Metal melting tube sealing furnace is a special equipment for melting various metal samples under vacuum conditions. It is mainly used for the preparation of various metal samples and also for the sealing and welding of metal pipes.

Main features:This equipment has the advantages of small size, stable performance, simple and convenient operation and so on. 

Technical parameters:
1. Arc melting chamber: φ200mm × 300mm. The surface of high-quality stainless steel is selected for electrochemical treatment.
2. Melting sample: weight ≤15g (calibrated with stainless steel) / per melting cavity, total 4 melting working stations.
3. Pipe sealing station: can weld the tantalum tube diameter φ5-φ14mm, length 50-100mm; station rotation automatically, speed can be adjusted 0-45rpm.
4. Vacuum degree: The standard mechanical pump is 6.0E-1Pa. If another molecular pump can reach 5.0E-3Pa (the vacuum gauge is not provided as standard)
5. Arc starting mode: high frequency arc starting.
6. Rated input power: 10.4 KVA
7. Cooling method: circulating water cooling
