<p>An apparatus for depositing an adherent thermoplastic or thermo-settable powdered marking material on hot products, such as hot steel during the rolling process for identification purposes. The system includes one or more fixed spray guns disposed adjacent to the product flow path from a previous processing operation, such as a rolling mill, for depositing marking powder from a supply source as the product passes. Manually operated or automatic sensing devices trigger the operation of the marking device. An exhaust system removes excess marking powder from the application area for reclaiming.</p> |
