two branch

Silicon carbon components and use temperature is high, hard and brittle, used after molding, such as silicon carbide made of silicon carbide rod, silicon carbon tube heating temperature can reach one thousand and five hundred The operating temperature is 1000-1200 ℃ in vacuum and 1350 ℃ in nitrogen atmosphere

Silicon molybdenum rod

two branch

When heated to high temperature in oxidizing atmosphere, a dense quartz glass film is formed on the surface of the rod to protect it from oxidation. Therefore, Si Mo rod has high temperature oxidation resistance. In the oxidation atmosphere, the temperature can reach one thousand and eight hundred It can be used as heating element of high temperature furnace for electronics, ceramics, magnetic materials, glass, metallurgy, refractory, etc.

Crucible tongs

one hold

1. A common chemical instrument. It is usually used to clamp the crucible. It is generally made of stainless steel, or nonflammable and refractory hard materials.

2. Clean crucible tongs are required.

3. When taking out the hot crucible with crucible tongs, it is necessary to preheat the tongs first, so as to prevent the crucible from cracking due to local cooling. After use, the tongs should be placed upward on the table top or asbestos net.

4. After the experiment, the crucible tongs should be wiped clean, put into the experimental equipment cabinet, and placed dry.

5. The bending part is used for holding the crucible, and the tip is used for other purposes.

6. The crucible tongs may not be used together with the crucible, but can also be used alone.

Quality assurance

The whole machine is guaranteed for one year, except for related consumables (except base plate and heating element) Lifetime door to door maintenance  

Factory environment

1. Indoor use;

2. The range of ambient temperature is 45-5 ℃;

3. The relative temperature of the surrounding environment should not exceed 85%;

4. There is no conductive dust, explosive gas and corrosive gas that can seriously damage metal and insulation around the furnace.

safeguard

1. When the electric furnace is used for the first time or used again after long-term shutdown, it is necessary to dry the furnace, otherwise it is easy to cause furnace cracking.

2. Always keep clean and regularly check the furnace wiring for good contact.

3. When the electric furnace is used, the furnace temperature shall not exceed the rated temperature to avoid damaging the heating elements. It is forbidden to pour various flammable liquids and molten metals into the furnace.

4. In the working process, generally below 300 ℃, the heating rate should not be too fast, because the furnace is cold at the beginning of heating and needs to absorb a lot of heat.

after-sale service

1. We promise to deal with the customer's technical questions within 1 hour.

2. For the equipment returned to the factory for repair, we promise to issue the test results within 1 working day and complete the repair within 3 working days. Special materials need to be customized and handled as appropriate.

3. Return visit the user within 1 week after the equipment is returned to the customer, and provide free consultation on relevant technology.

Friendly tips

1. For the normal service life of the equipment, please do not operate at the set temperature for a long time.

2. Check and check the quantity of goods and accessories carefully when receiving the goods, so as to avoid the inconvenience caused by missing delivery.

3. In order to prolong the service life of the instrument, we suggest that the heating rate and cooling rate should not exceed 10 ℃ / min.

4. The cooling rate should not exceed 5 ℃ / min.

5. The furnace has no vacuum sealing structure, so flammable and explosive gas can not be introduced.

6. After the furnace is used for a period of time, tiny cracks will appear in the furnace, which is a normal phenomenon and will not affect the use. At the same time, it can be repaired with alumina coating.
