Device for preventing billet from tipping in steel tapping and steel loading of hot rolling heating furnace and control method thereof

Abstract

The invention discloses a device for preventing a billet from tipping in steel tapping and steel loading of a hot rolling heating furnace. The device is arranged at the outer side of a furnace door, comprises a plurality of base, and also comprises hydraulic cylinders, tracks, a slide rod, and a heat-resisting cushion block, wherein the hydraulic cylinders and the tracks are arranged on each base; the slide rod is coaxially connected with a piston rod of each hydraulic cylinder; the heat-resisting cushion block is arranged at the end part of the slide rod; the slide rod is matched with each track in a sliding manner; the slide rod is vertical to the plane on which a fire hole is located; the slide rod is arranged inside a corresponding notch arranged on the end wall of the furnace body under a completely stretching state. A control method of the device for preventing the billet from tipping is also disclosed by the invention. By adopting the technical scheme, the billet is prevented from tipping in the steel tapping process and steel loading process of the hot rolling heating furnace; the fault treatment difficulty is reduced; a derivative security incident in the treatment process is avoided; meanwhile, the equipment needs to be protected; the treatment time is shortened; and the loss is also reduced.

Description

technical field [0001] The invention belongs to the technical field of production equipment in the metallurgical industry, and relates to the safety protection technology for tapping and loading steel in a hot-rolling heating furnace. More specifically, the invention relates to a billet anti-tipping device in the process of tapping and loading steel in a hot rolling heating furnace. In addition, the present invention also relates to a control method of the device. Background technique [0002] Below with the accompanying drawings ( figure 1 and figure 2 ) to analyze the existing technology. In the prior art, when the heating furnace makes mistakes in automatic steel loading or tapping, the slab 12 is often located between the roller table 10 and the furnace body 11, and some of them are in a suspended state without a fulcrum. [0003] Such as figure 1 Shown: For tapping, at this time, since tapping is completed by default, the system issues a command to close the furna...

AI Technical Summary

Problems solved by technology

[0006] Due to the heavy weight of the slab and the different states of each tipping, the handling is irregular and difficult to handle. The handler needs to approach the slab for several times to try the lifting point. It takes a long time to ensure that the lifting process will cause damage to peripheral equipment, and at the same time reduce the service life of the heating furnace
