[0002] In the process of continuous casting steel production, the crystallizer water flow detection is the most core link in metallurgical continuous casting system, and the crystallizer water flow detection signal error will cause accident stop pouring, and even may lead to leakage accident in the process of pouring.

[0020] In addition, the terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh" and "eighth" are only used for descriptive purpose and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second", "third", "fourth", "fifth", "sixth", "seventh" and "eighth" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise specifically limited.

[0021] In the utility model, unless otherwise specifically defined and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0022] Please refer to Figure 1 A continuous casting machine crystallizer water flow redundancy detection device, comprising: a main flow sensor, which is arranged on the water pipeline of the continuous casting machine crystallizer;

[0023] A standby flow sensor is arranged on the water pipeline of the continuous casting machine crystallizer;

[0024] A controller is in communication connection with the main flow sensor and the standby flow sensor, when the main flow sensor fails, the standby flow sensor is switched to measure the flow of the water pipeline of the continuous casting machine crystallizer. When the controller receives that the flow of the water pipeline of the continuous casting machine crystallizer exceeds the set threshold, an alarm is sent, and the alarm information is uploaded to the upper computer through the communication module.

[0025] Further, as Figure 1 The main flow sensor 1 is a flange type electromagnetic flowmeter with a pipe diameter of 240mm, and the installation position is at the position of 5 / 8 of the horizontal section from the water inlet direction;In addition, the other is a standby flow sensor 2, which is an insertion type electromagnetic flowmeter, which is installed at the position of 1 / 3 of the horizontal section from the water inlet direction, and a circular hole with a diameter of 50mm is opened, and the electromagnetic flowmeter is installed on the hole. The main reason for using electromagnetic flowmeter for the main sensor is that the relative accuracy of electromagnetic flowmeter is high. The main reason for using insertion type flowmeter for standby sensor is that the accuracy is relatively low, which can realize temporary crystallizer water flow detection, and the insertion type flowmeter has no requirement for installation position.

[0026] As Figure 2When the main flow sensor has a hardware failure, the backup flow sensor is switched to, and the crystallizer water flow is controlled by using the backup flow sensor measurement value; if the main flow sensor has no hardware failure, whether the crystallizer water flow is alarmed is judged again, and if the alarm occurs, the crystallizer water flow is controlled by using the backup flow sensor measurement value.

[0027] According to the specific embodiments provided by the utility model, the following technical effects are disclosed:

[0028] The utility model discloses a main flow sensor and backup flow sensor can be set, can switch to the backup sensor when the main sensor appears the failure, thereby ensuring the continuity and reliability of flow measurement, avoids the downtime or production delay caused by sensor damage.
