Molybdenum Wire Rolling Narrowband Deformation Analysis And Calculation Method Of Silk Diameter

This article discusses the narrow circular molybdenum wire molybdenum in the process of rolling deformation are analyzed by theoretical calculation derived molybdenum wire molybdenum rolling band formula, and formulas for analysis. The method has great intuition, through the formula to predict the required wire diameter. Molybdenum wire rolling process with development of the influencing factors on the width obtained excellent performance, meet the technological requirements of high-precision Mo narrowband.The results of the study indicate that:1. With molybdenum wire rolling narrowband, silk diameter choice is very important.2. Narrowband rolling to hot-rolled advisable, temperature 800 -900℃, and select 20-30% processing, obligate drawing manufactured 5-10 percent. Narrowband lane width can be through before and after processing, the parameters such as tension, temperature adjustment, to achieve the ideal change state of curing process, conducted batch production.3. Cold drawn shaped mold orthotics, can substantially improve the dimensional accuracy to meet the tolerances, Electrochemical polishing can remove defects such as surface oxidation, burr, improve surface finish, so as to meet the index requirements.4. Through the control rolling passes, pass times of reduction, tension and friction coefficient etc, can precisely control rolling parameters in the process of flattening molybdenum wire Spread quantity. 5. Formula (?)accurate estimate required silk diameter, rolling narrowband may also use the formula about certain estimate diameter raw silk finished product specifications.
