Embodiment Construction

[0020] A method for measuring the temperature and position of the combustion zone of the sintered bed provided by the present invention comprises the following steps:

[0021] S1. Before starting the sintering process, initialize the measuring device;

[0022] S2. When the sintering starts, the measuring device starts to work at the same time, and returns the measured temperature value and displacement in real time;

[0023] S3. The control computer compares the recorded real-time temperature parameters, and when an extreme value occurs, it sends a control command to change the state of the control switch 10, and records the displacement parameter D at the same time i , running time t i and the peak temperature T i ; Wherein, i is the number of times that the state of the control switch 10 changes;

[0024] S4. The operation of the above step S3 is repeated cyclically until the sintering is completed.

[0025] The method of the present invention will be further described b...

Abstract

The invention discloses a method and a device for measuring the position and temperature of a combustion zone in a sinter bed. The method comprises the following steps of: determining the position of the combustion zone by tracking the highest temperature of the combustion zone; and determining the instantaneous speed at the moment and the average speed of the whole process by recording the actual temperature, displacement and time, and controlling the sintering process by taking the instantaneous speed and the average speed as production control guidance. In order to implement the measuring method, the invention discloses the measuring device matched with the measuring method, wherein sensors arranged inside a sintering cup can be used for measuring the real-time temperature and displacement parameters and transmitting the real-time temperature and displacement parameters back to a computer, and the computer is used for doing corresponding calculations and sending control signals.

Description

technical field [0001] The invention relates to the technical field of temperature measurement and positioning of a combustion zone in a sintering material bed of a sintering machine, in particular to a method and a device for positioning a combustion zone through temperature tracking. Background technique [0002] During the sintering process, the combustion zone of the material layer moves from top to bottom, that is, the process from the generation and condensation of the sintering liquid phase to the finished sintered ore. Therefore, the moving speed of the combustion zone and the temperature of the combustion zone have a crucial influence on the quality of sinter and various sintering indexes. If the temperature of the combustion zone is too low, enough liquid phase cannot be generated to consolidate the unmelted particles, so that the strength of the sintered ore is low and the yield rate decreases; formation of calcium ferrite. Therefore, the real-time temperature a...
