Ageing Cum Annealing Furnace for Aluminium

The annealing furnaces are lined with a combination of ceramic fibre board backed-up by ceramic fibre blankets of suitable grade with stainless steel studs for side wall, roof and doors to minimize the skin temperature.
For electrically heated furnace, the process control shall be based on heat head ratio control philosophy with thyristor heater controllers for better temperature control and energy efficiency. Their electrically heated furnaces can be offered with 100% thyristor controllers or 30% thyristor with 70% STAR-OFF mode for better energy efficiency during heating & soaking.

As an alternate to fuel fired heating system, the furnaces are fired with high efficiency burners supported by a full complement of combustion system consisting of combustion fan, atomizing fan, oil heating and pumping systems and/or gas trains. In addition auto ignition, flame failure safety and complete control systems are offered. Practically any type of liquid or gaseous fuel can be used viz. Light Diesel Oil, LPG, Natural Gas singly or a combination of any oil or gas in case of dual fired furnaces.
