Description
Technical field
The present invention relates to a kind of shot blast room backplate steel, especially a kind of manufacturing method of middle alloy abrasion resistant steel.
Background technology
Shot-blasting machine is to be sprayed bullet high speed using high-speed rotating impeller head, and bullet is made to have certain kinetic energy, high speed
The bullet of linear motion directly impacts on the surface of the workpiece, and to remove the rusty stain of workpiece surface, but shot-blasting machine is carrying out ball blast
During have bullet and beaten in the chamber body of shot-blasting machine around workpiece, the bullet of high speed can punch chamber body over time, because
This is usually laid with backplate in shot blasting machine chamber body in the prior art, and existing backplate type is relatively more, generally uses rich chromium cast iron
Or manganese steel plate, but in the bullet for being faced with high speed injection, existing backplate keeps its intensity still inadequate due to problem of materials
Good, service life is not grown, therefore will be replaced after a period of use, is thus not only caused the waste in cost but also is indulged in
It delays work the phase, influences production efficiency.
Invention content
A kind of the technical problem to be solved in the present invention is to provide wearabilities good, strong shock resistance and it is with long service life in
The manufacturing method of alloy abrasion resistant steel.
In order to solve the above-mentioned technical problem, the manufacturing method of middle alloy abrasion resistant steel of the invention, includes the following steps：
A, dispensing：By weight percentage, by following chemical composition dispensing, carbon 1.80~3.20%, silicon 2.3~3. 50%, nickel
1.7~2.5%, manganese 0.8~1.0%, chromium 3~5%, molybdenum 0.9~1.2%, tungsten 0.9~1.8%, silicon 2.1~3.2%, vanadium 0.5~
0.8%, boron 0.7~1.2%, surplus is iron；
B, melting：By melting stove evacuation so that the pressure in smelting furnace is 4.2~4.7Pa, and dispensing obtained by step A is put into
Vacuum melting furnace carries out melting；
C, it pours into a mould：The solution that step B is obtained is poured into a mould in sandbox, pouring temperature is 2000~2100 DEG C；
D, cooling：After the casting that step C is obtained is by 25~35 min of air-cooled cooling, by 15~30min of cooling by water,
Then 10~20 min are condensed by condensing unit；
E, it anneals：1100~1170 DEG C are heated to after casting after cooling in step D is carried out polishing processing, heat preservation 45~55
Min then heats to 1250~1350 degrees Celsius and keeps the temperature 90~120 minutes, later quick water cooling；
F, it quenches：Cast member is heated to 800~950 DEG C to quench, is tempered in time after quenching, temperature 400
~420 DEG C.
In the step B, when melting, smelting temperature is 1350~1550 DEG C, and smelting time is 55~60 min, goes out furnace temperature
Degree is 1000~1250 DEG C.
In the step C, casting fully solidifies 15~25 min in sandbox after cast.
In the step F, the cool time is 2~5h.
Compared to the prior art, the invention has the advantages that:
Due to rationally defining the content of carbon and specifically defining the ratio between chromium, nickel and carbon, at the same time, select to close
The other materials ingredient of suitable ratio, and melting is carried out after extracting vacuum, thus make the uniformity that its solution dissolves good, in addition,
Cast postcooling is gradually cooled down by three kinds of modes, ensure that the quality of casting, and the backplate thus produced has very hard
Degree, it is often more important that also there is good toughness, make it have the performances such as wear-resisting, shock resistance, meet ball blast in the process to machinery
Being required for performance, extends service life, in addition, treatment process of the present invention, using high wind be quickly cooled down with
And rational quenching technical improves alloy structure performance, finally makes its hardness HRC85~95, impact flexibility is good, comprehensive mechanical
Performance is good, so that manufactured product has been reached wear-resisting and moderate blow performance requirement, service life is 3~5 times of potassium steel.
