Gietart Shot Blast Machine

Steel Section Processing Continuous Thermal Imaging System

In April 2007 the BSS Bradford facility suffered a catastrophic failure. The Shot Blast machine caught fire and the resulting damage was so serious that the machine was decommissioned. Loan equipment was quickly acquired until the machine could be replaced, but nonetheless, damage costs were estimated at over £300,000.

Whilst the exact cause of the fire could not be ascertained, the consensus was that a fire hazard (in the form of a hot ember) had ‘stuck’ to a piece of steel at some point during in the pre-heat stage.

It was following this incident that BSS called on the expertise of DMS to design a solution that would prevent a similar event from happening in the future.

A system was developed, installed and commissioned during 2007. In April 2008 the continuous process line at Barrett Steel Services Bradford plant came to an abrupt halt. Closer inspection by the line operator revealed that ‘MachineGuard’ and the thermal scanning device had signalled an alert and automatically stopped the roller conveyer drive.

The operator quickly discovered a hot ember attached to the steel. The offending item was removed and the process line restarted.
