Abstract
The invention discloses a kind of abrasion-resistant stees.The alloying component of its weight percent is:Carbon 2.3~2.7%, tungsten 0.6~0.8%, copper 1.3~2. 5%, rare earth 1.2~1.8%, manganese 0.3~0.5%, chromium 1.3~1.8%, silicon 0.9~1.6%, boron 0.5~0.7%, surplus are iron.Compared to the prior art, the invention has the advantages that:Rationally define the content of carbon and specifically define chromium, ratio between nickel and carbon, the other materials ingredient of proper ratio is selected, thus the backplate produced has unusual hardness, also there is good toughness, it makes it have wear-resisting, the performances such as shock resistance, meet ball blast being required to mechanical performance in the process, extend service life, used treatment process, it is quickly cooled down using high wind and rational quenching technical improves alloy structure performance, finally make its hardness HRC90~95, impact flexibility is good, comprehensive mechanical performance is good, product made of making has reached wear-resisting and moderate blow performance requirement, service life is 5~7 times of potassium steel.
Description
Technical field
The present invention relates to a kind of shot blast room backplate steel, particularly a kind of abrasion-resistant stee.
Background technology
Shot-blasting machine is to be sprayed bullet at a high speed using high-speed rotating impeller head, bullet is made to have certain kinetic energy, at a 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 using rich chromium cast iron
Or manganese steel plate, but in the bullet for being faced with injection at a high speed, existing backplate makes 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
The technical problem to be solved in the present invention is to provide a kind of wearability is good, strong shock resistance and service life length it is resistance to
Grind steel.
In order to solve the above-mentioned technical problem, abrasion-resistant stee of the invention, the alloying component of weight percent are:Carbon 2.3~
2.7%, tungsten 0.6~0.8%, copper 1.3~2. 5%, rare earth 1.2~1.8%, manganese 0.3~0.5%, chromium 1.3~1.8%, silicon 0.9~
1.6%, boron 0.5~0.7%, surplus is iron.
The alloying component of its weight percent is:Carbon 2.5%, tungsten 0.7%, copper 1.8%, rare earth 1.5%, manganese 0.4%, chromium 1.3%,
Silicon 0.8%, boron 0.6%, surplus are iron.
A kind for the treatment of process of above-mentioned abrasion-resistant stee, includes the following steps:
A, stove is entered using room temperature, cast member is heated to 670~790 DEG C, keeps the temperature 50~60 minutes, then heat to 990~
1020 degrees Celsius keep the temperature 60~75 minutes, later quick water cooling;
B, cast member is heated to 650~850 DEG C to quench again, be tempered in time after quenching, temperature for 380~
400℃。
Compared to the prior art, the invention has the advantages that:
Due to rationally defining the content of carbon and specifically defining ratio between chromium, nickel and carbon, at the same time, select to close
The other materials ingredient of suitable ratio, the backplate thus produced have unusual hardness, it is often more important that also with good tough
Property, the performances such as wear-resisting, shock resistance are made it have, meet being required to mechanical performance during ball blast, are extended using the longevity
Life, in addition, treatment process of the present invention, is quickly cooled down using high wind and rational quenching technical improves alloy group
Performance is knitted, finally makes its hardness HRC90~95, impact flexibility is good, and comprehensive mechanical performance is good, and manufactured product is made to have reached wear-resisting
And moderate blow performance requirement, service life are 5~7 times of potassium steel.
Specific embodiment
With reference to embodiment, the abrasion-resistant stee of the present invention is described in further detail.
The abrasion-resistant stee of the present invention, the alloying component of weight percent are:Carbon 2.3~2.7%, tungsten 0.6~0.8%, copper 1.3
~2. 5%, rare earth 1.2~1.8%, manganese 0.3~0.5%, chromium 1.3~1.8%, silicon 0.9~1.6%, boron 0.5~0.7%, surplus is
Iron.
A kind for the treatment of process of above-mentioned abrasion-resistant stee, includes the following steps:
A, stove is entered using room temperature, cast member is heated to 670~790 DEG C, keeps the temperature 50~60 minutes, then heat to 990~
1020 degrees Celsius keep the temperature 60~75 minutes, later quick water cooling;
B, cast member is heated to 650~850 DEG C to quench again, be tempered in time after quenching, temperature for 380~
400℃。
