A computerised Rogowski-Chattock Potentiometer (RCP) compensated on-line power-loss measuring system for use on grain-oriented electrical steel production lines

The magnetostriction and magnetic properties of electrical steel are depended on the external stress. In this paper, a noncontact magneostriction measuring system using laser displacement meter with high resolution of 10 nm has been built. The grain-oriented electrical steel with dimensions 500 mm × 100 mm × 0.3 mm was measured between 20 MPa and-20 MPa. The magnetostriction and magnetic properties were highly sensitively to stress. A clear relationship between power loss and magnetostriction under stress was found, and the underlying mechanism has been discussed.

In order to measure the rotating machinery fault quickly and conveniently at a construction site, a new measuring system of rotating accuracy of spindle was developed according to three point method. With summarizing the principle of error separation technique based on three point method, the function, hardware construction and software module of this module were introduced. The problem of harmonic suppression is relieved by changing the sensor arrangement. The measuring system mainly consists of three eddy current sensors ,a acquisition card and a personal computer. After a few parameters were inputted, the rotation accuracy of calculation and display could be carried out automatically on line at a construction site.

Quenching And Tempering

Pre-hardening plastic die steel can be directly processed into the mold, and it doesnt need quenching and tempering again, which avoids quenching deformation and ensures the size precision of the mold. On-line quenching of die steel can shorten the production cycle, and it has the advantage of energy saving. In the paper, a new on-line quenching device was introduced, and the temperature field calculation model of 3Cr2NiMo die steel was established. The cooling technology of three typical thickness steel plates was studied. The results provided the theoretical basis for die steel production.
