Ball annealing furnace

 

The full name of the ball annealing furnace (furnace Spheroidizing), the full name of the well type ball annealing furnace, well type of ball annealing furnace, or referred to as the furnace. Mainly applicable to eutectoid steel and hypereutectoid steel workpieces such as carbon tool steel, alloy tool steel, bearing steel, heat treatment etc.. The globular pearlite spheroidization annealing furnace spheroidizing annealing, the cementite is spherical particles dispersed in the ferrite matrix, and lamellar pearlite compared, not only low hardness, easy machining and in heating and quenching, austenitic grain is not easy to grow, cooling workpiece deformation and cracking tendency. In addition, for some need to improve the cold plastic deformation, such as stamping, cold heading of hypoeutectoid steel can also sometimes using spheroidizing annealing.

The annealing process is to make the carbide in the steel to be carried out. Will workpiece heated to the cotectic line more than 20 to 30 DEG C, insulation for a period of time, and then slowly cooled to slightly below the eutectoid temperature, and stay for a period of time, the organization transformation is completed, in the ferrite matrix uniformly distributed spherical or granular carbides.

Spheroidizing annealing furnace is combination of bell type annealing furnace and well type annealing furnace, which both bell type annealing furnace excellent atmosphere convection and circulation system, well type annealing furnace has the advantages of simple operation method, has the bell type annealing furnace can not match the high price.

Characteristics of the ball annealing furnace

1, the barrel of the ball annealing furnace is made of stainless steel, and the service life is long;

2, spheroidizing annealing furnace is designed to streamline the top of the dome, the atmosphere of the resistance;

3, the diversion block is made of heat resistant stainless steel, which has stronger bearing capacity and longer service life, and the guide seat can be disassembled and assembled separately, and the maintenance and the maintenance are more convenient;

4, convection motor using bell-jar furnace special sealing motor, excellent sealing, maintenance is simple; the convection fan blade is made of heat resistant stainless steel use and long service life.

5, unique strong convection air cycle design

6. The uniformity of the temperature in the furnace is good, and the hardness of the wire after the annealing treatment is good.

7, using nitrogen and methanol decomposition gas as a protective atmosphere, annealed wire nonscale.

8, the use of strong cold air machine, speed up the process of cooling temperature, effectively improve the production efficiency.

9, spheroidizing annealing furnace computer control system, the temperature history curve; process recipe written 'storage' call; real-time monitoring of work; can be at any time the historical process data; on the computer direct control for super.

10, with the use of infrared gas analyzer, automatic control of the furnace atmosphere of carbon potential.

11, automatic control system, the main electrical components are imported products.
