<p>Make: US Smelting<br/>Model: R4B Rotary Furnace<br/>Condition: used, Overall in great shape</p>
<p>3 Furnaces Available<br/>-Proven high-temperature performance and copper-melting efficiency<br/>-Seller available for on-site consultation during setup to assist with installation and operation<br/>-Willing to arrange a conference call with serious prospects to discuss setup, operation, and any additional questions</p>
<p>-Castable refractory lining (preferred by us due to in-house casting expertise)<br/>-Castable linings typically wear out twice as fast as fire brick linings. For those less experienced with casting refractories, manufactured fire bricks are usually the preferred option.<br/>- $150,000 invested in liner fabrication<br/>-Construction: Built with a metal frame, sheet metal, and insulation around the furnace<br/>-Curing: Achieved ~90% of the recommended 40-hour temperature step-up curing schedule</p><br/><br/><p><b>Furnace Overview: </b></p><ul><li>Slag pots: ~250 Gallon per pot </li><li>Ingot Pours (used): 225 Silver </li><li>Pot Capacity: Cast iron pots can hold up to 1,000 lb molten copper - buyer should determine ideal working load for their process </li><li>Fuel system: neutral gas fired at 15 million BTU/hr </li><li>Max temperature: Reached <b><!--StartFragment-->3,000 °F </b>in operation; capable of melting copper efficiently addition fuel sources can be added for optimized melting environments </li><li>Combustion design: Gas and air mixed in the blower housing / plenum before entering chamber. this ensures a thorough mix and a scattered flame for even thermal distribution throughout the chamber</li></ul><p><b>Controls: </b></p><ul><li>Rotation Control </li><li>Throttle Control</li><li>Emergency Shut off </li><li>No Full automated control panel installed - furnaces were always attended during operation (<!--StartFragment-->Less maintenance, but buyer may add automation if desired.)<!--EndFragment--> </li></ul>
