It is divided into the unit area of more than 2 pieces, in every block unit region, is equipped with heater and temperature sensor.
As preferably, heater place plane is equal to the distance on heat screen surface, and heater place plane arrives
The distance of hopper tank surface is equal, be distributed in after the heater bending in unit area hopper and heat screen it
Between space in.
As preferably, hopper is square hopper, and hopper is provided with plate and the corner bracket for gripper shoe, and corner bracket is fixed
On hopper medial wall.The cross section of hopper is square so that it is internal each point temperature distribution evenness is more preferable.
Corner bracket is identical with common angle shape.
As preferably, also including stainless steel frame and insulated column, heat screen is fixed on inside stainless steel frame,
Insulated column is also secured on stainless steel frame, and insulated column top is provided with hook, and heater passes hook.
As preferably, also including support column, be fixed on furnace tube and support on seat bottom support column, hopper is fixed
On support column top.Support column quantity is multiple.Insulated column is fixed through heat screen with stainless steel frame.
As preferably, the material of support column and corner bracket is molybdenum, TZM alloy or molybdenum-lanthanum alloy.
As preferably, hopper is molybdenum, TZM alloy or molybdenum-lanthanum alloy with the material of plate.Molybdenum, TZM alloy
Or the stable chemical nature of molybdenum-lanthanum alloy, is at high temperature difficult to react with other metals, and heat conductivity
Good, indeformable.The heat screen reflection heat that distributes of heater is to the tank surface of hopper.
As preferably, heater is molybdenum heater or heating element of tungsten.
As preferably, hopper is provided with air inlet and venthole.Current-carrying gas is filled with air inlet by conduit,
Flow through sintered products surface, make the binding agent steam on sintered products surface converge to give vent to anger together with current-carrying gas
Discharge hopper at hole, enter in pipeline degreasing system.Avoid original metal sintering stove stove endogenous cause of ill not expect
Case, binding agent affects sintering problem in running about and polluting stove.
This multi-region temperature-conditioned metal thermal field sintering furnace has good temperature homogeneity: 1. arrange hopper, plate, a side
Face makes radiations heat energy can be directly transferred to plate by hopper, is more directly conducted heat to by plate place onboard
On product, the thermal capacity in metal thermal field sintering furnace is also greatly increased, the fluctuation of thermal losses in minimizing stove.2.
Heater bending is used the most equidistantly to be evenly distributed on square metal hopper surrounding, point multi-portion heating, each district
By thermocouple monitoring temperature control, solve metal thermal field sintering furnace stove endogenous cause of ill heat leakage and seriously cause each point in stove
The problem that the temperature difference is bigger.3. metallic insulation screen, hopper all use square structure, make heat screen and heater and
Hopper all keeps equidistantly radiating, and more ensure that the temperature homogeneity of each point in hopper, meanwhile, square metal
The design of heat screen, makes the distance between heat screen and furnace wall strengthen, heat and the biography being connected with cooling water jecket
Pass space to strengthen, decrease the thermal losses of heat screen self.This utility model solves of the prior art
The problem that in metal thermal field sintering furnace, temperature distributing disproportionation is even, may further be used to sinter in addition to conventional products similar titanium,
The product that titanium alloy etc. are high to sintering temperature distributing homogeneity, has the most progressive.
