Abstract
A quartz crucible for fusion-casting lanthanide optical glass comprises a crucible body, a refractory material sleeve and a refractory material filled layer, wherein the crucible body is an electric melting crucible. The quartz crucible with simple structure can use defective electric melting crucible as the crucible body, of which the cost is only hundreds yuan, however, the cost of platinum crucible or specially made quartz crucible is more than ten thousand yuan, therefore, cost is greatly reduced. Besides, the influence on product quality caused by platinum crucible is eliminated, and the product performance of lanthanide optical glass is improved.
Description
Technical field
The utility model relates to a kind of device of founding opticglass, particularly founds the device of lanthanide optical glass.
Background technology
Lanthanide optical glass is a kind of colouless optical glass of top grade, in order to guarantee the various optical properties of lanthanide optical glass, requirement is forbidden to introduce colored particles such as iron, nickel, manganese in the process of founding, so the selection of the raw material of lanthanide optical glass, melting equipment and machine equipment is all had relatively high expectations.Because the glass melting temperature of lanthanide optical glass generally adopts platinum as crucible body material in the industry generally at 1200-1400 ℃ high temperature, but, can influence the transmitance of opticglass because the trace of the platinum particles of platinum crucible is introduced, and the equipment cost costliness; Also have some producers to use the special quartz crucible of ad hoc structure, thickness to be crucible body material, its device fabrication cost is equally very expensive.Expensive equipment cost has seriously restricted the development of high-grade lanthanide optical glass.
The utility model content
The utility model provides a kind of quartz crucible of founding lanthanide optical glass, can not pollute glass, the transmitance height of glass, and cheap for manufacturing cost.
A kind of quartz crucible of founding lanthanide optical glass comprises the crucible body, refractory sleeve, and the refractory materials packing layer, described crucible body is the electroquartz crucible.
The height of described refractory sleeve is lower than the height of crucible body.
The utility model can use substandard products electroquartz crucible to make the crucible body, and cost only needs hundreds of unit, and platinum crucible or special quartz crucible cost need units up to ten thousand, and cost is greatly reduced.Also eliminated the influence of platinum crucible, improved the product performance of lanthanide optical glass quality product.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Quartz crucible can use below 1450 degree, found the special quartz crucible market price units up to ten thousand of opticglass, the quartz crucible market value of manufacture order crystal silicon is in thousand yuan, and structure of the present utility model can be used substandard products electroquartz crucible, and its market price is hundreds of unit only.The utility model structure has refractory sleeve 3 in the outside of crucible body 1 as shown in Figure 1, has filled up refractory materials 2 between crucible body 1 and the refractory sleeve 3.
Because the hot hardness of quartz crucible self is bigger, the thickness that supports the sleeve matrix of crucible body can be reduced to 1/2 of original thickness, the sidewall height of sleeve matrix also is reduced to 1/3 of former height, make telescopic weight about 1/3 before being, greatly reduce the consumption of bush material, because the reduction of sleeve matrix sidewall height, quartz crucible directly contacts the radiations heat energy in the burner hearth, it is more even to be heated, in the quickeningization material, reduced the corrosion of raw material, the production life-span of quartz crucible is improved greatly, reduced to produce consuming quartzy crucible.
Claims (2)
1. quartz crucible of founding lanthanide optical glass is characterized in that: comprise the crucible body, and refractory sleeve, the refractory materials packing layer, described crucible body is the electroquartz crucible.
2. the quartz crucible of founding lanthanide optical glass according to claim 1 is characterized in that: the height of described refractory sleeve is lower than the height of crucible body.
