We always choose good suppliers of hydraulic parts, motors, speed
reducers, electric parts. As well, we like to purchase those parts
according to customer requirements for special metal coil slitter.
In the beginning, the coil is loaded on the coil car by crane and
brought to the uncoiler by operating the coil car. Coil car
centralizes the coil with the uncoiler mandrel and the coil is
mounted on the uncoiler. Mandrel is expanded. Snubber roll rotates
the coil. Peeler breaks the straps and brings the pre end upto
Pinch roll. The Pinch roll drives the coil end upto the slitter.
Then its drive is disconnected. Slitter moves the slitted strips
further. Slitted strips are threaded through loop table and drag
tensioner into the recoiler drum. Recoiler winds one turn on loose
Then drag tensioner and loop are put into operation. Slitter and
recoiler run simultaneously in synchronization. As the coil build
up, the recoiler rpm correspondingly goes down to keep desired
constant line speed. This process goes on until the end of coil on
uncoiler. The slitted coil is pushed on the exit coil car through a
pusher plate operated by hydraulic cylinder. The side slitted scrap
is wound on the scrap winder units provided on both sides of the
Operating Procedure of Stainless Steel Slitting Machine
Preparatory work before steel slitting machine production
1. Before the formal production, the dust and dirt and other
foreign matter on the surface of the equipment and the coil should
be carefully cleaned to keep the equipment and the ground floor and
articles clean. At the same time, all rollers on the guide road
which the strip passes should be carefully cleaned. When necessary,
it needs to be polished with sandpaper and then wiped clean with
alcohol to ensure that the surface of the finished product is free
from scratch and other defects caused by this process.
2. Check the mechanical and electrical system of the steel slitting
equipment according to the equipment inspection table, and operate
the equipment in an empty state to confirm that the equipment is in
a normal and power-on state.
3. Check whether the production card is consistent with the batch
number, alloy status, specification size and weight of the material
coil; According to the quality and acceptance criteria of steel
slitting linemachine, check whether the surface quality and end
face quality of the pending coil meet the needs of production.
Before starting the equipment, the crew must comply with the
requirements for machine maintenance and operation. After carefully
checking all parts of the body, they can send electricity,
otherwise they are not allowed to start the equipment.
4. The blanks and finished products parameters are correctly input
in the control procedures of the main operation console of the
equipment, such as incoming material thickness, incoming width,
finished product width, and finished product length. According to
the width of incoming material and finished product, calculate the
required cutting width and adjust the tool distance. Meanwhile, the
number of pieces per stack is calculated according to the
requirement of production card.
Matters needing attention in production
1. Be careful not to touch the coil when feeding.
2. Manually adjust the coils on the uncoiler. Normally, the coil
must be aligned to ensure that the width of the two cut edges is as
consistent as possible. In special cases, when there is a large
crack or other defect on the side of the material, the width of the
two cutting edge is not consistent, but the horizontal position of
the coil on the uncoiler must be adjusted manually, and it is
confirmed that the edge defect of the blank can be completely
3. Check the thickness and width of incoming material before
production can be carried out.
4. When the material coil with a thickness of more than 0.5mm is
removed from the steel belt, the roller must be used to prevent the
coil from being thrown.
5. The material should be positive when wearing, and the material
should not be crooked or wrinkled. It is strictly prohibited to
wipe the rollers at the entrance to avoid getting involved.
6. In the process of cutting slitting machine steel , when marks
and scratches caused by the machine are found on the surface of the
plate, the guide rollers on the guide road should be stopped and
checked timely. If any prominent particles are found, they should
be polished with sandpaper and then cleaned with alcohol.
7. Pay close attention to the surface quality of incoming materials
during the operation of the machine. According to the requirements
of the quality and acceptance standard of steel slitting
linemachine, if it is found to be unqualified, it must stop the
machine and find relevant technical quality personnel to deal with
8. Before each roll of material is produced, a sheet of material
should be cut, and the production can be carried out in accordance
with the technological requirements of the length and width on the
card. If not, it is necessary to adjust the parameters of scissors,
otherwise it is not allowed to continue production.
9. When lifting the finished products, it is necessary to carefully
inspect the crane and rigging, and command and operate overhead
travelling cranes to concentrate. Operators are prohibited from
standing in small and unsafe places to prevent material from
10. In case of equipment failure in production, stop immediately
and inform the maintenance staff to deal with it.
