specific Embodiment 1

[0021] refer to figure 1 , figure 2 and image 3 , this embodiment includes a housing 1 and a hollow flange 2 connected to the top of the housing 1; the inner cavity of the hollow flange 2 is divided into an air inlet chamber 2-1 and a heat insulation chamber 2-2; in the air inlet chamber 2- The side wall of 1 is provided with several evenly distributed air intake holes 2-1a, and thermal insulation cotton 3 is provided in the heat insulation cavity 2-2; several uniformly distributed cooling air ducts 4 are provided on the outer wall of the housing 1 , the air inlet 4-1 of the cooling air passage 4 communicates with the air inlet cavity 2-1, and the air outlet 4-2 thereof is open.

[0022] In this example:

[0023] The outer shape of the hollow flange 2 is that the lower part is in the shape of a truncated inverted cone, and the upper part is in the shape of a cylinder. Since the lower part of the hollow flange 2 is in the shape of a truncated inverted cone, it can be conn...

specific Embodiment 2

[0028] The characteristics of this embodiment: the outer shape of the hollow flange 2 is truncated and inverted conical. The number of the air intake holes 2-1a is two, three, four, five, six, seven, nine, ten or twelve. Others are the same as in Example 1.

specific Embodiment 3

[0029] The characteristics of this embodiment: the number of the cooling air ducts 4 is two, three, four, five, six, seven, nine, ten or twelve. Others are the same as in Example 1.

Abstract

The invention relates to a uniform-heating screen with a cooling structure for a thermally-stimulated furnace, which is characterized by comprising a shell (1) and a hollow flange (2), wherein the hollow flange (2) is connected to the top of the shell (1); an inner cavity of the hollow flange (2) is divided into an air-inlet cavity (2-1) and a heat-insulating cavity (2-2); a plurality of uniformly-distributed air-inlet holes (2-1a) are arranged on the lateral wall of the air-inlet cavity (2-1), and heat-preserving cotton (3) is arranged in the heat-insulating cavity (2-2); and a plurality of uniformly-distributed cooling-air channels (4) are arranged on the outer wall of the shell (1), an air inlet (4-1) of each cooling-air channel (4) is communicated with the air-inlet cavity (2-1), and an air outlet (4-2) of each cooling-air channel (4) is open. The uniform-heating screen has the characteristics that a workpiece can be more uniformly heated, and meanwhile, the cooling speed can be accurately controlled.

Description

technical field [0001] The invention relates to a heat soaking screen, in particular to a heat soaking screen with a cooling structure for a thermal simulation furnace. The invention belongs to the technical field of metal material heat treatment. Background technique [0002] At present, the domestic heat treatment of large castings and forgings with a press of more than 8,000 tons is still in the stage of formulating the process based on experience. Often due to improper process, the performance is unqualified or cracking is caused by excessive quenching residual stress. Therefore, domestic heavy machinery factories have to trial-manufacture each large-scale casting and forging. The process cycle is long and the cost of trial-manufacturing materials is high. Now the country has begun to use process simulation furnaces for simulation tests. However, due to defects such as temperature uniformity, accuracy, and process adjustment flexibility of the existing equipment, and th...
