I would be great if someone could correct my English. The context is, I wan to explain the advantage of the Open Well type melting furnace. ================================================ There are some advantages in this Open Well type furnace. First, the recovery rate of the metal will be improved. Since this furnace enables to do “ immersion melting”, recovery rate is better than that of conventional furnace. Secondly, in terms of efficiency in operation, it’s also good. Because this you can keep burning while feeding scraps into the furnace. So you don’ t have to stop operation while feeding and therefore, production time can be reduced.
