Problems solved by technology

For example, the hearth is not active, and the hearth of the blast furnace is easy to accumulate, which may affect the forward movement and production indicators of the blast furnace
The activity of the hearth is too high, and the scour of carbon bricks in the hearth is intensified, which is not conducive to the longevity and safety of the blast furnace
However, in the prior art, relevant judgments have not been made on whether the hearth of the blast furnace is good or bad.

Embodiment 1

[0060] In order to facilitate the understanding of this embodiment, the electronic equipment for implementing the method for determining the hearth state of a blast furnace disclosed in the embodiment of the present application is first introduced in detail.

[0061] Such as figure 1 Shown is a block diagram of the electronic device. The electronic device 100 may include a memory 111 , a storage controller 112 , a processor 113 , a peripheral interface 114 , an input and output unit 115 , and a display unit 116 . Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and does not limit the structure of the electronic device 100 . For example, the electronic device 100 may also include a ratio figure 1 more or fewer components than shown in, or with figure 1 Different configurations are shown.

[0062] The memory 111 , storage controller 112 , processor 113 , peripheral interface 114 , input / output unit 115 and displa...

Embodiment 2

[0070] see figure 2 , is a flow chart of a method for determining a state of a blast furnace hearth provided by an embodiment of the present application. The following will be figure 2 The specific process shown will be described in detail.

[0071] Step 201, under the standard state, obtain the state values ​​of multiple state parameters of the target blast furnace within a preset time period.

[0072] Exemplarily, the above-mentioned standard state may refer to a state in which various production indicators of the target blast furnace are relatively good. Optionally, the standard state may be a cycle period when the target blast furnace is in the full-air and full-oxygen smelting state.

[0073] Exemplarily, the multiple state parameters may include: furnace core temperature, molten iron temperature, slag viscosity, tapping time, slag tapping rate, iron amount difference, wind speed, and theoretical combustion temperature.

[0074] Wherein, the furnace core temperature...

Embodiment 3

[0181] Based on the same application concept, the embodiment of the present application also provides a blast furnace hearth state determination device corresponding to the method for determining the state of the blast furnace hearth. Since the problem-solving principle of the device in the embodiment of the present application is the same as that of the above-mentioned blast furnace hearth in the embodiment of the present application The method for determining the state is similar, so the implementation of the device can refer to the implementation of the method, and the repetition will not be repeated.

[0182] see Figure 5 , is a schematic diagram of the functional modules of the device for determining the hearth state of the blast furnace provided in the embodiment of the present application. Each module in the device for determining the hearth state of the blast furnace in this embodiment is used to execute each step in the above method embodiment. The blast furnace hea...

Abstract

The invention provides a blast furnace hearth state determination method and device and electronic equipment. The blast furnace hearth state determination method comprises the steps: under a standardstate, obtaining state values of multiple state parameters of a target blast furnace in a preset time period (in a standard state, acquiring state values of multiple state parameters, related to the blast furnace hearth state, of the target blast furnace in a preset time period), wherein the multiple state parameters comprise a parameter for representing the hearth bottom heat level of the targetblast furnace, a parameter for representing the hearth heat level in the smelting period, a parameter for representing the blast furnace tuyere front end heat level and a parameter for representing the synchronism of discharging molten iron and generating molten iron by blast furnace smelting; calculating standard state values corresponding to the multiple state parameters according to the parameter values of the plurality of state parameters; collecting real-time state values of the multiple state parameters of the target blast furnace at a target time; and calculating a hearth activity indexof the target blast furnace according to the real-time state values and the standard state values of the multiple state parameters.

Description

technical field [0001] The present application relates to the field of smelting technology, in particular, to a method, device and electronic equipment for determining the state of a blast furnace hearth. Background technique [0002] The hearth of the blast furnace is the most important part of the blast furnace body, and the working state of the hearth is directly related to the smooth running, safety and longevity of the blast furnace. For example, the hearth is not active, and the hearth of the blast furnace is easy to accumulate, which may affect the forward movement and production indicators of the blast furnace. If the activity of the hearth is too high, the scour of carbon bricks in the hearth will be intensified, which is not conducive to the longevity and safety of the blast furnace. However, in the prior art, relevant judgments are not made on whether the working state of the hearth of the blast furnace is good or bad. Contents of the invention [0003] In vie...
