Embodiment Construction

[0022] In order to better understand the present invention, the technical scheme of the present invention will be further described below in conjunction with embodiment and accompanying drawing (as figure 1 , 2 shown).

[0023] Multi-layer heat-resistant protective casing, which includes a stainless steel casing; its feature is that: the pipe wall of the stainless steel casing is the first stainless steel layer 1, the corundum ramming material layer 2, and the second stainless steel layer from outside to inside. Layer 3, vacuum layer 4, third stainless steel layer 5, thermal insulation material layer 6 and fourth stainless steel layer 7.

[0024] The first stainless steel layer 1 is: SUS314 stainless steel with metal composite material added with 5% palladium metal (the first stainless steel layer 1 has high hardness, high oxidation resistance, and is used to protect inner layer structures such as the corundum ramming material layer 2); The second stainless steel layer 3 , t...

Abstract

The invention relates to the field of thermal insulation, in particular to a multi-layer thermal insulation protection sleeve and application thereof. The multi-layer thermal insulation protection sleeve comprises a stainless steel sleeve body, and is characterized in that a pipe wall of the stainless steel sleeve body is sequentially composed of a first stainless steel layer, a corundum ramming material layer, a second stainless steel layer, a vacuum layer, a third stainless steel layer, a thermal insulation material layer and a fourth stainless steel layer from outside to inside. Due to thedesign of the multi-layer thermal insulation, it can be ensured that the temperature in the sleeve is the normal working temperature of a cable; the sleeve does not need to be cooled by water or gas,the outer wall of the sleeve is not prone to burning through and is more resistant to high temperature, and safety is improved.

Description

technical field [0001] The invention relates to the field of heat insulation and heat preservation, in particular to a multilayer heat-resistant protective sleeve and its application. Background technique [0002] Traditional industrial enterprises usually install disposable thermocouple temperature measurement control devices for temperature measurement in high-temperature areas (2800°C to 800°C). Because in high-temperature environments, traditional devices use water-cooling or water-air cooling to easily cause leakage damage. , and has not been effectively resolved. For example, the temperature detection of molten steel or molten iron is required in ironmaking, steelmaking, and continuous casting processes in steel mills. At present, it is commonly used to install the thermocouple temperature measuring device with water jacket cooling (the water jacket cooling can ensure that the cable of the thermocouple temperature measuring device can work normally at a normal tempera...
