Vacuum degrease sinter furnace

Usage

It used for dewax and sinter of powder metallurgy products, metal injection products, stainless steel, hard alloy, high alloy, high proportion alloy, ceramic material.magnetic material. May realize the dewaxing,  pre-heat, the sinter and the quick freezing production working procedure in the identical furnace body disposable completes; Because it stop the product repeatedly removal, the heating and cooling bring the product quality accident, reduces the labor intensity, reduces the production cycle, enhances the production efficiency.

Feature

Evenly heat and reliable heat insulation and temperature mearsure
     Reasonable heat structure, good material to make sure the temperature euniformity in vacuum condition. Use famous brand temperature measure component, accuracy temperature measure.
Strong dewax effective
     Uses the degreasing pressure-tight box and catches the wax, does not have the fire walls, the heat shield and the heating element pollution, the degreasing and the collection wax is more effective, the special-purpose pressure-tight box is advantageous to the improvement furnace temperature uniformity.
The directional airstream degreasing, in the strengthened degreasing effect, the furnace have non-dead angle for wax, the degreasing are completer.
Furnace internal pressure control, realization negative pressure sinter, suppression metal volatility, improvement product compactness and quality.
      Complete steam dewax system
Equip with unique steam dewax system, to eliminate wax.
Advanced automatic control and reliable safe link
Uses the computer realization temperature, the movement process completely automatic control, PLC realizes safely chain-like, has the overpressure, the ultra warm water temperature higher acousto-optics has reported to the police and the chain-like function.
       High effective fast cooling system
       Has the internal recycling fast cooling system, the highly effective heat transfer technology multi-directions blow fast to the work piece, cooling even.Circulates fast cooling system compared with outside model, also has the occupying a land area of to be small, the area is small, the starting temperature is high, vacuum speed of pumping quick and so on merits.

Structure

A vacuum degreasing sintering furnace have vertical  type and horizontal-type two kinds; According to the furnace temperature height and the customer technological requirement, uses the graphite either the molybdenum or the tungsten as the heating element and the heat shield. Heating element separable arranges, various areas control warm, the programmable PID adjustment independently. The chamber may the whole emigration, be advantageous for the maintenance.Disposes the special-purpose pressure-tight box and the multistage water cooling butterfly piece type catches the wax, uses in the degreasing and the collection wax. Provides the carrier gas degreasing installment, may pass over the carrier gas adjustable to the stove in, the gasification current capacity.Supposes the internal recycling cooling system, may accelerate in the stove the material to cool, reduces the action cycle, favors improves the product quality and the working efficiency.
