Ntau lawm txoj cai thiab kev daws teeb meem ntawm daim tawv nqaij wrinkled
Cov tawv nqaij wrinkled ntawm castings yog tsuas yog tshwm sim raws li qhov tshwm sim tsis sib xws zoo ib yam li cov tawv nqaij wrinkles ntawm qhov chaw ntawm castings, uas cuam tshuam rau qhov zoo ntawm qhov zoo thiab cov khoom siv ntawm castings. Qhov tshwm sim ntawm qhov tsis xws luag no feem ntau yog ze rau cov hlau ntws hauv lub xeev thaum lub sij hawm txias ntawm cov casting, pwm pwm thiab txheej txheem pouring.
Wrinkled daim tawv nqaij tsis xws luag tiam txoj cai
Cov kua hlau tsis zoo:Lub casting kua hlau nyob rau hauv cov txheej txheem pouring yog tsis txaus liquidity, uas ua rau lub filling ntawm lub pwm kab noj hniav yuav tsis tau tag nrho cov tsim, tshwj xeeb tshaj yog nyob rau hauv lub puab ces kaum los yog complex qauv, cov dej ntws ntawm cov kua hlau yog thaiv, nto shrinkage thaum txias, sib sau. daim tawv nqaij wrinkled.
Cov pwm kub tsis sib xws:Qhov kub ntawm txhua feem ntawm cov pwm tsis zoo ib yam, tshwj xeeb tshaj yog nyob rau hauv cheeb tsam uas pwm kub tsis dhau tom qab pouring, cov hlau ua kua txias ceev yog ceev heev, qhov saum npoo yog sai solidified, thiab cov kua hauv cov hlau tsis tuaj yeem ntxiv cov nto shrinkage, tsim wrinkled daim tawv nqaij.
Tsis zoo casting ceev thiab kub:qhov ceev nrooj nrawm dhau los yog qhov kub ntawm qhov casting siab dhau lawm, thiab cov kua hlau ua rau muaj kev cuam tshuam thiab turbulence nyob rau hauv cov pwm kab noj hniav, uas ua rau tsim cov oxide ntawm daim tawv nqaij los yog inclusions nyob rau saum npoo ntawm cov kua hlau, thiab tsim wrinkled. daim tawv nqaij tom qab txias.
Pwm tso pa tsis zoo:pwm tso tawm tsis du, ua rau cov roj hauv cov kab noj hniav tsis tuaj yeem tawm hauv lub sijhawm, cov hlau ua kua dej yog thaiv hauv qab cov roj thaiv, thiab qhov chaw yog wrinkled tom qab txias.
Wrinkle daim tawv nqaij tsis haum tshuaj
Txhim kho cov kua hlau ntws:Ua kom zoo ntawm cov hlau sib xyaw, tswj cov viscosity thiab ntws ntawm cov kua hlau, thiab xyuas kom meej tias cov kua hlau tuaj yeem ua tiav hauv cov pwm kab noj hniav thaum lub sij hawm nchuav txheej txheem kom tsis txhob muaj kev cuam tshuam.
Kho cov pwm kub:Los ntawm preheating cov pwm, ua kom cov pwm kub tsis sib xws, ua kom cov hlau ua kua txias ceev, kom tsis txhob muaj cov tawv nqaij sai sai, txo qhov tsim ntawm daim tawv nqaij wrinkled.
Optimization ntawm cov txheej txheem pouring:tsim nyog tswj ntawm pouring ceev thiab pouring kub, tsis txhob muaj zog tej yam kev mob thiab turbulence ntawm hlau kua nyob rau hauv lub pwm kab noj hniav, txo qhov tsim ntawm oxide thiab inclusions.
Txhim kho cov pwm tso tawm:Txhim kho cov pwm tsim, xyuas kom meej tias cov pwm tso tawm channel yog du, raws sij hawm tso cov pa tawm hauv cov kab noj hniav, thiab zam cov roj uas cuam tshuam cov kua hlau ntws.
Kev siv cov xim zoo nkauj:kev siv zoo permeability, muaj zog adhesion txheej, uniform txheej pwm nto, txo qhov kev sib cuag ncaj qha ntawm hlau kua thiab pwm, txo qhov kev pheej hmoo ntawm wrinkle.
