Automatic positioning and escaping system for molten metal liquid level sensor

Abstract

The invention provides an automatic positioning and escaping system for a molten metal liquid level sensor. The automatic positioning and escaping system comprises a system body, a base, a sensor cooling air interface, a pneumatic pressure adjusting and indicating unit, a heavy-load pneumoelectric hybrid cable quick interface, an MCU main controller, a manual winding and unwinding operation buttonand the like. The invention provides an automatic positioning and escaping system for a molten metal liquid level sensor. The automatic positioning and escaping system is a complete and independent system. Sensor work positioning can be independently undertaken and an escape task can be triggered and executed; field compressed air is taken as power, embedded CPU control is used as a core. The system has the beneficial effects of compact and reliable structure, high positioning precision, rapid sensor protection and personnel safety protection, can be suitable for any occasion with molten metal liquid level detection control, is ultrathin and compact in structure, and can meet the installation requirement of a limited space between the upper part of any continuous casting crystallizer andthe lower part of a tundish.

Description

technical field [0001] The invention relates to the field of molten metal liquid level detection, in particular to an automatic positioning and escape system for a molten metal liquid level sensor. Background technique [0002] In the field of molten metal level detection, almost all the focus is currently on two types of technologies: isotope and eddy current. The isotope technology has a wide range of applications and is easy to install and use. However, due to the fluctuation statistical characteristics of nuclear radiation ionization, the detection accuracy of liquid level is limited, resulting in limited quality of end products. Secondly, nuclear radiation affects the surrounding environment and human body. The scope of application of the eddy current technology and the convenience of installation and use are not as good as isotope detection, but it has the advantage of convenience. In the field of molten metal liquid level detection, the most basic mode of domestic ap...
