Embodiment Construction
[0055] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings of the embodiments.
[0056] The structure of the online measuring device for the sliding nozzle opening of the continuous casting ladle of the present invention can be found in figure 1 .
[0057] First explain the concept of the sliding nozzle of the continuous casting ladle: Figure 1-Figure 3 As shown, the molten steel flows from the ladle 1 into the tundish 3 first, and then the tundish 3 distributes the molten steel to each crystallizer (not shown). Nearby and the sliding nozzle 2 that communicates with ladle water outlet 11 controls the flow of molten steel, and the size of sliding nozzle 2 opening degree has determined the flow size that flows into tundish 3 molten steels.
[0058] Such as figure 1 As shown, the continuous casting ladle sliding nozzle opening online measuring device of the present invention comprises:

The invention provides an online measuring device and method for the opening degree of a sliding nozzle of a continuous casting ladle. The problem that an existing measuring device is easy to damage is solved. The device comprises pressure sensors, a signal processing unit, a technological signal interface unit and a calculation controller, wherein the pressure sensors are mounted on a steel ladle rotatable table and are used for measuring current signals of the total weight of the steel ladle at present, and the signal processing unit is connected with the pressure sensors and processes the current signals into the total weight value of the steel ladle; the technological signal interface unit converts signals of currently-poured steel types into steel type codes, and then the steel type codes and the net weight of the currently-poured steel ladle are output through the technological signal interface unit together; the calculation controller is connected with the signal processing unit and the technological signal interface unit and reads out the total weight value of the steel ladle, the signals of the steel type codes and the signals of the net weight of the steel ladle at present; and through calculation, the size of the opening degree of the sliding nozzle is obtained. According to the device, the gradient and the rate of the change tendency of the weight of molten steel in the steel ladle are measured, and parameters such as static pressure and viscosity of molten steel at a molten steel outlet are combined, so that the opening degree value of the sliding nozzle can be obtained through calculation; and the device is not easily damaged, and it is ensured that the continuous casting pouring process is smoothly carried out.
Description
technical field [0001] The invention relates to a measurement technology for the opening of a ladle nozzle, in particular to an online measuring device and a measuring method for the opening of a sliding nozzle of a continuous casting ladle. Background technique [0002] In continuous casting production, the molten steel flows from the ladle into the tundish, and then the molten steel is distributed to each mold by the tundish, and then it is solidified and crystallized by the mold and cast into a slab. Among them, during the process of molten steel flowing from the ladle into the tundish, the flow of molten steel is controlled by a sliding nozzle installed near the outlet of the ladle, and the opening of the nozzle determines the amount of molten steel flowing into the tundish. In order to accurately control the size of the flow, it is necessary to measure the size of the opening of the sliding nozzle. For example, in the continuous casting steel pouring optimization contr...
