Technical Features

1.Good reproducibility of melt sample effect

The machine employs a design that simultaneously features both front and rear swing of the furnace body and self-rotation of the sample holder, ensuring a whirling motion of the molten sample, which achieves excellent uniformity and bubble removal effects.

2.Melting samples at various temperatures suitable for different materials:

Due to the use of silicon carbide rod heating, platinum-rhodium thermocouple temperature measurement, PLC control, a simple operating system, and default design of common parameters, it features simple operation, safe usage, high degree of automation, and high temperature control accuracy. It can achieve high-quality melting of various materials at different temperatures, meeting the requirements of various industry analysis standards.

3.Multiple protection features equipped

Equipped with multiple protection features such as disengagement and over-temperature, the device employs both hardware and software dual protection when exceeding temperature limits or travel limits, ensuring long-term stable operation.

4.Design features an independent exhaust duct.

An independent exhaust duct that expels corrosive gases generated during the melting process promptly, reducing corrosion to the furnace refractory materials and crucible supports, and extending the lifespan of internal equipment components.

5. Crucible Air Cooling Unit

One-touch crucible air-cooling machine, significantly reduces sample cooling time, and markedly improves melting efficiency.

6. Enhanced pre-oxidation feature for easier melt sample preparation

Brand new designPre-oxidation feature eliminates the cumbersome original pre-oxidation process in a muffle furnace, reducing operational steps, and simplifying the melting sample process.

7. Heating element enhances equipment's heating efficiency significantly

The equipment utilizes a new heating element, significantly reducing the heating time from room temperature to...It takes about 25 minutes at 1100 degrees. After opening the furnace cover to remove the crucible and then replacing it, the equipment's reheating efficiency increases by about 70%. The new heating element has a longer overall lifespan, with an average usable duration of 8-12 months based on the frequency of use.

8. New furnace chamber design extends furnace lifespan

Novel furnace chamber materials have brought about significant innovation in refractory selection, with the use of zirconia-alumina raising the long-term operating temperature of the furnace chamber to1350°. The new furnace chamber structurally resolves the long-standing issue of poor thermal shock resistance and cracking in the old-style furnace chamber. It fundamentally addresses the problem of cracking caused by thermal shock under rapid cooling and heating conditions. The lifespan of the new furnace chamber is on average extended by 8 to 12 months compared to the old-style furnace chamber.
