Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] Such as figure 1 As shown, L1 represents the basic automation control system, which mainly controls the actions of related equipment; L2 represents the process control system. Each module and its function:

[0024] L2 static control module: Calculate the amount of oxygen blowing and auxiliary materials added to the furnace according to the amount of molten iron smelted, the amount of scrap steel, the temperature and composition of molten iron, and the target composition and temperature at the end of smelting;

[0025] L2 dynamic control module: according to the measured value in the middle...

Abstract

The invention relates to a full-automatic control system and a full-automatic control method for a converter single-slag process. The method comprises the following steps: (1) preparing automatic control in a smelting process, namely selecting a control mode of associated modules and collecting base information; (2) starting a converting start switch, collecting the associated data by virtue of an L2 data collecting module, starting an L2 oxygen lance control process, an L2 charging control process, an L2 sub lance control process, an L2 bottom-blowing control process and a blowing stopping and lance-lifting control process. The full-automatic control system and the full-automatic control method for the converter single-slag process have the beneficial effects of simple structure, convenience in use, automatic control on the oxygen lance, the sub lance, charging and bottom-blowing, lowered labor intensity of the operation staff, high smelting end point control precision, shortened smelting period and lowered production cost.

Description

technical field [0001] The invention relates to the technical field of converter steelmaking, in particular to a converter single slag automatic control system and method. Background technique [0002] Converter steelmaking single slag smelting, scrap steel and molten iron are added to the converter, top and bottom blowing are used, material is added in the middle process, and sub-lance is measured. When the composition and temperature of molten steel meet the requirements, the blowing is stopped after raising the gun, and then the steel is tapped. The traditional smelting process is mainly controlled manually. On-site operators operate the oxygen lance, bottom blowing, sub-lance measurement, and feeding according to the smelting process. When the composition and temperature of molten steel meet the requirements, the lance is lifted to stop blowing, and then the steel is tapped. Using the traditional operation mode, the labor intensity of the operators is high, the control o...
