Method and apparatus for testing spraying characteristic of secondary cooling nozzle of continuous casting

Abstract

The invention discloses a spray character test method and device of continuous casting two-cold-sprayer, which comprise the following steps: 1. the moving sprayer sprays water through the water-spray quality sensor and water-spray bunch pressure sensor on the downward moving gathering point; 2. the water-spray quality sensor and water-spray bunch pressure sensor transmits the real-time gathered spray quantity and increment and spray bunch pressure value to the computer; 3. the computer calculates the flow density value and bunch pressure value according to the setting parameter and program, which generates the distribution graph of spray flow density and bunch pressure. The entire course can be controlled by computer automatically, which improves the automatic degree greatly to finish the test by one person. The test result can be printed at the report pattern, which displays the distribution graph of spray flow density and bunch pressure.

Description

technical field [0001] The invention relates to a performance detection method and a detection device of a continuous casting secondary cooling nozzle, which is suitable for detecting the water flow density distribution and impact pressure distribution characteristics of the air-water nozzle spray of the continuous casting secondary cooling nozzle. Background technique [0002] The continuous steel casting process is the cooling and solidification process of molten steel. It is a heat transfer process that takes away the superheat, solidification latent heat and waste heat of liquid steel in a suitable way to solidify molten steel into solid steel; The main measure is to take the above three kinds of heat away through external water cooling. In the cooling and solidification process of the continuous casting slab, the cooling and solidification in the secondary cooling zone is the central link of the slab solidification. Among the various heat transfer methods in the second...

Problems solved by technology

The disadvantage of this test method is that there are many sensors, large investment, high maintenance work and maintenance costs, and there are also problems that data accuracy and comparability are affected due to errors between the sensors themselves.

[0005] In addition, the existing nozzle water flow density distribution and impact pressure distribution tests are all carried out on two different sets of devices. Whether the determination of the two detection parameters can be completed on the same device and at the same time overcome the shortcomings of the existing detection methods is an important issue of the present invention.
