Abstract

The invention discloses a system for simultaneous non-contact measurement of the element content and the temperature of molten metal. The system comprises a non-contact light guide system. A pulse laser is arranged above the non-contact light guide system. The non-contact light guide system is provided with a signal light splitting light path and a focal-point-adjustable telescope in sequence from top to bottom in the laser incidence direction, and lenses are arranged at the tail end of the signal light splitting light path and connected with spectrographs through optical fiber feed-in flanges and optical fibers. The pulse laser and the spectrographs are connected with a sequential control system and a computer system. A gate valve and a standard flange connector are arranged on the lower portion of the non-contact light guide system. An auxiliary vacuum system is connected to the side wall of the non-contact light guide system. Element content detection and temperature measurement are organically combined, so that the structure is compact. Meanwhile, the light guide system can adjust the focal point automatically, so that the detection space range and waveband range are wide. The system is suitable for smelting furnace bodies and other occasions needing online content detection and high-temperature measurement.

Description

technical field [0001] The invention relates to a spectrum detection technology, in particular to a system for non-contact measurement of the element content and temperature of molten metal at the same time.
