SECO/WARWICK has recently commissioned a 3.96 ton per hour capacity Walking Beam Furnace at NHK Springs India Ltd., Andhra Pradesh, India.
Sławomir Woźniak, Executive Director (Asia) at SECO/WARWICK commented, „Thanks to this tailor-made solution, NHK Springs can achieve higher productivity with lower cycle time, better quality and minimum rejections with the ejector mechanism. We are pleased to work with NHK Springs to develop a solution that best suits the application and customer expectations.”
NHK Spring India Ltd. is a manufacturer of Automotive Suspension Components for passenger cars, commercial vehicles and utility vehicles that will use this solution for mass production. Walking Beam Systems made by SECO/WARWICK for spring applications are best suited to the automotive and railway industries.
Mr. Manoj Gupta, DGM (Projects), NHK Springs India Ltd. added „We are pleased to partner with SECO/WARWICK whose expertise in both emerging technologies as well as their reputation for reliable standard solutions enable NHK Spring to deliver the best products to our customers. The Walking Beam Furnace supplied by SECO/WARWICK is technologically advanced with a specially designed ejector mechanism for better quality end products. The SECO/WARWICK team also provides technical and service support that we demand to keep our operation running smoothly.”
The SECO/WARWICK Walking Beam System solution is custom designed for the heat treatment of leaf springs especially with eyes on end (parabolic and berlin). Leaves are passed through the furnace by means of the walking beam mechanism, which is custom-designed for a low cycle time of 9 seconds. Leaves are discharged through drop-down ejector instead of the conventional type of rollers. This mechanism has an advantage over rollers as leaf traveling through rollers with eyes on the end, movement during travel, sometimes damaging eyes that are stuck on the discharge end.
The drop-down ejector mechanism has an added advantage over rollers where during discharge leaves are placed on the scissor lifts and then to the conveyor for further process.
SECO/WARICK’s Walking Beam System solution is equipped with dual – fired burners, automatic ignition system, flame monitoring system, furnace pressure monitoring system, highly equipped gas train system with mass flow meter, oil pumping system and hydraulic systems. The dual-fuel system will enable NHK to stay in continuous production in case of short supply/unavailability of anyone fuel with minimum switchover time. The furnace operation is controlled by PLC except loading of leaf on charging end. This ensures auto control and close monitoring of system parameters which in turn assures a better quality of processed materials. Unique furnace design and temperature control systems results in fast heating rates with close temperature uniformity within the load.
India’s manufacturers of automotive suspension components for passenger and commercial vehicles are required to meet the requirements of today’s demanding market. SECO/WARWICK’s proven expertise including furnaces and equipment, both standard and customized state-of-the-art heat processing technologies along with their innovative approach to business, make SECO/WARWICK a partner of choice in the most demand industries. SECO/WARWICK offers heat treatment solutions that provide compliance with the essential requirements. Their highest standard of quality for both equipment and services is appreciated by more and more Indian entrepreneurs.
