Abstract: A purpose is to provide a tray for oil quenching heat treatment furnaces that can inhibit oil infiltration to reduce adverse effects on the quality of the workpiece and also can make lightweight design of the tray possible.Provided is a tray including a carbon material and being capable of placing a workpiece thereon for oil quenching of the workpiece, characterized in that the cumulative pore volume of pores with a pore radius of greater than or equal to 1 μm is less than or equal to 40 mm3/g in the carbon material. The carbon material is desirably such that a C/C composite is impregnated with a thermosetting resin and burned.

Abstract: The present invention improves the strength of the bottom (net) of the jig and makes it more difficult and unlikely for deviation of the mesh to occur.A workpiece is loaded on the net (2) of the heat treat furnace jig (hereinafter, heat treatment furnace jig). In the net (2), a first strand (10), a second strand (20) and a third strand (30) are in contact at a contact point (X1). Near the contact point (X1), the second strand (20) overlaps the first strand (10) from above and the third strand (30) overlaps the first strand (10) from below. As a result, the first strand (10) is held between the second strand (20) and the third strand (30) in the up/down directions.

Abstract: A carbon crucible (1) has a structure including a straight trunk portion (9) and a tray portion (10) vertically separated from each other. The straight trunk portion (9) is made of a carbon fiber-reinforced carbon composite material and the tray portion (10) is made of graphite. An upper end face of the tray portion (9) is provided with a step portion (11) having an outer circumference-side region that is higher relative to an inner circumference-side region thereof. The straight trunk portion (9) is fitted to the step portion (11), and in the straight trunk portion (9) and the step portion (9) that are fitted to each other, a gap is provided between an inner circumferential surface (11a) of the step portion (11) and an outer circumferential surface (9a) of the straight trunk portion (9). The gap is preferably from 0.1% to 1.0% of the diameter of the straight trunk portion.
