DARING serial products-cold rolled steel application case

      

Cold rolling means to use rollers to further roll those materials that pass through hot rolling, hard sports removal and descaling under the temperature of compound metal recrystallization to let them recrystallize. Through repetitive processes of cold rolling-recrystallizing-annealing-cold rolling (repeat for two or three times), the metal within materials will change at molecular level (recrystallize). The compound metal formed has changed in physical property. Therefore, they have good surface quality, high smoothness, and precise product dimension. Moreover, the product performance and structure can fulfill some special requirements such as electromagnetic performance and deep drawing property.

A cold rolling factory of Wuhan needed better and more precise cold rolling technology, and thus contacted DARING R&D engineer. They also required the engineer to test and use DARING serial products on cold rolling steel machines.

The cold rolling steel factory now uses two types of frequency converter to simultaneously draw machines, frequency converters of an Italian brand and DARING serial frequency converter. The DARING frequency converters at site use the power of 250G/280P.

DARING serial products successfully address the required synchronous rotary speed of electric motor and balanced output torque of the cold rolling steel factory. They ensure self-adjustment, adaptation and smooth operation.


DARING uses the following parameters for frequency converter test:

F0.03=1;F0.05=1;F0.06=2;F0.08=2;F0.16=F0.17=10;

F1.01=185;F1.03=347;F1.04=50;F1.05=1000;F1.16=0;F1.17=0.5

F1.28=1;Use X1-X5 as the switching signal for electrovalence positive and negative rotation.

F2.12=3;F2.13=1.5;F2.22=9.5;

F8.10=1;F8.11=3;F8.12=150;F8.16=0.6;F8.17=0.8;F8.18=0.18

F8.19=3. Above parameter setup involves important debugging parameters. 


In-site technology improvement:

To address in-site needs, DARING teams have already developed expansion cards which can fit with the input of -10V~10V analogue module signal, fully meeting customer requirements.


Advantages:

1.DARING frequency converters involve higher performance price ratio and easier adjustment compared to foreign frequency converters with same power;

2.DARING frequency converters are energy saving, use advanced drive, involve low temperature rise in frequency converter and electric motor and more superior performance as a whole.

3.DARING serial products show high adaptability for adverse conditions.


DARING Electric has made constant breakthroughs and progresses to become industry leader. Welcome industry players to learn and join in DARING! Create our common future!
