Sintering furnace

KSF Series is a sintering furnace designed for high temperature sintering, baking and various other sintering service at our own facilities. Our customers benefit from our long experience and extensive knowledge in furnace sintering processing

Special Feature

High Productivity
Our advanced sintering furnace building technology, incorporating a unique heater designed graphite insulation, enables temperatures to be increased very rapidly, and provides a large uniform zone

Fully automatic main closure control
Air-Hydraulic operated lock safety close. One touchoperation of locking/unlocking, lifting/closing can be operated from thecontrol panel and remote control box. A completely automatic bottom exchange system saves when setting and removing the work.

High precision
A digital program controller and thyritor regulator combination gives precise and uniform temperature control.

Reliability
A uniform temperature zone is produced by the use of all round heating and the our unique furnace building technology. Our unrivaled heater design and furnace building technology ensures a long, trouble-free working life and ease of maintenance.

1. THE VESSEL Cylindrical Vessel Orientation - Vertical / Horizontal Rated Vessel Pressure - Full vacuum to 6 bar internal pressure,double walled water cooling jacket. Standard Material - Austenite Stainless Steel. Main Closure - Air - hydraulic operated safety closure. One touch operation of Lifting / Closing can be performed from the control panel and remote control box. Standard feedthru - 1-1" sight glass, 3-High purity copper electric power feedthru., 1-3/4" thermo couple feedthru. 1-4" vac.-high press. gate. (subject to change depends on the vessel size) Special inside surface treatment made hard to be contaminated by organic binder.
	2. THE HOT ZONE Typical KSF Hot Zone assemblies include graphite resistance heating element, thermal insulation shielding,convection barriers, electrical isolations. INSULATION A graphite insulation is used. Access to the hot zone is through a removable top cover. A convection barrier prevents "short circuiting" of the insulation, allowing maximum temperature uniformity to 2200`C
HEATING ELEMENT The three phase heating element is supported by water cooled power feedthroughs Water cooled power feedthroughs carrying high current from the transformer to the heating element. CRUCIBLE SYSTEM The crucible is designed to support a temperature uniformly distributed load up to 2200`C Loading / Unloading of the crucible is performed by air-hydraulic operated automatic work loading system.
	3. WATER CIRCULATION SYSTEM KGPS employes a Closed Drain Cooling Water System which matches your existing plant water system. Includes is an inlet distribution manifold with a pressure gauge and separately valved circuits for chamber, power feedthrough and pumping system. Inlet and Outlet alarmed pressure switches warn both of low water flow rate and high water temperature. Cooling water is distibuted to the chamber, power feedthru, some types of optional pumps, and accessory modules.
4. GAS CONTROL SYSTEM Automatic Inert Gas High Pressure Control System: The inert gas pressure control system can be manually adjusted or programmed to get best sintering condition. To prevent overpressurizing the vessel a relief valve sett point adjustable is provided. The control system employs a 0-2 bar pressure transducer, a modulating valve and a programmable microprocessor pressure controller, with digital read out of pressure. The vessel cover will be interlocked to prevent their being opened when the vessel pressure is above + 0.1bar. 5. PUMPING SYSTEM The pumping system consists of a two stage rotary vacuum pump and a mechanical booster pump, a vacuum manifolding with metal bellows vibration isolation, thermocouple gauge port, mass spectrometer port, automatic vent valve and automatic isolation valve. Option: DP - Diffusion Pump: To provide High vacuum level. Size and speed on request.
6. Control System We propose different models equivalent Controllers from different manufacturer, so you can chose the Controllers matching your existing equipment. Control Cabinet is a 19" Standard Rack Mounted deep cabinet with one hinged front door. The basic control equipment is: Power circuit breaker Voltmeters, Ammeters, Alarm Panel Vacuum gauge readout Pump motor starters PLC Logic Controller (PLC Direct) Graphic Status Display / Operating Console Chino KP1000 Temperature Controller Konics 6 Channel recorder Cabinet Fan & Dust Filter Option: Double door cabinet (Double 19" Standard rack mounted deep cabinet for easy access inside of the cabinet) Pirani gauge with dual setpoints controller for partial pressure (or equivalent instrument) Penning Gauge (Cold Cathode Gauge) with Controller (for High Vacuum) -MKS Double Konics 6 channel recorder (or equivalent) Chino 32 channel recorder Touch Screen Operating Console Industrial Computer & Monitoring Software , Inkjet Color Printer Cabinet Air Conditioning 7. POWER SUPPLY The Power Supply is a saturable core reactor or variable reactance transformer with linear power controller, circuit breaker, undervoltage trip, and water cooled leads. The power supply is transformed from high voltage, low current to low voltage, high current.
