IPC: G01N27/72
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a method in which the plasticization of a steel material can be determined nondestructively and directly by a method wherein a magnetic sensor is scanned along the steel material in which a magnetic field is generated by a magnet and a charge in the magnetic field caused by magnetic anisotropy induced by the plastic deformation of the steel material is detected. SOLUTION: Both poles of an electromagnet are brought into contact with the surface of a steel material 1, the steel material is magnetized, and one or a plurality of parts 8, 9 which are magnetized to be striped patterns are formed. Spontaneous magnetic fields are generated in the magnetized parts 8, 9 in outer parts from the surface of the steel material 1. When a magnetic sensor 10 is scanned in a noncontact manner along the surface of the steel material 1 in a crossed direction, a change in the spontaneous magnetic fields from the steel material 1 can be measured by a detecting coil at the magnetic sensor 10. That is to say, the amplitude of the spontaneous magnetic fields in the magnetized parts 8, 9 in an initial state before a load is applied to the steel material 1, but is becomes small as a plastic deformation progresses.  Consequently, the maximum value (or the minimum value) of the amplitude of the spontaneous magnetic fields in the upper part and the lower part of the magnetized parts 8, 9 is measured, and a plastic strain can be detected.

Title: Prevention method of center segregation in continuous casting
Inventor: IMAI FUMIO
IPC: B22D11/16
Filed: 1978-11-30
Abstract: PURPOSE: To rapidly perform center segregation preventive measure by estimating the center segration of the slab being made under dynamic roll gaps and operating conditions during casting and obtaining a cause roll from the result of said estimation.  
     CONSTITUTION: A roll gap continuously changes owing to the change in thermal load, mechanical load or the rolls per se during continuous casting and the solidification condition of the slab relatively changes with the changes in operating conditions. When the suction of thickened molten steel occurs at the leading end of the  unfrozen part in correspondence to this and a center segragation defect is produced because of this, the following processings are performed. Namely, the dynamic roll gap during casting is measured and solidified shell thickness is calculated from the rates of slab cooling, casting speeds, molten steel temperature, steel kind components, etc. Based on these factor groups, the estimation of the presence or not of the production of the center segregation is on-line-accomplished and based on this, the cause roll for the same is obtained. Further based on this result, the center segregation preventive measure such as casting speed decrease is on-line fed back rapidly in an optimum manner.
