Embodiment Construction
[0033] see figure 2 , is a schematic flowchart of a method for calculating the tilting angle of a blast furnace chute provided in the embodiment of the present application, as shown in figure 2 As shown, a method for calculating the tilting angle of a blast furnace chute provided in the embodiment of the present application specifically includes the following steps:
[0034] Step S110: Obtain the real-time Gray code value output by the encoder.
[0035] Specifically, the encoder is an absolute encoder connected to the motor. According to its own precision, such as 12 bits, 14 bits, 17 bits, etc., the encoder automatically outputs the Gray code value of the corresponding number of bits within a scan cycle (usually 10ms). In this embodiment, the encoder outputs a 12-bit Gray code value every 10 ms. Correspondingly, the digital quantity module of the PLC (Programmable Logic Controller, programmable logic controller) receives the Gray code value output by the encoder every o...

The invention provides a method for calculating a tilting angle of a chute of a blast furnace. The method comprises the steps of obtaining a real-time Gray code value output by an encoder; convertingthe real-time Gray code value into a real-time integer code value; judging whether a linear code value interval containing the real-time integer code value exists or not; and if yes, obtaining a linear function between the integer code value in the linear code value interval and the tilting angle, and according to the linear function and the real-time integer code value, obtaining the real-time tilting angle corresponding to the real-time integer code value. According to the method for calculating the tilting angle of the chute of the blast furnace, the real-time tilting angle is calculated out according to the linear function, so that the calculation efficiency of the tilting angle can be effectively improved; and the real-time tilting angles corresponding to all integer code values in the linear code value interval can be calculated, so that the continuity and stability of tilting angle calculation are improved.
Description
technical field [0001] The present application relates to the field of the metallurgical industry, in particular to a method for calculating the tilting angle of a blast furnace chute. Background technique [0002] During the blast furnace material distribution process, the material in the distributor reaches the furnace through the chute, and there is an angle between the axis of the distributor and the axis of the chute, which is called the inclination angle of the chute. Adjusting the tilting angle can change the position of the pile tip of the cloth, thereby changing the radial distribution of the charge in the furnace and the shape of the charge surface, which is of great significance to reducing the consumption of cloth and increasing the production capacity of the blast furnace. [0003] see figure 1 , is a structural schematic diagram of a tilting angle adjustment system, such as figure 1 As shown, the system includes a computer, programmable logic controller, enco...
