 After furnacing, hot mold assemblies are moved into a cooling station. Because cooling takes longer than rapid heating in the furnace, two cooling stations are typically included for each bottom loading furnace. This configuration provides maximum production capacity for the complete system.
Keith offers several cooling options that can improve the efficiency and repeatability of the cooling process. Water is sprayed on the bottom of the mold in one of several configurations to provide differential cooling of PCD bits. There are also multiple alternatives for controlling cooling temperatures. Cooling bells have a stainless steel interior, and are designed to vent steam and manage condensate.
- Hot mold assemblies can be automatically or semi-automatically moved from the furnace to the corresponding cooling station
- Cooling stations are designed to cool mold assemblies from a starting temperature of 2100 F
- Cooling water is sprayed at specified volumes from under the grid and from the lower interior side walls to accommodate the widest range of bit sizes
- A stainless steel inner liner with an upper vent is standard for long bell service life
 
COOLING CONTROL
- Accurately regulated differential cooling of mold assemblies is standard on all systems to provide high-quality results
- With the standard control system, after establishing and programming the settings for each mold assembly size, unique cooling settings can be selected and duplicated from memory
- An optional closed-loop control system is available to monitor process variables for each cooling cycle, and automatically adjust the system to accurately cool different mold assemblies
- Data logging of cooling bell temperatures is standard to fulfill customer reporting requirements
