ABSTRACT:
An apparatus for hot uniaxial pressing of heat resistant metal canisters containing synthetic rock components.
A hydraulic press is provided in a furnace and has a fixed top press frame with refractory top pad and fixed base. The furnace comprises an electrical induction coil with a cylindrical metal sleeve functioning as a susceptor sleeve. The press is also provided with an upwardly acting hydraulic ram with ram head and refractory top pad.
A platen is provided on a ram having a mounting shaft. The ram is actuable to laterally displace the platen so that columns extending on opposed sides of the press and having respective recesses are arranged to engage with complementary portions of the platen.
The susceptor sleeve can be removed by swinging the platen around to extend below the region of the susceptor, but not into engagement with the column recesses, raising the platen and then releasing a clamping mechanism which normally grips the susceptor.
