Construction and Specification for Galvanizing Bath Furnace
APPLICATION : This is designed for galvanizing of Cable trays, MS structural, Poles and
other miscellaneous items by Hot dipping in the zinc molten bath at 450 to 455 deg C.
The general arrangement of galvanizing bath furnace shall be as illustrated in our enclosed drawing.
The galvanized bath furnace offered is a Diesel / Gas fired with Steel kettle of special
material used for melting of zinc and designed for continuous operation.
The galvanizing bath furnace shall have a Kettle of size of 12,000 mm long x 1,500 mm
width x 2,000 mm Deep.The Kettle is installed inside the pit suitably thereby
bringing the operating level at about 750 mm from floor level.
The furnace will be of indirect heating type with suitable chamber, burners and Blowers. Inspection pockets provided for inspecting the furnace chamber and kettle wall. Zinc drain pocket for drainage of molten zinc in event of kettle puncture. Burners will be suitable for Diesel or Gas.
For controlling the temperature of molten bath we include an automatic temperature control system comprising of a digital temperature controller, thermocouple sensor and solenoid oil valves.
The burners will automatically go fast and slow during the process whenever temp goes down, it will go fast and when temp goes high, it will slow as per the set off temperature. Due to this the consumption of fuel will be minimized.
The Furnace consist of a refractory brick lined work using high quality alumina bricks.
The galvanizing bath furnace is arranged for firing with 4 Nos. reputed make oil/gas fired burners with supporting Blowers, Control Valves etc.
Electrical Control panel is supplied incorporating digital temperature controller and various electrical switchgear and is completely wired from inside and ready for connection to the mains.
The galvanizing bath is capable of giving an out put of 50 – 60 tons/day. However the
actual out put would vary considerably with the size, shape and weight of the steel
structure and parts to be galvanized.
