FAQ

For about Steel bar counting system

Our machine is automatic and will be installed in the middle of the third chain. The workflow is as follows:

1) The machine starts counting when the rebar is transferred to the third chain and passes through our machine counting area.

2) When the calculated number of bars is close to the target number, the system will send a chain deceleration signal to your PLC, and your PLC will control the third chain deceleration speed.

3) When the calculated number of reinforcing bars reaches the target number, the system will send a stop signal to your PLC, and your PLC will control the third chain to stop.

4) Counted rebar and uncounted rebar will stop at the rebar area, then a rebar line will appear, our machine will split the counted rebar and uncounted rebar.

5) After the steel splitting process, the next cycle will start.

LMM Answer: The annual production capacity for rolling 12mm rebar in a Chinese steel mill exceeds 1 million tons. Our machines are still running fine.

LMM Answer: When rolling bars of different diameters, the chain speed is the same, but our technicians will adjust the chain speed of each segment to make the machine match the production perfectly and achieve the best use effect.

That said, the speed of each chain is adjustable, especially for the third and second chain.

(Our machine is mounted on the third chain, this is your workshop site situation)
