Description
Technical field
The utility model relates to a kind of continuous casting forming process equipment for metal, relates in particular to the continuous casting forming process equipment for steel.
Background technology
Existing steel mill has substantially all adopted continuous casting technique (continuous casting process) after refining.Continuous casting process is conticaster cast for liquid steel that refining is obtained, condensation, cutting and directly obtain the technique of steel billet.During cast, the ladle that molten steel is housed is transported to the top of conticaster by ladle toter, steel outlet hole through ladle bottom is injected into molten steel in tundish, open after stopper rod of tundish (or slide gate nozzle), molten steel flow in the crystallizer of end opening by dummy head obstruction energy up-down vibration, molten steel is condensed into base shell along crystallizer periphery, when there is certain thickness in exit, crystallizer lower end, with the liquid heart and and the steel billet that connects together of dummy device under Blank drawing machine drives, leave crystallizer and move down along the nip rolls support by arc shooting.Meanwhile, steel billet is further cooling and continue to solidify by secondary cooling apparatus.After dummy device enters withdrawal straightening machine, slough dummy device, steel billet all solidify or with liquid heart state under aligned.At horizontal level, be cut into subsequently the steel billet of certain size.
Steel billet is the semi-finished product of producing the finished product stockings such as shaped steel, Strip and steel pipe.
In order to save the energy, thereby enhance productivity, bring larger economic benefit for enterprise, there are at present some steel mills to adopt or wish to adopt direct hot charging hot rolling technology (DHCR, Direct Hot Charge Rolling), it is by submitting to and change " accurate streamline " formula way of submission in batches by the slab way of submission between casting.Adopted after DHCR technique, logistics becomes solid-state slab by liquid molten steel between steel smelting-continuous casting-rolling line, then after heating rolling, becomes solid-state coil of strip.
Although some steel mills have realized DHCR, but for the product that need to adopt die forging or roll forging processing, remain first and produce steel billet by continuous casting process at present, afterwards steel blank delivered to by the gross or first after warehouse-in, delivered to by the gross stamping room again or roll forging workshop processes.This operation just makes when steel blank is carried out to die forging or roll forging, also to need to carry out the techniques such as blanking, heating, base, that is to say, it need to again heat steel blank after continuous casting process, therefore make energy consumption increase, and increased freight, and make the production cycle elongated, improved the production cost of factory.
In addition, for the production of seamless steel pipe, current processing technology is generally that pipe is cut through cutting machine, then sends into heating in smelting furnace, and in smelting furnace, heating-up temperature is approximately 1200 degrees Celsius.Pipe is come out of the stove and is worn sky by excess pressure punch.After perforation, pipe, just successively by roller trio skew rolling, tandem rolling or extruding, takes off pipe sizing after extruding, and sizing mill proceeds to steel billet punching by taper bit high-speed rotary and forms steel pipe.
Equally, the techniques such as the production technology of above-mentioned traditional seamless steel pipe just makes also to need to cut before pipe is bored a hole, heating, that is to say, it need to cut pipe and need to again heat after continuous casting process, therefore make energy consumption increase, and increased freight, and made the production cycle elongated, improved the production cost of factory.
