Description

Technical Field

[0001] The invention relates to the technical field of flame cutters, and in particular to a flame cutting ignition device for a continuous casting machine steel billet. Background Art

[0002] A continuous casting machine is a metallurgical equipment that continuously transforms liquid steel into solid billets. It has the characteristics of high efficiency, energy saving, and environmental protection. The working principle of a continuous casting machine is achieved through a continuous casting system composed of a mold, a cooling device, a molten steel collection system, and a billet conveying system. The main structures of a continuous casting machine include a billet box, a pouring box, a crystallizer, a support frame, a stretching device, a cutting machine, a conveying device, etc. In a continuous casting machine, steel is melted into molten steel, and the molten steel enters the crystallizer through the pouring box. The surface of the molten steel is cooled by the crystallizer, so that the molten steel quickly condenses to form a billet. The billet moves on the support frame and is stretched by the stretching device. Then, the billet is cut by a cutting machine to obtain a billet of a specified length.

[0003] There are two main cutting methods on the existing continuous casting machine, flame cutting and mechanical cutting. Mechanical cutting is to cut the steel billet by mechanical shears, and its advantage is fast cutting speed. Flame cutting is to melt and cut the steel billet by a flame cutter. The flame cutting equipment is lighter and requires less investment. At the same time, the cut section will not be deformed, and the equipment is easy to maintain. Therefore, the cutting method using a flame cutter is more commonly used. However, the flame cutter remains in a waiting-to-cut state between two cutting stages, and the flamethrower keeps flame spraying at all times in the waiting-to-cut state, which consumes a lot of gas, resulting in a large waste of energy and a large amount of cost losses.

Gear 1 15 drives the welding frame 12 and the welding gun 18 to move through the rack 9, so that the nozzle of the welding gun 18 extends into the sealing hole 23. At this time, the output end of motor 4 28 drives the bidirectional screw 26 to rotate, so that the sealing clamp 25 clamps the welding gun 18 to reduce the air flow in the sealing cabin 3. At this time, the output end of motor 5 30 drives gear 2 29 to rotate, gear 2 29 drives gear 3 31 to rotate, and gear 3 31 drives the cleaning column 33 to slide on the sliding frame 32.
