[0001] The invention relates to the technical field of mechanical cutting of steel billets in a metallurgical process, and in particular to a double-station automatic steel billet cutting system and a use method thereof. Background Art

[0002] Billets are products obtained by casting molten steel from a steelmaking furnace. The general specifications are: length: 3700-12000mm, width: 880-2200mm, thickness: 150-240mm. During the production process, steel mills will produce a large number of scrap billets, and the treatment of these billets has always been a problem for steel mills; because the energy medium (oxygen, natural gas or acetylene, etc.) capacity of traditional steel plate flame cutting machines is small, and the cutting gun can only move horizontally but not up and down, it is only suitable for cutting thin plates (10mm-50mm) and is not suitable for cutting steel plates with a thickness greater than 100mm. Therefore, most steel mills currently use manual handheld cutting guns for cutting. At the same time, due to the thick thickness of the billet, flame cutting requires a long time of preheating, oxygen blowing and oxidation, which requires a lot of manpower and has low production efficiency; and a large amount of smoke is generated during the cutting process, causing serious environmental pollution.

[0039] The embodiment of the present invention further discloses a method for using a dual-station steel billet automatic cutting system, comprising:

[0040] (1) Check that all systems are intact and prepare to start cutting;

[0041] (2) The cutting machine body is in the initial position (the billet cutting table I standby position), and the large frame is not moving;

[0042] (3) The crane hoists the scrap steel billet onto the steel billet cutting table I, and adjusts the steel billet placement angle through the crane suction cup so that the steel billet placement direction is parallel to the steel billet cutting table;

[0043] (4) The billet cutting machine is started, the large frame starts to move, and the billet appears in the field of vision through the camera;

[0044] (5) Press the "Automatic Cutting Start" button, and the large frame will automatically move according to the set cross-cutting spacing and stop after reaching the specified distance;

[0045] (6) At this time, the laser rangefinder on the top of the large frame detects the distance between the upper surface of the steel billet and the detection point, and then (backstage) calculates the distance between the cutting gun (in the initial position) and the upper surface of the steel billet, which is the cutting gun descent stroke;

[0046] (7) After the cutting gun descends to the calculated stroke, it starts to move horizontally. The laser rangefinder installed on the upper part of the cutting gun bracket detects the thickness of the steel billet and stops when it reaches the edge of the steel billet. The combustion medium is ejected through the cutting gun and starts to ignite and burn, preheating the edge of the steel billet.

[0047] (8) The cutting gun starts cutting, and the transverse transmission device moves according to the cutting speed of the steel billet of different thicknesses input inside the system until the steel billet is completely cut transversely, and then the cutting gun returns to the horizontal initial position;

[0048] (9) The large frame continues to move, automatically moving according to the set cross-cutting spacing to reach the next cutting position;

[0049] (10) The cutting gun starts to move horizontally, and starts cutting after reaching the edge of the billet until the horizontal cutting is completed;

[0050] (11) Repeat steps (9) and (10) until the waste blank is cut;

[0051] (12) Enter the standby position of billet cutting station II and cut the scrap billet at billet cutting station II according to the above operation sequence; at this time, the driving suction cup lifts the scrap billet at billet cutting station I away;

[0052] (13) After the waste billet cutting station II has finished cutting, return to the waiting position of the billet cutting station II;

[0053] (14) The crane suction cup lifts the scrap steel billet from the cutting platform of steel billet cutting table II;

[0054] (15) When there is no scrap billet on the billet cutting table I, the billet cutting table I must first return to the waiting position, and the operation is cyclic.

[0055] In summary, the method for using a dual-station automatic billet cutting system disclosed in an embodiment of the present invention has the advantages of easy operation and improved efficiency: the billet can be cut in the form of reciprocating cutting by two billet cutting tables, thereby improving the cutting efficiency.
