High-ductility two-side rib steel bar production links

High-ductility cold-rolled ribbed steel bar production links

Yes, willQ235、Q215、Q195The ribbed bar with crescent on both sides is formed on the surface of the hot-rolled round bar by cold rolling. After studying the advantages and disadvantages of cold rolling process equipment at home and abroad, the production line of cold-rolled ribbed bar with crescent on both sides is successfully developed, which completely solves the problem that the elongation of cold-rolled ribbed bar is not up to the standard for a long time. From paying-off, steel bar rolling, strength control, extension control, fixed-length cutting, two-sided blanking, automatic bulldozing, coiling and winding, all of them are automated. After quenching and tempering, all the technical indexes of the products exceed those of hot rolling.HRB400(Grade III steel)The national standard, the steel bar performance does not rebound, the extension does not drop, is the third grade steel substitution product. Saving Precious Metals in Grade III SteelVVanadium,NbNiobium,TiTitanium. The unit has the advantages of convenient operation, no need of roller replacement for replacing different steel bars, simple machine manufacturing and adjustment, no need of lubricating powder and cooling liquid, low production cost, being a set of high-efficiency straight production line, and being capable of being matched with a take-up machine for winding.

Jin Tongcheng Machinery constantly dares to refresh the new record of steel bar processing, and constantly introduces new products to meet the needs of the rapid development of the market; the products are energy-saving, efficient, durable, reduce the amount of labor, and improve product efficiency.

The product uses five rounds of Luogang to remove phosphorus, and the effect of phosphorus removal is thorough.

Double rolling process is adopted, and the auxiliary rolling mill and the main rolling mill both adopt diamond alloy rollers with active synchronous process. The roll is selected from Zhuzhou601Diamond brand carbide.

The finished steel bar reaches the standard of high-ductility cold-rolled ribbed steel bar andGB13788-2008Standard.

Roll loss: produced by single groove according to the type of steel bar: Φ6/1000T、Φ8/1200T、Φ10/3000T、Φ12/4000T、Φ14/6000T。

Double-well type take-up is adopted, which can be switched automatically without shutdown, and the appearance of the take-up is the same as that of the three-level steel coil.

The straight bar and the take-up can be switched automatically without stopping the machine.

Rolling bearings are used in dephosphorization, cold rolling, transmission and cutting of the production line, which have long service life and good interchangeability.

The speed is stepless and adjustable, and the round bar can pass through smoothly after butt welding,(No waste)The main engine gear adopts20CrmnTiThe material is carburized and quenched, with beautiful teeth, strong load capacity and long service life.

The guide mouth of the machine is made of wear-resistant material, which can reduce the production cost.

ImportedPLCTouch screen CNC operating system, high degree of automation.  

The whole machine adopts frequency conversion speed regulation and frequency conversion.(Or servo)Flying shear cutting technology can save electricity40%Above, the linear speed can reach100—180Meters/The production efficiency is improved by more than one time. The rolling mill adopts a double-driving continuous rolling transmission system, which is synchronous and stable, has high energy-saving efficiency, and the efficiency is doubled. The reducer adopts a 20CrMnTiMaterial carburizing treatment, long service life.

The medium frequency or supersonic frequency induction heating system is adopted for quenching and tempering, and the spiral heating principle is adopted. The steel bar is evenly heated, the strength index is stable, and it is not easy to be corroded.

The straightening machine adopts the multi-wheel straightening process, which has good straightening effect and slight damage to the steel bar. The frequency conversion or servo flying shear cutting system is used for cutting, which has high automation degree and small cutting error.

Two-sided blanking, automatic bulldozing device, can save manual bulldozing, automatic bulldozing device can greatly reduce the labor intensity of employees.

Equipped with fully automatic pneumatic baling machine to make binding faster.
