Gas Protection Annealing Furnace
Gas protection annealing furnace. You use it to get rid of internal stress and fix the metal's internal structure. Heat it up, cool it slow. That makes the metal stronger and easier to machine.
Compared to other annealing equipment, this one lets you control what's inside the furnace. No oxygen means no scale on the surface. No decarburization either.
Danyang Dingfeng Industrial Furnace Co., Ltd. is one of the most reliable manufacturers and suppliers of gas protection annealing furnace in China. If you're going to wholesale durable gas protection annealing furnace made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
Product Definition
Gas protection annealing furnace. You use it to get rid of internal stress and fix the metal's internal structure. Heat it up, cool it slow. That makes the metal stronger and easier to machine.
Compared to other annealing equipment, this one lets you control what's inside the furnace. No oxygen means no scale on the surface. No decarburization either.
Working Principle
Simple idea. You pump protective gas into the furnace to push the air out. That gives you an inert or reducing atmosphere. The metal doesn't react with oxygen at high temperatures.
What gas do you use? Nitrogen, hydrogen, argon, or a mix. Depends on the material and what you're trying to accomplish.
You keep the gas flowing through a sealed chamber. That takes out oxygen and moisture. The workpieces never see air. Less scale, less decarburization. Better surface, more stable results.
Features
Bright surface. The protective gas does its job. Parts come out clean. No pickling, no shot blasting afterward.
No decarburization. The atmosphere stays controlled. Carbon steel and tool steel keep their surface hardness.
Gas choice is flexible. Nitrogen, hydrogen, argon, endothermic gas – pick what your alloy needs.
Better properties. The microstructure gets refined and uniform. Internal stress goes away. Surface and composition stay intact.
Clean operation. Compared to salt baths or open flame, this furnace makes less mess. The shop stays cleaner.
Automated. Flow meters, oxygen analyzers, PLC controls. The system runs itself. Atmosphere stays stable from start to finish.
Saves energy. Sealed furnace, no heat leaks. Circulating gas improves heat transfer.
Applications
The Gas protection annealing furnace is widely used in many fields,including:
- Steel, non-ferrous metals, alloys, even electronic components.
- For steel: internal stress goes away, toughness and ductility improve, surface stays smooth. Machining gets easier. Stainless and high alloys – they oxidize and decarb at high temperatures. This furnace stops that.
- Also works for copper and aluminum alloys. Improves conductivity and mechanical strength.
- Even semiconductor materials. Optimizes crystal quality. Electronic components get more stable and reliable.
