Description

Гор чекатаную полосу подают с разматывател  к гильотинным ножницам, где производ т обрезку концов предыдущего и последующего рулонов, после чего эти концы сваривают встык. Сваренный шов зачищают на гратоснимателе , установленном за сварочной мащиной , и затем по длине шва выполн ют отверсти , предпочтительно круглые с диаметром не менее ширины шва.A hot-rolled strip is fed from the unwinder to the guillotine shears, where the ends of the previous and next rolls are trimmed, after which these ends are butt-welded. The welded seam is cleaned on a reamer mounted behind the welding machine, and then holes are made along the length of the seam, preferably round, with a diameter of at least the seam width.

Выполнение шва с отверсти ми позвол ет компенсировать перепад пластических свойств металла в районе сварного шва за счет изменени  деформируемого объема и тем самым устранить причину обрыва полосы в зоне шва.Making a seam with holes makes it possible to compensate for the difference in the plastic properties of the metal in the weld area by changing the deformable volume and thereby eliminate the cause of the strip breakage in the weld zone.
