Product Introduction
The Juyi Industrial Tunnel Furnace is specifically designed for bright annealing, solution treatment, and weld stabilization of various metals and stamped parts. Featuring stable heating and advanced gas protection, this tunnel furnace ensures high-quality surface finish and metallurgical properties suitable for jewelry and metalworking industries.

Working Principle
The machine uses a continuous conveyor belt system to transport metal parts through a controlled heating chamber. The furnace heats the components to temperatures up to 950℃ within an ammonia gas atmosphere, preventing oxidation and ensuring surface integrity. Water-cooling technology efficiently regulates the furnace’s temperature and prolongs equipment lifespan. The treated parts undergo bright annealing, solution treatment, or weld stabilization as they pass through the heating zone uniformly.
Key Advantages
• Stable and Uniform Heating — Ensures consistent temperature throughout the heating zone for even treatment.
• Gas Protection with Ammonia Atmosphere — Prevents oxidation and discoloration, maintaining metal brightness.
• Water Cooling System — Efficient temperature regulation enhances equipment durability and operational safety.
• Easy Loading and Unloading — Conveyor and compact design facilitate smooth material handling and increased productivity.
• Compact Footprint — Optimized size fits easily in industrial workshops without occupying excessive space.
Applications
• Jewelry Manufacturing: Bright annealing and solution treatment of precious metals and alloys.
• Metalworking Industry: Heat treatment of stamped metal parts, including weld stabilization and surface enhancement.
• Precision Components: Suitable for aerospace, automotive, and electronics parts requiring controlled heat treatment.
