Description

Technical Field

[0002] The processes for heat-treating steel plates generally include normalizing, tempering, annealing, quenching, etc. Among them, when tempering a steel plate using a roller hearth tempering furnace, since it is necessary to control the accuracy deviation between the actual temperature and the target temperature in the roller hearth tempering furnace not to exceed 5 - 10°C, it is necessary to ensure good airtightness of the roller hearth tempering furnace. However, the roller hearth tempering furnace uses gas as fuel for the tempering process. During the combustion of gas, due to impurities such as dust and moisture, they are easily condensed into tar, and the tar will block the burners of the roller hearth tempering furnace, causing the gas to freely disperse into the roller hearth tempering furnace. When the furnace is stopped or the temperature is lowered and the burners are closed, the gas leaked from the burners becomes the main cause of the explosion of the roller hearth tempering furnace, posing a great safety hazard. Therefore, it is necessary to clean the burners in a timely manner. However, at present, the cleaning work of the burners can only be carried out by manually checking the blocked burners one by one. The number of burners in the roller hearth tempering furnace is relatively large, resulting in difficulties in checking the burners, and large maintenance time and maintenance costs.

[0024] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present application.

[0025] In order to illustrate the technical solutions described in the present application, the following will be described through specific embodiments.

[0026] A burner is a common name for the combustion device used in industrial fuel furnaces. Generally, it refers to the main body part of the combustion device, which has a fuel inlet, an air inlet, and a spray hole, and plays a role in distributing fuel and combustion-supporting air and burning after spraying in a certain manner. The roller hearth tempering furnace uses gas as fuel for the tempering process. During the gas combustion process, since impurities such as dust and moisture in the environment are easily condensed into tar, the tar will block the burners of the roller hearth tempering furnace, causing the gas to freely disperse into the roller hearth tempering furnace. When the furnace is stopped or the burner is closed, the negative pressure is caused in the roller hearth tempering furnace due to the temperature drop, and air enters the roller hearth tempering furnace. When the roller hearth tempering furnace ignites and operates, the gas leaked from the burner mixes with the air, causing an explosion in the roller hearth tempering furnace.

[0027] In order to avoid the problem of explosion of the roller hearth tempering furnace caused by burner blockage, the prior art often checks the blockage situation of all burners of the roller hearth tempering furnace one by one manually. However, the number of burners on the roller hearth tempering furnace is large, and it is impossible to quickly and accurately locate the specific position of the burner, resulting in relatively large labor and maintenance time costs.

[0028] Based on the problems existing in the prior art, the embodiments of the present application provide a safety detection method, device, equipment, and storage medium for a roller hearth tempering furnace. By obtaining the gas concentration at different regional positions of the roller hearth tempering furnace, it is determined whether the gas concentration is within the explosion range to determine the explosion position of the roller hearth tempering furnace, and then the specific position of the burner causing the explosion of the roller hearth tempering furnace is quickly located, and the burner is cleaned in time, solving the problem that the prior art consumes a large amount of manpower and maintenance time for checking all burners one by one; and using the warning range and the explosion range to achieve hierarchical warning of the explosion situation, so that users can take effective countermeasures for different explosion situations.

[0029] AsFigure 1 and Figure 2 As shown in Figure 2 , the first aspect of the embodiment of the present application provides a safety detection method for a roller hearth tempering furnace, including the following steps:

[0030] S101. Obtain the gas concentrations at multiple regional positions of the roller hearth tempering furnace, where the regional positions include at least one burner.

[0031] It can be understood that for a gas explosion to occur, three factors must be present: a confined space, a concentration reaching the explosion limit, and an open flame. For a roller hearth tempering furnace, the roller hearth tempering furnace is a confined space. When the gas concentration reaches the explosion range, an explosion will occur when the burner of the roller hearth tempering furnace is ignited. Therefore, in the embodiment of the present application, during the shutdown of the roller hearth tempering furnace or when the burner is closed, it is detected whether the gas concentration at different regional positions inside the furnace reaches the explosion range, and maintenance measures are taken in a timely manner to avoid an explosion during the ignition operation of the roller hearth tempering furnace, which endangers life and property safety.

[0032] In an alternative embodiment, obtaining the gas concentrations at multiple regional positions of the roller hearth tempering furnace includes:

[0033] Obtain at least two gas concentrations at three regional positions, namely the front, middle, and rear of the roller hearth tempering furnace respectively;

[0034] Determine the gas concentrations at the three regional positions of the front, middle, and rear respectively according to the average values of the at least two gas concentrations.

