Title:
溶融した塊の冷却曲線を測定するための方法及び装置
Document Type and Number:
Japanese Patent JP2009513934
Kind Code:
A
Abstract:
A device is provided for measuring the cooling curve of melts and/or the heating curve of melt samples with an optical fiber, wherein an immersion end of the optical fiber having an at least partially free surface is surrounded with a spacing by a temperature-resistant sample-receiving chamber. The optical fiber is immersed with its immersion end in the melt, and a sample is thereby formed in the sample-receiving chamber. The sample-receiving chamber with the sample and the optical fiber are thereafter pulled out of the molten metal. The cooling curve of the sample and/or, after previous solidification of the sample, the temperature profile during heating is measured with reference to a signal obtained by the optical fiber and forwarded to a measurement device.
