[0023] Instructions for use of this utility model

[0024] 1. Overview

[0025] This instruction manual is intended to guide operators to correctly use the automatic billet turning device to ensure that the device can play its maximum role in the production process. By following this instruction, operators can effectively solve the problem of billet bending during the furnace feeding process and improve production efficiency and product quality.

[0026] 2. Equipment Inspection and Preparation

[0027] Before starting the operation, please ensure that all parts of the automatic billet turning device are intact and have no obvious mechanical failures.

[0028] Check whether the cylinder and its control system are working properly to ensure a stable gas supply.

[0029] Confirm that key components such as lifting cables, fixed pulleys and power units are free of wear or damage.

[0030] Ensure that the gantries on both sides of the roller conveyor are installed firmly and adjusted in the correct position.

[0031] 3. Operation steps

[0032] When the monitoring system detects that there are transversely bent billets in the roller table that affect the entry into the furnace, the operator should immediately press the control button of the cylinder.

[0033] After the cylinder is started, it will provide traction to pull the lifting cable, so that the billet carrier and the billets inside it are lifted to a specified height.
