Recently, a good news came from the construction site of the Hepu River Bridge Reconstruction Project on the 209 line of the provincial road in Ganxi Province and the construction base of the Lanzhou Metro Line 2, and the new rotary shovel developed by the Yellow River Cyclone Company was successfully tested on site!
Rotary tooth is a construction machine that is used for hole forming in building foundation engineering. It is widely used in various foundation construction such as cast-in-place pile, continuous wall and foundation reinforcement. The research team of the Super-hard Composites Division has successfully developed a new type of rotary-cutting teeth for cobblestone formations in combination with the current large-scale project construction at home and abroad. The newly developed rotary cutter uses a new wear-resistant material to protect the tooth body. Its wear resistance is higher than that of ordinary wear-resistant electrode and plasma wear-resistant solder layer. The wear layer hardness can reach 62 or more. Rapidly improve the construction schedule, and also greatly reduce production costs.
Ganxi County, Gansu Province is adjacent to the Weihe River, and Lanzhou City is adjacent to the Yellow River. The stratum is mainly cobblestone and sandstone. This stratum has high requirements on the wear resistance of the tooth body. At the construction site, the management engineer Baigong greatly praised the rotary shovel of the Yellow River Cyclone Company. He said: "After a week of on-site trials, the service life of the new rotary burrs exceeds the rotary boring teeth we use now at least 1.5 times. !"
After the successful trial of the product, the Yellow River whirlwind will concentrate on the products to make the products better, and let the new rotary burrs help the construction of subways and bridges in China, and play their unique role in the pile foundation of special rock layers.

Inconel alloys are oxidation- and corrosion-resistant materials well suited for service in extreme environments subjected to high pressure and kinetic energy. When heated, Inconel forms a thick and stable passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high-temperature applications where aluminium and steel would succumb to creep as a result of thermally induced crystal vacancies (see Arrhenius equation). Inconel's high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy. In age-hardening or precipitation-strengthening varieties, small amounts of niobium combine with nickel to form the intermetallic compound Ni3Nb or gamma prime (γ'). Gamma prime forms small cubic crystals that inhibit slip and creep effectively at elevated temperatures.The formation of gamma-prime crystals increases over time, especially after three hours of a heat exposure of 850 °C, and continues to grow after 72 hours of exposure.
