HZL: Automation of molten metal transfer

Employees at the Pantnagar Metal Plant silver refinery had been manually transferring hot molten metal between furnaces, essentially putting them ‘in the line of fire’. The automation of this process was an urgent requirement.

Before this, the process involved multiple employees working close to furnace mouths, and sometimes needing manual intervention in handling the molten metal.

After automation, employees no longer have to operate the molten metal transfer system manually. The risk of a spillage of molten metal has been drastically reduced, along with dust fume emissions during metal transfer, and automated lock functions exist on all stages of the process. The systems operator now oversees activities remotely, at a safe distance away from the furnace.
