Description: Ultra High Temp Centorr Vacuum Industries Series 3600 Model 4236-30T 30 Ton Vacuum Induction “Hot Ejection” Type Hot Press Arguably this Vacuum Hot Press is one of the Highest Temperature Furnace Ever Built, Capable of Operating at Temps > 3800 C (This is not a typo, this is degrees C, not F). Using the Correct Hot Zone Materials and Set Up. This System has been routinely run for Extended Periods of Time (>40 Hours) at Temps over 2,200C/~4,000 F, and Typically Only Running ~15 KW RF Power. This unit has extensive manuals and documentation. This Hot Press has two Hydraulic Cylinders Making it Possible to Push The compacted Sample Out of the Hot Press Die and Shield Pack for rapid Process Cycle Times. It also is Much Easier to Load a Hot Injection Press as you can use the Bottom Press to lower the loaded Compaction Die into the Hot Zone. The Vacuum System on this VHP Consists of an LN2 Trapped Varian VHS-6 Diffusion Pump Roughed by an Alacatel 2063 C 57CFM Direct Drive Rotary Vane Pump. It is Plumbed having an “All Stainless-Steel” Foreline with Norcal Control Valves. The Main Chamber is Isolated with a 6” ASA VRC Aluminum Right Angel Valve with an Integral KF-40 Roughing Port. No Holding Pump is Included. This system Has Complex Controls with Many Options. The System Includes Two Types of Pyrometers (Mikron & Ircon Types) and has Thermocouple Pass throughs for Type-C (5W26 Type) Tungsten Rhenium and Type-S Control Thermocouples. It was normal for us to consume a W526 T/C as needed to get our last NIST Traceable Emissivity Correlation at ~2,300 C before switching over to running closed loop on the Pyrometer. The System has a Honeywell Model DCP-7700 Ramp Soak Controller with a Type-C Range Card (and this is rare!!) and a Model DRP-1500 Process recorder. This System includes Two Different Ircon Brand Two Colorrometers, and a Mikron One Color Pyrometer that can be used as a Check. There is No over Temp System That Works Reliably at over 2,000 C, but the RF Power Supply Does Have its Own Over Temp Protection System Included. Vacuum Instrumentation Includes a Varian Model 843 Ion Gage and a Granville Phillips (GP) Model 307 Multi Gage Controller and a GP Model 275 Convectron Tube Digital Readout for higher pressure (1-1000 Torr) process vacuum levels. As this System makes use of Graphite Felt Insulation Products and Other Specialty Ceramic Potting Compounds in the Hot Zone, This System Usually only pulls mid 10-5 Torr Vacuum Levels Following an Overnight “Warm” Pumping Interval. This System Has a Pasadena Hydraulics Inc. Hydraulic Power Pack which uses Parker Pilot Control Valves, and a Model PACV Type 0-3000 Hydraulic Pump. Max Pressure is controlled using a Moog Model 760-102A Servo valve, which can be directed to move either ram in controlled fashion. As this is a Hot Ejection Vacuum Hot Press Both Rams have an Extended Travel Length of ~15 inches, which may also be moved using a Pendant Wand for Quick Furnace Loading. For Heating this System Includes Inductotherm VIP Power Trak Induction Power Supply Model 35-96 (Exact Model Number is: 89-34320-246-1) and includes a Remote Water Chiller That Makes and Uses DI Water to Chill The Power Supply. This is considered a Low Voltage Low Frequency Power “Vacuum Induction Melting” Type RF Supply. The Unit can Deliver 35 KW of RF Power at around 9600 Hz. The Power Supply Plugs into 460 VAC 3- Phase with a 52 amp feed, but rarely runs over 25KW even when running very hot. This System Comes with Three Different Working Coils. We have has several of these VHP’s for sale ton eBay hat are induction heated for ultra-high temperature near-net-shaped compaction of metal, ceramic, and other complex chemistry systems, at temperatures of over 3,500° C. The systems routinely make custom rocket nozzle and missile nosecone parts for advanced military systems, and have a client list that includes most of the prime contractors in the USA. We have substantial experience in making divert attitude control (DACS) system parts, and are the first contractor in North America to ever diffusion bond rhenium metal parts for the SM-3 DACS systems. The systems can also make Ultra-High Temperature Ceramic (UHTC) parts based on mixtures of very high melting point carbides (HfC, TaC) and borides (such as ZrB2, others), stemming from work originally started by MANLABS, and further developed by NASA Ames, and NAVSEA. We have several furnaces that utilize hafnium carbide succeptors that can be operated at over 3,800° C!Of the three induction heated vacuum hot presses. Two are “hot ejection” types that have both rams movable, and run under high vacuum, and one that is “rough vacuum” only and has a single top down acting ram. Both high vacuum units can be run at very high temperatures, up to nearly the melt point of the highest known materials (TaC/HfC mixtures at 3,890 ° C).
