Title: Eddy current flaw detecting method of tube or the like
Inventor: TAKAHASHI AKIRA
IPC: G01N27/90
Filed: 1983-12-24
Abstract: PURPOSE:To evaluate a defect of a tube speedily by inspecting the tube with an eddy current flaw detection probe and calculating the relation between a phase angle and a thickness reduction rate, and comparing it with inspection data on a tube which is worked into a standard defective previosuly. CONSTITUTION:The defect of the tube 20 is inspected with, for example, an air gun type pusher puller 10. The eddy current flaw detection probe 18 incorporating an exciting coil 24 and a detection coil 26 is inserted into and drawn out of the tube 20 with a trigger. Signals of the phase angle and thickness reduction rate corresponding to the defect are inputted from the probe 18 to a separating circuit 28 and a microcomputer 34. Then, the relation between the phase angle and thickness reduction rate as to the tube in which the standard defect is worked previously is inputted to the microcomputer 34. Then, the phase angle and thickness reduction rate as to the objective tube 20 are measured and their signals are inputted to the microcomputer 34 and compared with the signals of the standard defect to detect the defect of the tube 20. Therefore, even when inspection conditions change, the relation between the phase angle and thickness reduction rate on the conditions is calculated and the inspection result is evaluated speedily.

Abstract: PURPOSE:To prevent the development of longitudinal crack on a continuous cast slab by setting molten steel temp., shape of nozzle for pouring molten steel and casting velocity to the specific conditions and controlling shell washing ratio to the specific value or less at the time of continuously casting the steel slab at a high speed of the specific value or more. CONSTITUTION:At the time of continuously casting the molten steel, in the case of continuously casting at a high velocity, e.g. >=4m/min the casting velocity, the shell washing in the mold is developed with discharging flow of the molten steel poured into the mold and with this cause, uneven thickness of the shell in the width direction of the mold is developed and the longitudinal crack on the continuous cast slab is developed. This shell washing ratio phiat the time of continuous casting is shown in the equation I with functions of the casting velocity V, cross sectional film ratio S of the mold to discharging hole in the nozzle for pouring the molten steel and overheat temp.  T and also since this is decided with the shell thickness of the mold as shown in the equation II, by adjusting either V or S in the equation I to make phi value <=0.1, the development of longitudinal crack to the continuous cast slab at the time of continuously casting at a high velocity is prevented.
