| description | The invention relates to a blast furnace tapping sulfur distribution coefficient adjusting method and a sulfur distribution coefficient adjusting system. The blast furnace tapping sulfur distribution coefficient adjusting method comprises the following steps: step S10, detecting the sulfur content in molten iron and iron slag separated by a skimmer in a blast furnace iron runner; step S20, calculating a blast furnace tapping iron-sulfur distribution coefficient Ls; and S30, when Ls is larger than 100, the width of an outlet of the slag skimmer is increased, and when Ls is smaller than 80, coke powder is added to the end, close to an iron outlet, of the iron runner, and the blast furnace tapping iron sulfur distribution coefficient Ls is kept between 80 and 100. Compared with a mode of adjusting the raw material ratio, the mode has the characteristic of high real-time performance, at least one smelting period does not need to be waited, adjustment can be directly carried out according to the sulfur content det |
