Abstract
Description
Claims (11)
- One kind the steel billet that separates be rolled through a plurality of roll stands of arranging along a roll line with the product section in succession producing cross-sectional area and reduce and in succession product section have in the continuous mill of front end and tail end tail end with one first product section and join method on the front end of follow-up second product section to, said method comprising the steps of:Transfer rate with the speed of tightening up that surpasses follow-up second roll stand is operated one first roll stand;When first and second product sections when first roll stand comes out, lead and make them depart from the roll line of rolling mill, and enter route guidance to a welding station along one, lead back to the roll line of rolling mill then from welding station along a transfer path, rolling in second roll stand, to continue;When first product section is rolled, temporarily accumulate a first of first product section along transfer path in second roll stand;In the time interval that the first that accumulation is got up is rolled in second roll stand continuously, keep the tail end of first product section to be positioned at the welding station place;In the described time interval, keep the front end of second product section to be positioned at the welding station place, and temporarily accumulate a second portion of second product section along entering route simultaneously;Welding maintains in the described time interval front end and tail end; And the end of the such welding of release.
- 2. the method for claim 1 is characterized in that, before welding ends is rolling in second roll stand it is carried out deburring.
- 3. method as claimed in claim 1 or 2 is characterized in that, before product section is rolling in second roll stand it is heated again.
- 4. the method for claim 1 is characterized in that, described front end and tail end stop when welding at the welding station place.
- 5. become to have in the rolling mill of product section in succession of front end and tail end at the billet rolling that will separate, a kind of tail end that is used for one first product section joins the equipment on the front end of follow-up second product section to, and described equipment comprises:First and second roll stands of arranging along the roll line adjoining land of a rolling mill, and first roll stand can surpass the transfer rate running of the speed of tightening up of second roll stand;Guider, first and second product sections that come out from first roll stand that are used for leading make them depart from the roll line of rolling mill, and enter route along one they are directed to a welding station, along a transfer path they are led back to the roll line of rolling mill from welding station then, and get back to roll stand;First storage device, a first that is used for when first product section is rolled, temporarily accumulating first product section in second roll stand along transfer path;Holding device is used for keeping in the time interval that the first of accumulating first product that gets up is rolled in second roll stand continuously the tail end of first product section and the front end of second product section to be positioned at the welding station place;Second storage device was used in the described time interval, temporarily accumulated a second portion of second product section along entering route; AndWelder at described welding station place, the front end and the tail end that are used for maintaining weld together, so the end that discharges welding like this will allow first and second product sections to be rolled continuously and without interruption in second roll stand.
- 6. equipment as claimed in claim 4 is characterized in that, described holding device can be operated so that front end and tail end are stopped at described welding station place.
- 7. equipment as claimed in claim 4 is characterized in that, also comprises along transmitting route, being used for the welding front-end and back-end of described first and second product sections are carried out the device of deburring.
- 8. as claim 5 or 6 described equipment, it is characterized in that, also comprise being used for the device that before described second roll stand, heats again.
- 9. equipment as claimed in claim 5 is characterized in that, described first storage device comprise be used for the circle form accumulate a repeater of described first.
- 10. equipment as claimed in claim 5 is characterized in that, described arresting stop is included in entering of described welding station and transmits some driving pinch roll unit on the side.
- 11. the method for claim 1, its feature exists, and the cross-sectional area of described product section is in about 700 to 4400 square millimeters scope.
