Converter oxygen gun/charging/temperature institution comprehensive simplified model system and operation method

Abstract

The invention relates to a converter oxygen gun / charging / temperature institution comprehensive simplified model system and an operation method. The operation method comprises the following steps: according to each chemical element, a temperature and a molten iron quantity of molten iron conditions, a waste steel number and influence of each external condition on the temperature, a target oxygen and tapping temperature is set according to a steel type terminal point, and various material quantities are predicted, calculated and added; when the predicted temperature is badly insufficient to influence the tapping temperature safety, the blowing flow and the waste steel are reduced for making up according to a difference between the predicted terminal temperature and a theoretic tapping temperature; and gun positions of oxygen guns are respectively calculated according to different slagging modes. The operation method is developed according to actual parameters of a converter technological process, is suitable for scene demands, is higher in practicability, is high in intelligent comprehensive degree, relieves the working burden of operators, and reduces quality accidents caused by manual calculation errors.

Description

technical field [0001] The invention relates to a steel plant converter operation technology, in particular to a converter oxygen lance / feeding / temperature system comprehensive simplified model system and operation method. Background technique [0002] Traditional converter steelmaking generally relies too much on the experienced operation of steelmakers. The operation control in terms of composition, temperature, and furnace conditions is not fully standardized. The hit rate is low, the composition and temperature fluctuate greatly, and there are many abnormal furnaces, resulting in the loss of furnace conditions; adding materials, carburizing, alloying, etc. are still performed manually, with low efficiency, high risk of accidents, and high labor intensity for workers , the system is less enforceable. Contents of the invention [0003] In view of the fact that in the prior art, the addition of materials, carburization, and alloying to the converter in steel mills is sti...
