Detailed Explanation of the Crusher Platen Heat Treatment Process-Innally

Product Details

Raw Material Preparation
Select the appropriate material, typically high-manganese steel or alloy steel.
Cut the raw material and produce the platen blank according to the design drawings.
Rough Machining
Preliminary machining of the platen blank removes excess material to create a platen that is close to its final shape.
Normalizing
Heat the platen to an appropriate temperature (generally 850-900°C) and hold for a period of time.
Then cool in air to refine the grain size and eliminate stresses, preparing it for subsequent heat treatment.
Quenching
Heat the platen to austenitizing temperature (generally 1050-1100°C) and hold for a period of time. Rapid cooling, typically using water or oil as the cooling medium, produces a martensitic structure, increasing hardness and strength.
Tempering
The quenched press plate requires tempering to reduce hardness and increase toughness.
Heat the press plate to an appropriate temperature (generally 200-300°C), maintain the temperature for a period of time, and then slowly cool it.
Finishing
The heat-treated press plate is finished to achieve the dimensions and surface roughness specified in the drawing.
Surface Treatment
If needed, the press plate can undergo surface hardening treatments such as carburizing and nitriding to further improve surface wear resistance.
Quality Inspection
The heat-treated press plate is inspected for various indicators, including hardness, metallographic structure, and dimensional accuracy.
This ensures that the press plate meets the intended use.
Packaging and Shipping
Qualified press plates are cleaned, treated with rust prevention, and then packaged.
Finally, qualified press plates are shipped to customers or assembled into crushers. Through the above heat treatment process, the performance of the crusher platen will be significantly improved, ensuring the stable operation of the crusher under various working conditions.
