The use of lead smelting cupola will always stop for maintenance and rest. Generally, the use of lead smelting cupola is always in operation, and there are many details to deal with after the operation.
If it is planned to shut down the furnace, that is to carry out maintenance, clean up all the materials in the furnace, build the furnace body, run for a long time, some of the furnace will have agglomerates, shut down thoroughly clean, shut down the water supply, open the vent valve, close the inlet valve, wait for the furnace temperature to reduce, and then remove the sinter.
In case of temporary shutdown, it is certain to stop feeding and try to reduce the charge level. Stop the water supply, open the vent valve and close the inlet valve, which is the same operation as the usual planned shutdown. The difference is that we can insert a steel drill into the throat and seal it with yellow mud, and the siphon port is insulated with firewood. It can also be used as usual when waiting for the furnace to start again.
There is also a case of failure shutdown of cupola in lead smelting. In fact, this shutdown is similar to temporary shutdown. You can refer to the above shutdown mode, but the maintenance steps are added.
