Strip steel coiling tension control method and device
The invention relates to the field of steel rolling, in particular to a trip steel coiling tension control method. The method comprises the steps that when the strip steel head enters a belt wrapper,the coiling tension value is controlled to 35 to 65 MPa; when the belt wrapper descends and delays fo...

| description | The invention relates to the field of steel rolling, in particular to a trip steel coiling tension control method. The method comprises the steps that when the strip steel head enters a belt wrapper,the coiling tension value is controlled to 35 to 65 MPa; when the belt wrapper descends and delays for 4 to 5 seconds, the coiling tension value is controlled to be stepped to 50.05 to 92.95 MPa, then, the value is gradually reduced to 38.5 to 71.5 MPa; when the length of coiled strip steel reaches 1/5 of the total length of the strip steel, the coiling tension value is controlled to be graduallyreduced to 35 to 65 MPa; when the length of the coiled strip steel reaches 3/5 of the total length of the strip steel, the coiling tension value is controlled to be kept 35 to 65 MPa; when the lengthof the coiled strip steel reaches 4/5 of the total length of the strip steel, the coiling tension value is controlled to be gradually increased to 36.75 to 68.25 MPa until strip steel coiling is finished.
