Product Introduction
CX-HSF series sintering furnaces operate with rough vacuum and protective gases such as Argon and Nitrogen. CX-HSF series can’t operate in an oxygen atmosphere due to graphite crucible and graphite insulation used inside furnace.
The horizontal design with double doors at front and back of the furnace, allows for easy loading and unloading. Three different sizes of this furnace are available in CX-Induction and other sizes can be customized according to client’s requirements.
CX-HSF series use resistance heating method. With maximum temperatures up to 1550 °C and fast cooling (quenching) system, CX-HSF series are suited for a range of sintering and heat treatment processes.
Application
CX-HSF series sintering furnaces are batch-type resistance heating furnaces which are mainly used for sintering process of cemented carbides, tungsten heavy alloys, stainless steel products, high-temperature alloys, magnetic materials, ceramic powder products, and Carbides etc.
General Features
· The furnace is horizontal type with single chamber. The shell and door are water-cooled jacketed. Both the outer and inner layer of the furnace shell is made of SUS304 stainless steel.
· Easy access to all hot zone space via double doors at front and back of the furnace.
· High vacuum pneumatic valves equipped with position indicator in order to automatic control of the vacuum and gas system.
· Use of two sets of gas rotameters in order to control gas flow into the furnace.
· Equipped with pressure transducer in order to monitor pressure level inside the chamber. In case of overpressure, a relief valve will adjust the pressure inside the chamber.
· Fast gas cooling (quenching) accessories include motor, impeller fan, build-in heat sink and ventilator door in heat shield.
Optional Features
· High vacuum system to achieve 10-5 mbar vacuum level
· Dewaxing-Sintering processes in one furnace: Dewaxing system including downward gas stream, hot pipeline with temperature control of pipeline to avoid wax condensation in pipes, condenser for trapping of waxes.
· Gas Purification System
· Cooling Water System
· Distributed Control System (DCS)
· Vertical top loading or bottom loading design
