Description
Technical field
The present invention relates to metallurgical steel rolling equipment technical field, in particular to a kind of scale breading withdrawal straightening machine.
Background technique
The raw material of cold-strip steel is hot-rolled coil, and the strip rolled out under high temperature can not be kept away in cooling and coiling process
That exempts from generates iron scale on belt steel surface.The presence of iron scale will affect the surface quality of cold-strip steel, influence cold
The quality of strip subsequent product processing is rolled, so before carrying out cold rolling processing to strip, it is necessary to by strip on special production line
Iron scale on surface is disposed.Current widely used hot rolled steel plate de-scaling line is to have sulfuric acid or chlorohydric acid pickling medium
Producing line is commonly called as strip pickling line.This producing line is mainstream production line currently on the market, and most important process procedure is mechanical
It scale breading and is electrochemically reacted in descaling bath using acid solution and iron scale.Mechanical scale breading link is to allow strip before pickling
By scale breading withdrawal straightening machine, keep belt steel surface iron scale loose, to accelerate the speed of chemical de-scaling, pickling speed can be improved
20%.Existing mainstream scale breading withdrawal straightening machine is full-closed structure, inside sets compressed-air atomizer purging belt steel surface, peripheral hardware dust removing tube
The iron scale of purging is drawn onto cleaning shaft by road and air draft equipment.Descaling mill ontology includes welding stand, two pairs of bending rolls
Group, one group of aligning roller group, inlet turning roll, two, which put on bending roller group, quickly depresses opening mechanism, the lower bending roller group of three sets of drivings
With the elevating mechanism of lower aligning roll assembly, blow device, dust collecting installation and Quick roll-changing device.It is needed before and after descaling mill
Individual tensioner is set, provides hightension for scale breading straightening process.
But strip pickling line generates spent acid in strip acid cleaning process, national pickling producing line arrangement is more, and yield is big,
A large amount of spent acid generate the harm of especially severe to environment.
It is a kind of especially energy-saving and environment-friendly for eliminating hot rolled plate under the general trend of events that society vigorously advocates industrial energy saving environmental protection
The producing line of belt surface iron scale is come into being.Full utilization physical means clear up strip scale on surface, avoid
The process procedure of pickling is carried out using chemical means such as sulfuric acid or hydrochloric acid.Arranged in producing line uncoiler, coil opener, cutting head cut,
The capital equipments such as descaling mill, level(l)ing machine, wet type shot-peening unit, docking shears, oiler, coiling machine.Environmentally friendly de-scaling producing line is important
Technique is first with descaling mill to the pre- de-scaling of strip, then carries out final de-scaling in wet type shot-peening unit, black plate face is become
For white bright plate face.Scale breading withdrawal straightening machine is the function device of scale breading link very crucial in environmentally friendly de-scaling producing line, to entire
The production of producing line plays a crucial role.
Due to the environmentally friendly not set welding machine of de-scaling producing line, every coiled strip steel needs threading operation.If existing scale breading withdrawal straightening machine
Directly applying in environmental protection removing iron scale producing line can suffer from the drawback that
1, the bending roll system of existing scale breading withdrawal straightening machine is independent is arranged on individual roller seat, each individual roller seat
It is arranged in corresponding framework window, rack width is big, so that every coiled strip steel threading becomes extremely difficult；
2, the working roll horizontal space of the upper and lower bending roller group of existing scale breading withdrawal straightening machine is larger so that rack width compared with
Greatly, it is unfavorable for needing the occasion of frequent threading；
3, in resistance straightening unit, the aligning roller group of two big roller diameter is arranged in above strip, is arranged using fixed form, is replaced
New roller is very laborious time-consuming；
4, existing scale breading withdrawal straightening machine entrance is equipped with special scale breading straightening area's jockey pulley to realize hightension scale breading, if
Standby combination is huge, and weight is big, and input cost is high；
5, higher to the rigidity requirement of descaling mill roller seat because entrance tension is big, so roller seat design size is big, weight
Greatly, at high cost；
6, existing scale breading pulling correcting machine working roller is relatively large in diameter, and is not easy to realize the energy-saving design of macrobending, small tensile stress
Mode；
7, hot-strip generates a large amount of iron scale dust after existing scale breading withdrawal straightening machine carries out scale breading, tradition
Descaling mill designs totally-enclosed dust guard, dust catcher and air draft equipment, increases power of fan.This set mechanism is complicated,
It is easy to interfere with part in rack, cost of investment is high；
It can be seen that being not suitable for if existing scale breading withdrawal straightening machine is directly applied to environmentally friendly de-scaling producing line with very big
Property.Therefore, it is highly desirable a kind of scale breading withdrawal straightening machine that design is suitable for environmentally friendly dephosphorization producing line.
