Sintering furnace from the tropical, sintering zone, cooling zone is complete. Pressed powder from the preheating zone, through sintering zone, outside the cooling zone is cooled from the back. Preheating zone, pressure powder through heat release within the lubricant. Sintering zone: keep a certain amount of time in the specified temperature, combination between the powder. Cooling zone: in the sintering zone heated sinter cooling temperature close to room temperature. Sinter type: as sintering parts production furnace, Meshbelt type sintering and Pusher type furnace is widely used, stainless steel sintered using vacuum sintering furnace Meshbelt type sintering furnace sent from product body to send out on the turn of the stainless steel mesh belt, to automatically into the way. Highest use temperature: 1150 ℃. Put pressure powder in the graphite box, propulsion system one by one into the sintering furnace. Highest use temperature: 1300 ℃.
