Embodiment 1

[0021] The present invention is an automatic steel tapping method in a steel rolling heating furnace, wherein the steel type in the furnace is: 45# steel, the specification is Φ5.5mm in diameter, and the material distribution method is feed-in and empty-out (one billet is spaced between each billet) ; The steel type to be put into the furnace is: cord steel, the specification is Φ5.5mm in diameter, and the material distribution method is to enter two spaces and one space (every two steel billets are separated by a space for one steel billet).

[0022] Use the laser rangefinder installed on the furnace side to judge whether the steel billet will be delivered next time. The distance between the steel billet and the laser rangefinder is set to LJ, and the judgment data is set to LK=1.3m. When LK-0.1<LJ< When LK+0.04, that is, 1.2m<LJ<1.34m, it is judged that the state of the exit side of the heating furnace is the next billet discharge, and when LJ satisfies LJ≥1.34m, it is judged...

Embodiment 2

[0034] The invention relates to an automatic tapping method for a steel rolling heating furnace, wherein the steel types in the furnace are: two cord steels with a diameter of Φ6.5 mm, and the feeding method is two empty steps; three empty steps are spaced behind the cord steels (One empty step is the space required to place a billet, and this space is empty at this time), it is Y1215 steel, the specification is Φ6.5mm in diameter, and the distribution method is continuous; the steel type to be put into the furnace is: 80# steel, The specification is Φ6.5mm in diameter, and the fabric method is one air one.

[0035] Use the laser rangefinder installed on the furnace side to judge whether the steel billet will be delivered next time. The distance between the steel billet and the laser rangefinder is set to LJ, and the judgment data is set to LK=1.3m. When LK-0.1<LJ< When LK+0.04, that is, 1.2m<LJ<1.34m, it is judged that the state of the exit side of the heating furnace is the ...

Abstract

The invention provides an automatic steel tapping method of a steel rolling heating furnace. The furnace inlet and outlet sides of the heating furnace are set to be in four states, namely, the furnace inlet side steel billet feeding state and the furnace outlet side steel billet discharging state, the furnace inlet side steel billet feeding state and the furnace outlet side steel billet non-discharging state, the furnace inlet side steel billet non-feeding state and the furnace outlet side steel billet discharging state, and the furnace inlet side steel billet non-feeding state and the furnace outlet side steel billet non-discharging state. The automatic steel tapping method has the beneficial effects that full-automatic steel tapping of steel billets of different kinds and different distribution modes of the heating furnace is achieved, and therefore the labor intensity is relieved, the steel passing interval is stabilized, and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to an automatic tapping method for a steel rolling heating furnace. Background technique [0002] The process of pressing the steel ingot to change the shape of the billet between the rotating rolls is called steel rolling. On the one hand, steel rolling is to obtain the required shape, such as: steel plate, strip steel, wire rod and various section steel, etc.; on the other hand, it is to improve the internal quality of steel. Rebar, steel bar, electrical silicon steel, galvanized sheet, tinplate, including train wheels are all processed by rolling steel. [0003] The steel rolling method can be divided into hot rolling and cold rolling according to the rolling temperature; according to the relative motion relationship between the rolled piece and the roll during rolling, it can be divided into longitudinal rolling, horizontal rolling and skew rolling; according to the formi...
