Problems solved by technology

[0003] The problem to be solved by the present invention is to provide an iron ore powder assimilation temperature detection system that simulates different conditions, which can solve the problem that the temperature of the gas passing into the heating furnace is too different from the temperature in the heating furnace, which will cause temperature fluctuations in the heating furnace , and the lens of the camera is easily damaged, which affects the clarity of the camera to capture the assimilation process of the sample, thus affecting the accuracy of the assimilation temperature detection

Embodiment 1

[0021] Such as figure 1 , figure 2 A temperature detection system for iron ore powder assimilation that simulates different conditions is shown, including a heating furnace 8, a gas supply device, a camera 2 and a computer 1, the computer 1 is connected to the camera 2 in communication, and the heating furnace 8 is connected through a preheating component 17 The gas supply device includes two gas cylinders 20, the gas cylinders 20 are equipped with flow control valves 19, the two flow control valves 19 are connected to the flow meter 18 through the gas pipe, and the flow meter 18 is connected to the preheating component 17 through the gas pipe. Two flow control valves 19 control the gas to pass into the heating furnace 8 after being preheated according to a certain ratio and flow rate. By adjusting the gas flow rate of different gas cylinders 20, the partial pressure of oxygen in the gas can be adjusted, and then different reaction atmospheres can be adjusted. A support 13 i...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that a scale is provided on the slide rail 12 along its length direction, and an indicator mark is provided on the slide block 11. When the cross strut 5 just enters the heating furnace 8, the The index mark is aligned with the zero point of the scale on the slide rail 12, such as Figure 4 shown. Thereby can accurately judge the position where the iron ore powder sample 16 enters the furnace cavity of the heating furnace 8, guarantee that the iron ore powder sample 16 is sent to the constant temperature zone of the heating furnace 8 furnace cavity, because the temperature fluctuation in the constant temperature zone is small, the assimilation process can be improved. Accuracy of temperature detection. In addition, during the continuous experiment, the iron ore powder sample 16 can be pushed into the furnace chamber of the heating furnace 8 in stages, so as to meet the dual effects of preheating in the early st...

Abstract

The invention discloses a system for simulating the detection of an assimilation temperature of an iron ore powder under different conditions, and relates to the technical field of detection of the basic characteristic of the iron ore powder. The system comprises a heating furnace, an air supply device, a video camera and a computer, the computer is in communication connection with the video camera, the heating furnace is connected with the air supply device through a preheating part, a bracket is arranged between the heating furnace and the video camera, a horizontal support rod for placing an iron ore powder sample is arranged on the bracket and extends into a furnace chamber of the heating furnace, a temperature measurement part for detecting the temperature of the iron ore powder sample is arranged on the horizontal support rod and is in communication connection with the computer, a camera lens of the video camera is aligned with the iron ore powder sample on the horizontal supportrod, and a pair of camera lens protective glass is arranged in front of the camera lens of the video camera. Compared with the prior art, the fluctuation of the temperature in the heating furnace isreduced, the high temperature gas in the heating furnace is prevented from directly convecting on the camera lens of the video camera, to ensure the definition of the video camera in the process of capturing the assimilation of the sample, so that the accuracy of detection of the assimilation temperature is improved.

Description

technical field [0001] The invention relates to the technical field of iron ore powder basic characteristic detection, in particular to a detection system for iron ore powder assimilation temperature that simulates different conditions. Background technique [0002] Iron ore sintering is an important process to provide ironmaking raw materials with excellent metallurgical properties for blast furnaces. Since the properties of iron ore powders from different sources are very different, they need to be used in a reasonable combination to meet the requirements of blast furnace production for sinter. At present, it is common to use different iron ore powders reasonably through research on the basic properties of iron ore powders. In the process of testing the basic performance data of iron ore powders, such as testing the assimilation reaction performance of iron ore powders and CaO, testing the liquid phase fluidity of iron ore powders, and When the strength of iron ore powder...
