Proper use of high temperature furnace

For high temperature furnace how to use must be known to everyone, no one is not clear, in fact, because too familiar with high temperature furnace how to use just can appear some wrong use method oneself do not know, today small make up to tell you about the correct use method of high temperature furnace. First, we need to know the high temperature furnace is a general-purpose heating device, also known as the high temperature muffle furnace, is commonly used high temperature furnace muffle furnace, average temperature can reach 900-1100 ℃ (because of different heat source), commonly used in metal melting, ashing and weight analysis of organic compounds, etc. High temperature furnace has form a complete set of automatic temperature control, is used to set, control, measurement of temperature in the furnace;

Proper use of high temperature furnace:

(1) high temperature furnace to placed in the cement of the solid mesa, don't hold around chemical reagent, more do not have a flammable and explosive goods high temperature furnace to make special control power supply switch * new furnace heating, temperature to repeatedly is presented.the adjustment, slow rise, melting or burning in the oven sample, must be strictly controlled and zui high furnace temperature, temperature in order to avoid sample splash, corrosion and bonding furnace. Such as burning organic matter, such as filter paper, must advance ashing, furnace lining on clean, flat sheet of refractory material and so as not to spill accident happened no time damage the furnace wall,

(2) Power should be cut off first after use, and the furnace door can only be opened after the temperature falls below 200℃. The power must be cut off when loading the sample to avoid electric shock. The opening time of the furnace door should be as short as possible when loading the sample to extend the service life of the electric furnace. Do not use the clip stained with water and oil to take the sample, wear gloves when taking the sample, in order to burn, the sample should be placed in the middle of the furnace, neatly placed, do not randomly touch the electric furnace and the surrounding samples should be cut off after the use of water, do not exceed the maximum temperature of the resistance furnace.
