Problems solved by technology

At present, most of the pallets for special hoisting tools for pit furnaces are disc-shaped integral bottom trays with a fan-shaped material tray structure. Although the structure is flat, it is beneficial to the deformation control of parts in the heat treatment process, but the structure of the disc-shaped integral support is complex and large in size. , many casting defects and low service life

Abstract

The present invention discloses a vertical pit furnace bracket type tray, which comprises a middle bush and 5-10 brackets, wherein the brackets are circumferentially fixed on the outer wall of the middle bush at equal intervals, the middle bush and the brackets are casted into the integrate by using an integrated casting process, and honeycomb fan-shaped material disks are arranged between the adjacent two brackets. The vertical pit furnace bracket type tray of the present invention has advantages of simple structure, low weight, low failure rate, low heat absorption rate, easy casting, and high efficiency.

Description

technical field [0001] The invention relates to the field of well-type furnace spreader equipment components, in particular to a bracket-type tray of a well-type furnace spreader. Background technique [0002] Pit furnace is a cycle furnace, suitable for heat treatment of rods and long shaft parts. The structure of the well-type furnace is: the furnace body is a cylindrical deep well, and the workpiece is vertically loaded into the furnace by a special spreader for heating. The pit-type furnace with a vertical hearth and used for heat treatment of long rod-shaped workpieces is generally circular in cross-section, with a diameter of 0.5 to 4.5 meters. The maximum depth of the furnace can reach more than 30 meters, and the furnace capacity is generally 10 to 20 tons. Long rod-shaped workpieces, such as gun barrels, steam turbine spindles, generator rotors, ship spindles and other rod-type heavy workpieces, are heated vertically in the pit furnace to avoid bending deformation....
