It has good comfort and can keep hands warm; it is resistant to cutting, wear and heat (it can resist contact heat at 350 ℃ for 60 seconds, and 100 ℃ for 180 seconds) for long-lasting durability.

 

Heating element

Silicon carbide

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.

Special note

Quality assurance

The whole machine is guaranteed for one year, with the exception of related consumables (except for base plate and heating elements) and lifelong on-site maintenance

Factory environment

one Indoor use;

two The ambient temperature is in the range of ± 5-45 ℃;

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

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

safeguard

one When the electric furnace is used or reused after long-term shutdown, it is necessary to dry the furnace, otherwise it is easy to cause furnace cracking.

two Keep it clean and regularly check whether the furnace wiring is in good contact.

three 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.

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

after-sale service

one We promise to solve the customer's technical questions within 1 hour.

two 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.

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

Friendly tips

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

two Carefully check and check the quantity of goods and accessories when receiving goods, so as to avoid inconvenience caused by less delivery and missing delivery.

three In order to prolong the service life of the instrument, we suggest that the heating rate and cooling rate should be 10 ℃ / min.

four The cooling rate should not exceed 5 ℃ / min

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

six 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.
