Embodiment Construction

[0026] see figure 1 , the method of the present invention comprises the steps of:

[0027] In the first step, the process control system judges whether there is an iron receiving signal in the iron receiving process of the blast furnace, and gives the correct order of the first iron receiving start signal and the iron tapping start signal when there is an iron receiving signal.

[0028] There are three situations in the blast furnace iron receiving process: first, there is no iron receiving signal (the iron receiving signal includes the iron receiving start signal and the iron receiving end signal); second, there is an iron receiving signal, and the correct sequence is the first iron receiving start signal In the front, the iron tapping start signal is behind; third, there is the iron receiving signal; the correct sequence is that the iron tapping start signal comes first, and the first iron receiving start signal follows. These three situations are confirmed by this step, an...

Abstract

The invention discloses a process control method for iron discharge and reception of a blast furnace. The method is based on three conditions under which the iron discharging data, the corresponding iron receiving data, and the representative values and the average values of components, weights and temperatures of molten iron of the discharging iron and the corresponding receiving iron are recorded. The method of the invention realizes a general modeling operation for the iron discharge and receiving processes of the blast furnace in different production environments and satisfies the demandsof various iron-making enterprises.

Description

technical field [0001] The invention relates to a process control method for blast furnace ironmaking. Background technique [0002] Blast furnace ironmaking is a complex physical and chemical process, which can be roughly described as: loading iron ore, fuel and solvent from the upper part of the furnace body; blowing high-temperature oxygen-enriched air from the lower part of the furnace body to burn the fuel, generating a large amount of high-temperature reducing The gas moves upwards; the charge on the upper part of the furnace body undergoes a series of processes such as heating, reduction, melting, and slagging during its descent, and finally generates liquid slag and molten iron. [0003] Through the taphole, the blast furnace regularly discharges the molten iron and liquid slag from the furnace body, and the opening of the taphole to the closing of the blast furnace is one tapping (Tap). When tapping the blast furnace, the iron cans (also known as torpedo cans, iron...
