Description
Technical field
The present invention relates to a lifting finger, be specially adapted to the buffer unit setting in the hot charging and hot rolling of continuous casting slab technology.
Background technology
Hot Delivery and Hot Charging of Continuous Casting Slab is meant that qualified continuous casting billet that steel mill produces without cooling, do not put in storage, directly is transported in the heater for rolling steel, through rolling process after the post bake.It is the new technology that in recent years promotes the use, be that iron and steel enterprise makes every effort to energy-saving and cost-reducing and new technology that grow up, it organically couples together steel-making in the iron and steel enterprise and steel rolling process, shorten the production cycle of metal logistics flow process widely, energy-saving and cost-reducing significantly, reduce metal consumption, reduce production costs, and be put into the technology of country " 95 " emphasis encourage growth.The producer of domestic employing hot delivery and hot charging has fully experienced the considerable economic that hot delivery and hot charging brings.At present, the level of application of hot charging and hot rolling of continuous casting slab and Direct Rolling Technology has become the new technology index of weighing the iron and steel production technology level, this technology has promoted the integrated of steel-smelting continuous casting-steel rolling production, has quickened iron and steel production and has developed to high-speed, high-quality, low-cost direction.The hot delivery and hot charging method has two kinds usually: roller-way transportation and thermal car transportation.Generally speaking, two factories when not hindering the building of transportation on the rectilinear direction, adopt the roller-way transportation at a distance of in 1 kilometer.Distance use thermal car.
In the hot delivery and hot charging technology that adopts the roller-way transportation, its capital equipment by cross sliding machine, organize rollgang more, change steel machine, elevator, machine for moving steel, buffer unit, cold charge stand etc. and form.Buffer unit is one of visual plant in the hot delivery and hot charging technology.When a cover conticaster and a cover milling train when linking to each other, the effect of buffer unit is to work as conticaster and the milling train hourly output does not play regulating action simultaneously, and when milling train stops because of accident or roll change the store heat steel billet so that the unlikely interruption of hot delivery and hot charging.When two cover conticasters link to each other with a cover milling train, two buffer units must be set in the hot delivery and hot charging technology, above-mentioned effect is not only arranged, also can realize two cover conticasters simultaneously to a milling train heat supply base, and not mix grade of steel.Because it generally is the one heat steel base that high temperature billet steel stores at buffering area, stops about 30 minutes.Therefore, produced the solid matter high temperature billet steel first root steel billet, scrapped problem and produce distortion because the interior outside temperature difference is big.This is particularly important with the hot delivery and hot charging technology that a cover milling train links to each other to two cover conticasters, because each stove steel capital needs to store at buffering area, if every stove steel capital has a steel billet to scrap because of distortion, this is that hot delivery and hot charging technology institute is unallowed, therefore addresses this problem to become to solve the key that adopts hot delivery and hot charging technology when two cover conticasters link to each other with a cover milling train.
Solve the solid matter high temperature billet steel first root steel billet because the interior outside temperature difference is big, scrap problem, three kinds of methods can be arranged and produce distortion:
1, outside heating is because first steel billet distortion of solid matter high temperature billet steel causes greatly owing to the interior outside temperature difference.Therefore, can be to the outside of catching a cold heating, keep in the steel billet outside temperature difference consistent and do not produce distortion.But because the position of first steel billet of solid matter high temperature billet steel is uncertain, hot spot must can move, and is difficult to realization, and heats and also can consume a large amount of energy, and therefore, this method is infeasible.
2, increase external force and force aligning, can increase by a cover mechanism, produce distortion to stop steel billet, but, be difficult to realize because the position of first steel billet of solid matter high temperature billet steel is uncertain, and the mechanism that is increased must be able to move in the outside that steel billet is caught a cold.
3, first steel billet constantly overturn, the method generally has two kinds of modes.
1) the step-by-step movement turn over cooling bed mode of existing comparative maturity, promptly adopt fixed bed, the walking beam assembling, the step-by-step movement transmission mechanism combines with the pusher structure, wherein the moving rail of walking beam fit on adopts tooth-like, after the pusher structure pushes the fixed bed return with steel billet, the motion of step-by-step movement transmission mechanism drives the tooth-like moving rail of walking beam fit on and does the planar circumferential motion, hold up the steel billet on the fixed bed, tooth-like moving tread plays first steel billet and makes the steel billet upset, its steel billet upset probability maximum 50%, because moving rail profile of tooth is to decide according to width of steel billet, in case the steel billet distortion is uncertain, and profile of tooth can't change, the upset probability is reduced greatly, and make and when can turn over steel and become uncertain, therefore can't solve the steel problem of regularly turning over.
2) increase by a cover mechanism and solve first steel billet turning problem, make the steel billet upset no matter whether steel billet is out of shape to force.Advance the steel time interval and only have 1.5 minutes because technological requirement pushes away steel for twice, deduct and push away steel and return the cylinder time and only have more than 50 second.And because first steel billet position be uncertain, mechanism must move with first steel billet, and finishes first steel billet and constantly overturn, and is difficult to design one cover mechanism and finishes this turn over the steel action in short time like this, therefore, is difficult to realize.
Summary of the invention
The present invention is the third mode, first steel billet problem on deformation when its purpose solves the storage of solid matter high temperature billet steel exactly, at buffering area buffer unit is designed to lifting finger, lifting finger adopts the pusher structure to combine with fixed bed, walking beam assembling, step-by-step movement transmission mechanism.Be provided with the step of dark 100mm, a long 250mm in the ejection position of fixed bed track, the pusher structure turns over along the fixed bed track steel billet and turn 90 degrees to step to the step position.The step-by-step movement transmission mechanism drives the eccentric wheel rotation, makes the walking beam on the eccentric wheel assemble rising and do translational motion along circumference, and the steel billet that holds up on the fixed bed moves a step pitch backward, and first steel billet is displaced downwardly on the step from the fixed bed step.Advance steel pusher structure next time and move once more first steel billet turn under the step, thereby realize first steel billet circulation of solid matter high temperature billet steel upset.This invention has solved in the hot charging and hot rolling of continuous casting slab technology, and the solid matter high temperature billet steel is when buffering area is incubated, and first steel billet problem on deformation satisfies the hot charging and hot rolling of continuous casting slab technological requirement, and it is simple in structure, convenient and reliable operation, economic benefit and obvious social benefit.
