Cara nambah roughness saka wesi castings

2022-11-02

Wangun wedhi banget mengaruhi permukaan. Umume digunakake yaiku pasir bunder, persegi lan segitiga. Pasir segitiga sing paling awon. Longkangan antarane wedhi gedhe nalika wedhi nyampur. Yen resin wedhi casting, iku biaya persil saka resins.

2) Bahan sing dibutuhake saka casting

Sawetara bahan ora cocok kanggo casting wedhi, kayata sawetara bahan karo manganese banget kurang. Komponen sing dicetak saka bahan kasebut kanthi penyusutan sing abot lan permukaane banget kasar.

3) Sistem Pengisian

Yen sistem pouring ora dirancang cukup, bakal shrinkage lan cacat cast ora cukup. Yen sistem slag suppress ora cukup, slags bakal mili menyang rongga casting, kang bakal nimbulaké cacat pori wedhi. Iki bakal mengaruhi roughness.

4) Slagging

Yen slags ing banyu wesi nyawiji ora cukup mbusak utawa ora filtrated cetha sak pouring proses, slags bakal diwutahake menyang growong cast. Iki bakal nyebabake cacat inklusi slag. Iki bakal mengaruhi roughness.

5) Operasi sing ora bener

Operasi sing ora bener uga bisa nyebabake cacat casting lan permukaan kasar. Operasi sing ora bener kasebut kalebu, pasir sing ora cukup diresiki sajrone cetakan cetakan, pasir sing ora dipadhetke sajrone model, lan tingkat sing cocog ing antarane pasir. Yen wedhi utawa model ora cukup kuwat, cacat bolongan wedhi bakal disebabake.

6) Persentase saka P

Yen P

Miturut pengalaman, nambah sawetara resistances suhu dhuwur bisa nambah roughness lumahing casting wedhi precoated. Resistances suhu dhuwur kasebut bisa entuk sintering fase padat, sing nambah kekasaran utawa tingkat pengecoran wesi sing lancar.
