Subject; Ind Electric furnaces The details in respect of our requirement is an under {MELTING FURNACE & ANNEALING FURNACE} A} Working chamber dimension {BOX TYPE} HAVING HOT ZONE AREA 300 mm x W x 300 mm H x 450 D B} Temperature cycles involved in respect of malting / Annealing is 2000 c C} During Annealing process whether a Ramp / Soak control is desired to decide this you are the best judge as should be kept in mind that after malting of quartz mineral of purity 99.5% the impurity like" gas inclusion " may not interrupt the annealing process therefore it is you to decide whether a Ramp / Soak control is required either at normal atmospheric pressure or at some particular pressure D} Proposed loading pot martial to hold the material in side the furnace during the process of annealing / malting is crucible of graphite material or other suitable material which you know better as the melting of graphite crucible is approximately 4000c which can be suitable for the entire process it should also be ensured that quartz mineral during the either process shall not strict to the walls of the loading pot material the approximately size of the loading pot material in graphite crucible is outer size 11 x 12 x 17 ' and inner size 7 x 10 x 13 ' i.e. 1/ 2 to 2' through outness of the loading pot material made up of graphite crucible or any suitable size 300 mm w x 300 mm H x450 mm D Regarding the types of control is you are to best judge you quite you rates along with all types of controls and their merits & demerits you are well conversant with the fact that we are interested in manufacturing the quartz plates for electronic use { 99 %} pure grade without any gas inclusion / voids and any other impurity to keep this purity in tact i.e. {99 .5 %} please ensure that the entire pores shall be performed either in vacuum or at normal atmospheericpressure or in liquid nitrogen in the furnaces please .
