摘要：The system developed for the continuous temperature measurement ofmolten metal (1), like in the case of the continuous casting machine tundish (2), uses anoptical process to control the continuous casting machine speed, and it consists of anoptical infra-red sensor (8) protected by a cooled jacket (30). This two-color sensor (8),fitted with optical fiber (9) and an optical signal converter (10), is focused inside a highthermal and light conductivity ceramic tube (15), and it enables accurate temperaturereadings of molten steel (1) in the tundish (2). This practical device avoids theinconvenience of the method currently being used. It reduces the operator's hightemperature exposure time, lowers maintenance downtime, minimizes the operatingrisks, improves safety and enables fast, simple replacement, resulting in improved slabquality and, as a consequence, lower costs.
