Abstract

A continuous hot rolling apparatus comprises: a sizing press for forcing down a rolled plate in the width direction supplied from a heating furnace to press the rolled plate to have a prescribed width, roughing mills for rolling said pressed rolled plate, a winding / unwinding machine for winding and unwinding the rolled plate rolled by said roughing mills, a crop shear for shearing the leading end and the tailing end of the rolled plate that has been unwound, an running joining machine that can travel at the conveying speed of the unwound rolled plate for joining the tailing end of the preceding rolled plate and the leading end of the succeeding rolled plate that have been sheared by said crop shear, a finishing mill for carrying out finish rolling of the joined rolled plates, a winding machine for winding the rolled plate that has been subjected to finish rolling, and a cutting machine positioned on the entrance side of said winding machine for cutting the rolled plate in accordance with the wound quantity.

Description

technical field

[0001] The present invention relates to a rolling material joining device for joining the rear end of the preceding rolling material and the front end of the following rolling material of the rolling material running in the hot rolling equipment, and a continuous hot rolling equipment equipped with the device . Background technique

[0002] In conventional hot rolling facilities (hot flat rolling mills), profiles rolled by a roughing mill are supplied to other finishing mills to obtain a strip having a desired thickness. However, in this equipment, it is impossible to roll all the rolled material uniformly, and the front end and the rear end of the rolled material are prone to defects. As a result, the raw material utilization rate of the rolled material is reduced, and the belt There was a problem that it was difficult to increase the rolling speed due to the engagement / discontinuity of the front end portion and the rear end portion.

[0003] In order to s...

Embodiment Construction

[0063] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each figure, the same symbol has the same meaning.

[0064] Figure 8 is a side view of the first embodiment of the present invention. In this figure, the rolling material joining device 20 of the present invention includes a trolley 22 that travels along the rolling direction shown by the arrow; Lifting rear end pinch roll 24; the front end pinch roll 26 that is installed on the trolley 22 and horizontally clamps the front end of the rolling material 2 behind; The processing device 28 that cuts the upper surface of the front end portion of the material 2; the reduction flame furnaces 30a, 30b that keep the processed surface in a reduced state; A crimping device 32 for rejoining the rolled materials 1, 2 compressed to substantially the same thickness.

[0065] The above structure and figure 1 The conventional technique shown is the same. In the rolle...
