Technical Field

The invention belongs to the technical field of steel processing and manufacturing, and particularly relates to a monitoring and alarming system and method for a billet feeding process.

Background

The push type heating furnace is a continuous heating furnace which completes the movement of steel billets in the furnace by a pusher, as shown in figure 1, one side of a feed inlet of the existing push type heating furnace is provided with a pair of automatic steel feeders 5 and a supporting track; the support rail is provided with a gap for the automatic steel feeder 5 to push along the Y direction. Wherein one notch corresponds to an automatic steel feeder 5. During operation, the billet 6 moves along the support guide rail to pass through the 2 gaps along the X direction, then the automatic steel feeding machine 5 is started, the protection door of the feeding port 41 is opened, and the billet 6 is pushed to move along the Y direction until entering the heating furnace 4 from the feeding port 41. In the above-described process, in the feeding process in which the billet 6 moves in the X direction, if the feeding device that pushes the billet 6 fails or the operating time deviates, the feeding device stops operating when the billet 6 easily passes through only one of the notches. At this time, the pair of automatic steel feeders 5 is started to enter a material pushing process to push the steel billet 6 to move along the Y direction, and the steel billet 6 is inclined under the pushing action of one automatic steel feeder 5 because the automatic steel feeder 5 at the other notch cannot contact the steel billet 6, so that the steel billet 6 is stopped at the feeding port due to the inclination and cannot smoothly enter the heating furnace 4, and potential safety hazards exist.
