WESMAN UTTIS ROTARY HEARTH FURNACES
WESMAN UTTIS Rotary Hearth Furnaces type CR are manufactured on the basis of designs and drawings of our collaborator UTTIS Industries, Romania and are used for small batches or individual parts. Our furnaces are designed for greater uptime, ease of maintenance, trouble free operation and can also be customized to meet your exact heat treatment and processing requirements. These furnaces which operate under atmosphere are mostly used in India for reheating or reaustenizing of the carburized components to hardening temperature before press quenching but can also be used for other applications as well. * See under Application Heading.
APPLICATION
The Rotary Hearth Furnaces are extremely versatile and its high throughput and repeatability of results make it particularly suitable for heat treating large quantities of the same parts and can be operated as a standalone unit or can also be interlinked with other plant components.
The Rotary Hearth Furnaces are used for various treatment processes such as case hardening and carburizing (low case depth), neutral hardening, reheating, tempering carbonitriding (low case depth), annealing etc.
The types of products which can be processed are quite varied being Automotive Components, Bearing Components, Forgings, Off Road/Agricultural components, Powdered Metal components and Aerospace components.
