Dri Feeding Control System

The melt shop is prepared to use cold DRI. The continuous DRI Feeding Control System has already been designed to handle cold DRI and uses number of silos, EM vibro feeders, and few conveyor belts.The capacity of the DRI bins on top of the EAF can be scaled using weighing system when DRI feeding.

ASs a rule, it is common to have the amount needed for one heat or little more.

The cold DRI is received from storage yards at any time as is needed by the EAF. The handling system is designed with enough capacity to have the required amount of DRI and the same is stored before the EAF heat cycle starts.

The DRI storing silos will be installed on load cells. The load cells are of type shear beam or compression. The load cell signal will be summed in JB and connected to batching controller with special extension cable to transmitter modules, transmitter modules will be connected to batching controller. Through which it receives weight of each DRI silo. Provision is there to calibrate for required full scale.

These Transmitter modules are connected on LOCAL bus to the batching controller. The controller is state of the art and designed to handle up to six weigh silos .The controller has 16 digital outputs, 16 digital input and 4 nos. of analog outputs .The Controller has 6a touch screen and inbuilt power full PLC.
