We make wide range of Roller Hearth Furnaces to suit different applications. They find extensive application in the manufacture of precision - drawn steel tubes for bright annealing , normalizing, tempering, spherodizing etc. They are also used for annealing tubes of nonferrous material like copper & cupronickel. Other applications include heat treatment of forgings, hardening and tempering of long products like tubes, bars etc.
We have been supplying Roller Hearth Furnaces in India for more than a decade now. They have found very high level of acceptance because of trouble free and easy operation, minimum maintenance and the processed material meeting the stipulated quality standards unfailingly.
Our Roller Hearth Furnaces have fully welded gas tight casing, highly effective roller end seals and multiple curtains at entry and exit ends, which make them quite adaptable for using special atmosphere to obtain bright finish of the products processed and ensure uniform properties of heat treated components.
The cooling sections of our furnace incorporate our very innovative, plug-in type, water cooled tube bundles instead of the usual, trouble- prone water jackets. The tube bundles cool most efficiently and are long lasting. They can be easily removed, reinserted, repaired and tested, making them far superior to water jackets.
We offer both electric as well as gas or oil fired radiant tubes for heating. Highly efficient single ended radiant tubes are offered as high end alternative to U or W type radiant tubes in case of oil or gas, and automatic ignition and sophisticated flame monitoring systems are included as standard accessories in all cases.
Our Roller Hearth Furnaces are offered with PC based Programmable Logic Control system, powerful SCADA based software and extensive instrumentation . These provide high level of automation, automatic selection of process cycles with ready recipes, extensive archiving. They also enable close monitoring of utility consumption, alarm situations and operational parameters on color screens. Further, auto-ignition and flame monitoring can be affected directly from the control desk.
We have made Roller Hearth Furnaces of special design too, for example, with inlet and outlet vacuum vestibules for cleaning the inside of the refrigeration grade copper tubes, with jet cooling section with external by-pass cooling for faster cooling, for hardening long, alloy steel bars, with oscillating hearth and quick quenching facility etc.
