Property, the most integrative-structures with nitrated steel as raw material of extruder barrel of the prior art, this structure high temperature resistant, corrosion resistance
Can be limited, and with the increase of wearing depth, the hardness of nitrated steel drastically declines, it is necessary to often replacing, greatly increases enterprise
Production cost.
The content of the invention
To solve the problems, such as prior art, the invention provides one kind have super-strong high temperature-resistant, decay resistance and
The dual-metal cylinder body of the extruder of long service life.
The present invention is additionally provided with to solve the problems, such as that prior art uses following technical scheme, including cylinder in cylinder
The disjunctor bushing that inwall is 8-shaped, outer wall is ellipse, the disjunctor sleeve outer surface is excessively connected with cylinder.It is described
Disjunctor bushing inwall is provided with the alloy material that a layer thickness is 2mm.
Preparation technology of the present invention is：
Step one, from the steel pipe that 20 steel or 45 steel are made, it is the Cr powder of 4%-50% that mass percent is added in pipe,
Mass percent is the Ni powder of 5%-90%, and mass percent is the W of 2%-50% for the Co powder and mass percent of 2%-60%
Powder is well mixed.
Step 2, adding the steel pipe of well mixed alloy powder to be put into centrifugal casting die, heating steel pipe is extremely
1200 DEG C -1350 DEG C, melt completely to liquid to alloy powder.
Step 3, makes centrifugal casting die be rotated with the speed of 500-2000r/min along steel pipe axle center, makes liquid alloy equal
Even is distributed in steel pipe inner wall, and thickness is 2mm.
Step 4, will be put into 500 DEG C of moist closet by the steel pipe after spun casting, be incubated 8 hours.
Step 5, the materials in the tube that section is C-shaped are cut into by the steel pipe after insulation by quick-wire-moving linear cutting machine.
Step 6, the materials in the tube that will be made in step 5 are placed on precision grinder, and grinding c-shaped opening face to surface roughness reaches
To Ra≤0.4, materials in the tube inwall is ground to Ra≤0.8.
Step 7, will be made two pieces of c-shaped opening faces of identical materials in the tube relatively, to two materials in the tube junction surfaces and inside in step 6
Shaping is respectively welded, joint portion is welded into 8-shaped disjunctor bushing using common welding, inside by the way of argon arc welding.
Step 8, disjunctor bushing is fitted into the cylinder with the forging molding of disjunctor bushing form fit.
The beneficial effects of the invention are as follows：By the way of disjunctor bushing and cylinder coordinate, disjunctor bushing uses alloy material
It is made, cylinder is made of common iron, for traditional integral cylinder, reduces 90% material cost.And
The present invention substantially prolongs the service life of extruder barrel with superpower wear-resistant, high temperature resistant, decay resistance.
