Hood Type Resistance Furnace
Hood type resistance furnace is a batch furnace – not continuous. The base stays put. The heating hood – the bell – moves up and down. You lower it over the workpieces. Heat comes from electric resistance elements.
Why do people like it? Good temperature uniformity, energy efficient, seals up tight. If you're doing bright annealing on coils or stacked metal products, this is a solid choice.
Danyang Dingfeng Industrial Furnace Co., Ltd. is one of the most reliable manufacturers and suppliers of hood type resistance furnace in China. If you're going to wholesale durable hood type resistance furnace made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Definition
Hood type resistance furnace is a batch furnace – not continuous. The base stays put. The heating hood – the bell – moves up and down. You lower it over the workpieces. Heat comes from electric resistance elements.
Why do people like it? Good temperature uniformity, energy efficient, seals up tight. If you're doing bright annealing on coils or stacked metal products, this is a solid choice.
Working Principle
sssssElectricity goes into the resistance elements. The hood type resistance furnace get hot. That heat warms up the chamber. The outer layer is a metal hood. Inside is insulation. The whole thing is enclosed, so heat doesn't leak out much.
Sensors watch the temperature. A control system adjusts the power automatically. Keeps the heat even across the load.
Features
- Even temperature. The bell shape plus internal circulation fans spreads the heat around. We hold within plus or minus 5°C. For annealing consistency, that's what you need.
- High thermal efficiency. The design is sealed tight. Heat doesn't escape. Electric heating responds fast. Saves power compared to some other designs.
- Seals tight for bright annealing. There's an inner cover that creates a sealed atmosphere chamber. You pump in protective gas – nitrogen or hydrogen – and the parts come out bright. No oxide. No scale.
- One hood, multiple bases. This is where you save money. You buy one heating hood and several bases. Load one base while the hood is on another. The hood keeps working while you get the next batch ready.
- Precise control. PID controllers and PLCs. You can run complex annealing curves and repeat them exactly every time.
- Safe. Interlocks, over-temperature protection, atmosphere monitoring. When you're running hydrogen, safety is not optional.
- Clean. All electric. No exhaust, no smoke, no combustion byproducts. The shop stays clean. No permits for a stack.
Applications
Cold rolling mills
Bright annealing of cold rolled steel coils, silicon steel, stainless steel strips. These customers care about surface quality.
Non-ferrous metal processing
Copper coils, brass strips, aluminum foil rolls, wire bundles.
Automotive and electronics
High quality automotive sheets, precision electronic components. Surface quality has to be perfect.
Fasteners and hardware
Screws, bolts, metal hardware. Annealing restores ductility after cold heading.
Precision casting and forging
Stress relieving and annealing.
Research and labs
Material testing and small batch experimental work.
