We cater to the requirements of our clients and offer quality range of billet homogenizing furnaces that is available in various configurations. With our advance technology, we can custom-built furnaces to suit required production rates, the shop space available and type of product being processed. These furnaces comprise highly efficient, powerful air re-circulation and heated systems using gas, oil or electrical elements. Our clients can also avail from us load build systems with spacer magazine storage, which can be either semiautomatic or fully automatic.

Features:

• Multiple control zones

• Movable furnaces for heavy jobs

• Invertors control of fans to enable reversing air flow and uniform heating

• Automated load mechanical handling gear

• Forced air cooling chambers with optional water quench

• Automated contact thermocouple probes to measure actual billet temperature in side furnace chamber

• Integrated internal forced cooling air systems to control cool billets

• Specialized PC, PLC based control systems with human/machine interface giving `Set point control

• SCADA control systems

With substantial industrial experience, we have emerged as one of the prominent manufacturers of bogie hearth furnaces with air circulation. Available in compact structure, these furnaces are used for heat treatment applications such as annealing, ageing, or soft annealing that requires high temperature uniformity and optimum charging ability for heavy charge weights. The furnaces are available with powerful fans that ensure optimal air circulation.

Features:

• Maximum temperatures of 650° C or 850° C

• Bogie on rails

• Heating options

• Electrically, gas or oil fired heating

• Optimum temperature uniformity

• Powerful fan with vertical air circulation

• Over-temperature limit controller with adjustable cutout temperature for thermal protection class in accordance

Along with our range, we also provide additional equipment such as:

• Electro-hydraulic vertical lift-door

• Horizontal air circulation for optimal temperature throughout the useful height

• Electrical bogie drive

• Fan system for faster cooling

• Powerful direct gas heating

• Fixed hearth and movable furnace for heavy jobs

• Automatic control of exhaust air vents for optimal cooling of the furnace chamber

• Optimal temperature uniformity with multiple zones of control

• Support structure made from heat resisting cast alloy steel for high charge weights

• Process and charge documentation via SCADA software or PLC-based control system

• Heat-resistant boxes for protective gas furnace or carburization processes

We are one of the reputed manufacturers and exporters of heavy-duty box furnaces that are designed for an intensive and continuous use up to a max temperature of 1250⁰C. Equipped with a ramp to set point digital indicating controller, accurate and desired temperatures can be safely maintained in the furnaces. These are insulated with high quality refractory bricks to minimize the heat up and cool down times. The temperature control accuracy and the quality of the insulation ensure maximum performance and efficiency of furnace. Our heavy-duty furnaces are known for easy operation and long service life. We also have the ability to customize our heavy-duty furnaces as per the required process specifications.

Features:

• High quality insulating brick backed with hi-density fiberboards

• Auto tuning digital set point temperature controller

• Heavily hinged 1800 opening door, lift up

• Maximum temperature of 1250⁰C

• Fast heat up rate and recovery time

• Factory wired, assembled and tested for simple set-up and operation

• Hi-limit overshoot protection

• Heavy-duty firebrick hearth with removable hearth plates

• No operation noise

• Automatic door switch to turn off the fans or heat when door is open

• Long-lasting and efficient, these can be used in a variety of processes

Our clients can avail from us stress-relieving furnaces that have gained appreciation for international quality standards. These furnaces are ideal for heat treatment like stress relieving, post welding, annealing, hardening, normalizing, tempering, homogenizing and quenching of various cast, forged, or fabricated components, parts or pressure vessels in different weights and sizes. Lined with refractory bricks, ceramic fiber blankets or modules, these furnaces are available in electric heating, oil/gas or dual firing system.

Salient Features:

• Heat recovery recuperator

• Motorized door or bogie movement

• PID or Programmable controllers

For post-weld heat treatment (PWHT), we have successfully fabricated an extra-large 9 m high x 9 m wide x 32 m long heat treatment furnace. It is a perfect option for treating all types of vessels in one piece, thus solving the problems of treating the vessel as several pieces.

Features:

• As per the type of steel, normalizing and tempering heat treatment is performed after welding or hot forming to improve strength and toughness

• Even Pre-heating for welding on various material such as pipe work, high pressure parts, test pieces, can be carried out

• Equipped with PID, PLC for an automatic programmer which are intern connected to profile control software & continuous chart recorders control

Applications:

• Stress relieving

• Preheat

• Post weld heat treatment

• Annealing

• Gas combustion firing
