b is the role of the liquid suspension
Effect c of the steel wire is carried
So cutting principle of Steel Coils Supplier from China
is the integration of silicon carbide cutting fluid at high speed steel wire driven by the completion of the cutting action.
The role of B slurry and the importance of quality control:
a: the role of the slurry is cut, it is cut the body and in the cutting process also plays a certain cooling, cooling, lubrication.
b: The new slurry only by sand and liquid composition, can not have any other debris. In the slurry after use where there Suifen glass, steel scrap, silicon powder, tape, etc. Replace the main control these mortar slurry in proportion less than 7-8%, the only way to ensure the slurry cutting capacity, if the mortar is not configured correctly, or contains a lot of impurities, will lead to jumpers, disconnection, thereby yielding silicon wire marks will appear, color, uneven thickness or even scrapped.
C: Run the machine and cutting process slurry run
NTC MWS is taken under the pressure of the feed. For ingot shape relationships, slurry flow rate must change with ingot shape change, so as to ensure the quality of the silicon wafer surface. On the machine is the use of mortar flow chart manner set and indicated.
D: check items before cutting inside and machine health:
a: steel wire winding conditions (pressure lines, uneven surfaces, etc., and the tension is normal).
b: contact wheel and wear condition and stability of each guide wheel.
c: Is there a jumper, debris on the main roller; steel wire path is correct.
d: Are there pieces, tape and other debris must deal with the main roller clean.
e: each guide wheel and contact wheel is rotating properly balance arm if there is deposition of mortar, whether swing freely.
f: parameter, due to changing the spool and other operating parameters need to be changed must be changed before cutting.
g: nozzles must be cleaned and must be observed that the slurry out of uniform, whether there are segments curtain.
h: the slurry must be filtered before starting the clean slurry can not have debris.
I: ingot whether their nets to avoid climbing phenomenon caused by the slope of the ingot.
j: Check the ingot is locked.
Causes and treatment produced jumper
Damage to a wire slot on the main roller (treatment: good tape posted online online good alignment process).
Debris (treatment on two main roller: Wipe clean the main roll, if not wipe clean with compressed air needs to be the main roll on the bottom of the impurity to blow off, you need to move the cut after a tension wire mesh cut off if necessary after clean up).
3 by the steel wire in the guide wheel is not in the tank, leading to wear of the steel wire, resulting in high linear distortion on the main roll.
(Treatment with 1)
4 cutting debris generated during lead (the same processing method 2) are the main form of jumper.
A one of the main roll has a main roll there.
2 has two main roll is and groove, quit.
3 cross lines, two steel wire slot swap lines cross just cause.
