Hi Shipto, have you any pics? are you using solid cooker type elements or wire wound fire type. I have seen small kilns and alloy melters with both. With the cooker ring type element, they are underneath the crucible set into a fireclak moulding so that the crucible sits on the moulding, not the element. With the wire coils, they are fitted in slots in the side walls of the furnace, set back into the refractory and sometimes have refractory pencil made from porcelain or similar inside the coil to support the elements, and prevent them sagging out of the slots when they are hot, any help?
