A Calculation Method of Converter Tilting Moment

Abstract

The invention discloses a calculation method for calculating the turning torque of a converter. The method comprises the steps of 1) constructing a three-dimensional model for the liquid in a converter along with a turning angle alpha in a three-dimensional system; 2) during the turning process of the converter, dividing the three-dimensional model for the liquid in the converter into two stages: namely before the outflow of the liquid in the converter and after the outflow of the liquid in the converter; 3) calculating the critical turning angle beta of the liquid in the converter for the three-dimensional model when the liquid just flows out of the converter; 4) in the three-dimensional model, when alpha is smaller than or equal to beta, calculating the height h of the liquid in the converter during the turning process of the converter; 5) constructing a three-dimensional model for the liquid in the converter based on alpha and h, and acquiring the turning angle when alpha is smaller than or equal to beta; 6) based on the alpha and h-based three-dimensional model for the liquid in the converter, acquiring the turning torque when beta is smaller than alpha and alpha is smaller than or equal to A; 7) calculating the turning torque of the converter. The method is high in calculation efficiency and ensures the calculation accuracy. Meanwhile, the turning torques of converters of different types can be calculated based on the above method.

Description

technical field [0001] The invention relates to metallurgical steelmaking technology, in particular to a calculation method for the tilting moment of a converter. Background technique [0002] The converter tilting torque is one of the important parameters of the converter tilting mechanism. It is not only an important basis for designing the tilting mechanism, furnace shell, supporting ring and other components, but also an important reference index for equipment safety production and maintenance. The tilting torque of the converter equipment is calculated to determine the position of the trunnion and the rated torque value of the tilting mechanism, so that the equipment can ensure safe production and be economical and reasonable. The tilting moment M of the converter consists of three parts: M=M k +M y +M m , where: M k is the tilting moment of the empty furnace, M y is the tilting moment of the furnace liquid, M m is the friction torque on the converter trunnion.

Problems solved by technology

The traditional calculation methods for the tilting torque of the furnace liquid include: analytical method, slice method, and graphical method. These methods have the following problems: 1) The mathematical calculation model of the converter prototype needs to be simplified before it can be established, so the calculation accuracy is difficult to guarantee; 2 ) is difficult to calculate and the process is cumbersome

There is also a method of using 3D modeling to obtain the physical properties of the model. Although the calculation is easy, the whole process is relatively cumbersome because it needs to interact with the 3D platform repeatedly.
