Continuous Furnace Hybrid Type_DOWA Thermotech

DOWA Thermotech's Continuous Furnace Hybrid Type is a world-standard continuous gas carburizing furnace designed for high efficiency and low cost. This innovative system integrates a tray pusher mechanism with a roller hearth system, further incorporating high-performance regenerative gas burners in the heating zone to optimize energy usage. This hybrid approach results in significant operational advantages, including an approximate 40% reduction in energy costs, a 30% decrease in CO2 emissions per unit weight, a 10% shorter lead time within the furnace, and a 20% reduction in installation space compared to conventional models. Structurally, the furnace utilizes refractory bricks or ceramics for insulation and offers flexibility with both electric and gas heating methods. Material handling is precisely managed by a pusher system in the initial heating section, transitioning to a roller hearth system for subsequent critical processes such as carburizing/diffusion and multiple quenching stages, including an oil tank. This advanced design makes it an ideal solution for demanding heat treatment applications requiring precise surface hardening with enhanced environmental performance and reduced operational footprint.
