responsible for the performance of the tool entrusted to him, his responsibilities also include preparing the equipment and setting it up before use, inspecting the tool, carrying out basic repair work, and replacing worn-out parts. If technical problems arise that the specialist himself cannot either eliminate or determine, he must inform senior management about the problems that have arisen.

In addition, a qualified rolling operator must be able to take readings from instruments and carry out initial quality control of the created product in order to screen out defects.

Main functions

As mentioned above, a roller is a person who, by operating specialized equipment, controls the process of hot or cold deformation of a metal workpiece. Carrying out such control and promptly making adjustments to the operating modes of the device, the rolling operator monitors compliance with the geometric parameters of the product formed from the workpiece.

In addition, the functions of a rolling operator, who is part of a metalworking and repair team, include preparing equipment for work, repairing it, replacing worn parts and performing pre-start adjustment. Having the appropriate knowledge and skills acquired during the training process, a rolling specialist must skillfully operate lifting mechanisms, take readings from control instruments, carry out initial quality control of the finished product, and strictly control the sequence of stages of the technological process.
