Method for improving tapping rate of converter

Abstract

The invention discloses a method for improving the tapping rate of a converter, , a converter internal temperature estimation problem is converted into a blowing operation and tapping rate correlationproblem, the problem that the converter internal temperature cannot be measured is solved, errors caused by inaccurate converter internal temperature measurement are avoided, and the method specifically comprises the steps that S10, establishing a production guidance model including production items, wherein the production items comprise N parallel steel grade options; S20, learning historical production records, dividing the historical production records by taking different steel types as classification indexes, and learning production material parameters, production operation parameters andtapping rates in the historical production records under each steel type option; S30, inputting a steel grade to be produced in actual production, and matching the steel grade to a steel grade optioncorresponding to a production item in the production guidance model; and inputting production material parameters in actual production, matching the production material parameters with the same production material parameters in the production guidance model learning record, and outputting corresponding production operation parameters and steel tapping rate.

Description

technical field [0001] The invention relates to the technical field of production management, in particular to a method for increasing the steel tapping rate of a converter. Background technique [0002] In the iron and steel production industry, the oxygen top-blown converter is a widely used steelmaking furnace, which has the characteristics of fast production speed, suitable for many varieties and good quality. [0003] The furnace temperature of the converter is an important indicator of the steelmaking process, and is an important basis for the decision-making of the amount of coolant input, input time, and oxygen blowing operation, but it is also an unmeasurable indicator (the current furnace temperature is obtained based on color comparison, Or calculated by the auxiliary system, the given value is not the actual furnace temperature, there are errors), it can only be based on the experience judgment of the master, this is the core problem of steelmaking enterprises, a...

Problems solved by technology

In the steelmaking process, as the age of the furnace increases, the corrosion of the furnace wall becomes more serious, that is, the furnace wall becomes thinner and the inner diameter of the molten pool becomes larger. The gun position also needs to be lowered synchronously, and because the inside of the furnace is invisible, the adjustment of the oxygen gun position depends entirely on the experience of the front-line workers. The manual adjustment method has poor stability, resulting in poor stability of the tapping rate. Veteran experience method
