Problems solved by technology

[0003] 1. Due to the product characteristics of the master controller, it is very difficult to debug the two master control points at 0 degrees of the converter into a sharp signal. In this way, it will inevitably cause the converter angle displayed in an angle area are all 0 degrees
[0004] 2. Because the encoder of the converter may deviate during the rotation process, there may still be angle errors in non-0-degree areas such as the tapping hole, and this angle error will have a great impact on production

Abstract

The invention relates to automatic correcting error control on converter tilting angle. Included is a PLC (Programmable Logic Controller) control, a rotary encoder and a master controller. The master controller is provide with four master controller control points; a first master controller control point is arranged in an area, which forms by the converter rotating clockwise 0-30 DEG towards a direction in front of the furnace; a second master controller control point is arranged in an area, which forms by the converter rotating 30-50 DEG anticlockwise towards a direction behind the furnace; a third master controller control point is arranged in an area, which forms by the converter rotating 340-360 DEG anticlockwise towards a direction behind the furnace; and a fourth master controller control point is arranged in an area, which forms by the converter rotating 270-300 DEG clockwise from furnace back to front. According to a technical scheme of the invention, control point can be arranged easily near each master controller control point angle, and are corrected by signal level and a rotary encoder of each master controller control point to eliminate deviation, so as to ensure needs of production technology and omit subsequent maintenance after debug.

Description

technical field [0001] The invention relates to a steelmaking converter process equipment in the metallurgical industry, in particular to an automatic deviation correction control method for a converter tilting angle. Background technique [0002] The tilting angle control of the converter is generally calculated by the PLC according to the pulse number of the encoder, and two control points of the master controller are set at 0 degrees of the converter. When the signals of the two master controllers are both 1 or 0, the converter is displayed. 0 degrees, according to which to check the converter angle calculated by the encoder. This control method has the following disadvantages: [0003] 1. Due to the product characteristics of the master controller, it is very difficult to debug the two master control points at 0 degrees of the converter into a sharp signal. In this way, it will inevitably cause the converter angle displayed in an angle area It's all 0 degrees. [0004...
