Carbon/carbon composite material lifting appliance for high-temperature furnace

Abstract

The invention discloses a carbon / carbon composite material lifting appliance for a high-temperature furnace, which comprises a bearing chassis, a plurality of borne lifting rods and a plurality of annular plates, wherein the borne lifting rods are distributed on the bearing chassis along the circumference direction; the annular plates are respectively used for fixing the borne lifting rods and are distributed in the horizontal direction; the annular plates and the bearing chassis are firmly connected with the borne lifting rods respectively by a fastening device I and a fastening device II; and the borne lifting rods, the bearing chassis, the annular plates, the fastening device I and the fastening device II are made of a carbon / carbon composite material and commonly form an integral type lifting appliance which can carry out heat treatment with a treated product under the temperature condition of 1,500-3,000 DEG C. The invention has the advantages of simple structure, good use effect, safe and reliable working performance and long service life, is convenient for assembly and simple and convenient for operation, and can solve the problems that the traditional lifting appliance for a high-temperature furnace can not be subjected to high-temperature treatment process together with the treated product and needs an operator to lift the product in the furnace, the labor condition is poor, the safety is low, and the like.

Description

technical field [0001] The invention belongs to the technical field of high-temperature treatment production process equipment for carbon / carbon composite materials and graphite materials, and in particular relates to a carbon / carbon composite material hanger for high-temperature furnaces. Background technique [0002] At present, when preparing carbon / carbon composite materials, graphite materials, etc., the working temperature of the high-temperature treatment furnace used is mostly in the range of 1500°C to 3000°C. There is no special high-temperature-resistant hanger when the products are loaded out of the furnace, and ordinary steel can only be used first. Lift the product into the furnace with a spreader, and then the operator goes into the furnace to unload the product, and then lifts the spreader out of the furnace; when the furnace is released, the operator also needs to go down into the furnace to load the product into the spreader and lift it out of the furnace.
