Product Details

SUS 304 201 stainless steel sink continuous atmosphere protective bright annealing furnace

* Brief Induction:

This steel belt continuous gas shielded heat treatment furnace is mainly used for the continuous bright quenching of Martensitic stainless steel, bright annealing of austenitic stainless steel s. After suffering from such equipment treatment, product surface becomes bright without oxidation. The furnace boasts stylish design, rational structure, energy saving, high heat efficiency, stable production quality, safe and easy use, not generating industrial pollution. Advanced temperature control manners: Intelligent thermostat, silicon controlled rectifier and Schneider electrical switches ensure temperature control precision of ±1℃. It’s advanced, reliable, practicable and cost effective as an industrial furnace.

This device is mainly composed of transmission system, heating system, cooling system, control system, and ammonia decomposition gas supply system. The muffle furnace is made of imported high-temperature resistance nickel alloy(310S) by pressing welding; dismountable electric heating elements can upper-lower heat; steel belt conveying is stepless speed regulating; the gas mixture (hydrogen 75% and nitrogen 25%) decomposed from liquid ammonia gets into the hearth and reaches gas protection effect; the gas direction regulating device ensure stable atmosphere. Having treated by this kind of furnace, product surface will become bright and won’t be oxidized. All treated products will reach excellent consistency.

Ø Add two pieces soft flange on the between preheating zone, heating and cooling zone, to make muffle in high temperature continuous work with sufficient space expansion and twisted, and the muffle bottom cannot concave-convex wave ,arch and bending. Keep the steel belt( mesh belt) contact the bottom of the furnace to improve the muffle and steel belt (mesh belt ) working life.

Ø With reasonable structure of heating, uniform furnace temperature, workpiece on the conveyor belt running smoothly, little deformation. Furnace hearth size can be according to customer's different size of the product and production design and manufacturing, with a strong specificity and generality.

Ø Channel furnace overall appearance is "bridge" structure, front-back inlet and outlet chamber using high quality materials into intermediate sandwich pipe body; The front and back working face with horizontal line to be a certain angle, the angle design is 9 °. Its advantages: to saving protective atmosphere consumption, reduce the production cost.

Ø Adopts advanced frequency control of motor speed conveyor belt control system, realize the stepless variable speed drive of components, precisely control the workpiece in the running time of the heating zoen, ensure the bright annealing heating curve accurate implementation.

Ø Equipped with modern energy-saving type ammonia decomposition furnace

* The advantages of this type furnace compare with vacuum bright annealing

furnace :

Ø Not only low cost, but also can testing the quality of the products and change the production process at any time.

Ø Continuous furnace annealing treatment time is short, high production efficiency, stable production process.

Ø And a high degree of automation, easy operation and operation technique and also do not have a vacuum furnace is complex and high requirements, etc.

* Technical Parameter：

* Application:

1.Mainly be used for steel belt, steel cutting tools, small mechanical parts without oxidation under the high temperature heating and cooling without oxidation. Such as ,SUS420J2,3Cr13,410,301,304,316,3156L,420,S315,201,202,etc.

2.Can also be used in powder metallurgy sintering, annealing of magnetic materials and some small metal parts, such as watch case, strap, kitchenware industry of annealing, quenching and stainless steel bright annealing, especially Cr13 stainless steel quenching, stainless steel solid solution treatment, etc.

3.Suitable for stainless steel, carbon steel, copper, brass, aluminum same base metal or different base metal brazing, can be widely used in compressor industry machine, household appliances, cookers, hardware and other industries.
