A Quick Handling Method for Coiler Unwinding

Abstract

The present invention relates to a rapid treatment method for coiler unwinding. The rapid treatment method comprises: providing a steel coil support frame with a movable hinge joint and an adjustment mechanism, and a steel coil trolley; lifting the steel coil support frame onto the steel coil trolley, and fixing; driving the steel coil trolley to the position below the unwinding steel coil, and lifting so as to bear against the steel coil and support the steel coil through the left support arm and the right support arm of the support frame; contracting the drum, and making the outlet pressing roller arranged above the drum press the outer ring of the steel coil, such that a gap is formed between the drum outer wall and the steel coil inner ring of the unwinding coil; adopting a penetrating belt rod to penetrate from the gap, and making the bundle belt penetrate into the inner ring gap; inching the drum to rotate to make the steel coil rotate 180 DEG, binding the bundle belt on the position opposite to the inner ring with the bundle belt, and tightening; making the drum maintain the contracting state, lifting the outlet pressing roller, and making the steel coil trolley descend, such that the loose part is tightened with the bundle belt; and inching steel coil trolley to move toward the outer side, and lifting away the steel coil. With the rapid treatment method of the present invention, the steel coil unwinding can be rapidly and conveniently treated.

Description

technical field [0001] The invention relates to a coiler of a rolling mill, in particular to a coiling treatment method of the coiler of a rolling mill. Background technique [0002] The coiler is an auxiliary equipment in the steel rolling workshop that coils hot-rolled or cold-rolled steel into a coil shape. It is arranged after the finished stand on the hot strip continuous rolling mill (hot continuous rolling unit), cold strip continuous rolling mill and wire rod rolling mill. ; On a single stand reversing cold strip mill, it is installed before and after the rolling mill. In addition, it is also installed in various finishing units such as continuous pickling unit, slitting, annealing, coating and so on. The surface of the common coiler reel is composed of several fan-shaped blocks, and the fan-shaped blocks are connected by tension springs, which can realize the expansion and contraction of the reel. When the coiler is working, the reel is opened to the maximum diame...

Problems solved by technology

The inventive method uses the floating and deviation correction functions of the coiler to correct the coiling position before the expansion of the inner ring, thereby ensuring that the subsequent coiling is normal. The processing speed of has no effect and does not solve the problem
