Abstract

The invention relates to a double-swing angle roller gap measuring device for a metallurgical casting machine, belongs to the field of metallurgy, and aims to solve the problem that the conventional swing angle roller gap instrument cannot normally work in a severe environment with violent temperature variation, high electromagnetic interference and cooling water injection. The device is arrangedon the tail section of a dummy ingot cable body of the metallurgical casting machine and comprises a contact swing mechanism and a measuring mechanism, wherein the measuring mechanism comprises an upper measuring swing arm, a lower measuring swing arm, a spring, a displacement sensor and a measuring module; the spring and the displacement sensor are positioned between the upper measuring swing arm and the lower measuring swing arm; the contact swing mechanism comprises an upper contact block arranged on the upper measuring swing arm and a lower contact block arranged on the lower measuring swing arm; the distance between the rotation center of the upper measuring swing arm and the upper edge of the dummy ingot cable body is equal to the distance between the rotation center of the lower measuring swing arm and the lower edge of the dummy ingot cable body, and the height of the dummy ingot cable body is greater than the double distances; and the upper measuring swing arm and the lower measuring swing arm have different rotation centers and the same rotation radius.

Description

technical field [0001] The invention relates to a double-swing angle roll gap measuring device for a metallurgical casting machine, which belongs to the field of metallurgy. Background technique [0002] Continuous casting machine technology and equipment maintenance personnel can identify problem areas of continuous casting machine equipment by analyzing the measurement results. If these problems are not discovered and solved in time, the quality of continuous casting billets will be degraded, steel breakouts in the casting process, and surface defects will occur. And problems such as internal cracks and centerline segregation. [0003] At present, there are mainly two types of devices for measuring the roll gap of casting machines: contact type and non-contact type. Since non-contact measurement is greatly affected by the environment at the casting machine work site, temperature, electromagnetic interference, cleaning links, dust impurities, etc. The impact of non-contact...
