Automatic armor steel positioning device for heating furnace

Abstract

The invention provides an automatic armor steel positioning device for a heating furnace. The automatic armor steel positioning device comprises a furnace inside positioning machinery connecting rod, a limiting switch, a baffle and a baffle position retaining device, wherein the furnace inside positioning machinery connecting rod comprises a furnace inside part and a furnace outside part; the furnace outside part is used for mounting a limiting switch shifter; the baffle is arranged on the furnace inside part and positioned in a path by which a steel billet enters the heating furnace; when the steel billet is contacted with the baffle, the baffle is used for driving the furnace inside part, the furnace inside part is used for driving the furnace outside part and the limiting switch shifter; the limiting switch shifter is connected with the limiting switch and used for driving the limiting switch; the baffle position retaining device is connected with the furnace outside part and used for keeping the baffle in an initial position when an external force is not applied to the baffle. The automatic armor steel positioning device can be used for accurately and effectively positioning the steel billet, effectively determining the position of the steel billet, preventing the steel billet from colliding with the furnace wall of a furnace opening of the heating furnace and impacting the buffer baffle, and effectively improving the production safety and reliability.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to an automatic steel loading and positioning device for a heating furnace. Background technique [0002] The heating furnace is the leader of the steel rolling production line. Whether the heating furnace can ensure safe and normal operation, whether it can realize comprehensive automatic operation, and heat up qualified steel slabs is crucial to the safe, continuous and smooth production of the entire rolling line. has a crucial decisive role. [0003] In order to improve the automation level of the heating furnace, the existing technology generally realizes the positioning of the steel billet through the cold metal detector in front of the furnace and the encoder fixed on the second cantilever roller table motor in the heating furnace. When the tail of the billet passes the cold inspection in front of the heating furnace, the roller table is reduced from high speed to medi...
