High temperature vacuum furnace

The furnace of high temperature vacuum electric furnace is made of high-purity alumina polycrystalline fiber material with good heat preservation performance. The heating element is high temperature alloy heating wire. Double shell structure and pid30 program temperature control system, phase-shifting trigger, silicon controlled control, furnace using soft and hard carbon fiber materials, can quickly rise and fall temperature. The furnace door is equipped with a circulating water cooling system, which can quickly cool the side open furnace door structure of the furnace body. Meet the different needs of production and R & D.

The high temperature vacuum furnace is equipped with a flange joint of DN150mm to connect the diffusion pump on the side, and a vacuum pump after the diffusion pump. It is equipped with a vacuum valve, a composite vacuum gauge, etc. the furnace has the advantages of small volume, balanced temperature field, low surface temperature, fast temperature rise and fall rate, favorable price, energy saving, etc. it is an ideal product for vacuum sintering in universities, scientific research institutes, industrial and mining enterprises.

Application of high temperature vacuum furnace:
High temperature vacuum furnace is mainly used for heat treatment of electronic components, new materials and powder materials in vacuum or atmosphere. Also used in metallurgy, machinery, light industry, commodity inspection, institutions of higher learning and scientific research departments, industrial and mining enterprises electronic ceramic products pre firing, sintering, brazing and other processes. It can realize no oxidation, no decarburization, no carburization, can remove the phosphorus chips on the surface of the workpiece, and has the function of degreasing and degassing, so as to achieve the effect of surface bright purification.

Classification of high temperature vacuum furnaces:
According to the electrode type, the high temperature vacuum furnace can be divided into two categories: consumable furnace and non consumable furnace. The main industrial use is the self consumption furnace. There are also furnaces with consumable electrode and non consumable electrode at the same time. The main charge is provided by consumable electrode, and the auxiliary heating is conducted by non consumable electrode. Such furnaces are often used for casting furnaces.

The electrode of the consumable furnace is made of the melted material itself, which is called consumable electrode. In the smelting process, the electrode end is gradually melted and dropped into the water-cooled copper crucible, and the electrode itself continuously consumes itself. High temperature vacuum furnace is mainly used for remelting the billets of active metals and refractory metals such as titanium, zirconium, molybdenum, tantalum and niobium to make ingots, such as remelting the sponge titanium electrode into titanium ingots. The high temperature vacuum furnace can also be used for refining alloy steel and making large-diameter high-quality ingots, such as forging billets for generator shafts and rolls.

The electrode of non consumable furnace is made of high melting point materials such as tungsten. The electrode itself is not consumed in the work, and the furnace charge needs to be added into the furnace by other ways. This kind of high temperature vacuum furnace is mainly used for casting the special-shaped castings of the above materials in vacuum and making the test ingots in the laboratory.

Features of high temperature vacuum furnace:
1. High melting temperature, up to 3500 ℃
2. All stainless steel design vacuum cavity small, good sealing, can quickly vacuum, fast filling argon, fast efficiency and argon consumption is very small.
3. The water-cooled copper electrode can move 360 degrees, and the operation is flexible. At the same time, the water-cooled crucible is small and replaceable, which can be customized.
4. With turning device, customer service material single side melting uneven situation.
5. It can be equipped with high vacuum system, and the furnace body is equipped with quick connection interface, which is convenient for disassembly.
6. Adopt over temperature protection and add filter glass to protect eyes.
7. Desktop design, delicate and light, flexible movement.
