Title:
MOLTEN METAL TEMPERATURE MEASURING INSTRUMENT AND METHOD
Document Type and Number:
WIPO Patent Application WO/2003/010501
Kind Code:
A1
Abstract:
A cooling system for protecting image fiber and an image pickup apparatus from thermal effect, and a molten metal temperature measuring instrument capable of easily controlling the cooling system, and consistently measuring the temperature. The molten metal temperature measuring instrument comprises four connectable parts including a nozzle part, a purge and cooling gas introduction unit, an image fiber fitting part having a window glass, and an image fiber protective tube, and receives much heat radiation by reducing the distance between the nozzle tip as a heat radiation introduction unit for a double−pipe nozzle and a light receiving unit at hr end of the image fiber.
