An electrical furnace Firing the ceramic products has been designed and its automatic control has been implemented. Furnace (100x50x50 cm) may be used to fire even small ceramic products such as trinkets. PLC has been used for the automation of the system. The heat from the furnace has been measured by means of thermocouples and has been transferred to the PLC by analog module and the heat of furnace has been controlled according to the obtained heat values. Besides, required heat degree and the heat in the furnace have been traced on the screen of the control Panel. The sample products fired in the furnace Proved that the system operated successfully without problem.
