Analysis of corundum tube cracking at high temperature
High temperature tube furnace, vertical tube furnace, atmosphere CVD system, using corundum furnace tube as heating cavity high purity corundum furnace tube (or corundum products), while making use of its high purity and high temperature quality characteristics, we must follow the inherent characteristics of corundum material (relatively poor thermal shock resistance, not resistant to acute […]
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 […]

Melt-blown cloth nozzle (plate) mold disjunction cleaning installation need to know the knowledge
Melt-blown cloth nozzle (plate) mold unknot cleaning and installation precautions: In order to prevent the oxidation of the abrasive tool and the blockage of the nozzle, the furnace must be cleaned by the melt-blown cloth nozzle (spinneret) which can be vacuum or atmosphere Spinneret cleaning and sintering curve setting: A vacuum sintering: 1. The vacuum […]
Introduction of HRE electric heating wire
For a long time, the electric heating alloy used at a high temperature above 1400 ° C 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. The domestic 0Cr27Al7Mo2 not only the use temperature is […]
