Description
Technical field
The utility model relates to casting-sinter process mould therefor correlative technology field more particularly to a kind of hard alloy type are long
Nozzle mold for forming.
Background technique
Casting-sinter process combines the feature of casting technique, powder metallurgy, self-propagating high-temperature, mainly for the preparation of Metal Substrate
Composite material.It is damaged by pressure, composite material green compact on the basis of traditional casting technique in cast(ing) surface layer composite layer composite material
Under the action of high-temperature liquid metal, high-temperature chemical reaction, a large amount of ceramic particle of in-situ preparation, TiC, VC etc. occurs.It is in situ anti-
The generation answered, so that composite layer has extremely superior performance, to extend the service life of metal material.
The process flow of casting-sinter process is as follows:
First according to alloyage powder is required, then on press by powder pressing at the green compact with higher density,
Green compact is placed in the casting mold prepared again, finally pours molten metal in people's casting mold.After metal freezing, composite material green compact
It completes around knot and densification process, and metallurgical bonding occurs with casting parent and is integrally formed.It is adopted according to the design feature of workpiece
With the method, surface composite layer can be prepared with a thickness of the workpiece of 3-10mm.In entire forming process, along with following
The progress and completion of process.
1. composite wood section damages by pressure under the action of high-temperature liquid metal, high-temperature chemical reaction occurs, in-situ preparation is largely made pottery
Porcelain particle.Such as TC, VC, reaction in-situ make composite layer with extremely superior performance, e.g., resistance to the making property of high wearability,
Southern high temperature oxidation stability etc..Composite material damages the process that in-situ chemical reaction is completed under high-temperature liquid metal excitation, essential table by pressure
Reveal the feature of conbustion synthesis.During such a, phenomena such as including igniting to composite layer, the transmitting of combustion wave.
Here it is the self- propagating features of casting-sinter process.
2. composite wood section green compact under the action of high-temperature liquid metal, occurs sintering and political affairs densification, makes composite layer
With meeting structure feature required by substrate performance.Burning when prepared by this sintering and densification process and powdered metallurgical material
Knot and densification process are much like.This is the powder metallurgy feature of casting-sinter process.
3. under the action of high-temperature liquid metal, the metallurgical bonding between casting parent occurs for composite material green compact, so that
Composite layer becomes organic whole after casting solidification completion, with casting.Such metallurgical bonding, so that composite material
Layer is under the conditions of bearing huge alternating load, and under high thermal shock, the peeling conditions with parent will not occur.Together
When, the forming of casting body is disposably completed in a manner of liquid forming, this makes casting-sinter process show distinct casting
Feature.And if long nozzle as described in Figure 1 is cast using casting-sinter process, it can be seen from the figure that this each portion of long nozzle
There is differences for the wall thickness and diameter of position, and the green compact for the long nozzle of hard alloy type proposes biggish challenge, if adopting
It with traditional mold and is easy to appear, alloy powder the phenomenon that alloy powder is not compacted occurs in the process of compacting, and demoulding is tired
Difficulty greatly may generate damage to green compact during demoulding, therefore design and a kind of be able to solve the special of above-mentioned technical problem
It is very urgent with mold.
