How to control temperature and time during forging to ensure the quality of standard bearing ring blanks?

Temperature control: precision and dynamic adjustment
1. Preheating stage
Preheating before forging is a key step to ensure uniform heating of the material and reduce forging stress. YININ uses advanced heating furnaces to preheat the material to a suitable temperature range through precise temperature sensors and control systems. For different types of bearing materials (such as carbon steel, stainless steel, etc.), we set different preheating temperatures to ensure that the material reaches the ideal microstructure and thermoplasticity before forging. For example, the preheating temperature of stainless steel bearing ring blanks is usually set between 900°C and 1100°C to optimize its corrosion resistance and mechanical properties.
2. Forging temperature window
Temperature control during forging is crucial, which directly affects the fluidity and formability of the material. Based on long-term technical accumulation, YININ has established a strict forging temperature window for each bearing material. Within this window, the material can maintain good plasticity while avoiding grain growth and mechanical property degradation caused by overheating. Our technicians monitor and adjust the temperature of the heating furnace in real time to ensure that the material is always at the optimal temperature during the forging process.
3. Cooling stage
The cooling process after forging should not be ignored either, as it determines the microstructure and hardness of the material. YININ uses advanced cooling technology and equipment, such as quenching oil tanks or air cooling devices, to accurately control the cooling speed and method according to material characteristics and product requirements. Through a reasonable cooling strategy, thermal stress can be effectively reduced and the strength and toughness of the bearing ring blank can be improved.

Time control: precision and collaborative operation
1. Heating time
The length of the heating time directly affects the temperature uniformity and energy consumption of the material. YININ optimizes the heating efficiency and heat transfer path of the heating furnace, combined with the thermal conductivity of the material, to accurately calculate and set the heating time. Our heating furnace uses an advanced combustion control system that can automatically adjust the heating power according to the thickness and shape of the material, ensuring that the ideal preheating temperature is reached in a short time while reducing energy waste.
2. Forging time
The control of the forging time is directly related to the degree of deformation of the material and the evolution of the microstructure. YININ uses advanced forging equipment and processes, such as multi-directional forging, precision die forging, etc., combined with precise forging time control to ensure that the bearing ring blank obtains uniform deformation and dense microstructure during the forging process. Our technicians continuously optimize forging parameters through simulation and field tests to ensure that each forging can achieve the best results.
3. Cooling time
Precise control of cooling time is essential to avoid thermal cracks and maintain material properties. YININ has developed a detailed cooling schedule based on material properties and product requirements. By precisely controlling the temperature, flow rate and cooling time of the cooling medium, we can effectively adjust the cooling rate of the material to obtain the ideal microstructure and mechanical properties.
