    High-temperature furnace atmosphere is an advanced laboratory equipment, applicable to all major universities, research institutes, industrial and mining enterprises, materials and other materials in different industries.      
High temperature atmosphere furnace for metal, nano, monocrystalline silicon, polycrystalline silicon under, batteries, etc. as well as vacuum gas diffusion welding, heat treatment atmosphere heating equipment.
Mainly used for materials testing, synthesis and sintering. Good furnace insulation performance, energy-saving effect is remarkable. Can also be used, composite materials, powder materials, structural ceramics, alloy vacuum sintering experiments.       
Standard high-temperature atmosphere furnace temperature: 1100 ¡æ, 1400 ¡æ, 1600 ¡æ, 1700 ¡æ and so on.       
High temperature atmosphere furnace standard sizes: 200 * 150 * 150, 300 * 200 * 250 * 250,400 * 200,300 * 300 * 300 and so on.
Wash furnace steps:
1, with the protective gas expelled from the furnace Air Act:
(1) generally should pass into the protective gas furnace before the heating furnace;
(2) shielding gas through the upper and lower, after three pass into the mouth wash, the exhaust port of the needle valve should be open to the maximum, the air is discharged as soon as possible in order to facilitate the furnace;
(3) generally into the furnace through the furnace volume of about 10 times the shielding gas, the oxygen concentration in the furnace can be reduced to about 10ppm;
(4) When the oxygen concentration in the furnace process in line with the requirements of the product, you can vent off a small needle to save protective gas, wash mouth shut from entering the air intake through the meter;
(5) The use of the process in an electric furnace, the furnace must maintain a positive pressure to prevent outside air from entering the furnace hearth.
2, with the pre-vacuum pump method:
(1) to any one of the outlet nozzle and the vacuum hose connected;  
(2) pre-vacuum furnace chamber;
(3) pass into the protective gas;  
(4) and then the pre-vacuum oven cavity.   
 Protech products mainly include Laboratory Muffle furnace,Tube furnace,Dental furnace like lab muffle furnace, dental lab furnace, dental porcelain furnaces, dental zirconia sintering furnaces, gold melting furnace, SiC heating element, MoSi2 heating element, alumina tubes and crucibles, and etc.
