Abstract
An on-line width adjusting device for a hot rolled strip steel production line comprises a press machine. The on-line width adjusting device for the hot rolled strip steel production line is characterized in that the press machine is arranged between a rough rolling descaling machine and a rough rolling horizontal rolling mill of the hot rolled strip steel production line, and a pair of hammers of the press machine are arranged on the two sides of a continuous casting blank above a conveying roller way. The on-line width adjusting device has the advantages that the width of the continuous casting blank is reduced in a free forging mode, the requirements for the ability of the on-line width adjusting device of the modern production technology can be met, the width reducing quantity can be adjusted, and the adjusting range is obviously larger than that of other on-line width adjusting devices.
Description
Technical field
The invention belongs to technical field of metallurgical equipment, relate in particular to on-line width adjustment equipment in hot-rolled strip production line.
Background technology
Hot continuous rolling production line can be produced the product tape steel of different in width specification by on-line width adjustment equipment, the most common hot continuous rolling on-line width adjustment equipment is that the continuous casting billet that casts out different in width specification by the continuous casting line of hot continuous rolling rolling line upstream is realized the finished strip of producing different in width specification.
In prior art, for reducing continuous casting line width of plate slab specification, improve continuous casting line operating efficiency, reducing wedge shape base ratio, on hot continuous rolling production line, need to take on-line width adjustment means.The wide means of existing tune are to adopt powerful vertical miller.Its deficiency is: vertical miller adjusts wide ability to be subject to the restriction of rolling principle and the equipment limit, and every time maximum subtracts wide amount and only has 100～120mm, can not meet the demand of production technology.
Summary of the invention
The object of this invention is to provide a kind of fixed-width pressure machine, overcome the deficiencies in the prior art.
Technical scheme of the present invention is: hot-rolled strip production line on-line width adjustment equipment, it is characterized in that described fixed-width pressure machine is arranged between hot-rolled strip production line roughing descaler and roughing horizontal mill, a pair of tup of fixed-width pressure machine is placed in the both sides of conveyor roller top continuous casting billet.
Hot-rolled strip production line on-line width adjustment equipment of the present invention, is characterized in that the wide power machine of described compression set is fixed width electrically powered press or fixed width hydraulic press.
Hot-rolled strip production line on-line width adjustment equipment of the present invention, is characterized in that described thickness of strand is 50-250mm, fixed-width pressure machine every time to subtract wide amount be 50-375mm.
The invention has the beneficial effects as follows: in flat-die forging mode, continuous casting billet is subtracted widely, can meet the Capability Requirement of modern production technique to on-line width adjustment equipment; Subtract wide amount adjustable, adjustable range is obviously greater than other on-line width adjustment equipment.
Accompanying drawing explanation
Fig. 1 is hot-rolled strip production line on-line width adjustment apparatus and process floor plan of the present invention.
Fig. 2 hot-rolled strip production line on-line width adjustment of the present invention equipment operation principle schematic diagram.
In figure, 1, the arrow in roughing descaler 2, fixed-width pressure machine 3, conveyor roller 4, roughing mill 5, forcing press tup 6, continuous casting billet Fig. 1 is that in continuous casting billet traffic direction Fig. 2, arrow is the fixed-width pressure machine tup direction of motion
The specific embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
Above continuous casting billet conveyor roller between hot-rolled strip production line roughing descaler 1 and roughing horizontal mill 4, arrange a fixed-width pressure machine 2, a pair of tup 5 of fixed-width pressure machine is placed in respectively continuous casting billet 6 both sides.By electronic or a pair of tup 5 of hydraulic drive mechanism cyclic drive, continuous casting billet 6 being carried out to flat-die forging subtracts wide.Thickness of strand is 150-250mm, and it is 50-375mm that fixed-width pressure machine subtracts wide ability a time.Can take start stop mode or continous way working method subtracting continuous casting billet in wide process.
The effective length that tup 5 each cycles subtract wide extruding to continuous casting billet 6 is at 200～500mm, and tup flat-die forging frequency is at 30～55 beats/min, and it is 2700 tons that maximum subtracts wide power, and concrete numerical value need and subtract wide amount according to the concrete material of continuous casting billet and determine.
