Abstract
The invention discloses a wear resistant plate. The wear resistant plate comprises the following components by weight: 0.21%-0.25% of C, 1.50%-1.80% of Mn, equal to or less than 0-0.02% of P, equal to or less than 0-0.015% of S, and the balance of Fe. The wear resistant plate is welded to cover the outer surface of the bucket body. The wear resistant plate has the benefits that the mechanic performance is better than that of an existing wear resistant plate, the wear resistance is greatly improved, and the service life of the excavating machine bucket can be greatly prolonged after using the wear resistant plate.
Description
Technical field
The present invention relates to a kind of wearing plate, also relate to the application of using it for power shovel.
Background technology
The pick machine is as one of main machine of engineering machinery, and its equipment can be carried out the functions such as excavation, loading, dismounting, lifting, crawl, piling, boring, soil-shifting.Because it possesses fast, efficient, flexibly, the distinguishing feature such as convenient, be widely used in recent years the construction industries such as industrial plants, covil construction, construction of road and bridge, national defense construction.
Scraper bowl is as directly contacting with soil the device of implementing digging operation, and it directly bears the excavating resistance of soil, therefore requires the main knife plate of scraper bowl and abrading section both to have good mechanical property, and extremely strong wear resisting property is arranged again.
Existing a kind of preparation is for the wearing plate on power shovel, and for Q345B makes, its composition is specially: the content of C is for being less than or equal to 0.20%, the content of Mn is 1.00%-1.60%, the content of P is for the content that is less than or equal to 0.04%, S for being less than or equal to 0.04%, and all the other are iron.The performance perameter of the wearing plate of this composition is: tensile strength is 470-630MPa, and yield strength is 345MPa, and 20 ℃ of impact absorbing energies are more than or equal to 34J, and elongation after fracture is more than or equal to 4%.It is welded on power shovel through overtesting, finds that its work-ing life is short, easily distortion, checking etc., can not meet the application of power shovel well.Therefore, want to extend the work-ing life of scraper bowl, must the better wearing plate of a kind of wear resistance newly developed.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of mechanical property better, the better wearing plate of wear resistance.
The technical solution used in the present invention is such: a kind of wearing plate, and its composition quality per-cent is respectively: the ratio of C is 0.21%-0.25%, and the ratio of Mn is 1.50%-1.80%, and the ratio that the ratio of P is≤0.02%, S is≤0.015%, and all the other are Fe.The performance perameter of this wearing plate is: tensile strength is more than or equal to 1200MPa, and yield strength is more than or equal to 1000MPa, and 20 ℃ of impact absorbing energies are more than or equal to 100J, and elongation after fracture is more than or equal to 10%.
A kind of power shovel, cover scraper bowl main body outside surface by the wearing plate welding the present invention relates to, and is a kind of application to above-mentioned wearing plate.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: the wearing plate before the mechanical energy Performance Ratio is better, and wear resistance also obtains large increase, can greatly extend the work-ing life of scraper bowl for power shovel.
The accompanying drawing explanation
Fig. 1 is that the present invention is applied to the structural representation on power shovel.
Mark in figure: 1 is the scraper bowl main body, and 2 is wearing plate.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment: a kind of wearing plate, its composition quality per-cent is respectively: the ratio of C is 0.21%-0.25%, and the ratio of Mn is 1.50%-1.80%, and the ratio that the ratio of P is≤0.02%, S is≤0.015%, and all the other are Fe.
As shown in Figure 1, wearing plate involved in the present invention 2 welding is covered to scraper bowl main body 1 outside surface, as to a kind of application of the present invention.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. a wearing plate, be characterised in that its composition quality per-cent is respectively: the ratio of C is 0.21%-0.25%, and the ratio of Mn is 1.50%-1.80%, and the ratio that the ratio of P is≤0.02%, S is≤0.015%, and all the other are Fe.
2. a power shovel, is characterized in that: wearing plate welding claimed in claim 1 is covered to scraper bowl main body outside surface.
