PERFORATIONS ON THE SURFACE OF IRON CASTINGS

Литьë и металлургия, 2018
The mechanism of the formation of veinings on cast iron castings whose cores are made of a cold-hardening mixture is studied. It is shown that the cause of the formation of the veinings are the stresses in the surface layer of the core that arise when a ...

Precision planter monitoring system based on mobile communication network

IET Networks, EarlyView., 2022
Abstract Sowing is an important link in agricultural production and the basis for ensuring high yields and bumper harvests. Agriculture requires precision plows with good performance and stable work. However, the seeding process is in a completely closed state, and the operator relies mainly on experience to judge the operating state and performance of
