Two types of wall blocks are installed on the floor of Patil, and one of these wall blocks is called Patil molten outlet wall block.

When the melt is transferred from the pot to the tundish container, it exits from a hole that is lined with the outlet wall blocks of the pot. The application of the well block of the melt outlet of the bottle is to maintain the internal nozzle of the bottle.In the bottom of the pot, in addition to the melt outlet blocks of the pot, there are other blocks called the gas blow well block, the process plug well block, or the housing block.

The task of gas valve wellblock is to protect and maintain Prosplug. In order to remove the molten impurities from the bottle, a Prosplug is installed in the bottom of the bottle. Gas is blown into the melt through the Prosplug and causes the melt to be purified.

Prussian plugs have small holes that cannot be seen with the eye, and argon gas is blown from inside the holes, which causes the melt to rotate and move and tumbling. As a result of this rotation, the impurities move and collect as slag on the molten surface. The slag is removed from the molten surface and enters another container, and after purification or alloying in the crucible, it is transferred to the CCM casting line.
