Molybdenum alloy extrusion

Nws yog siv los tsoo coarse li-cam khwb cia nplej thiab txhim kho kev ua tau zoo ntawm ingots. Nws kuj tseem tuaj yeem siv los tsim cov kav dej, tuav thiab profiles. Nyob rau hauv kev txiav txim siab tuav cov as-cam khwb cia nplej, cov extrusion piv yuav tsum tsis txhob yuav tsawg tshaj li 4, thiab cov extrusion kub yog feem ntau nyob nruab nrab ntawm 1100 thiab 1315 ° C. Yog tias cov khoom lag luam thiab cov khoom nruab nrab tau txais ncaj qha los ntawm extrusion, qhov sib piv loj dua thiab siab dua extrusion yuav tsum tau siv. Txhawm rau kom ntev lub neej ntawm cov pwm thiab xyuas kom meej qhov loj thiab qhov zoo ntawm cov khoom, cov pwm yuav tsum tau coated nrog zirconium dioxide los yog aluminium oxide refractory, thiab lubricated nrog lub iav lubricant thaum lub sij hawm extrusion.
