Abstract

The invention provides a high-temperature protection device for a hydrogen measuring instrument, which is a flip type box body, and when the hydrogen measuring instrument is used for measuring the hydrogen content of molten aluminum, an operator puts the hydrogen measuring instrument into the high-temperature protection device for the hydrogen measuring instrument; in order not to influence the normal use of the hydrogen measuring probe, a probe hole is reserved at the turnover cover of the box body and is used by the hydrogen measuring probe; in order to clearly see parameters and display of the hydrogen measuring instrument, the flip cover of the high-temperature protection device of the hydrogen measuring instrument needs to be made of a transparent material; the high-temperature protection device for the hydrogen measuring instrument is used beside high-temperature molten aluminum, and the used material is required to have good corrosion resistance and heat resistance, so that 304 stainless steel is selected as the shell material of the high-temperature protection device for the hydrogen measuring instrument; in order to better isolate the high temperature transmitted by the molten aluminum, a layer of heat insulation cotton needs to be laid on the side, close to the molten aluminum, of the high-temperature protection device of the hydrogen meter; in order to prevent heat from gathering in the high-temperature protection device of the hydrogen measuring instrument, a compressed air inlet and an air outlet are formed in the two sides of the high-temperature protection device of the hydrogen measuring instrument respectively, compressed air is communicated for purging and cooling during hydrogen measurement, and the whole device has a very targeted protection effect.

Description

technical field [0001] The invention relates to the field of chemical operation auxiliary equipment, and more specifically, to a high temperature protection device for a hydrogen measuring instrument. Background technique [0002] In aluminum and aluminum alloy melts, hydrogen has a simple atomic structure and a small radius, and it dissolves significantly under normal smelting conditions. The gas existing in molten aluminum is mainly hydrogen, accounting for about 70% to 90% of the entire gas content. Liquid aluminum A large amount of hydrogen gas is precipitated during solidification, which makes aluminum castings prone to defects such as pinholes and pores. Therefore, dehydrogenation of molten aluminum is one of the essential processes. In order to detect the hydrogen content in molten aluminum, a special hydrogen detector is needed, but the price of the hydrogen detector is high, and the hydrogen detector needs to be placed on the aluminum liquid chute for a long time wh...
