Shaft furnace and its features

• Temperature control: high precision control of temperature changes, automatic process of heat treatment. The fan is mounted in the bottom of the furnace to ensure stable heat throughout the entire cooking process and maintain a uniform temperature, temperature accuracy is ± 5 degrees Celsius.
• Source of heating: Electricity.;
• Protective atmosphere: ammonia or purified nitrogen protect steel from oxidation, decarbonization, preventing metal loss ;
• Capacity: 8 ~ 36 tons, takes small wire parties (≤ 10 t / party);
• Easy to use and install: the cover of the furnace is equipped with a pneumatic device for opening and closing.

Practical use:

heat treatment, the total treatment of the wire, aluminum alloy, spherical wire, light wire and etc.

Specifications

PIT-TYPE ANNEALING FURNACE

Pit-type annealing furnace has a cylindrical housing welded with angle steel and steel plate. Inside housing, the pit-type furnace is made of light fire bricks. After work pieces that are to be heated are put into charging basket, they will be sent in or taken out through workshop hoisting equipment. Electrical equipments adopt controllable silicon, carrying out PID regulation and control by program control. It is suitable for the annealing of wire rod linear materials, copper pieces, stainless steel, and steal belt. Rush into nitrogen under vacuum state for annealing, non-nitriding, and non-decarburization, so as to make work pieces keep bright after annealing.

Purpose

• Provide annealing heat treatment for all kinds of steels at rated temperature.
• Annealing and tempering work after heat treatment quenching.
• Eliminate the stress of all kinds of steels or non-iron materials.

Equipment Introduction

• Movable-type furnace cover, equipped with PLC control system; excellent operability and accuracy.
• Welded by shaped steel and steel plate; bottom is made of high-alumina bricks; height and weight resistance.
• Furnace cover adopts guide rail combined move mode; go up and down by air pressure or oil pressure; good stability.
• Electronic type temperature control recorder; can observe and read history records, and make best monitoring at any time.
• Automatic control system and man-machine management interface; make management become more efficient.

Characteristics

• Electric power heating.
• Good tightness; specially designed convection system, which makes furnace temperature uniform.
• Thermal insulation material is ceramic cellucotton, light weight, good thermal insulation effect, quick warming and cooling speed.
• There is an air spacer sleeve between furnace pipe wall and water loop, which effectively reduces thermal energy loss.
• Have a system that compulsorily reduces temperature, save discharge time, increases productivity, and reduces cost.
• Temperature control adopts optimized PID control system, rapidly reach steady state; high precision.
