Description
Technical field
The invention belongs to steel-making automatic control technology field, relate in particular to a kind of converter flux automatically adding device and adding method thereof.
Background technology
Because China's robotization steel-smelting technology is started late; Most of steel mill still rests on manual steel-making or semi-automatic steel-making state; Though the big steel mill of part has introduced external robotization steel-smelting technology; But since China appointed condition, starting material condition, production organization mode and abroad exist than big-difference, in implementation process, have model calculation incompatibility problem.The robotization steelmaking system of external exploitation generally be calculate earlier reinforced batch with reinforced opportunity, when Converter Oxigen Blowing begins, will feed in raw material batch, reinforced opportunity text be transferred to converter programmable logic controller (converter PLC) and carry out.Converter PLC tires out the Weighting and Controlling that per-cent carries out flux according to current oxygen in the oxygen blast process, carried out the adding control of flux again through operation screen by operator.
The shortcoming of this mode is:
1, when the beginning oxygen blast, generate flux and add scheme, the blowing action Once you begin can't be made amendment again.The whole desulfurization of the molten iron of developed country, molten iron composition are known before oxygen blast, and the molten iron of China is a partial desulfurization, and the partial molten iron composition just obtains after oxygen blast begins, so model can't adapt to the desulfurizing iron situation of China;
2, flux can only add two batches at most under the automatic mode, can't satisfy the multiple batches of reinforced requirement of China.Because external molten iron silicon content is lower and stable; And part steel mill also has three to take off (desulfurization, dephosphorization, desiliconization), and external active lime quality (CaO%＞92%) also is higher than the lime quality (CaO%＞82%) of China simultaneously, therefore; External flux add-on is more less than domestic flux add-on; Flux only add a collection of or two batches be enough abroad, and, need add three batches, four batches even many batches sometimes according to domestic present situation.Therefore, can't satisfy the multiple batches of reinforced requirement of China.
3, in man-machine interface, need the operator in time to click " a collection of reinforced affirmation " or " two batches of reinforced affirmations " button, in time starting outfit carry out weighing; Every next defective material all need be clicked once, in case when the operator does not have timely clicking operation button, then can affect best blanking opportunity adversely, is not real real-time control therefore.
4, according to external design, when the converter heat finished, it should be empty state that the flux of converter gathers bucket; And the smelting practical situation of China are when the heat of being everlasting finishes; Often gather in the bucket because equipment, operation, reasons such as starting material cause to gather has remaining flux in the bucket.And gather remaining flux is arranged in the bucket, when adopting robotization steel-making operation, because the robotization steelmaking system of introducing can not identify this part flux weight, it is wrong that the therefore actual flux weight that adds converter is calculated, thereby the computing of model also is wrong.
5, because external top and bottom combined blown converter is not carry out spattering slag, in converter, do not add flux even spatter slag yet.And the converter of China is to adopt slag splashing technology, and also in stove, adds flux sometimes and come working the slag.The robotization steelmaking system of introducing can't identify the flux quantity that in stove, adds when spattering slag separately, but adding flux weight is obscured mutually when adding flux with oxygen blast will spatter slag the time, causes the miscount of flux weight, causes the Model Calculation mistake.
