Abstract
The invention relates to a steel material of a chain. The steel material of the chain comprises, by weight, 2.3%-2.4% of C, 2.0%-2.1% of Ni, 0.3%-0.6% of Mg, 0.2%-0.3% of S, 0.3%-0.5% of Na, and the balance Fe. The obtained steel material of the chain is high in elongation and has good deformation adaptability.
Description
Technical field
The present invention relates to a kind of steel, particularly relate to a kind of Steel material of chain.
Background technology
The material of chain is many to be made up of iron and steel, and the kind of chain is a lot, has different performances according to different purposes.In the use procedure of pumping unit chain and flyer chain, certain requirement is had to the distortion adaptive faculty of chain, if distortion adaptive faculty is poor, then the work-ing life of chain is lower, and then add use cost, therefore develop and a kind of there is the strong chain steel material of distortion adaptive faculty, there is very large necessity.
Summary of the invention
The technical problem solved: the problem that Steel material of chain elongation is low.
Technical scheme: the invention discloses a kind of Steel material of chain, Steel material of chain consists of the following composition: C to be 2.3 wt% ~ 2.4wt%, Ni be 2.0 wt% ~ 2.1wt%, Mg be 0.3 wt% ~ 0.6wt%, S be 0.2 wt% ~ 0.3wt%, Na is 0.3 wt% ~ 0.5wt%, surplus is Fe.Method prepared by high elongation rate Steel material of chain is as follows: get required each composition according to above-mentioned weight percent, each composition is dropped in vacuum induction furnace simultaneously, carry out vacuum metling, Heating temperature to 1250 DEG C, rod iron is rolled into after melting, heat-treat again, after rod iron being heated to 800 DEG C, be cooled to room temperature gradually, prepare high elongation rate Steel material of chain.
Beneficial effect: the chain steel material prepared has higher elongation, the elongation of the firm material of chain is 8% ~ 10%.The Steel material of chain therefore with good elongation has extraordinary distortion adaptive faculty, can be a large amount of be applied in the use procedure of pumping unit chain.
Embodiment
Embodiment 1
Each composition is dropped in vacuum induction furnace simultaneously, C to be 2.3wt%, Ni be 2.1wt%, Mg be 0.6wt%, S be 0.3wt%, Na is 0.3wt%, surplus is Fe.Carry out vacuum metling, Heating temperature to 1250 DEG C, after melting, be rolled into rod iron, then heat-treat, after rod iron being heated to 800 DEG C, be cooled to room temperature gradually, prepare high elongation rate Steel material of chain.
Embodiment 2
Preparation method is with embodiment 1, and concrete component content is as follows: C to be 2.4wt%, Ni be 2.0wt%, Mg be 0.3wt%, S be 0.2wt%, Na is 0.5wt%, surplus is Fe.
Embodiment 3
Preparation method is with embodiment 1, and concrete component content is as follows: C to be 2.3wt%, Ni be 2.1wt%, Mg be 0.5wt%, S be 0.3wt%, Na is 0.4wt%, surplus is Fe.
Test of elongation rate has been carried out to the Steel material of chain of the embodiment 1 prepared, embodiment 2, embodiment 3.Test result shows, the Steel material of chain elongation of embodiment 1 is 8%.The Steel material of chain elongation of embodiment 2 is 10%.The Steel material of chain elongation of embodiment 3 is 9%.All possess higher elongation, therefore there is good distortion adaptive faculty, can be widely used in chain Forging Technology.
Claims (5)