[0035] In the embodiment of the present application, the roller hearth tempering furnace is divided into multiple regional positions, and the gas concentrations at each regional position are detected. In the case where the number of burners of the roller hearth tempering furnace is large, the position of the explosion of the roller hearth tempering furnace can be quickly and effectively located. Exemplarily, the roller hearth tempering furnace is divided into three regional positions, namely the front, middle, and rear. Specifically, two gas concentrations are obtained on both sides of the front regional position, two gas concentrations are obtained on both sides of the middle regional position, and two gas concentrations are obtained on both sides of the rear regional position. The average values of the two gas concentrations are calculated respectively as the gas concentrations at the front regional position, the middle regional position, and the rear regional position. In the embodiment of the present application, the gas concentrations are obtained at the front, middle, and rear three regional positions of the roller hearth tempering furnace. The obtained data range fully covers the roller hearth tempering furnace, and the gas concentration at the regional position is determined according to the average value of the multiple gas concentrations at each regional position, so that the gas concentration can better reflect the overall characteristics and reduce the error caused by a relatively high gas concentration at a certain point. It can be understood that in practical applications, according to the actual length and application requirements of the roller hearth tempering furnace, it is not limited to obtaining the gas concentrations at the three regional positions of the front, middle, and rear listed in the embodiment of the present application, nor is it limited to obtaining two gas concentrations at each regional position.

[0036] It should be noted that the gas concentration refers to the concentration of gas in the air. By taking gas samples at different regional positions in the roller hearth tempering furnace and measuring and calculating the sampled gas samples, the gas concentration at the corresponding regional positions can be obtained.

[0037] S102. When the gas concentration is within a preset first warning range or a preset second warning range, an alarm message is sent. The upper limit of the first warning range is less than the lower limit of the second warning range.

[0038] In the embodiment of the present application, the first warning range and the second warning range refer to the concentration ranges of gas that may cause the explosion of the roller hearth tempering furnace. Respectively judge whether the gas concentrations at the above-mentioned three regional positions of the front, middle, and rear are within the first warning range or the second warning range. If the gas concentration is within the first warning range or the second warning range, it means that the gas concentration at this time is close to the gas explosion concentration, and it is necessary to send an alarm message in time to alert the operator, so that the operator can perform real-time detection on the regional position to prevent the explosion of the roller hearth tempering furnace caused by sudden changes in the gas concentration.

[0039] In an alternative embodiment, after sending the alarm message, it further includes:

[0040] Conduct an explosion experiment on the gas within the preset first warning range or the preset second warning range to determine whether the gas explodes;

[0041] If an explosion occurs, clean the burners at the regional position.

[0042] In the embodiment of the present application, when there are various reasons such as improper operation, changes in the operation level due to personnel replacement, or changes in the environmental concentration in the steel plant, the gas concentration at the regional position may change accordingly, which may cause the explosion of the roller hearth tempering furnace. It is necessary to further determine whether the gas concentration reaches the explosion range, and then clean the burners in time to eliminate the explosion risk. Therefore, it is necessary to further conduct an explosion experiment on the gas within the first warning range or the second warning range to determine whether an explosion will occur. If an explosion occurs, the burners at the regional position need to be cleaned to ensure the safety of the roller hearth tempering furnace.

[0043] S103. When the gas concentration is within a preset explosion range, an explosion message is sent, and the burners at the regional position are cleaned. Among them, the upper limit of the explosion range is less than or equal to the lower limit of the second warning range, and the lower limit of the explosion range is greater than or equal to the upper limit of the first warning range.

[0044] In an alternative embodiment, cleaning the burners at the regional position includes:

[0045] Obtain the blockage degree of the burners at the regional position;

[0046] Determine whether the blockage degree of the burner is greater than or equal to a preset blockage threshold;

[0047] If the blockage degree of the burner is greater than or equal to the preset blockage threshold, clean the burner.

[0048] In the embodiment of the present application, the explosion range refers to the concentration range in which the gas concentration will definitely cause an explosion in the roller hearth tempering furnace. The upper limit of the explosion range is less than or equal to the lower limit of the second warning range, and the lower limit of the explosion range is greater than or equal to the upper limit of the first warning range. The industry has proposed a theoretical explosion limit for each gas component. However, in actual industrial applications, due to various factors such as the operation level of personnel, the environment of the steel plant, and the actual quality of the gas, the explosion range is not equal to the theoretical explosion limit. The determination of the explosion range in the embodiment of the present application can be achieved by taking multiple samples of the gas in the roller hearth tempering furnace, conducting explosion experiments on the sampled gas, and then determining the explosion range. It can also refer to other methods for determining the explosion range in the prior art, which is not limited in the embodiment of the present application.

[0049] In the embodiment of the present application, if the gas concentration is within the explosion range, it is necessary to clean the burner at the position of this area in a timely manner. Further, by detecting whether the blockage degree of the burner at the position of this area is greater than or equal to the preset blockage threshold, if the blockage degree of the burner is greater than or equal to the preset blockage threshold, clean the burner. Among them, the detection of the blockage degree of the burner can adopt methods such as detecting the thickness of the burner or other methods. For details, reference can be made to the prior art, which is not limited in the embodiment of the present application.

[0050] It can be understood that in the embodiment of the present application, when it is judged that the gas concentration is within the explosion range, it is possible to quickly locate the area where the roller hearth tempering furnace explodes intelligently, and it is only necessary to clean the burner at the position of this area, without checking each burner of the roller hearth tempering furnace one by one; then, according to the blockage degree of the burner in this area, clean the burner with a serious blockage degree specifically, eliminate the danger of explosion caused by burner blockage, and further save manpower and maintenance time.

