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. Adjust the pressure regulator to the relative pressure ≦0.05Mpa. Open the intake valve and observe the absolute pressure gauge at the intake end. Adjust the flow, observe bubbles, and protect the atmosphere normally.

When cracks occur after ≧5mm, the shrinkage of fiber in non-refractory layer is generally caused by the erosion of volatiles of sintered materials (strong acid and alkali, or lead vapor and vanadium pentaoxide). In actual use cases, some components added in zirconia products of sintered materials and volatiles of dyeing agent of customers are easy to cause cracking of fiber products when caking ...

For a long time, the electric heating alloy used at a high temperature above 1400 ° C in China is basically dependent on foreign imports, but its price is quite expensive, which has brought no small pressure to the production and use of high temperature electric heating furnaces in China. The domestic 0Cr27Al7Mo2 not only the use temperature is not ideal, but also the cold processing performance is poor, in order to solve this problem,... Please enter for more information
