The furnace chamber will be lined with Imported Ceramic Boards of 1700°C This will follow by a layer of Vacuum Forming zirconia BOARDS of 1500°C. Low mass high grade thermal insulation will be provided to ensure consistent result in efficient heating and cooling of the furnace and to keep the surface temperature within permissible limits. Double walled door with insulation by Ceramic Boards / zirconia Fibre Boards is provided in the front opening. The door will be mounted on heavy duty hinges to provide perfect seal when the door is in closed position. The Door will have simple but effective locking arrangement. As Option a door switch is incorporated, to cut off the power supply, when the door is opened during the operation and to re-start again when it is closed. The temperature inside the chamber is indicated and controlled by a smart range Digital PID Programmable Controller which will have Auto/Manual Control Features and Other standard control systems. The Controller work in conjunction with B Type thermocouple and thyristor power control device. Due to this arrangement of current Limit Feed Back Arrangement, the control system is protected from higher current/voltage. A compact control panel accommodating the following will be provided aling with the furnace: Microprocessor based Programmable PID controller.(Make – Honeywell or Shinko Or Eurotherm)
