Spheroidizing annealing is mainly used for hypereutectoid carbon steel, alloy and tool steel (such as steel used for manufacturing cutting tools, measuring tools and dies). Its main purpose is to reduce the hardness, improve the machinability, and prepare for later quenching. This process is good for plastic processing and cutting, and also can improve the mechanical toughness.
Scope of application：
specializes in spheroidizing annealing of wire material which are low and middle carbon steel，allow steel and bearing steel.
Main Performance Characteristics of Pit Type Furnace
1. The pit type furnace uses a straight-end sealed motor with a super convection fan to make the furnace temperature more uniform.
2. The pit type furnace has excellent sealing performance and the most effective thermal breakage structure, so the insulation is stronger.
3. The automatic pressure control inside the furnace of the equipment is safe and worry-free.
4. Advanced man-machine interface, powerful and easy to operate.
If your company is involved in automotive products or high requirement parts，a central monitoring system would be the best choice you will make.The systems effectively decrease
defective products and uphold manufacturing quality，and quickly break even your investment.
