Apa Fungsi Perawatan Panas kanggo casting investasi

2022-11-22

Proses perawatan panas minangka salah sawijining teknologi paling impor kanggo desgin casting investasi. Perawatan panas bisa mbantu nambah sifat bahan casting kanggo entuk syarat properti mekanik tartamtu, kayata kekuatan dhuwur, kekerasan utawa resistensi nyandhang, kanthi ngganti struktur internal bahan kasebut.


Perawatan panas ngemot sawetara proses kanggo nyukupi sifat mekanik sing dibutuhake:


1) Siji proses panas-nambani castings investasi tanpa ngganti struktur utama saka castings. Biasane digunakake kanggo ngilangi stres internal, sing bisa uga disebabake ora cukup wektu kanggo pendinginan utawa masalah kahanan udara liyane.


2) Proses perawatan panas liyane bakal ngganti struktur njero bahan. Teknik utama kaya ing ngisor iki,

a. Pengobatan tempering

Fungsi utama kanggo proses perawatan panas iki yaiku kanggo ngurai karbida, saéngga nyuda kekerasan casting. Iki bisa bantuan kanggo mesin castings gampang. Kanggo casting wesi ductile, perawatan tempering bisa bantuan kanggo njaluk struktur ferritic liyane kanggo nambah kualitas casting.

b. Pengobatan annealing

Fungsi utama kanggo proses perawatan panas iki kanggo njaluk struktur pearlite lan sorbite saka casting, mangkono kanggo nambah sifat mechanical saka casting investasi.

c. Pengobatan hardening

Fungsi utama perawatan hardening yaiku kanggo entuk kekerasan sing luwih dhuwur, saéngga nambah properti resistensi nyandhang.

d.perawatan pengerasan lumahing

Fungsi utama perawatan permukaan-hardening kanggo njaluk lapisan hardened ing lumahing casting, mangkono kanggo nambah resistance nyandhang saka castings. Dibandhingake karo perawatan hardening, perawatan hardening lumahing biasane digunakake kanggo sawetara wilayah khusus saka casting. Pengerasan induksi akeh digunakake kanggo proses perawatan permukaan iki.

e. Perawatan hardening udan

Perawatan hardening udan digunakake kanggo nambah kekuatan casting, tanpa ngganti properti elongation saka casting.
