Vacuum Heat Treatment

LVH has world class vacuum furnaces of "versa treat" brand with latest technology from its own group LVT. Mainly concentrating to ensure consistent metallurgical results as per standards which in turn results in multi fold life of heat treated products. LVH production centres are spread across the country in order to serve the customers at their door step.

LVH has well designed systems & components as in very good pumping stations, optimized heat exchangers including the quintessential quenching fan and the optimized heating chambers.

A specific characteristic of the heating system is its optimized measuring and control system. It ensures a uniform heat transmission to the work piece and into the heating chamber and thus prevents the development of undesired heat stress.

A complete documentation of the whole charge cycle is guaranteed by means of the hardware and software implemented in our systems.

The cooling system is designed to obtain optimum cooling. This system makes it possible to obtain the optimum microstructure apart from required hardness throughout the cross section in various air harden able steels as well as in various intricate shapes and large-sized components to obtain the desired metallurgical properties.

With very high cooling rate at gas pressure values up to 6 bar abs. and maximum gas flow within the system ensures that uniform cooling throughout the job is obtained.
