Material process.
Background technique
In recent years, with the keen competition and development in photovoltaic market, manufacturing optical material at low cost becomes each
The target of a optical material manufacturer.Therefore, in two kinds of production methods of optical glass production, the higher single crucible of production cost
Production method is phased out.And have production cost is low widely to be sent out with the big tank furnace continuous production mode of glass throughput
Exhibition.But for the optical glass of some high melting temperatures and high refractive index, the melting efficiency that tank furnace continuously melts is very low, and
The product refractive index fluctuation of production is very big.In order to improve the continuous production ability of tank furnace, the mode of stock is generallyd use to solve
Above-mentioned problem.Optical glass batch fritting is namely prepared into glass clinker, then secondary smelting is carried out to clinker.By optics
The process that glass batch prepares into glass clinker is known as stocking up, and feed preparing device is the key equipment of optical glass melting process.
The feed preparing device that optical glass industry uses at present is common single crucible melting device, and production method is using casting
Or leakage note.It but no matter is all that raw material are added in crucible after melting, clarification, homogenizing using any mode, then by glass pouring
Note is prepared into optical glass clinker after releasing by vomit pipe, then will the standby clinker of institute mix after carry out using.But these
Feed preparing device has the shortcomings that common, that is, the low efficiency of stock, and standby glass clinker refractive index fluctuation it is big.
