Features
1. Operation Temperature: 1700°C/1600°C.
2. Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation.
3. Heavy duty double layer structure with cooling fan. Lower teperature in outside case.
4. PID automatic control via current limiting phase angle fired the resistor, e.g. SCR(Silicon Controlled Rectifier).
5. Power control with 30 segments programmable.
Advantage
High pressure high flow rate gas quenching vacuum furnace that is in the furnace chamber of the specific space using vacuum system (by the vacuum pump, vacuum measurement device, vacuum valve and other components after careful assembly) will be part of the furnace chamber material discharge, so that the pressure in the furnace chamber is less than a standard atmospheric pressure, the furnace chamber space so as to achieve a vacuum state, this is the vacuum furnace.
High pressure high flow rate gas quenching vacuum furnace vacuum environment for heating equipment. The furnace chamber is sealed in a metal or quartz glass enclosure and connected to a high vacuum pump system by piping. The vacuum level of the furnace chamber can reach 133×(10~10)Pa. The heating system can be heated directly by electric resistance wire (e.g. tungsten wire) or by high frequency induction heating. The highest temperature can reach about 3000℃. It is mainly used for ceramic firing, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing, etc.
Advantages of high pressure and high flow rate gas quenching vacuum furnace
1) Oxidation and decarburization of the workpiece surface during the heating process are completely eliminated, and a clean surface without a metamorphic layer can be obtained. This is more relevant to the improvement of cutting performance of those tools that are only ground on one side during sharpening (such as twist drill grinding so that the decarburized layer on the groove surface is directly exposed to the edge).
2) No pollution to the environment, no need for three waste treatment.
3)The accuracy of furnace temperature measurement and monitoring is significantly improved. The indication value of thermocouple and furnace temperature reaches ± 1.5 ° c. But the temperature difference between different parts of a large number of workpieces in the furnace is large, if the use of thin gas forced circulation, can still be controlled within the ± 5 ° c temperature difference.
