It connects.Above-mentioned slag hanging groove to be easily formed slag crust on the hot face of copper cooling wall ontology, can preferably protect copper cooling wall.It is above-mentioned
Slag hanging groove can be straight trough or dovetail groove.
As the further preferred embodiment of the present invention, the wearing plate is fitted in the institute between the two neighboring slag hanging groove
It states on copper cooling wall calor innatus face.
The present invention also provides a kind of manufacturing methods of above-mentioned novel wear resistant copper cooling wall, it is characterised in that including following steps
It is rapid:
(1) up, wearing plate is placed on the hot face of copper cooling wall ontology for the heat for making copper cooling wall ontology, and copper is cooling
Wall ontology and wearing plate thereon are fastened on lathe；
(2) stirring-head is mounted on friction stir welding machine, stirring-head includes stirring probe and the shaft shoulder, the stirring probe of stirring-head
It is arranged and is in downward the top of wearing plate；In the lower section of copper cooling wall ontology, setting can heat copper cooling wall ontology
Assisted heating device；
(3) start friction stir welding machine and assisted heating device, drive stirring-head high speed rotation, while assisted heating device is to copper
The heating of cooling wall ontology；
(4) high-speed rotating stirring-head is screwed in into wearing plate after stirring probe penetrates wearing plate from top to bottom and stirs lower probe
Screw in copper cooling wall ontology hot face (usually after the shaft shoulder of stirring-head touches the upper surface of wearing plate, stirring-head no longer under
Move), in the process, the part that wearing plate and copper cooling wall ontology are contacted with stirring-head generates heat under the friction of stirring-head
Amount, under the collective effect of the heat and stirring-head mixing power that are generated by stirring-head friction, wearing plate and copper cooling wall ontology it
Between material generated Plastic Flow and mixing by Thermal-mechanical Coupling；
(5) it exits stirring-head (top for making stirring-head rise to wearing plate) or makes stirring-head and copper cooling wall ontology and thereon
(track of the weld seam formed on demand sends out the copper cooling wall ontology on lathe and wearing plate thereon not for wearing plate relative movement
Raw movement, stirring-head moves in the horizontal direction, or moves stirring-head not, and copper cooling wall ontology and wearing plate thereon exist
It is mobile that horizontal direction is carried out on lathe, is such as moved from left to right), the material for being generated Plastic Flow by Thermal-mechanical Coupling gradually cools down
It solidifies and forms stir friction welding seam, wearing plate is connect by stir friction welding seam with copper cooling wall ontology.

(kg DEG C), 0.39 × 103J/ of copper (kg DEG C)), but since the thickness of stainless steel wearing plate is about 20mm, and copper is cooling
The thickness of wall ontology is about 100mm, causes the thermal capacity of copper cooling wall ontology to be much larger than the thermal capacity of stainless steel wearing plate, separately
It is stirred friction welding technological at normal temperature outside, when may cause wearing plate local melting, copper cooling wall ontology is too fast because radiating
The temperature (thermal conductivity of copper be steel 5 times) for generating Plastic Flow is also not achieved, thus increases in the lower section of copper cooling wall ontology
Electromagnetic induction coil, the high-frequency high-voltage current for allowing high speed to change, which flows through electromagnetic induction coil, can generate the alternation magnetic of high speed variation
, the cutting alternate magnetic force line that alternating magnetic field generates forms vortex on copper cooling wall ontology, and vortex makes on copper cooling wall ontology
Carrier high speed random motion, carrier collides with each other, rubs and generate thermal energy, to play heating copper cooling wall ontology
Effect, solve the problems, such as only agitating friction weldering single source lead to shortage of heat.
As a preferred solution of the present invention, in the step (4), the stirring-head revolving speed is 800-2200r/min.
In a kind of concrete scheme, in the step (5), after completing step (4), stirring-head is made to rise to the upper of wearing plate
Side, the stir friction welding seam of formation are dotted.
In another concrete scheme, in the step (5), after completing step (4), the track of the weld seam formed on demand,
Move the copper cooling wall ontology on lathe and wearing plate thereon not, stirring-head moves in the horizontal direction (such as extremely from a left side
Move right), the stir friction welding seam of formation is strip.
In another concrete scheme, in the step (5), after completing step (4), the track of the weld seam formed on demand,
Move stirring-head not, it is mobile (as from left that copper cooling wall ontology and wearing plate thereon carry out horizontal direction on lathe
To moving right), the stir friction welding seam of formation is strip.

8. the manufacturing method of novel wear resistant copper cooling wall as claimed in claim 5, it is characterized in that: being completed in the step (5)
After step (4), stirring-head is made to rise to the top of wearing plate, the stir friction welding seam of formation is dotted.
9. the manufacturing method of novel wear resistant copper cooling wall as claimed in claim 5, it is characterized in that: being completed in the step (5)
After step (4), the track of the weld seam formed on demand moves the copper cooling wall ontology on lathe and wearing plate thereon not
Dynamic, stirring-head moves in the horizontal direction, and the stir friction welding seam of formation is strip.
10. the manufacturing method of novel wear resistant copper cooling wall as claimed in claim 5, it is characterized in that: in the step (5), it is complete
After step (4), the track of the weld seam formed on demand moves stirring-head not, copper cooling wall ontology and thereon resistance to
Nog plate carries out horizontal direction movement on lathe, and the stir friction welding seam of formation is strip.
