China Rainbow Energy-Saving Continuous Mesh Belt Quenching Furnace Automatic Heat Treatment Line manufacturer

Rainbow Energy-Saving Continuous Mesh Belt Quenching Furnace Automatic Heat Treatment Line

Product Overview

Our continuous mesh belt quenching furnace is a professional industrial heat treatment solution specially developed for mass production of fasteners and metal hardware. It is widely matched with cold heading machines and thread rolling machines to form a complete fastener production line, realizing continuous automated quenching, tempering and cooling processes, which greatly improves production efficiency and ensures stable and consistent mechanical properties of finished products.

Core Features & Advantages
  1. Precise & Uniform Temperature Control The furnace adopts multi-zone independent PID temperature control system with high-sensitivity thermocouples, which ensures uniform temperature distribution in the furnace chamber, effectively reduces workpiece deformation and unqualified rate, and guarantees stable hardness and strength of batch products.
  2. High Energy Efficiency & Low Consumption Lined with high-density aluminum silicate fiber insulation layer, the furnace has excellent heat preservation performance, which reduces heat loss by more than 20% compared with traditional brick furnaces, effectively lowering long-term operation cost.
  3. Fully Automatic Intelligent Operation Equipped with PLC control system and touch screen human-machine interface, parameters such as heating temperature, mesh belt running speed and production rhythm can be preset, monitored and adjusted in real time. The equipment can run continuously for 24 hours with less manual intervention.
  4. Optimized Workpiece Quality Protective atmosphere system is optional, which can effectively reduce surface oxidation and decarburization of workpieces during heat treatment, improve the surface quality of finished products, and reduce the workload of subsequent finishing processes.
Application Fields

It is suitable for heat treatment processes such as quenching, tempering, normalizing and stress relief of various carbon steel, alloy steel and stainless steel standard parts, fasteners, hardware accessories, small auto parts and electronic stamping parts.
