Whole-course capping process for hot-metal bottle

The invention relates to the field of industrial manufacturing, and discloses a whole-course capping process for a hot-metal bottle, which comprises the following steps of: 1, designing a reasonable hot-metal bottle cover according to the shape of a bottle opening of the hot-metal bottle and an iron adding mode, and ensuring that the hot-metal bottle pours iron smoothly and does not spill iron; 2, combining blast furnace tapping position layout, molten iron tank height, tapping direction and iron adding direction to design a reasonable covering and uncovering mechanism, and ensuring that covering and uncovering are smooth, stable and reliable before and after blast furnace tapping; thirdly, a blast furnace tapping position covering and uncovering mechanism has a reliable emergency treatment function, and ironmaking production is prevented from being affected; and fourthly, besides blast furnace tapping, molten iron transportation, hoisting and iron mixing are all carried out with a cover, the opening time of