[0051] In the embodiment of the present application, hierarchical warnings are set according to the first warning range, the second warning range, and the explosion range, so that users can take timely and effective countermeasures according to the explosion situation. When the gas concentration is within the first warning range or the second warning range, the gas concentration at the position of this area is close to the explosion concentration, and it is necessary to send a warning message in a timely manner to alert the operator, so that the operator can perform real-time detection on the position of this area to prevent the explosion of the roller hearth tempering furnace caused by sudden changes in the gas concentration; when the gas concentration is within the explosion range, the gas at the position of this area will definitely cause an explosion in the roller hearth tempering furnace, and it is necessary to send an explosion message to prompt the operator to clean the burner in a timely manner.

[0052] The embodiments of the present application can not only quickly locate the position of the burner, prevent the explosion of the roller hearth tempering furnace caused by burner blockage, but also optimize the combustion quality of the gas in the roller hearth tempering furnace and improve the combustion efficiency of the gas on the basis of preventing the explosion of the roller hearth tempering furnace, so as to achieve the best effect of steel tempering.

[0053] In an alternative embodiment, after cleaning the burner at the regional position, it further includes:

[0054] Obtaining the combustion temperature, combustion time and gas consumption of the gas in the roller hearth tempering furnace;

[0055] Obtaining the gas ratio in the roller hearth tempering furnace according to the gas concentration at the regional position;

[0056] Adjusting the gas ratio in the roller hearth tempering furnace according to the combustion temperature, combustion time and gas consumption.

[0057] In an alternative embodiment, adjusting the gas ratio in the roller hearth tempering furnace according to the combustion temperature, combustion time and gas consumption includes:

[0058] Obtaining the theoretical combustion temperature, theoretical combustion time and theoretical gas consumption when the gas burns sufficiently;

[0059] Adjusting the gas ratio in the roller hearth tempering furnace so that the combustion temperature, combustion time and gas consumption reach the theoretical combustion temperature, theoretical combustion time and theoretical gas consumption when the gas burns sufficiently.

[0060] As described above, after eliminating the explosion risk of the roller hearth tempering furnace, the roller hearth tempering furnace starts to work, and the gas concentration at each regional position of the roller hearth tempering furnace is obtained; through the analysis and calculation of the gas concentration, the ratio of various gas components in the roller hearth tempering furnace can be obtained. It can be understood that the gas components in the roller hearth tempering furnace include blast furnace gas, coke oven gas, converter gas and other gas components. In the tempering process, different tempering temperatures are provided for steel by controlling the ratio of blast furnace gas, coke oven gas, converter gas and other gases.

[0061] Specifically, the embodiments of the present application optimize the combustion quality of the gas by adjusting the ratio of various gas components to ensure the full combustion of the gas. The industry stipulates the optimal air-fuel ratio for the full combustion of various gas components. At the optimal air-fuel ratio, the theoretical combustion temperature, theoretical combustion time, and theoretical gas consumption corresponding to the gas are determined. The embodiments of the present application use a thermometer to detect the combustion temperature in the roller hearth tempering furnace, use a timer to obtain the combustion time in the roller hearth tempering furnace, and use a flow valve to obtain the consumption of various gases; by the control method of single variable, the ratio of the gas in the roller hearth tempering furnace is adjusted to make the combustion temperature, combustion time, and gas consumption in the roller hearth tempering furnace reach the theoretical combustion temperature, theoretical combustion time, and theoretical consumption.

[0062] Exemplarily, the roller hearth tempering furnace includes blast furnace gas, coke oven gas, and converter gas. The ratio of the three gases is obtained by analyzing the obtained gas concentration; at the optimal air-fuel ratio of blast furnace gas, coke oven gas, and converter gas, assuming the theoretical combustion temperature of the roller hearth tempering furnace is 100 °C and the theoretical gas consumption is 100 m 3 , and the theoretical combustion time is 100 min; the single control variable method is used to control the combustion temperature in the roller hearth tempering furnace to 100 °C and control the gas consumption input into the roller hearth tempering furnace to 100 m 3 , and at this time, the timer obtains the combustion time of the gas as 110 min; by adjusting the ratio of blast furnace gas, coke oven gas, and converter gas, the combustion time reaches 100 min. Similarly, control the combustion temperature in the roller hearth tempering furnace to 100 °C, control the combustion time of the gas to 100 min, adjust the ratio of the three gases, and make the gas consumption obtained by the flow valve 100 m 3 , or control the combustion time in the roller hearth tempering furnace to 100 min, control the gas consumption input into the roller hearth tempering furnace to 100 m 3 , adjust the ratio of the three gases, and make the combustion temperature obtained by the thermometer 100 °C. Continuously adjust the ratio of the three gases to make the combustion time, combustion temperature, and consumption reach the theoretical combustion time, theoretical combustion temperature, and theoretical consumption at the optimal air-fuel ratio.
