Acquainted with the instruction __________ / ____________ / "____" _______ 20__

Metallurgy today is an important and actively developing industry, which is experiencing a stable shortage of qualified workers. One of these specialties is the rolling mill.

Description of the profession

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

In production, the main task of the roller is to monitor the equipment, which must always be in working condition, as well as to carry out procedures for the deformation of materials. At the same time, he must monitor the progress of the operation, if necessary, make adjustments to the operation of the equipment. Otherwise, he will not be able to ensure that the product obtained at the output corresponds to 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 adjusting it before use, inspecting the tool, carrying out basic repair work, and replacing parts that have become unusable. If there are technical problems that the specialist himself cannot either eliminate or determine, he must inform the higher management about the problems that have arisen.

In addition, a qualified roller must be able to take readings from instruments and conduct initial quality control of the created product in order to filter out defects.

Where can you learn to become a roller maker?

There are two ways to get this specialty - to enter a vocational school and learn directly at work.

Traditionally, training includes practical and theoretical parts, in the process of mastering which the student not only learns about the types of rolling, the features of working with them, but also gets acquainted with safety precautions at work, the intricacies of the work process. And thanks to the practice at the enterprise, he has the opportunity to see what varieties of the profession there are in order to decide in which particular segment to work in the future.

When mastering a profession in production, there is no opportunity to get acquainted with different options, because the employer decides for himself which specialist he needs. In addition, even if the profession was obtained without an educational institution, the worker may still need to take advanced training courses. It is quite possible that new-style tools will be purchased for production, with which none of the working specialists is fully unfamiliar. Therefore, with any method of mastering this specialty, sooner or later there will be a need to obtain a theoretical base in an educational institution.

In addition, for active development in one's profession and great opportunities for career growth, it is more profitable to receive a special education at the beginning of one's career. We must not forget that in order to obtain an administrative position, you will also need a specialized education. Therefore, today there are special courses at the training centers.

Roller ranks

To date, there are 4 categories in the profession of a roller. Their peculiarity is that the lowest rank is the second, the highest is the fifth:

2nd category– skills of rolling metal parts up to 10 mm thick in cold and up to 20 mm in hot condition;

3rd category– be able to bend edges manually, work with cold metal from 10 to 20 millimeters and hot metal from 20 to 30 millimeters;

4th category- be able to adjust and repair the entrusted tool, also 10 millimeters are added to the thickness of the metal;

5th category- know the device and features of all tools, the quality standards that apply to the finished product.

Individual qualities of the roller

Like many working specialties, the profession of a roller operator requires not only special skills and knowledge, but also a number of individual qualities: the ability to calibrate one’s actions, accuracy and discretion, quick response to an emergency situation, attention to detail, scrupulousness, spatial thinking, the ability to concentrate on work and quickly switch their attention, composure.

In addition, there are also physical requirements for candidates. For example, since we are talking about hard physical labor in dangerous conditions, we need: endurance, sharp eyesight, good coordination and fine motor skills.

Thus, it is strictly forbidden to work in production if there are the following medical contraindications: hearing loss or vision loss, problems with the vestibular apparatus, neuroses, diseases of the cardiovascular system, respiratory organs, stomach, and chronic skin diseases.

Roller salary level

On the territory of Russia, the level of the average monthly income of a roller operator varies greatly: from 17,000 to 60,000 rubles.

The highest salary is received by specialists from the Republic of Altai, the average salary of a qualified specialist is 60,000 rubles. At the same time, the largest number of vacancies is open in the Irkutsk region, where the average salary is 15,000 rubles.

It is also worth noting that in many respects the salary of a specialist is affected by the level of his qualifications, work experience and skills. The higher these figures, the higher the salary will be.

Pros and cons of the profession of a roller

Positive sides professions roller:

    Opportunity for on-the-job training;

    Demand for the specialty;

    Stable work;

    Right to early retirement.

To negative points worth considering:

    Heavy physical labor;

    Serious medical restrictions;

    Harmful and dangerous working conditions for health;

    A small level of income;

    Only men over the age of 18 are hired.

Maintenance of equipment designed to perform such a technological procedure as plastic deformation of metal in a cold and hot state should be carried out by a specialist - a rolling mill. Professional training of roller operators is carried out by special educational institutions.

Main functions

As mentioned above, a roller is a person who, 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 roller monitors compliance with the geometric parameters of the product formed from the workpiece.

In addition, the functions of the roller, which is part of the locksmith and repair team, include preparing the equipment for work, repairing it, replacing worn parts and performing pre-commissioning adjustments. With the relevant knowledge and skills acquired during the training process, a rolling specialist must skillfully operate lifting mechanisms, take readings from control devices, carry out initial quality control of the finished product, and strictly control the sequence of stages of the technological process.

Individual qualities

In order to effectively and without harm to one's own health to cope with such a technological operation as rolling, the specialist who performs it must have a number of individual qualities, which include:

  • caution;

A worker on rollers - a machine for mixing, crushing, grinding something. They are used in the production of rubber, in the flour-grinding industry, in the food industry and in many other places...


Answer from Maxim Pinchuk[active]
The one who does it:
Rolling (rolling) is a technological operation of deformation of sheet material (for example, tin) along a certain direction or radial deformation of a pipe. Often, especially on an industrial scale, rolling of sheets is carried out in forging rolls, and pipes - using a special tool - rolling, from where the name of this operation comes from. Any ductile metals, rubber compounds, plastics are processed. With the help of rolling, finished parts, precise blanks for stamping, etc. are obtained.
Rolling - a tool designed for radial deformation of the pipe in the hole of the tube sheet (collector) of the heat exchanger in order to create a tightly sealed connection. The technological process of fixing pipes using flaring is called flaring. Depending on the design features of heat exchangers and pipe sizes, various types of rolling are used. So, for pipes of small diameter (up to Din. less than 12 mm), rolling of the "T", "ST" and "RT" series are used, for pipes with an inner diameter of 12 to 40 mm, rolling of the "P" and "CP" series are used ( depending on the depth of rolling). For flaring boiler pipes, flaring series "K" (fixing) and series "KO" (fixing and collaring) are used. When fixing extra-thin-walled pipes (for example, 28x0.5 mm), five-roller rolling of the "5R" series is used. As a rolling drive, reversible rolling machines (pneumatic and electric) with automatic torque control are used. The control of the flaring process is carried out according to the formula: Din. after flaring = D int. before flaring + diametrical clearance between the pipe and the tube sheet opening + 10% of the pipe wall thickness. The main technical characteristics of the flare are: 1. The flare range, i.e. the range from the minimum inner diameter of the pipe into which the flare can be inserted to the maximum inner diameter of the pipe by which it can be radially deformed. 2. Expanding depth, i.e., the length of the linear section of the pipe, to which this expansion can be used to radially deform the pipe. In this case, there are flaring both with a fixed flare length and with an adjustable one. The most important quality parameter of flaring is its durability. Roll life is determined by the number of pipe ends of a particular size and material that can be secured in one roll before changing spindles and rollers.
