ASTM Standard Forged Steel Rolls Welding Alloy Steel Roller Shell

  2,In addition, we are also equipped with several heat treatment furnaces (equipment) to ensure that forgings meet their performance requirements after heat treatment.
 3, In order to ensure product quality, the company has a well-equipped laboratory that can conduct precise laboratory analysis of raw materials and mechanical properties.
  4,At the same time, the company also introduced high-precision processing equipment such as CNC lathes, machining centers, deep hole processing equipment, and milling machines to achieve full independent production from forgings to finished products.
  5,It is worth mentioning that our entire production process is controlled independently and there is no outsourced processing. This means that every step from raw material procurement, forging processing, heat treatment to finished product delivery is strictly controlled by us.
  6,Through refined management and cost control, we are able to provide customers with more competitive prices while ensuring product quality.
 

1, Raw material: use ESR ingot. ESR need to melt twice, secondary refining process.Non metallic inclusions in steel are absorbed by slag.
2, Heat - Natural gas heating furnaces are monitored and controlled by computer programs to ensure precise heating within set time and temperature range as required.
3, Forging
4, Normalized:can improve the toughness of steel
5, Aligning
6, Pre-machining
7, Make UT (ultrasonic) inspection
8, Heat treatment: Quenching&Tempering, to meet mechanical performance requirements.
9, Deep hole drilling
10, Precision machining, to achieve dimenssion on drawings.
