Description

Gun barrel type online blank ejection device

Technical Field

The utility model relates to a gun barrel type online billet jacking device belongs to metallurgical industry sheet billet caster equipment technical field.

Background

The sheet billet continuous casting machine generally adopts the swing shear to shear the casting blank, and the swing shear has the functions of: (1) shearing a normal casting blank; (2) cutting the head and tail of the casting blank; (3) the buffer function is that when faults such as steel piling occur to the rolling mill and the casting blank cannot enter the heating furnace in a short time, the casting blank needs to be cut into fragments for buffering, so that continuous casting machine is ensured not to stop casting, and the casting machine is recovered to be normal after the faults of the rolling mill are well treated. The billet head, the billet tail and the fragment billet which are sheared by the swing shears firstly fall into a chute below the swing shears and then fall into a billet head hopper below the chute.

Because the opening degree of the chute of the thin slab continuous casting machine is small, and the chute is impacted by a heated casting blank for a long time, the surface of the chute becomes uneven, so that the accident that the casting blank is clamped in the chute and cannot fall into a billet head hopper often occurs, which is generally called as a billet clamping accident, and the production is seriously influenced.

The hazards of the green brick clamping accident are as follows:

(1) under the condition that the clamped blank cannot be timely and online processed, if the swinging shears continue to break, the casting blank can be accumulated in the chute, so that equipment accidents such as broken shearing edges of the clamped blank and the like and continuous casting blank laying accidents are caused; if the oscillating shears stop breaking, the oscillating shears lose the buffering function, and the continuous casting machine can only be forced to stop casting as long as the rolling mill breaks down, so that the number of continuous drawing furnaces is reduced, and the production cost is increased;

(2) because no good method for processing the clamped blank on line exists, only the post-casting treatment can be stopped. The chute of the continuous casting machine is positioned below the swing shear, the surrounding space is limited, the difficulty in processing the clamped blank is high, the time is long, and the operation rate of the casting machine is reduced;

(3) the operation space around the chute is narrow and small, and the card base is in hot state and unstable state, and when the worker handled the card base accident, the safety risk was great.
