1. The manufacturing process of the crane wheel can be carried out by casting or forging process.
The following is a brief description of the manufacturing process of crown wheel castings and forgings:
 
(1) Casting manufacturing process:
1) Mold preparation: According to the design requirements of the crane wheel, a mold suitable for casting is produced, usually using a sand mold or a metal mold.
2) Melting metal: Select appropriate metal material and heat it to the melting point to form liquid metal.
3) Pouring: Pour the molten metal into the prepared mold so that it fills the entire mold cavity.
4) Cooling and solidification: After the metal cools in the mold, it gradually solidifies into a solid state and forms the initial shape of the crane wheel.
5) Mold removal and finishing: Remove the solidified casting from the mold and perform trimming and sand removal to remove excess material and surface defects.
6) Heat treatment: Heat treatment is performed on castings to adjust the structure and performance and improve strength and wear resistance.
7) Mechanical processing: Necessary mechanical processing is performed on the castings, such as turning, milling, drilling, etc., to achieve the required size and accuracy.
 
(2) Forging manufacturing process:
1) Material preparation: Select appropriate metal materials, usually alloy steel or stainless steel.
2) Heating: Heating the metal material to the appropriate temperature to make it plastic.
3) Forging: Using pressure equipment (such as hammering or press), the heated metal material is placed in the mold, and pressure is applied to deform it to form the preliminary shape of the crown wheel.
4) Heat treatment: Heat treatment is performed on forgings to adjust the structure and performance and improve strength and wear resistance.
5) Mechanical processing: Necessary mechanical processing is performed on the forgings, such as turning, milling, drilling, etc., to achieve the required size and accuracy.
6) Surface treatment: As needed, perform surface treatment on the forgings, such as spraying anti-rust coating or surface polishing.

2. Crane wheel forgings are usually made of high-strength metal materials. Common materials include the following:
(1) Alloy steel: Alloy steel is a steel material whose properties are improved by adding alloy elements. Common alloying elements include chromium, nickel, molybdenum, etc. Alloy steel has excellent strength, hardness and wear resistance, making it suitable for crane wheels that can withstand high loads and harsh working conditions.
(2) Carbon steel: Carbon steel is a steel with a high carbon content. It has good strength and rigidity, and can obtain good hardness with appropriate heat treatment. Carbon steel is relatively cheap and widely used in the manufacture of crane wheels.
(3) High alloy steel: High alloy steel is steel containing a higher proportion of alloy elements (such as chromium, nickel, molybdenum, titanium, etc.). High alloy steel has higher strength, corrosion resistance and wear resistance, and is suitable for crane wheels that withstand high temperatures, corrosion or special working conditions.
(4) Stainless steel: Stainless steel is a metal material with good corrosion resistance, and the main alloying element is chromium. Stainless steel has good strength, wear resistance and corrosion resistance, and is suitable for crane wheels used in humid and corrosive environments.
 
The specific choice of material depends on the specific working environment, load requirements, and expected performance and life of the crane wheel forging. When selecting materials, factors such as mechanical properties, wear resistance, corrosion resistance, and weldability need to be comprehensively considered, and must comply with relevant standards and specifications.
