REBAR Straightening Machine Operator

Role & responsibilities

Based on the provided technological instructions, the procedure for the straightener of rolled products and pipes includes the following steps:

1. **Preparing for work**

• Ensure that the equipment (straightening machines, presses, control systems) is in good working order.

• Check the availability and compliance of personal protective equipment (PPE).

• Read the label on the pipe package: check the steel grade, dimensions, and the presence of a pipe passport (if required).

• Make sure that the pipes have undergone heat treatment and cooled to ambient temperature (straightening hot pipes is prohibited).

2. **Control of incoming pipes**

• Check the curvature of the pipes (deviation from straightness should not exceed permissible values).

• Measure the outer diameter of 23 pipes from the package using an MK type micrometer in three sections (at the ends and in the middle).

• Make sure that the pipes have no cracks, flattened heads, or surface defects.

3. **Equipment selection and setup**

• Depending on the type of pipes (round, profile, thin-walled, thick-walled), select the appropriate correct machine or press:

• Cam presses (for example, K107) - for preliminary straightening.

• Hydraulic presses (for example, P418V) - for straightening pipes of various profiles.

• Roller straightening machines (for example, 20-102, for preliminary and final straightening.

• Roll straightening machines (for example, " Reika ", VRM-35) - for final straightening.

• Set up equipment:

• Install the appropriate stamps, rollers or rolls.

• Adjust the distance between the supports, the force, and the angle of the rolls.

• Check the cleanliness and serviceability of the rollers (clean with sandpaper if necessary).

4. **Pipe straightening**

• Set the pipe in the machine:

• For pipes with clogged heads - with the clogged end first.

• For stainless steel pipes - with cut off heads.

• On the " Reika " frame - open end forward.

• Make sure that the pipe is laid with the concave part down (for cam presses).

• Perform the edit in one pass. If necessary, re-edit after adjustment.

• Monitor the process using an ammeter (for pipes according to TU 14-3R-197).

5. **Quality control after editing**

• Check:

• Absence of defects (dents, waves, ovality, spirality).

• Compliance of the outer diameter with the requirements of regulatory documents.

• Straightness (curvature) using a straightedge and feeler gauges.

• Measurements should be carried out:

• On the first 2-3 pipes during tuning.

• Periodically on every 1020 pipes.

• On the last pipe of the party.

6. **Resolving inconsistencies**

• If defects are detected (see tables 4.3.1 and 4.4.2):

• Adjust the force, roll offset, straightening speed.

• Replace or clean the rollers.

• Check and replace the wiring.

• If it is impossible to eliminate the defects, send the pipes for repeated heat treatment or repair.

7. **Documentation and delivery**

• Write in the log:

• Date, shift.

• Pipe sizes, package number.

• Number of straightened pipes.

• Comments on quality.

• Return the label to the package after editing.

• Transfer the pipes to the next operation (cutting, inspection).

Safety requirements:

• Use PPE: special clothing, protective glasses, gloves.

• Do not clean the rolls while the equipment is operating.

• Do not touch rotating parts of the equipment.

• Observe the operating rules of the machines (see section 2 of the instructions).

• Immediately inform the master about any malfunctions or accidents.
