Concrete pump pipe inner wall hardening by supersonic frequency induction hardening equipment

Concrete pump pipe, the abbreviation of concrete delivery pump pipe, is often called concrete pump pipe because concrete is referred to as concrete. It is easy to understand that the pump pipe is a new type of construction engineering accessory product that appeared simultaneously with the appearance of the concrete delivery pump. Its appearance has greatly improved the efficiency of construction construction. The one-bucket operation method has been changed to quickly transport the concrete to the place where it needs to be poured, which has increased the construction efficiency by nearly a hundred times. It can be seen from its working environment that the inner wall of the concrete pump pipe needs to bear a huge friction force during the working process. Therefore, the inner wall of the concrete pump pipe needs to be quenched and heat treated. For this reason, we have specially developed a special quenching equipment for the inner wall of the concrete pump pipe - supersonic frequency induction hardening equipment.

The inner wall of the concrete pump pipe is quenched and heat-treated by supersonic frequency induction quenching equipment. After quenching, the hardness reaches HRC52-60, the depth of the hardened layer is 1.5-2.5mm, the travel speed is 300-400mm/min, and the 3-meter concrete pump takes about 10 minutes. The service life of the concrete pump pipe is increased by 3-5 times after quenching, and there is almost no deformation after quenching. It is not accidental that the concrete pump pipe adopts supersonic frequency induction quenching equipment for quenching heat treatment, but it is determined by its unique advantages. Supersonic frequency induction hardening equipment is produced by advanced IGBT modules, which has the advantages of simple operation, fast heating speed, no oxidation layer in quenching, energy saving and environmental protection.
