The system of installation is intended for automatic nondestructive testing of
mechanical properties of low-carbon steel by a thickness from 0.15mm up to 12 mm
moving in technological line with a speed from 0.1 up to 5m/s. Testing as of
continuous band of metal, and separately following one after another sheet is
possible. Testing a series of medium-low-carbon cold rolled and series of hot
rolled steel is possible. The advantage of this system make possible to evaluate
surface damage and bulk property of steel continuously and simultaneously.
The testing is carried out by way of periodic local magnetization of moving
rolled produce from both sides with a consequent measurement of gradients of
normal component of residual magnetization field strength on both sides of a
sheet and their average. The dependence between the installation indication and
the tested properties the consumer determines as the correlation between them.
The installation consists from two transducers, the generator and the electronic
block. The opportunity of connecting the ammeter and the PC exists.
This installation has a metrological supervision.
