Method for detecting impact capability of steel high pressure water jet rust remover

The invention relates to a method for detecting the impact capability of a water spray rust remover, in particular to a method for detecting the impact capability of a steel high pressure water spray rust remover.

Referring to Figure 1, there is shown a schematic view of the configuration of a conventional steelworks. As shown in Fig. 1, the conventional steelworks are equipped with two sets of high pressure water spray rust removers 51, 52. One set of high-pressure water spray rust remover 51 is disposed in front of the opener 60 to remove the scale generated by the heating furnace to avoid rolling in the opening process. Another set of high-pressure water spray rust remover 52 is disposed in front of the roughing mill 70 to remove the scale produced by the rough rolling reciprocating rolling process to prevent the scale from rolling in the reciprocating rolling process during the rough rolling process. Defects are formed by rolling in a scale and rolling into a secondary scale.

The rust removal capability of the high-pressure water spray rust remover is usually obtained by detecting the impact capability of the high-pressure water spray rust remover, and the conventional method for detecting the impact capability of the high-pressure water spray rust remover is to use the surface paint before the opening of the embryo. The test embryo is subjected to a spray test, and the impact capability of the high pressure water spray rust remover is evaluated based on the pattern in which the paint is sprayed. However, the biggest disadvantage of the above method is that the entire test process cannot be standardized. For example, the spray time varies with the paint layer variation. If the spray pattern is not obvious, the spray time will increase. The general experience value is 90~180s. Although the final pattern can be obtained obviously, the ejection time is much longer than the normal steel steel embryo production passage time, and the actual impact capacity of the high-pressure water spray rust remover cannot be reflected, and the nozzle of the high-pressure water spray rust remover cannot be accurately judged. The true state of affairs.

Therefore, it is necessary to provide an innovative and progressive steel high pressure water spray rust remover Impact capability detection method to solve the above problems.

The invention provides a method for detecting impact capability of a steel high-pressure water spray rust remover, the method comprising the following steps: (a) providing a steel test spray plate having a detection section; (b) installing at least one test The aluminum plate is in the detection section of the steel test strip; (c) the steel test strip mounted with the at least one test aluminum plate is fed into a high pressure water spray rust remover, and the plurality of high pressure water spray rust removers are The nozzle performs a high pressure water spray test on the at least one test aluminum plate to form a rust removal pattern on the surface of the at least one test aluminum plate; (d) exiting the steel test strip and removing the at least one test aluminum plate; and (e) And analyzing the rust removal pattern of the at least one surface of the aluminum plate to evaluate the impact capability of the high pressure water spray rust remover.

The rust removing pattern of the at least one detecting aluminum plate surface of the present invention can reflect the actual impact capability of the high pressure water spray rust remover, and can accurately determine the true condition of the nozzles of the high pressure water spray rust remover.
