THE PULSE MAGNETIC ON-LINE CONTROLLER IMPOK-1B


PURPOSE

      The installation IMPOK-1B is intended for automatic nondestructive testing of mechanical properties of low-carbon steels by a thickness from 0,15 mm up to 12 mm moving in technological line with a speed from 0,1 up to 5 m/s. Testing as of continuous band of metal, and separately following one after another sheets is possible.
      Testing a series of medium- and low-carbon cold rolled and series of hot rolled steels is possible.

OPERATION PRINCIPLE

      The testing is carried out by way of periodic local magnetization of moving rolled products from both sides with a subsequent 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.


CONSTRUCTION

      The installation consists from two transducers, the generator and the electronic unit. The opportunity of connecting the ammeter and the PC exists.
