Is It Safe When Steel Rebar Production Line Works?
When steel rebar production line works, it is vital to ensure the workers safe. So, is it safe when the steel rebar production line works? What safety devices does the rolling mill have?
Safety Joint
It is installed between the lower screws of the loading rolling machine and the upper and lower roller bearings, and equipped with a protective cover. When the rolling force exceeds the allowable value, the safety joint rupture increases the distance between the roll, which protects the roller. The material of the safety joint is generally used for hard and crispy cast iron. Its strength should be lower than the strength of the rolls and cannot be abused by casting steel or forging steel.
Plum Blossom Set
Plum blossom a shaft, the plum head loaded on the plum blossom head. When the rolling torque exceeds that the torque is allowed, the plum axis sleeve is broken first, thereby protecting the roll.
Joint Axis
The joint axis section is installed at the connection between the axis and shaft of the transmission mechanism. When the motor is overloaded, the sales of the sales in the coupling section are cut off, thereby protecting the motor.
Over-Current Relay and Heat Relay
Over-current relay and thermal relay, located at the power input at the motor. When the input current exceeds the load, it can automatically cut off the power to protect the motor.
All these are used to protect the whole steel rebar production line operating safely. Therefore, it is totally safe when the steel rebar production line works.
