High-strength wear-resistant nodular cast iron

Abstract

The invention discloses high-strength wear-resistant nodular cast iron. The high-strength wear-resistant nodular cast iron comprises an iron plate, wherein linear grooves are formed in the upper end face and the lower end face of the iron plate; V-shaped clamping plates are arranged in the linear grooves, and V-shaped openings of the V-shaped clamping plates are fixedly connected to ports of the linear grooves; meanwhile the intersection ends of the V-shaped clamping plates are fixedly connected into the inner walls of the linear grooves; and grooves are formed in the upper end face and the lower end face of the iron plate. The V-shaped openings of the V-shaped clamping plates are fixedly welded to the ports of the linear grooves formed in the end faces of the iron plates, and meanwhile the intersection ends of the V-shaped clamping plates are fixedly connected into the inner walls of the linear grooves, so that the strength at the positions of the linear grooves is enhanced, and the situation that the strength is reduced due to the fact that the iron plate is thinned due to the formation of the linear grooves is avoided; and through holes are formed in the intersection ends of the V-shaped clamping plates, and plate materials of the iron plate on the upper sides and the lower sides of the intersection sections of the V-shaped clamping plates are connected in a way that extending bodies penetrate through the through holes, so that the situation that the V-shaped clamping plates block connection of the plate materials of the iron plate on the upper sides and the lower sides of the intersection ends of the V-shaped clamping plates, and the strength of the iron plates is affected is avoided.

Description

technical field

[0001] The invention relates to the technical field of nodular cast iron, in particular to a high-strength and wear-resistant nodular cast iron. Background technique

[0002] Ductile cast iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance that it has been successfully used to cast some complex stress, strength, toughness, and wear resistance. Parts with high performance requirements;

[0003] The disadvantage of the iron parts of general ductile iron is that the iron plate made of general ductile iron will have some strip grooves on its end surface due to the needs of use, which will cause the thickness of the position to become thinner, which will Reduce the strength here, and the end face of the iron plate made of ductile iron will still wear when it is rubbed. Although it is wear-resistant, it will show wear and tear after a long time. Conte...
