Tswvyim thiab Txhais
Daim txhuam cev titanium faib yog hais txog kev faib tshuaj muaj pes tsawg leeg, cov qauv partic, thiab loj me me muaj pes tsawg leeg hauv cov khoom lag luam tag nrho cov khoom lag luam. Qhov kev xa tawm no ncaj qha rau cov khoom muaj txiaj ntsig zoo ntawm daim txhuam cev titanium thiab muaj kev txiav txim siab txiav txim siab rau tom ntej ua thiab kawg titanium cov khoom siv. Cov lus faib tawm zoo tshaj plaws ntawm daim txhuam cev titanium yuav tsum muaj cov yam ntxwv xws li cov qauv tshuaj sib xyaw ua ke, tsim nyog tus qauv potor, thiab mloog cov particle loj.
Cov ncauj lus kom ntxaws piav txog ntawm cov yam ntxwv faib
1. Tshuaj lom neeg ua haujlwm
Cov tshuaj lom neeg cov tshuaj faib ntawm daim txhuam cev titanium yog feem ntau tau cuam tshuam hauv kev sib txawv ntawm lub ntsiab lus tseem ceeb titanium cov ntsiab lus thiab cov khoom xa tuaj ntawm lub nkoj uas cuam tshuam. Titanium cov ntsiab lus ntawm siab - Zoo spongium yuav tsum ruaj khov ntawm 99.5% thiab 99.8%, thiab yuav tsum nyob ruaj khov ntawm cov pob. Kev faib tawm ntawm cov impurity tseem ceeb xws li cov pa oxygen, thiab lwm yam hauv qab no 0.05%, cov ntsiab lus hlau hauv qab 0.12%. Qhov kev sib txuam ntawm kev faib tawm ntawm cov ntsiab lus ncaj qha cuam tshuam rau kev ua tiav tom ntej.
2. Kev faib khoom ntawm tus qauv pore
Lub Pore cov qauv faib ntawm daim txhuam cev titanium suav nrog cov ntsuas pom xws li porosity, pore loj faib, thiab phat sib txuas. Qhov porosity ntawm high- Cov kab ke zoo tshaj plaws titanium feem ntau yog khaws cia li ntawm 30%, nrog cov hluav taws xob feem ntau yuav tsum nyob hauv thaj tsam ntawm 10-100 microns. Qhov kev xa tawm tsim nyog ntawm tus qauv PEt tau txais txiaj ntsig zoo rau kev tawm ntawm cov tshuaj tsw qab ntawm cov tshuaj tsw qab thaum lub sijhawm melting, kom ua tau zoo ntawm lub ingot.
3. Paus Loj Tshaj Tawm
The particle size distribution of sponge titanium refers to the proportion of particles of different sizes in the overall material. According to different production processes and applications, the particle size distribution of sponge titanium can be divided into multiple grades: coarse particles (>12 hli) tus account rau kwv yees li 15%, nruab nrab, nruab nrab (5-12mm) tus account rau txog 40% -50%, thiab cov khoom zoo (<5mm) account for about 25% -35%. The rationality of this particle size distribution directly affects the loading density and melting efficiency.
