Lower raising product size precision, while improving lumber recovery index, lowering production cost as urgent problem to be solved.
Utility model content
In view of the above-mentioned deficiency of the prior art, technical problem to be solved in the utility model is to improve the production of bar round steel
Product dimensional accuracy improves bar round steel production lumber recovery, lowers production cost.
To achieve the above object, the utility model provides a kind of rule circular hole system producing bar round steel, and use is ellipse
The rule circular hole of circle-circle-circle, including oval groove K2 and circle-circular hole design；Wherein round-circular hole is designed as including time circle
Pass K0, secondary circular hole K1, wherein the round of finished product sortie circular hole (K0) ensures product size precision, and sortie is justified before finished product
The circle of pass (K1) enables rolled piece can smoothly enter into finished product sortie circular hole, and rolling deformation occurs according to preset machined surface,
To ensure the dimensional accuracy of round steel product.
Further, the rule circular hole system of the production bar round steel, further includes the rolling mill inlet guide of circle-circular hole
Device；
Further, further, the rule circular hole system of the production bar round steel further includes calculating rule sired results skill
Rolling parameter chart, the rolling mill speed for calculating rule sired results skill；
In the more excellent embodiment of the utility model, the rolling size chart of the rule sired results skill includes workpiece measurement, rolls
Part area, length of rolled piece, roll gap, motor speed；
In the more excellent embodiment of the utility model, the rolling mill speed of the rule sired results skill is that one batch of rotating speed~six batch turns
Speed, rotating speed are 200~700r/min；
