Analysis of annealing production line for high ductility cold rolled ribbed steel bars from Zhengzhou Gou's

Brief introduction to the selection characteristics of high ductility cold-rolled ribbed steel bar annealing production line

According to the different needs of customers, our company divides the configuration selection of the high ductility cold-rolled ribbed steel bar annealing production line into four standard configurations. Users can configure and select according to the required specifications. The following is a brief introduction to the different characteristics of each configuration. :

1. Select and configure an 800KW medium frequency production line. The main motor of the rolling mill in this configuration is 160KW. The flying shear is controlled by a 30KW servo motor. It can shear diameters of Φ12-Φ14. This configuration is the best choice for the production line of steel bars with diameters of Φ12 and Φ14.

Note: This device is designed for Φ12 ribbed steel bars. If this configuration is used to produce steel bars with a diameter of less than Φ10, the production cost will increase, because the inner hole of the 800KW medium frequency sensor (replaceable) is relatively large, and the space for producing fine-sized products is large, and heating A lot of power loss will be wasted during this period, resulting in a waste of power.

2. Select and configure a 600KW medium frequency induction heating equipment production line. The main motor of the rolling mill in this configuration is 132KW. The flying shear is controlled by an 11KW servo motor. It can shear steel bars with a diameter of Φ10 or less. This configuration is better for producing steel bars with a diameter of Φ8-10. choose.

Note: If this configuration is used to produce steel bars with a diameter of Φ10 or more, the inner hole of the first sensor (replaceable) is too small and cannot penetrate steel bars with a diameter of 12 or more. Secondly, it has an impact on the production speed, because the 600KW intermediate frequency power is small and the speed is too fast. The temperature increases. If it does not go up, the Φ12 steel bar flying shear will not cut. If a heavy-duty flying shear is selected, the speed will be affected, the cost performance is not suitable, and the product quality is unstable.

3. Select and configure a 500KW medium frequency production line. The main motor of the rolling mill in this configuration is 110KW. The flying shear is controlled by an 11KW servo motor. It can shear steel bars with diameters below Φ8. This configuration production line can produce steel bars with diameters below Φ8, 7, 6.5, and 5.5. Steel bars are the better choice.

Note: If this configuration is used to produce steel bars with a diameter of Φ8 or more, it will have an impact on the production speed. Because the 500KW intermediate frequency power is small and the speed is too fast, the temperature cannot be increased. The product quality is unstable. The flying shear of steel bars with a diameter of Φ8 or more is affected. This configuration It is the choice of customers when the power supply power is not allowed.

Comparative analysis of saving materials

1. One production line can produce 20,000 tons of high-ductility cold-rolled ribbed steel bars per year.

2. The designed and calculated strength of high-ductility cold-rolled ribbed steel bars is 415MPa, and the designed and calculated strength of hot-rolled grade III steel bars is 360MPa, an increase of 15%.

3. 20,000 tons of high-ductility cold-rolled ribbed steel bars can save steel consumption compared to hot-rolled grade III steel bars: 2×15%=0.3 (10,000 tons)

In summary, high ductility cold rolled ribbed steel bar annealing production line. The production line project has a short investment payback period and a high return on investment.
