Problems solved by technology

[0002] At present, the nozzle water flow density test uses a water collector. After the water is collected, the water collecting test tube is taken out and the data is read manually. The work intensity is high and the accuracy is low.
There are also sensors installed in the water collector to collect data, but the cost of installing sensors throughout the spray range is too high

Embodiment Construction

[0017] As shown in Figure 1, it includes a nozzle moving mechanism, a nozzle 3, a signal conditioner 10, a computer data acquisition and analysis unit 11, a water collector 8 and a sensor moving mechanism, and the water collector 8 is fixed on the sensor moving mechanism. The sensor moving mechanism drives the water collector 8 to move to the detection position; the nozzle 3 is fixed on the nozzle moving mechanism, the nozzle 3 is downward, and the nozzle 3 is moved to the top of the water collector 8 through the nozzle moving mechanism, and the bottom of the water collector 8 is installed with liquid The position sensor 7 is driven by the stepper motor 6 to drive the transmission belt 16 and the screw nut 14 to control the water flow density and the water collection unit to move within the spray range of the entire nozzle 3 . When measuring, first move the water collector 8 to the test position, open the cover of the water collector 8, and start collecting water. After a certa...

Abstract

The invention belongs to the field of metallurgy equipments, and relates to a water flow density measuring system for a two-cooling nozzle of a slab caster. The invention is characterized in that the invention at least comprises a nozzle moving mechanism, a nozzle (3), a signal conditioning device (10), a data collecting and analyzing unit (11) of a computer, a water collector (8), and a sensing moving mechanism. The water collector (8) is fixed on the sensing moving mechanism and driven (8) to a checking position through the sensing moving mechanism, the nozzle (3) is fixed downwards on the nozzle moving mechanism and driven to the upper portion of the water collector (8) through the nozzle moving mechanism, water is sprayed by the nozzle (3), spraying densities of different spaces are given by a liquid level sensor (7) inside the water collector (8), a signal is used to output data to the data collecting and analyzing unit (11) of a computer after being amplified through the signal conditioning device (10) and gives a three-dimensional water spraying density inundation distributing map. The invention has precise measurement, short measuring time, and low measuring cost.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment and relates to a water flow density measurement system for a secondary cooling nozzle of a slab continuous casting machine. Background technique [0002] At present, the nozzle water flow density test uses a water collector. After the water collection is completed, the water collection test tube is taken out and the data is read manually. The work intensity is high and the accuracy is low. There are also sensors installed in the water collector to collect data, but the cost of installing sensors throughout the spray range is too high. Contents of the invention [0003] The purpose of the present invention is to provide a secondary cooling nozzle water flow density measurement system of a slab continuous casting machine, which is used for accurate secondary cooling nozzle water flow density and reduces measurement cost. [0004] The object of the present invention is achieved in this way, ...
