Comparative analysis of the advantages and disadvantages of graphite heating and silicon molybdenum rod heating under the condition of long-term working temperature of 1750 degree vacuum The heating temperature is generally higher than the working temperature of 200 DEG C according to the calculation, such as the title, heating the working temperature of 1950 degrees Celsius The maximum working temperature of MoSi2 heating material is 1700 DEG c, Graphite heater (rod, tube, plate) in the absence of air in the working temperature of up to 2500 degrees C. Temperature is not the most important factor, the actual long-term working temperature is about 1600 degrees Contact with oxygen in the air, graphite heater easy oxidation, The workpiece will be placed in…
Graphite can be divided into natural graphite and artificial graphite, the two structures are similar, similar physical and chemical properties, but there is a big difference in use. In many studies, some researchers did not notice the difference between the two and generally referred to as graphite. The result of the confusion between the two has caused a lot of misleading, even the wrong decision-making, resulting in a great waste of resources and economic losses. In this paper, from the perspective of the structure and properties of natural graphite and artificial graphite, the characteristics and differences between them are discussed. 1 Graphite classification and characteristics: 1.1 natural graphite Natural graphite is carbon rich organic matter in the geological environment of…
The utility model relates to a graphite electrolytic cell, which relates to an electrolytic cell used for smelting rare earth metals. The main is to solve the problems of rare earth metal graphite electrolytic bath existing contact air directly on the inside of the upper part of rare earth metal smelting, under the condition of high temperature oxidation burning problem of. The invention is mainly in the rare earth metal graphite electrolytic bath with high temperature resistant upper inside protection metal cover, protective cover on the outward along the graphite cell volume will cover the upper, high metal protective cover is approximately equal to the depth of 1/3 graphite cell. The advantages of upper inside of the graphite electrolytic tank…
