Molybdenum Electrode For Optical Glass Diameter 50*1000mm
1. Description of Molybdenum Electrode For Optical Glass Diameter 50*1000mm:
The continuous melting furnace used for the production of optical glass is a furnace supplemented by electric heating and gas heating. As an important part of continuous melting furnace, the quality of molybdenum electrode is the key to the production of optical glass with excellent performance. In the preparation process, the sintered molybdenum ingot was subjected to ten-die forging twice, and the total deformation amount reached 83%. Therefore, the obtained molybdenum electrode has higher density and larger size. In addition, the impurity content of the molybdenum electrode is also a key factor affecting the quality of the glass. Therefore, in the process of preparing the molybdenum electrode, the composition of the raw material molybdenum powder should be strictly controlled. At the same time, the sintering process of molybdenum ingots is improved, and the content of C and O is reduced. In addition, it is very important to strictly control the cleanliness and sanitation of the preparation workshop, strictly operate according to the process requirements, and prevent the contamination of molybdenum ingots by impurity elements. Adoption can also reduce the impurity content in the electrode.

4. Product requirement of Molybdenum Electrode For Optical Glass:
One is the surface of forged molybdenum electrode rod, which is not allowed to have oxide film and slight forging hammer mark. The other is that the surface of the polished molybdenum electrode rod has a metallic luster without obvious oxidation. The common advantage of both types offered by this company is that there are no defects in them - no delamination, no cracks, no burrs, no vertical cracks, etc. We will do non-destructive testing to check whether there are cracks inside each step, and finally present to customers high-quality molybdenum electrode products.
