Problems solved by technology
[0007] Similarly, the production process of the above-mentioned traditional seamless steel pipe requires cutting, heating and other processes before the tube blank is pierced, that is to say, it needs to cut the tube blank after the continuous casting process and needs to be heated again, Therefore, the energy consumption is increased, and the transportation cost is increased, and the production cycle is lengthened, which increases the production cost of the factory

Embodiment Construction
[0027] figure 2 is a flowchart of an embodiment of the continuous casting method for metal according to the present invention.
[0028] figure 2 Step S10 in the above represents the steelmaking step, which can be made through electric arc furnace steelmaking mainly using scrap steel as raw material, intermediate frequency electric furnace, etc. It can also be blast furnace rough smelting and refining. For converter steelmaking, secondary metallurgy (also called refining) is preferably performed on the molten steel coming out of the converter. That is to say, the steelmaking step of S10 may refer to only one steelmaking step, or may be a secondary steelmaking step including smelting and refining.
[0029] In the prior art, the liquid steel obtained through the steelmaking step S10 is usually transported to the turntable, and the turntable is rotated to the pouring position to pour molten steel into the tundish. The tundish distributes the molten steel to each crystallizer...

Disclosed is machining equipment for continuous metal casting, comprising: a furnace for conditioning liquid metal to meet the required conditions; a tundish for holding liquid metal conditioned by the furnace; a crystallizer (1) for receiving liquid metal from the tundish and solidifying the liquid metal into a metal blank; a withdrawal and straightening machine (2) for withdrawing the metal blank from the crystallizer and straightening same; a shearing apparatus directly provided downstream of the withdrawal and straightening machine and used to shear the metal blank exiting the withdrawal and straightening machine; and a die forging apparatus or a roll forging apparatus or a perforating apparatus, directly provided downstream of the shearing apparatus, and used to directly perform die forging or roll forging on the sheared metal blank to shape same into a product of the required size and shape, or to perforate the blank to form a seamless tube. The invention also relates to a machining method for continuous metal casting.
Description
technical field [0001] The invention relates to a continuous casting forming processing equipment and method for metal, in particular to a continuous casting forming processing equipment and method for steel. Background technique [0002] The existing steelmaking plants basically adopt the continuous ingot casting process (continuous casting process) after refining. The continuous casting process is a process in which the refined liquid steel is poured, condensed, and cut with a continuous casting machine to directly obtain a billet. When pouring, the ladle containing molten steel is transported to the top of the continuous casting machine through the ladle carrying device, and the molten steel is injected into the tundish through the steel flow hole at the bottom of the ladle, and the tundish stopper (or sliding nozzle) is opened ), the molten steel flows into the crystallizer whose lower opening is blocked by a dummy rod head and can vibrate up and down, and the molten st...
