The invention provides a main channel residual iron slag content control and main channel residual iron discharge process, and relates to the technical field of blast furnace front. According to the main runner residual iron slag content control and main runner residual iron discharge process, an effect of completely discharging the residual slag in a main runner can be basically achieved, a purpose that the residual iron in the main runner does not carry the slag is achieved, and the phenomena of incrustation and cap hitting caused by the fact that the slag-containing residual iron is put into an iron ladle are avoided; and knocking safety accidents caused by the fact that the molten iron flows out of a slag runner and is in direct contact with slag flushing water in the extrusion processcan be effectively avoided. 本申请提供一种主沟残铁含渣量控制及排放主沟残铁工艺，涉及高炉炉前技术领域。通过本申请提供的主沟残铁含渣量控制及排放主沟残铁工艺，可基本达到完全排除主沟内残留炉渣的效果，实现了主沟残铁不带渣的目的，避免含渣残铁放入铁包引起的结盖、打盖现象，同时凹槽的设置，也可有效避免了挤压过程中铁水流出下渣沟，直接和冲渣水接触导致的爆震安全事故的发生。
