Sarralle

Despite several operations can be performed through the slag door, the main application of the conventional slag door is the tapping of the slag by tilting the furnace. During EAF operations, unmelted scrap accumulates in the tunnel of the furnace wall from the furnace interior to the slag door opening, limiting the access for the sampling and injection equipment. Besides, the generated slag tends to freeze in large quantities. As a result, operators must regularly clean out this area by means of specific devices, such as oxygen lances, mechanical pushers etc, a technique that is highly dangerous for the operational personnel.

SARRALLE STEEL MELTING PLANT has developed a REMOTE CONTROLLED SLAG DOOR which provides EAF steel makers the following:
