Carbon, graphite/steel composite lifting tooling used for high-temperature furnaces

Abstract

The invention discloses carbon, graphite / steel composite lifting tooling used for high-temperature furnaces, comprising a base, a heat-resistant steel cap frame, a graphite sheet frame, a graphite beam and a plurality of heat-resistant steel hooks, wherein, the base is composed of a heat-resistant steel bottom sheet and a low-density carbon / carbon composite sheet which is spread and fixed on the upper surface of the heat-resistant steel bottom sheet; the heat-resistant steel cap frame is fixed right above the base by being supported by a plurality of heat-resistant steel columns; the graphitesheet frame is arranged beneath the heat-resistant steel cap frame like a cushion; the graphite beam is positioned on the heat-resistant steel cap frame and is used for hanging the treated heater products in the high-temperature furnaces; the heat-resistant steel hooks are positioned above the graphite beam; the heat-resistant steel columns are fixed on the base; graphite tubes are sleeved outside the heat-resistant steel columns, and a plurality of graphite hanging structures are correspondingly arranged on the graphite beam. The tooling is simple in structure, convenient in assembly, low inmanufacturing cost, easy in use and operation and wide in application temperature range, and can effectively solve the practical problem that the existing carbon / carbon composite lifting tooling is inconvenient in operation, poor in performance, high in manufacturing cost and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal field materials for high-temperature furnaces, and in particular relates to a carbon, graphite / steel composite hanger tooling for high-temperature furnaces. Background technique [0002] Carbon / carbon composite material has excellent characteristics such as light weight, high damage tolerance, good friction characteristics, long service life, and good thermal shock resistance. It is currently the only engineering material that can withstand high temperatures above 2000 ° C and has been widely used in It has become one of the irreplaceable important materials in carbon brake discs of military and civilian aircraft, missile end caps, throat linings and expansion sections of solid rocket motors, and outlet cones of liquid rocket motors. [0003] However, carbon / carbon composite materials need to be processed in a high-temperature furnace at 800-1200 °C in chemical vapor infiltration (CVI), densificat...
