Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting and rolling production, in particular to a billet steel separating device for a walking furnace rack. Background Art

[0002] The loading platform of the walking beam furnace adopts a fixed beam and a movable beam to guide the billets forward in a cycle and guide the billets onto the roller. Since there is no control over the billets during the guiding process, multiple billets often fall onto the roller at the same time, causing a huge impact on the roller and possibly damaging the roller. In addition, the roller cannot carry multiple billets, requiring manual processing, which is labor-intensive, risky and inefficient.

[0021] Both the second-stage steel separating sliders 8 and the third-stage steel separating sliders 9 have a structure with a spire triangle with a flange on one half and a spire triangle without a flange on the other half. The structures of the second-stage steel separating sliders 8 and the third-stage steel separating sliders 9 are symmetric on both sides with the connecting line of the two spires as the axis of symmetry. Pin through holes 10 are symmetrically provided on the spire triangle with a flange structure.

[0022] Working principle: The incoming billet is placed on the first-stage loading table 1. Through the cyclic operation of the process of driving the first-stage movable beam 12 to rise, advance, descend, and retreat by the driving motor of the first-stage movable beam 12 at the first-stage loading table 1, the billet is gradually introduced onto the second-stage loading table 2. Through the control of the steel separating slider of the second-stage loading table 2, most of the billets are spaced apart. Even if there are individual billets that are not separated, they can be completely separated through the control of the steel separating slider of the third-stage loading table 3. According to different rolling varieties, the fastening screws of the pin through-hole 10 of the steel separating slider can be removed, and the slider can be rotated 180 degrees around the pin and then re-fastened, eliminating the impact on the roller table when multiple billets fall onto the roller table simultaneously, so as to avoid damaging the roller table. If multiple billets fall onto the roller table simultaneously, the motor cannot drive the roller table and manual handling is required. The labor intensity is reduced through the automatic steel separating slider. If multiple billets fall onto the roller table simultaneously, the falling angle of the billets is uncertain, avoiding the safety risk of people passing nearby.
