Abstract

The invention belongs to the metallurgical equipment field, which relates to a testing system for an impact force of a secondary cooling nozzle of a slab caster. The invention is characterized in that a waterproof strain type micro force value sensor (8) is fixed on a sensing shift mechanism, the waterproof strain type micro force value sensor (8) is driven to shift to a testing position through the sensing shift mechanism, a nozzle is fixed on a nozzle shifting mechanism, a nozzle (3) is arranged downwards, the nozzle (3) is shifted to the upper portion of the waterproof strain type micro force value sensor (8) through the nozzle (3) shifting mechanism, the nozzle (3) sprays water, the waterproof strain type micro force value sensor (8) is driven to shift through the sensing shift mechanism, a strain type electric signal is produced by a spraying percussive force in different space which is given by the waterproof strain type micro force value sensor (8), the signal is amplified through a signal conditioner 10, a data which is output by the signal conditioner 10 is transmitted to a data collecting and analyzing unit (11) of a computer, and an inundation distributing graph of three-dimensional water spraying percussive force is given. The invention can accurately measure the percussive force characteristics of a nozzle, which improves measuring accuracy, and reduces measuring cost.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment and relates to a system for measuring the impact force of a secondary cooling nozzle of a slab continuous casting machine. Background technique [0002] At present, the nozzle impact force test is performed manually in China, such as fixing the stress sensor at the place where the impact force of the nozzle needs to be measured, and collecting the data of the stress sensor. After the measurement of this point is completed, manually adjust the position of the stress sensor, and repeat the above measurement at other places of the impact force of the nozzle. Due to the limited effective measurement area of ​​nozzle impact, it is not possible to arrange a large number of precision stress sensors. This makes the test accuracy of single-point movement or a small number of point measurements poor, and the measurement cost increases and the time period is long.
