No. of patent: ZL69222909.1
1.Special furnace model design, compound type chamber wall, high efficient burner , heat exchanger and the heating mode with direct fire make thermal efficiency improve nearly one times than traditional steel wire heating treatment, target of energy loss reaching international advanced level.
2. Exact temperature controlling , furnace inner atmosphere controlling and high value of DV operating make loss rate of oxidized to reduce to 40?
3. Special blocking design of oil feeding and control manner of delivery pump (No. of patent, ZL96222909.1), make the error of furnace temperature control extremely minimal.
4. Novel setting, control and display of temperature, air-fuel ratio (a modulus), makes computer control system operated easily.
5. Do not produce black smoke and pollution to environment.
6. Special furnace frame makes working life longer, minor repair cycle for 3 years and 10 years of heavy repair cycle.
