Problems solved by technology

However, in the process of use, it is found that in many cases, the effect of using water cooling to reduce the deformation of the furnace mouth is not obvious. In addition, it also increases the probability of water leakage and accidents, and increases the load on the movable platform, which is not conducive to the normal production and equipment. stability

Abstract

The invention discloses a moving sealing element of a preheating furnace, and relates to the field of a high-temperature sealing technology. The sealing element comprises a thermal baffle, wherein the bottom of the thermal baffle is covered by a plurality of U-shaped slots, and the bottom of the U-shaped slot is connected with a connecting shaft through a support; the U-shaped slots are formed in the length direction of the thermal baffle, and a space is formed between every two adjacent U-shaped slots. According to the sealing element provided by the invention, the deformation of the moving sealing element at a furnace mouth of the preheating surface can be effectively reduced; furthermore, the sealing element is good in sealing effect, and safe and reliable to use.

Description

technical field [0001] The invention relates to the technical field of high-temperature sealing, in particular to a moving sealing member of a preheating furnace. Background technique [0002] The preheating furnace is an electrically heated high-temperature furnace, which is used to provide a high-temperature environment for production. It usually includes an inverted furnace body. The furnace mouth of the furnace body is provided with a seal consisting of a heat shield, a U-shaped groove, etc. , the seal is connected to the movable platform through the connecting shaft, and is driven by the movable platform to move back and forth along the furnace mouth. The furnace body of the preheating furnace has very strict requirements on the uniformity of temperature distribution, so the requirements on the sealing parts are also high, especially because the heat insulation plate closing the furnace mouth is not static and requires continuous back and forth movement. In this way, th...
