Cause analysis of chamber crack in high temperature furnace
In the field of ultra-high temperature, high-quality high temperature furnace refractory layer is made of alumina polycrystalline fiber products. In high-end and high-quality laboratory equipment, box type furnace and tube type furnace, most of them use this material. Using the “colloidal method” process, the soluble aluminum, silicon salt made of colloidal with a certain viscosity, […]
Precautions for the use of mini tube furnace
1. After the sample is placed, the two heat insulation plugs should be placed in the correct position. Select a small pressure reducer and connect them as shown in the figure below; 2. The pressure reducer is adjusted to the relative pressure ≦0.05Mpa. Open the intake valve and observe the absolute pressure gauge at the […]
