low-velocity material 中文意思是什麼
low-velocity material
解釋
低速傳震材料-
Liquid - solid extrusion of composite material is a new kind of metal forming process, which has been developed in recent years with a promising practical application prospect for its simple working procedure, low cost and good workpiece performance. through a lot of experiments, the optimization and chosing method of key process parameters ( pouring temperature, mold warm - up temperature, impregnating pressure, impregnating time ) has been mastered. under the precondition of appropriate chosing these parameters, the effective control of extrusion velocity is the key of mading good workpiece. but the control of extrusion velocity remains a handwork, and it is heavily affected by such uncertainties as a handler ' s knowledge and skill about the process. in order to solve the problem, the automatic control of the extrusion velocity is studied, and a computer control system is also designed under existing condition
通過大量實驗，已掌握了關鍵工藝參數（熔液澆注溫度、擠壓模預熱溫度、浸漬時間、浸漬力）的優化選取方法。在合理選取關鍵工藝參數的前提下，擠壓速度的控制是成形出質量良好製件的關鍵。但是，目前對于擠壓速度的控制仍停留在手動控制階段，利用該工藝制備管、棒材製件的成功與否受操作者對該工藝及其設備的經驗及熟練程度等不確定因素影響很大。 -
