An intelligent control method for sintered magnesium oxide

Abstract

The invention relates to an intelligent control method for sintered magnesium oxide, comprising: step (1): calculating the proportion and cutting amount of magnesium-containing flux; step (2): calculating the calculated proportion and cutting amount of magnesium-containing flux The amount is sent to the first-level batching system, and the batching is carried out through the first-level batching system; step (3): calculate the magnesium oxide adjustment value according to the actual batching amount of the first-level batching system and the magnesium oxide target value; step (4): If the deviation between the magnesium oxide adjustment value and the magnesium oxide target value is outside the preset range, then recalculate the proportioning and feeding amount of the magnesium-containing flux according to the magnesium oxide adjustment value, and repeat the steps (2) to step (3), until the deviation between the magnesium oxide adjustment value and the magnesium oxide target value is within a preset range. The invention realizes precise control of magnesium oxide by intelligently controlling the addition of magnesium-containing flux.

Description

Technical field [0001] The present invention relates to the field of magnesium oxide addition technology, in particular to a sintered magnesium oxide intelligent control method. Background [0002] In the process of blast furnace smelting, the content of magnesium oxide in the slag is the main factor affecting its fluidity, and the magnesium oxide of the slag mainly comes from the iron-containing raw materials in the furnace. At present, the main incoming iron for blast furnace smelting is sinter ore, so the control of magnesium oxide of sinter has a great impact on the forward condition of the blast furnace and the quality of production. The main source of magnesium oxide in sinter is mixed ore, return to ore and magnesium-containing flux, when the quality, dosage or production of magnesium-containing flux changes, will cause fluctuations in sinter magnesium oxide, the general enterprise magnesium oxide control is manual adjustment control, completed by manual experience, low ac...

Problems solved by technology

The main sources of magnesia in sinter are mixed ore, returning ore and magnesium-containing flux. When the quality, dosage or production of magnesium-containing flux changes, it will cause fluctuations in sinter magnesia. Generally, the control of magnesia in enterprises is manual adjustment control , completed by manual experience, with disadvantages such as low accuracy, poor timeliness, and poor adaptability, etc., which have a great impact on the next process of the blast furnace.
