Radial sampling device for thermal simulating furnace

Abstract

The invention relates to a radial sampling device for a thermal simulating furnace, which is characterized by comprising a top plate (1), a fire-resistant fiber (2), a plurality of steel pipes (3) and a bottom plate (4); the top plate (1) is fixedly connected with the bottom plate (4) through the steel pipes (3); the fire-resistant fiber (2) is arranged between the top plate (1) and the bottom plate (4); the top plate (1) is provided with an easily-disassembled / assembled gland (5); the top plate (1) is provided with a cross groove (11) and a through hole (12) positioned in the center of the cross groove; and the cross groove (11) and the through hole (12) penetrate through the top plate (1), the fire-resistant fiber (2) and the bottom surface of the bottom plate (4) from the top to the bottom. The radial sampling device has the following characteristics that: 1, a plurality of test samples can be placed; 2, the test samples are arranged in a radial shape, and the true state of a workpiece can be reflected; and 3, the sampling can be carried out at any time; and furthermore, the characteristics of a temperature field in the furnace are not influenced in a sampling process.

Description

technical field [0001] The invention relates to a sampling device, in particular to a radiation type sampling device for a thermal simulation furnace, and belongs to the technical field of heat treatment of metal materials. 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 a process based on experience alone, that is, a conventional heat treatment furnace is used for sampling treatment. Because in the prior art, the sampling structure of the conventional heat treatment furnace is now formed by a circular tube extending into the hearth, and the circular tube is provided with a valve to separate the air duct. Iron wire bundled workpiece samples were taken out for analysis at different time periods. It has the following disadvantages: 1. The number of samples that can be placed is small; 2. The layout of the samples is limited and can only be on the same...
