Embodiment Construction

[0011] The production process of the 8630 forging for deep-sea oil production equipment according to the present invention will be further described in detail through specific examples below.

[0012] (1) Refining formula technology

[0013] 8630 is based on 30CrNiMo by adding V and appropriately increasing Mo to achieve an optimized ratio to improve hardenability and comprehensive mechanical properties, and is used to manufacture forgings with higher comprehensive mechanical properties than 30CrNiMo. Cr, Ni, and Mo are all elements that improve hardenability, and the addition of V is more obvious for grain refinement and hardenability improvement. Cr, Mo, Ni, and V are all strong carbide forming elements, which improve the overall hardenability, refine the structure, and improve the strength and impact toughness.

[0014] (2) Forging technology

[0015] The initial forging temperature of 8630 is 1200°C, and over 1200°C is likely to cause overheating or even overburning. De...

Abstract

The invention relates to a production technology of 8630 forging pieces for deep sea oil extraction equipment. The production technology comprises the following steps of a, forging, wherein the initial forging temperature is 1200 DEG C, the final forging temperature is 850 DEG C, and the forging ratio is greater than 4:1; b, carrying out heat treatment, wherein 900-920 DEG C normalizing is adopted, and then air cooling is carried out; the performance heat treatment technology temperature is 900 DEG C, the tempering temperature is 600-620 DEG C, and the air cooling can be carried out after heat preservation is carried out for appropriate time. Forging pieces which are manufactured by the production technology of the 8630 forging pieces for the deep sea oil extraction equipment have higher hardness, higher yield strength and higher tensile strength, and meanwhile, the forging pieces have good impact toughness and good elongation, and the forging pieces are mainly used for the deep sea oil extraction equipment.

Description

technical field [0001] The invention relates to a production process of 8630 forgings for deep sea oil production equipment. Background technique [0002] The materials of forgings for deep-sea oil production equipment mainly include 8630, etc. At present, the three major deep-sea oil production equipment manufacturers in the world do not use Chinese forgings to produce deep-sea oil production equipment. The reason is that the quality of our forgings cannot meet their product requirements. The main problems are that the mechanical properties are not up to standard, and there are defects such as looseness, microcracks, and coarse grains inside. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production process of 8630 forgings for deep-sea oil production equipment that can meet product requirements. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: the pr...
