Abstract
Abstract An improved insert for a roller entry guide box for use with steel mills and in particular steel rod mills is disclosed wherein a replaceable machined guide insert is provided to guide stock into the working mill rolls, insuring accurate centering of the same, whereby the insert can be readily changed when it becomes worn so as to insure continued accuracy and precision with a minimum of cost. The insert is a cylindrical member which is insertable into the guide box cavity adjacent the discharge end thereof and cooperates with a static guide member to form a continuous channel for reception of the stock. The insert has a funnel-shaped interior bore which serves to guide the stock onto the desired center line so that it passes along a center line between the guide rolls, which then feed the stock into the working rolls. Unique adjustment means are also provided to control the spacing of the guide rolls relatively of the center line.
