Abstract
High-pressure high-temperature presses are commonly employed to create superhard materials used in such fields as road milling, mining and trenching, to breakup tough materials such as asphalt, concrete and rock. Many such presses comprise a plurality of piston assemblies that may act in concert to pressurize a cell. Such a cell may comprise a body with a plurality of canisters disposed therein and at least one unique heater element adjacent each of the canisters. Heat may be generated within such a press by forming an electrical circuit with the unique heater element and anvils surrounding the cell.
Claims17
A cell for a high-pressure high-temperature press, comprising:
- a body with a plurality of canisters disposed therein;
- at least one heater element adjacent each particular canister for individually heating each particular canister;
- and
- at least two electrical circuits each passing through at least one different heater element.
