Detailed Parameters Of The Product
Product Description:

    This customized high temperature atmosphere furnace is mainly used in college laboratories, industrial and mining enterprise laboratories, for chemical analysis, physical determination, sintering and dissolution of metals, ceramics, etc., used in electronic components, powder metallurgy, magnetic materials, quartz materials, etc Debinding, pre-sintering and firing can also be used for heat treatment processes of other materials. The furnace body adopts a double-layer furnace shell structure, high-performance heat insulation material, and is equipped with a cooling fan, which makes the surface temperature of the furnace body lower and saves 60% energy compared with ordinary furnaces. The furnace door and furnace roof are sealed with high-temperature silicone rubber, which can be pre-evacuated and can be introduced into a variety of inert gases.

The standard configuration

1 crucible tongs, 1 pair of high temperature gloves, 1 manual, 1 certificate of warranty card


Please pay special attention: H2 is a particularly flammable and explosive gas. Its combustion temperature is 400℃. It will explode when the mixing ratio with air reaches 4.0%-74.2%, so safety measures must be taken when using hydrogen.

The maximum pressure that can withstand in the furnace is 0.03MPa, so a pressure reducing valve must be installed on the gas cylinder when gas is introduced into the furnace.

Before introducing hydrogen, inert gas must be used to clean the furnace. The pressure inside the furnace should always be kept between 0.01-0.02 Mpa during use to prevent air from flowing back into the furnace and causing an explosion.

The room where the equipment is placed must be well ventilated.

The discharged hydrogen must be combusted indoors (the top of the furnace body is equipped with an automatic ignition device) In order to keep the pressure in the furnace chamber relatively stable during the heating process, we recommend that the equipment increase

Temperature rate is less than 10℃/min
