In order to solve the above technical problems, mortar to be cut includes online returns the present invention provides a kind of mortar cutting method
Receive mortar and offline new mortar；The online recycling mortar and offline new mortar ratio are as follows: the content of online recycling mortar is
78%-85%, offline new mortar are 15%-22%；
The following steps are included:
(a) determine that on-site cutting platform speed, control cutting bed speed are 0.2-0.8mm/min；
(b) steel wire tension is controlled to adjust, laying tension 21N, takeup tension 15N are made；
(c) steel wire linear speed is controlled to adjust, steel wire linear speed 680-890m/min is made；
(d) mortar flow is controlled to adjust, mortar flow 90-130L/min is made；
(e) technological temperature is controlled to adjust, makes temperature at 20 DEG C -25 DEG C；
(f) online recycling mortar mixed proportion is controlled to adjust, is using the content of online recycling mortar in live board
78%-85%；
(g) offline new mortar mixed proportion is controlled to adjust, magnitude of recruitment is 15%-22% using the content of offline new mortar,
It cuts two knives with 400-420kg to use, waste mortar is normally into online recycling system.
Further, the D50 value control of the online recycling mortar is 8.8um-10.3um, and the D50 value is 8.8um-
The concentration angle value of the online recycling mortar of 10.3um is 88.3%-91.3%.
Further, new silicon carbide and old silicon carbide ratios are 2:8 in offline new mortar in the step (g).
Further, new cutting liquid and old cutting liquid proportional are 1:9 in offline new mortar in the step (g).
Further, the viscosity of the mortar is 195-220mpas.
Further, pure online mortar is used using 480-550KG partial application mode in the method, waste mortar normally into
Online recycling system.
Beneficial effects of the present invention: with such a structure: reducing fresh sand and recycling sand usage amount and magnitude of recruitment, directly
Effect is that mortar cost minimizes in abrasive wire sawing；It is more uniform after carborundum granularity abrasion after two knives of offline new mortar cutting,
Also closer to the granularity of pure online mortar, so that it is useless etc. bad preferably to reduce stria, TTV, TTV that granularity unevenness generates；
Offline new mortar for unstable board use can solve with the problems such as improvement steel wire quality, unit exception caused by quality it is different
Often；The use of pure online mortar can monitor in time declines caused stria with silicon carbide out of roundness in prevention mortar.
Specific embodiment
Embodiment provides a kind of mortar cutting method, and mortar to be cut includes online recycling mortar and offline new mortar；
The online recycling mortar and offline new mortar ratio are as follows: the content of online recycling mortar is 78%-85%, and offline new mortar is
15%-22%；
The following steps are included:
(a) determine that on-site cutting platform speed, control cutting bed speed are 0.2-0.8mm/min；
(b) steel wire tension is controlled to adjust, laying tension 21N, takeup tension 15N are made；
(c) steel wire linear speed is controlled to adjust, steel wire linear speed 680-890m/min is made；
(d) mortar flow is controlled to adjust, mortar flow 90-130L/min is made；
(e) technological temperature is controlled to adjust, makes temperature at 20 DEG C -25 DEG C；
(f) online recycling mortar mixed proportion is controlled to adjust, is using the content of online recycling mortar in live board
78%-85%；
(g) offline new mortar mixed proportion is controlled to adjust, magnitude of recruitment is 15%-22% using the content of offline new mortar,
It cuts two knives with 400-420kg to use, waste mortar is normally into online recycling system.
The present embodiment is preferred, since each type useful load is different, below by taking PV800 type as an example.
The present embodiment is preferred, and offline new mortar is continuously cut two knife modes and used using 400-420KG, waste mortar normally into
Line recovery system.
The present embodiment is preferred, and pure online mortar is used using 480-550KG partial application mode, and waste mortar is normally returned into online
Receipts system.
The present embodiment is preferred, new and old silicon carbide ratios=2:8 in offline new mortar.
The present embodiment is preferred, new and old cutting liquid proportional=1:9 in offline new mortar.
The present embodiment is preferred, the offline new mortar board number of overall control: pure online mortar machine number of units=1:4.
The present embodiment is preferred, odd-numbered day offline new mortar dosage: pure online mortar=1:7.
Such as: 8 PV800 equipment cuttings of setting, wherein two equipment are cut using offline new mortar 420kg/2 knife
It cuts, remaining 6 equipment is cut using pure online 480kg/ knife；Wherein pv01# and pv02# uses offline new mortar cutting two
Knife, pv03# to pv08# use pure online mortar, and pv03# shows edge of a knife stria, and pure online mortar is switched to offline new mortar
The cutting of 420kg/2 knife；It is pure online mortar that pv01#/pv02#, which arbitrarily switches an equipment changing,；Pv03-pv05# shows knife
Mouth line trace, at the same switch the pure online mortar of pv03-pv05 using offline new mortar (offline the new mortar board upper limit 3, retain one
Liang Tai is switched back into after it), pv01/pv02 is switched to pure online mortar simultaneously.
Working process and principle:
Abrasive wire sawing polysilicon principle is to run at high speed that mortar particle is driven to grind polysilicon with tensioned steel wire
Mill, wherein the chipping qualities overwhelming majority depends on mortar quality and steel wire quality, and mortar quality depends on mortar out of roundness, and
Out of roundness can be embodied by following parameter: D50 value range 8.8-10.3um, and concentration angle value is 88.3%-91.3%, little particle
No more than 3%, bulky grain is not more than 4.2 no more than 0.2%, PH, and conductivity is not more than 30, and viscosity 195-220mpa.s contains
Water rate is no more than 1.0%, the offline new mortar of proterotype single use and pure online mortar mixed configuration mortar, therein offline new
Mortar is the integral cutting ability for improving mortar.
The new model this time proposed is that offline new mortar and pure online mortar are split use, since offline in proterotype
The effect of new mortar is to supplement mortar cutting force, using this characteristic, to can choose use it has proved that its cutting power is extremely strong
A certain amount of offline fresh sand continuously cuts two knives, and pure online mortar cutting force deficiency can then increase usage amount reduction silicon powder content
It makes up, to reach identical cutting effect.
