Round steel refers to long solid steel with circular section
Its specification is expressed in millimeters of diameter, such as & quot; 50" That is, round steel with a diameter of 50 mm
Round steel is divided into hot rolling, forging and cold drawing
The specification of hot rolled round steel is 5
5-250mm
Among them: the small round steel of 5
5-25mm is mostly supplied in bundles by straight bars, which is often used as reinforcement, bolts and various mechanical parts; Round steel larger than 25mm is mainly used for manufacturing mechanical parts or seamless steel tube billets
Standard of round steel
Standards: (gb699-1988, gb700-1988, gb3077-1988, gb702-1986, QJ / hg02
17-1991)
The following table shows the detailed standards of round steel:
In the mold production cost, the material cost generally accounts for 10% ~ 20%, while the machining, heat treatment, assembly and management costs account for more than 80%
Therefore, the process performance of mold materials is one of the main factors affecting the mold production cost and manufacturing difficulty

Machinability
—& mdash; Hot working performance refers to thermoplastic, processing temperature range, etc& mdash;& mdash; Cold working performance refers to cutting, grinding, polishing, cold drawing and other processing performance

Quality improvement
1
The modification of inclusions by trace elements such as Ca and rare earth can change the structure, morphology and physical properties of inclusions in steel, spheroidize and refine inclusions in steel, so as to improve the mechanical properties of steel

2
High temperature diffusion heat treatment of ingot can improve the composition heterogeneity of ingot and improve the transverse properties of steel

3
In terms of hot working, repeated upsetting and multi-directional rolling of steel ingot can not only reduce the level of carbide segregation in steel, but also improve the anisotropy of steel

4
The purity of steel has a great impact on the isotropic properties of steel materials
The use of secondary refining technology (including vacuum refining, ESR and ladle powder spraying, etc
) can improve the purity of steel, especially reduce the content of harmful impurities in steel, which is very beneficial to improve the properties
