·RGB series roller-hearth thermal treatment production line is composed of several sets of equal-interval driving rollers which transport the working pieces. It is to perform all linkage procedures, applicable to polishing, quenching and tempering of medium & large components.

·Work pieces of RGB series roller-hearth thermal treatment production line are driven stably with few collsional damages. Our company's patented quench slot with vertical-swinging mechanism and low-deformation technology can effectively cut down the quench deformation and reach the top level in this sector.

·Low-power close-packed radiant tubes for heating are adopted to make furnace temperature even. The temperature control system employs a modularized non-contact and non-surge SCR control technology to realize a steady heating and a high precision of temperature control.

·The production line is equipped with perfect interlock protections and the optical alarm function.

·Temperature-control, electricity-control and atmosphere-control all adopt computer technology.
