Continuous gas shielded bright heat treatment electric furnace
Used for continuous production of martensitic stainless steel through bright quenching, austenitic stainless steel through bright annealing (solid solution) treatment, various copper materials and copper alloys through intermediate recrystallization annealing, final annealing, and stress relief treatment. The furnace design is innovative, the structure is reasonable, energy-saving and high thermal efficiency, the production quality is stable, and the use is safe and convenient. Easy to operate, no industrial pollution. The temperature control method is advanced, using intelligent temperature control instruments, intelligent thyristors, and Schneider electrical switches. Control accuracy ± 1 ° C. It is progressiveness, reliable, practical and economical in industrial furnaces. This equipment consists of transmission system, heating system, cooling system, control system, and ammonia decomposition gas supply system. The muffle furnace liner is made of imported high-temperature resistant nickel alloy material, which is pressed and welded together; Detachable electric heating element for up and down heating; The steel belt conveyor has stepless speed regulation, and the mixed gas of liquid ammonia decomposition (hydrogen 75%, nitrogen 25%) enters the furnace to achieve gas protection effect. The gas direction adjustment device ensures stable atmosphere. After heat treatment by the equipment, the surface of the product is bright and free of oxidation, and the consistency of the treated product is good.
This furnace type uses heat-resistant stainless steel belts or heat-resistant stainless steel mesh belts to transport workpieces that require heat treatment, through the heating furnace and cooling zone. Introduce inert gas or ammonia decomposition gas into the furnace as a protective atmosphere to prevent and avoid oxidation of the workpiece during heating and cooling processes. So as to ensure that the surface of the stainless steel workpiece is bright, free of oxidation and scratches.
The heating furnace (also known as the furnace liner or muffle tube) is made of high-temperature resistant nickel alloy to ensure that the workpiece is cooled to the required process temperature when it is taken out of the furnace.
The continuous gas shielded bright annealing furnace adopts a reasonable heating structure, with uniform furnace temperature, smooth operation of workpieces on the conveyor belt, and minimal deformation. The furnace size can be designed and manufactured according to the specifications and production volume of different products for users, with strong specificity and universality.
The biggest advantage of this furnace type
Widely applicable, suitable for continuous production such as bright quenching, bright annealing (solid solution) treatment of stainless steel, intermediate recrystallization annealing, final annealing, and stress relief treatment of various copper materials and copper alloys. Equipped with a strip winding mechanism, it is suitable for bright annealing treatment in the cold rolling and stretching industry of metal strips.
Advantages of this furnace type compared to vacuum furnace brazing
Not only is the cost low, but without vacuum furnace brazing, product quality cannot be monitored at any time, and defects in the production process cannot be changed. In addition, the operation technology and process are not as complex and demanding as vacuum furnaces, making it easy to operate and highly automated.
