Product description:
The KJ-MZ1100 series vertical lifting bell furnace can lift the heating zone, making it easier to deliver and take materials; the welding quality is good, the strength is high, and the stability is strong. The furnace has the advantages of balanced temperature field, low surface temperature, and energy saving.

Application:
Diamond grinding wheels, saw blades, hard tools, ceramics and alloy materials, high vacuum welding, high temperature sintering, annealing, and heat treatment of metal materials.

features

1. The heating element adopts high-quality resistance wire, and the furnace insulation material adopts polycrystalline fiber material, which has good insulation performance, durability, high tensile strength, no impurities, high purity, and energy-saving
2. The entire furnace body adopts a vertical structure with an air gap in the middle. Even if the furnace temperature is as high as 1000℃, the surface of the furnace body can still be safely touched without a hot feeling.
3. The entire furnace body adopts a vertical structure with an air gap in the middle. Even if the furnace temperature is as high as 1000℃, the surface of the furnace body can still be safely touched without a hot feeling.
4. The temperature control system adopts touch screen control, artificial intelligence adjustment, PID adjustment, self-tuning function, 30 sections of temperature rise and fall programs can be compiled, and data can be stored and output.
5. With over-temperature alarm protection function, the operation is safe and reliable.
6. The tubular furnace has reserved air inlet and outlet ports, and a vacuum pump interface is reserved. The vacuum pump can be connected to vacuum.
