Description
Technical Field
The utility model relates to a ball mill technical field, concretely relates to high rigidity ausferrite welt structure.
Background
The ball mill is one of highly fine grinding machines widely used in industrial production. In the ball mill, the lining plate is used for protecting the cylinder body, so that the cylinder body is prevented from being directly impacted and abraded by the grinding body and materials, and meanwhile, the lining plates in different forms can be used for adjusting the motion state of the grinding body, so that the grinding effect of the grinding body on the materials is enhanced, the grinding efficiency of the mill is improved, and the yield is increased. At present, the wear resistance of cast iron lining plates used by domestic ball mills is poor, and the cast iron lining plates are easy to break, so that the problem needs to be solved urgently.
SUMMERY OF THE UTILITY MODEL
Based on the technical problem that the background art exists, the utility model provides a high rigidity ausferrite welt structure.
The utility model provides a high rigidity ausferrite welt structure, include: the lining plate components comprise base plates and trapezoid lifting strips arranged on the base plates;
the base plate comprises a base layer and a wear-resistant layer, the base layer is made of low-carbon steel materials, the wear-resistant layer and the trapezoidal lifting strips are made of austenitic materials, and the trapezoidal lifting strips are integrally formed on the wear-resistant layer.
Preferably, the cross-section of trapezoidal lifting strip is isosceles trapezoid, and the contained angle that isosceles trapezoid's waist and the limit of keeping away from the wearing layer formed is the fillet.
Preferably, the radius of the rounded corner is 1/4 the length of the top surface.
Preferably, one or more transition layers are arranged between the base layer and the wear-resistant layer, the transition layers are made of carbon steel materials or alloy steel materials, and the hardness of the transition layers is gradually reduced from the wear-resistant layer to the base layer.
Compared with the prior art, the utility model discloses following beneficial effect has:
(1) thereby form complete base plate through basic unit and the wearing layer that uses different metal material to make for the different positions of base plate possess different performance, thereby improved the wear resistance of this welt structure, and avoided fracture or wear-through, compare with high chromium steel moreover, the ausferrite body has similar hardness, lower density and lower cost, consequently, the base plate of constituteing by basic unit and wearing layer greatly improves the life of this welt structure, and has reduced manufacturing cost simultaneously.
(2) Because trapezoidal lifting strip with wearing layer integrated into one piece has higher hardness, trapezoidal lifting strip has better promotion effect to the grinding body, can prolong the life of this welt structure when improving grinding effect.
(3) The lining plate structure formed by the plurality of lining plate components can reduce the maintenance and production cost.
To sum up, the utility model provides a high rigidity ausferrite welt structure has higher wearability and impact resistance, and is with low costs, longe-lived.

Detailed Description
Referring to fig. 1, the utility model provides a high rigidity ausferrite welt structure, include: the lining plate components comprise a base plate and a trapezoidal lifting strip 3 arranged on the base plate;
the base plate includes basic unit 1 and wearing layer 2, and basic unit 1 adopts low carbon steel material to make, and wearing layer 2 and trapezoidal lifting strip 3 adopt the ausferrite body material to make, and trapezoidal lifting strip 3 integrated into one piece is on wearing layer 2.
In the utility model, the maintenance and production cost can be reduced by arranging the lining plate structure consisting of a plurality of lining plate components; the base layer 1 and the wear-resistant layer 2 made of different metal materials are used to form a complete base plate, so that different parts of the base plate have different performances, the wear resistance of the lining plate structure is improved, fracture or abrasion is avoided, and compared with high-chromium steel, the austenitic body has similar hardness, lower density and lower cost, so that the base plate consisting of the base layer 1 and the wear-resistant layer 2 achieves the purpose of prolonging the service life and simultaneously reduces the production cost; and trapezoidal lifting strip 3 with wearing layer 2 integrated into one piece has higher hardness, and trapezoidal lifting strip 3 has better promotion effect to the grinding body, can prolong the life of this welt structure when improving the grinding effect of grinding body.
To sum up, the utility model provides a high rigidity ausferrite welt structure has higher wearability and impact resistance, and is with low costs, longe-lived.
In order to alleviate the stress concentration phenomenon in the grinding process, reduce trapezoidal lifting strip 3's wearing and tearing volume to prolong the life of this welt structure, in this embodiment, trapezoidal lifting strip 3's cross-section is isosceles trapezoid, and isosceles trapezoid's waist is the fillet with the contained angle that keeps away from wearing layer 2's limit formation.
In order to better reduce the stress concentration during the grinding process by considering the lifting action of the trapezoidal lifting strip 3 on the grinding body, the radius of the fillet is 1/4 of the length of the top surface in the embodiment.
In order to better absorb the collision of the grinding body to this trapezoidal lifting strip 3 and base plate, reduce the risk of this welt structure damage to the life of extension this welt structure, in this embodiment, be equipped with one or more transition layers between basic unit 1 and the wearing layer 2, the transition layer adopts carbon steel material or alloy steel material to make, and the hardness of transition layer is reduced gradually to the direction of basic unit 1 by wearing layer 2.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
