Problems solved by technology

When the underground stockyard feeds the high-level silo, the operator must go to the site to manually confirm the material level of the silo, estimate the weight that can be loaded, and then load the material. Manual estimation has great uncertainty and error, which may easily lead to insufficient material loading. Or laying materials, etc., will affect the production of the converter, so the operator needs to check the material level during the feeding process
There is a lot of dust on site, and the environment is extremely harsh, so it is not suitable for personnel to stay for a long time

Embodiment 1

[0122] Embodiment 1: see Figure 1-Figure 5 , a method for processing the material level of a steelmaking high-level silo, the processing method comprising the following steps: 1) calculating the volume of the silo;

[0123] Since the highest point of the material level is the position of the discharge port, it is not suitable to install the material level detection device. Generally, it is selected at a position slightly away from the discharge port to detect the lower material, so as to avoid the vibration during discharge from affecting the accuracy of the material level detection device. , Also avoid damage to the material level detection device when stacking.

[0124] According to the shape of the silo, the silo is divided into an upper cube and a lower platform. As shown in the figure, the silo is divided into 6 planes, which are A, A0, A1, A2, A3, and A4 planes. The A0 plane is the set material level O plane, and the A2 plane is the material level detection device. Ma...

Abstract

The invention relates to a method for treating the material level of a steel-making overhead bunker. The method for treating the material level includes the following steps of 1), calculation of the volume of the bunker; 2), calculation of the virtual density; 3), calculation of the weights of materials in the bunker; 4), material level alarming setting of the bunker; 5), material level alarming output; 6), display of material level information; and 7), loading priority calculation. By means of the method, the material level of the materials in the overhead bunker of a converter is calculated, current materials in the bunker are grasped in real time, data are provided for automatic loading, the judgment error of an operator on the material level of the bunker is reduced, the loading accuracy is improved, stacking caused by insufficient loading or excessive loading is avoided, and the labor efficiency is improved.

Description

technical field [0001] The invention relates to a processing method, in particular to a method for processing the material level of a high-level feed bin of a converter, and belongs to the technical field of automatic control. Background technique [0002] At present, Meishan Iron and Steel has two steelmaking plants with a total of 5 converters. During the converter steelmaking process, auxiliary materials such as lime and alloy raw materials need to be added. All auxiliary materials and alloys are transported by belts from the underground stockyard and added to the high-level silo. When the underground stockyard feeds the high-level silo, the operator must go to the site to manually confirm the material level of the silo, estimate the weight that can be loaded, and then load the material. Manual estimation has great uncertainty and error, which may easily lead to insufficient material loading. Or laying materials, etc., will affect the production of the converter, so the o...
