Characteristics of semi solid honed pipe

1.Material characteristics:

1045 steel is a medium carbon steel in the US standard, with a carbon content between 0.42% and 0.50%. This steel has high strength and good toughness, and after proper heat treatment, it can obtain good comprehensive mechanical properties.

Its tensile strength is usually between 580-750MPa, its yield strength is between 355-450MPa, and its hardness is around HB170-220.

2. Production process:

Seamless pipe production: First, seamless steel pipes are produced through hot rolling or cold drawing. The hot rolling process is to heat the steel billet to a high temperature, and then roll it through a piercing machine, a tube rolling mill and other equipment to form a seamless steel pipe; the cold drawing process is to draw the hot-rolled steel pipe at room temperature to reduce its diameter and thin its wall thickness, thereby improving dimensional accuracy and surface quality.

Honing: The seamless steel pipes are honed. Honing is a high-precision inner hole processing technology that uses a honing head to perform high-speed rotation grinding on the inner hole surface of the steel pipe to remove tiny defects on the inner hole surface, reduce surface roughness, and improve the size accuracy and shape accuracy of the inner hole.

3. Technical parameters:

Size specifications: The outer diameter is generally between 10-500mm, the wall thickness is between 2-50mm, and the length is determined according to customer needs, usually between 1-12m.

Tolerance accuracy: The inner hole tolerance can reach H8-H9 level. The outer diameter tolerance, wall thickness tolerance, etc. also have strict standard requirements. The specific values are determined according to different production standards and customer needs.

Surface roughness: After honing, the inner hole surface roughness can reach Ra0.2-Ra0.8μm, with high surface smoothness, which is beneficial to reduce fluid resistance and wear34.

4. Application areas:

Hydraulic system: widely used in cylinder barrels and piston rods of hydraulic equipment such as hydraulic cylinders, hydraulic pumps, hydraulic valves, etc., which can withstand high pressure and ensure the normal operation of the hydraulic system4.

Mechanical manufacturing: used to manufacture various mechanical parts, such as transmission shafts, guide rods, sleeves, etc., where high requirements are placed on the precision and surface quality of parts.

Automobile industry: It can be used in the manufacture of automobile engine cylinders, pistons, connecting rods and other parts, as well as automobile suspension systems, steering systems and other parts.

Other fields: It is also widely used in aerospace, shipbuilding, mining machinery, petrochemical and other fields.
