Cast Belt Hardening Furnaces
Over the past 50 years, Williams Industrial Service, Inc. has been designing and building high-performance industrial furnaces for the heat treating market. Cast belt furnaces are designed for heavy loading and large parts.
Our sizes range up to 6,000 lbs./hour and are designed for maximum performance and offering the latest features in the industry. Williams cast belt furnaces are used for hardening, carburizing, carbonitriding, annealing, normalizing and isothermal annealing.
Below are some of the highlighted features for Cast Belt Furnaces:
Benefits of the Cast Belt
The cast belt design has some advantages especially when it comes to loading. Our cast belt furnaces are designed for loading up to 45 lbs. per square foot compared to a mesh belt which is designed for 20 lbs. per square foot. In addition, a cast belt typically lasts approximately 3 to 5 years compared to a mesh belt which typically needs to be replaced within a year.
No Part Loss or Mixing
One of the biggest challenges with Belt Furnaces is part loss and/or part mixing. Due to the geometry of certain parts, they can roll off the side of the belt or get hung up in the quench chute area causing parts to get lost inside the furnace or mixed with other parts. A cast belt has side flights built into the belt to prevent parts from rolling off the sides.
High Efficiency Heating Systems
Williams primarily uses single ended SIC radiant tubes in many sizes that can be electrically heated or gas fired. When properly maintained, tube life expectancy exceeds 15 years. With this configuration, if one eventually does fail the temperature uniformity is not affected. This keeps the furnace in CQI9 compliance and maximizes up-time performance.
Drive System
Our design includes driven return rolls and automatic clutching for precise ratio control to reduce friction on the belt for improved life.
SCADA Control System
Williams offers a fully automated, state of the art control systems. This provides our customers with complete traceability of the parts including enhanced data collection and reporting capabilities.
