[0031] Specifically, the working process or working principle of the slag blocking device for an industrial furnace is as follows: in the specific slag blocking of an industrial furnace, a common device can block the residue, but if a large volume of residue appears, it will not only jam the blocking port, but also cause certain wear to the slag remover.

When the crushing is completed, the operator can open the slag baffle 23 and then use the collection box 22 to collect it, so that the larger residue can be crushed and then discharged without getting stuck at the slag discharge port 25 and causing wear to the slag remover. When the operator needs to protect the interior of the shell 12, the operator can install three protective plates 21 on the inner cavities on both sides and the rear inner cavity respectively, so as to protect the interior of the shell 12. By setting the protective plate 21 to a ceramic material that is resistant to high temperature and corrosion, it can avoid erosion by the residue and protect the components in the furnace. It can be used to prevent the waste slag from directly contacting the furnace wall or other furnace components, thereby improving the protective measures inside the shell 12 and facilitating the operator to use it. At this point, all processes are completed.
