Abstract
The invention discloses a kind of manufacturing methods of antifriction alloy steel panel.It includes the following steps：A, dispensing；B, melting：By melting stove evacuation, dispensing obtained by step A is put into vacuum melting furnace and carries out melting；C, it pours into a mould；D, cooling：After the casting that step C is obtained is by 35~45 min of air-cooled cooling, by 55~75 min of cooling by water, 30~35 min are then condensed by condensing unit；E, it anneals；F, it quenches：Cast member heating is quenched, is tempered in time after quenching.It has the advantages that:Since the antifriction alloy steel panel of the present invention has selected suitable material extremely proportion relation, and carry out melting after extracting vacuum, thus make the uniformity that its solution dissolves good, cast postcooling is gradually cooled down by three kinds of modes, the quality that ensure that casting, the backplate thus produced have good hardness, intensity and toughness, can reach good mechanical performance, amalgamation is good between various composition, and alloy structure performance is good.
Description
Technical field
The present invention relates to a kind of manufacturing methods of abrasion-resistant stee, especially a kind of to be applied to the indoor wear-resisting alloy steel shield of ball blast
The manufacturing method of plate.
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 protective plate in shot blasting machine chamber body in the prior art, and existing protective plate type is relatively more, generally uses Gao Ge
Cast iron or manganese steel plate, but in the bullet for being faced with high speed injection, existing backplate makes its intensity due to material technology problem
Still not good enough, service life is not grown, therefore will be replaced after a period of use, and the wave in cost is thus not only caused
Take and delay the duration, influences production efficiency.
Invention content
The technical problem to be solved in the present invention is to provide a kind of wear-resisting, shock resistance and wear-resisting alloy steel with long service life shields
The manufacturing method of plate.
In order to solve the above-mentioned technical problem, the manufacturing method of antifriction alloy steel panel of the invention, includes the following steps：
A, dispensing：By weight percentage, by following chemical composition dispensing, carbon 1.6~1.9%, silicon 0. 70~0. 90%, manganese 13
~16%, chromium 6. 5~8.5%, nickel 0. 6~0. 9%, molybdenum 0. 5~0. 7%, titanium 0.15~0.25%, silicon 0.3~0.5%, phosphorus
0.05~0.07%, surplus is iron；
B, melting：By melting stove evacuation so that the pressure in smelting furnace is 3.2~4.2Pa, 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 1730~1850 DEG C；
D, cooling：After the casting that step C is obtained is by 35~45 min of air-cooled cooling, pass through cooling by water 55~75
Then min condenses 30~35 min by condensing unit；
E, it anneals：800~980 DEG C are heated to after casting after cooling in step D is carried out polishing processing, heat preservation 15~20
Then min carries out Slow cooling；
F, it quenches：Cast member is heated to 850~900 DEG C to quench, is tempered in time after quenching, temperature 350
~380 DEG C.
In the step B, when melting, smelting temperature is 1380~1520 DEG C, and smelting time is 55~60 min, goes out furnace temperature
Degree is 1100~1250 DEG C.
In the step C, casting fully solidifies 45~55 min in sandbox after cast.
In the step F, the cool time is 6~9h.
Compared to the prior art, the invention has the advantages that:
Since the antifriction alloy steel panel of the present invention has selected suitable material extremely proportion relation, and carried out after extracting vacuum
Thus melting makes the uniformity that its solution dissolves good, in addition, cast postcooling is gradually cooled down by three kinds of modes, ensure that casting
The quality made, the backplate thus produced have good hardness, intensity and toughness, can reach good mechanical performance, in addition,
Manufacturing method of the present invention, amalgamation is good between making various composition, and alloy structure performance is good, and then makes manufactured product
Wear-resisting, shock resistance is reached, service life is long, has better economy and comprehensive mechanical performance.
