Orton
Model RSV-1600 Series Molten Glass Viscometers
are designed to measure the viscosities of glasses at various
temperatures for ASTM C-965 Procedure A and ISO 7884/2 testing. The
Model RSV-1600 is used to measure viscosities at specific temperatures in
order to generate a curve of the visco-elastic behavior of molten glass,
as shown below.

To
make testing cost effective, Orton designs the system to
accommodate your platinum crucible size. The systems in the
photographs are examples of units that were designed
specifically for the customer's sample crucible size
requirements.
The photo to the left is a 1,600°C, laboratory bench top system
using a platinum crucible approximately 60 mm (2.36”) tall with
a top and bottom OD of 73 mm (2.87”) and 57mm (2.24")
respectively which contains approximately 300
grams of glass.
The photo to the right: The molten glass is held at a
predetermined soak temperature until the thermal equilibrium is
reached, and is monitored by the sample thermocouple at the base
of the crucible, which sends its signal to the digital display in
the UTC console. |
Operation
(Isothermal methods)
|
The Model RSV-1600 System
includes vertical tube furnace (molybdenum disilicide), a type “S” furnace control
thermocouple, a temperature control system with a multi-segment user
programmable PID controller, stepdown transformer (if required), a
crucible support pedestal, a type “S” sample thermocouple, a
Brookfield viscometer, and component support structure.
The crucible is loaded into the system in one of three ways. First, the
crucible is placed on a fixed pedestal support, and the furnace is
lowered over the crucible. Second, the crucible is placed on the
moveable support pedestal, and the pedestal is raised into the fixed
position furnace. And third, the crucible is manually lowered into the
fixed position furnace and rests on the fixed position pedestal support.
The pedestal or furnace movements can be manual or motorized.
It is necessary to lower and raise the spindle into and out of the
molten glass in the crucible. The viscometer is supported above the
furnace, and is normally raised and lowered manually, but can be
motorized.
The entire system is designed around the purchaser’s crucible size,
range of viscosities, component movement method, and budgetary
constraints.
The crucible and spindle can be supplied by Orton, however, since most
glass companies have access to lower cost platinum, most users provide
their own crucibles and spindles.
