Problems solved by technology

[0004] The first generation is wear-resistant steel surfacing, and the service life is very short;
[0005] The second generation is the welded body of ordinary cemented carbide and steel substrate. The disadvantage is that the thermal expansion coefficient of ordinary cemented carbide is greatly different from that of the substrate steel. During welding, the internal stress will cause huge de

Description

Technical field [0001] The invention relates to the field of preparation of new materials, in particular to a new material for glasses plates and cutting rings for concrete delivery pump trucks and a preparation method thereof. Background technique [0002] Concrete pump, also known as concrete pump, is composed of pump body and conveying pipe. It is a machine that uses pressure to continuously transport concrete along pipelines. It is mainly used in housing construction, bridge and tunnel construction. At present, it is mainly divided into gate valve concrete pump and S valve concrete pump. Another is to install the pump body on the chassis of the car, and then equip it with a retractable or flexural placing boom to form a pump truck. [0003] The glasses plate and cutting ring are the core parts, and their wear resistance and reliability are directly related to the efficiency of concrete construction. The glasses plate and cutting ring materials have undergone several generati...
