TRANSPIRATIONAL FIRST WALL COOLING
20230005627 · 2023-01-05 ·

A first wall structure for a plasma chamber (200). The first wall structure comprises and inner wall (201) and a solid deposit (202). The inner wall is formed from a refractory metal or an alloy or composite thereof and has a plurality of pores. The solid deposit in thermal contact with the inner wall, such that the plurality of pores provide a passage from an exterior of the first wall structure to the deposit. The deposit consists of a material having a boiling point less than a melting point of the refractory metal. The first wall structure is configured such that at a normal operating temperature of the first wall structure, the deposit is solid.

DENSIFICATION METHOD AND APPARATUS

A method of densification of refractory material in a gap between a tap hole sleeve of a furnace and a surround block of the furnace, the surround block surrounding the tap hole sleeve, the method comprising, includes positioning a tool in the gap, the tool including a support having opposing surfaces and a sidewall connecting the opposing surfaces, the opposing surfaces having an arcuate shape, a plurality of elongated members extending from one of the opposing surfaces, and a connector arranged on the other of the opposing surfaces. The gap is filled with dry material, and vibration is applied to the tool to densify the dry material.
