Burning

Harrison Steel has two cleaning rooms, one for castings up to approximately 4,000 lbs. and the other for castings over 4,000 lbs.

The operations performed are very similar regardless of which cleaning facility a casting runs through. Each casting produced at Harrison Steel has a defined set of processes it will go through. Process sheets are developed and monitored by the Quality Control Department.

Grinding

Castings begin in the cleaning room by going through 1 of 3 Primary Blast operations. From the Primary Blast castings either begin the excess metal removal process or go to a post heat-treat operation.

Metal removal consists of Burning off the heads, gates, risers and Flamewashing down the riser contacts. Depending on the process sheets, castings will go through a series of welding, grinding and inspection operations and then onto heat treatment.

Harrison Steel has 10 heat treat ovens and 3 quench tanks to aid in meeting material specifications. Most recently Harrison Steel invested over 2 million dollars in a Normalizing Pusher Type Oven with the capability of heat-treating 3,500 lbs. per push. In addition, our newest quench tank is located at the end of this oven.
