Abstract

PURPOSE: To enable adjustment of cooling time depending on the material width and reduce the facility costs, in the cooling bed in a bar steel rolling facility, by providing a mechanism to make the transfer pitch of walking beam variable.
CONSTITUTION: When transferringa material 4 on a movable rake 6, a drive line shaft 13 has eccentric cams 23, 14, and the rotation of the eccentric cam 14 causes a lever 17 to turn about a pin 18, so that the movable rake 6 makes a horizontal motion l. Due to the rotation of the eccentric cam 23, levers 7, 8 provide a vertical motion (lift, h) of the rake 6. Suppose the amount of eccentricity of the eccentric cam 14 as RA, the overall length of the lever 17 as L1, and the distance between fulcrum pins 18 to 16 as L2, it follows that l=L1/L2.RA. Therefore, in order to change the transfer pitch l, the distance L2 between pins 18 to 16 should be changed by turning the screw shaft 20. Thus, it is possible to adjust the cooling time depending on the width of material 4, so that the length of cooling bed may be shortened, and that the facility cost may be reduced.
