Description
Technical Field
The invention belongs to the field of ferrous metallurgy continuous casting machines, and relates to a device for preventing a casting blank from falling down and jacking.
Background
In the production process of iron and steel enterprises, the stability and the production efficiency of a continuous casting machine are important indexes of the enterprises. Therefore, the full-flow production and the drawing speed full load of the continuous casting machine are always the key points of attention of steel enterprises. A series of limiting links such as water quantity, billet discharging capacity, production rhythm and the like are continuously developed during the drawing speed production of the continuous casting machine. In the third steel plant of the mid-day steel, the following step of limiting the drawing speed appears, and when the ML08AL ZT195 SAE series low-carbon steel is produced, because the casting blank is soft, the fracture of the steel blank can sag instantly at the moment the steel blank is cut by a flame cutting machine. Because the span of the front cutting roller way and the rear cutting roller way of the continuous casting machine is large, the casting blank is propped against the rear cutting roller way, and the flow blockage of the casting machine can be caused if the operation is improper. Even steel overflow of the crystallizer can be caused, and a large amount of molten steel can flow on a platform of the casting machine under the condition that the steel flow is not closed timely, so that the problem is not only a link of limiting the pulling speed to be increased, but also potential safety hazards of equipment;
in conclusion, how to overcome the problem that when a traditional flame cutting machine cuts a steel billet, the fracture instantly drops to push the billet becomes a problem which needs to be solved urgently by researchers of the company.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the problem that when a traditional flame cutting machine cuts off a steel billet, a fracture instantly drops to push the billet is solved;
in order to solve the technical problems, the invention adopts the following technical scheme:
the invention relates to a device for preventing a casting blank from falling down and jacking, which comprises: the billet is arranged on the first roller way and the second roller way in a translation way; fire cutter, it includes: the clamping arm is suitable for clamping the steel billet and translating along with the steel billet; the cutting gun is fixedly connected with the clamping arm, and the cutting gun is suitable for cutting the steel billet when being fired; when the clamping arm does not clamp the steel billet, the translation trolley drives the clamping arm and the cutting gun to move, and the moving direction is opposite to the moving direction of the steel billet;
how the device operates, the invention adopts the following steps:
s1: when the steel billet moves from the first roller way to the second roller way, the clamping arm clamps the steel billet, the cutting torch moves along with the steel billet, and the cutting torch is fired at the moment;
s2: when the cutting gun moves to the position above the second roller way, the steel billet is cut off, and the section of the steel billet is supported on the second roller way;
s3: after the steel billet is cut, the clamping arm is loosened, and the translation trolley drives the steel billet to move and clamp the steel billet to another steel billet.
The invention has the beneficial effects that: the invention relates to a device for preventing a casting blank from falling down and ejecting a blank, which can effectively prevent the problem that the casting blank falls down and ejects the blank at the moment of cutting off the casting blank due to the support of a second roller way by cutting off the blank above the second roller way.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic structural diagram of the present invention, wherein an arrow indicates a moving direction of a steel billet;
in the figure: 1-billet, 2-flame cutting machine, 3-first roller way, 4-second roller way, 5-clamping arm, 6-cutting gun and 7-translation trolley.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, the present invention is a device for preventing a cast slab from falling down and ejecting the slab, comprising: the billet 1 is arranged on the first roller way 3 and the second roller way 4 in a translation way; fire cutter 2, it includes: a clamping arm 5 adapted to clamp the billet 1 and to follow the billet 1 in translation; the cutting torch 6 is fixedly connected with the clamping arm 5, and the cutting torch 6 is fired to cut the billet 1; the translation trolley 7 drives the clamping arm 5 and the cutting torch 6 to move when the clamping arm 5 does not clamp the steel billet 1, and the moving direction is opposite to that of the steel billet 1;
how the device operates, the invention adopts the following steps:
s1: when the steel billet 1 moves from the first roller way 3 to the second roller way 4, the clamping arm 5 clamps the steel billet 1, the cutting torch 6 moves along with the steel billet 1, and at the moment, the cutting torch 6 is fired;
s2: when the cutting gun 6 moves to the position above the second roller way 4, the billet 1 is cut off, and the section of the billet 1 is supported on the second roller way 4;
s3: after the billet 1 is cut, the clamping arm 5 is loosened and is driven by the translation trolley 7 to move and clamp to another billet 1.
As shown in figure 1, the flame cutter receives a cutting start signal from a cutting start position A, the clamping arm of the flame cutter is clamped on the billet through the transmission of the air cylinder, and the flame cutter moves forwards together with the casting blank, and the cutting gun also starts to fire and swings to the right side to start cutting the billet. The traditional flame cutting machine generally takes the cutting of a casting blank as a signal for the automatic return of a clamping arm released by the flame cutting machine at a blank cutting terminal position B. Meanwhile, the maximum stroke of the large car of the originally designed fire cutting machine cannot exceed the blank cutting end point B (provided with a rail pile head) of the original design; this is novel just under the unchangeable condition of original design cutting base terminal point position 2, does the adjustment with the maximum stroke of flame cut machine, cuts base terminal point position C department with the adjustment of maximum stroke, and C department is located directly over the second roll table. The broken casting blank is clamped by the clamping arm of the flame cutting machine to move forward continuously, so that the fracture of the casting blank is smoothly lapped on the second roller way after being cut and returned in a loose manner, and the accident that the fracture falls down to push the blank at the moment of cutting the casting blank is avoided.
The invention relates to a device for preventing a casting blank from falling down and jacking, which can effectively prevent the casting blank from falling down and jacking at the moment of cutting off the casting blank due to the support of a second roller way by cutting off the steel blank above the second roller way, and overcomes the problem that the steel blank is cut off by a traditional flame cutting machine and the blank is pushed down at the moment of fracture.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
