Abstract

The invention provides a method for calculating tapping time of a steelmaking converter, which belongs to the field of ferrous metallurgy and comprises the following steps: determining a converter profile, a structural size, a converter tapping tilting mechanism type, working characteristics and a rotating speed range; calculating each inclination angle of the converter from tapping to ending, thevolume of molten steel and slag in the converter corresponding to each subdivided liquid level height, and the mass of the molten steel; calculating the corresponding tapping molten steel mass flow and outflow time further, and building a basic database; and in combination with a tilting operation system in the converter tapping process, calculating the tapping time. According to the invention, the influences of the irregular structural shape of the converter, the size of the tapping hole, the weight of molten steel and slag loaded in the converter, the tapping tilting angle, the tilting speed and other operation systems are fully considered. The method is reliable in theory, practical and accurate in calculation, and lays an important foundation for influence factor analysis of the tapping time of the converter, optimization of a tapping operation system, reduction of tapping temperature and other process optimization.

Description

technical field [0001] The invention belongs to the field of iron and steel metallurgy, and in particular relates to a method for calculating the tapping time of a steelmaking converter. Background technique [0002] From a material point of view, steel is still an irreplaceable material, but from a practical point of view, it needs green and sustainable development. Nowadays, the short-process process of iron and steel metallurgy has launched a strong impact and challenge on the traditional long-process production process with the characteristics of less energy consumption, energy saving, and high utilization rate of scrap steel. Although the short process has broad prospects for development and is a development direction and trend in the future, the long process is still the mainstream of my country's steelmaking process at present and for a long period of time that can be foreseen in the future. With the maturity of hot metal pretreatment and secondary refining process, ...
