Problems solved by technology

[0002] During the normal production of the blast furnace, sometimes there will be a failure of the blast furnace roof probe. This situation makes the operation of the blast furnace difficult. Generally, most operators choose to shut down the production and continue production after the furnace roof probe fault is restored. The process of shutting off the wind and returning to the wind is bound to affect the furnace condition of the blast furnace, thereby affecting the production cost of the blast furnace

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] The real-time material line is calculated once per minute. The calculation is based on the carbon balance in the blast furnace. The sources of carbon in the blast furnace are divided into two categories. Moreover, the consumption of carbon element, that is, the gasification reaction, is carried out in the high-temperature zone of the tuyere of the blast furnace. The metallurgical principle believes that when the carbon element is incompletely burned in the high-temperature zone of the blast furnace, the carbon element is sufficient and excess, and the amount of carbon element consumed by the ...

Abstract

The invention relates to a method for computing real-time stockline of a blast furnace. The method comprises the following steps: computing the oxygen amount o of a tuyere zone; computing the weight V of required dried cokes for burning in the tuyere zone; computing the falling head C of material batches in the furnace; computing the height P of a material batch newly added into the furnace; and computing the latest stockline X. The invention also relates to a device for computing the real-time stockline of the blast furnace by using the method, and the device comprises a sensor for acquiring different data, a PLC controller, a data analysis server and a display. By adopting the method and the device provided by the invention, the charge level height position in the blast furnace is computed according to carbon balance of blast furnace smelting and combining information including operation air volume of the blast furnace, crude fuel structures and the like, so that the problem of damping down caused by stock rod faults at the top of the furnace during blast furnace production is solved, and a guarantee for long-term stable running of the blast furnace and cost conservation is provided.

Description

technical field [0001] The invention relates to the technical field of blast furnace operation, in particular to the field of detecting the position of the material level in the blast furnace. Background technique [0002] During the normal production of blast furnaces, sometimes there will be failures of blast furnace roof probes. This situation makes the operation of blast furnaces difficult. Generally, most operators choose to shut down the production and continue production after the failure of furnace roof probes recovers. However, the process of shutting off the wind and returning to the wind will inevitably affect the blast furnace condition, thereby affecting the production cost of the blast furnace. Contents of the invention [0003] In order to solve the furnace condition fluctuation caused by the failure of the blast furnace roof probe and the wind shutdown, the invention provides a method for calculating the real-time material line of the blast furnace and a de...
