Abstract

The invention discloses a tin bath bottom block hydrogen diffusion degree detecting method. The problems of troublesome operation and high cost of the current hydrogen diffusion degree detecting method are solved. The tin bath bottom block hydrogen diffusion degree detecting method provided by the invention comprises the following steps of (1) containing a tin bath bottom block in a first groove, filling a filling layer between the side wall of the first groove and the tin bath bottom block, and coating a sealing layer on the upper surface of the filling layer; (2) opening an air inlet valve and an air outlet valve, and filling hydrogen into an air inlet pipe; (3) simultaneously closing the air inlet valve and the air outlet valve, or closing the air inlet valve before closing the air outlet valve; (4) reading the highest liquid level height difference delta h of a U-shaped pressure gauge to obtain the hydrogen diffusion degree value of the tin bath bottom block.

Description

technical field [0001] The invention relates to a method for detecting hydrogen diffusivity of tin bath bottom bricks. technical background [0002] At present, the indicator for measuring the foaming tendency of tin bath bottom bricks is hydrogen diffusivity. The hydrogen diffusivity is expressed by the difference between the pressure of the air chamber enclosed by the sample and the atmospheric pressure. The existing detection method of hydrogen diffusivity is cumbersome to operate and high in cost. unaffordable for SMEs. Contents of the invention [0003] The invention provides a method for detecting the hydrogen diffusion degree of tin bath bottom bricks, which solves the problems of troublesome operation and high detection cost of the hydrogen diffusion degree detection. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] The method for detecting the hydrogen diffusivit...
