Igwe ọkụ na-eguzogide ụdị igbe usoro ntọala paramita

1. Mkpebi nke ọkụ ọkụ

Mgbe a na-eji ọkụ ọkụ ngwa ngwa na igbe igbe, a na-atụle ndụ ọrụ nke waya nguzogide. N’ozuzu, ọkụ okpomọkụ ka atọrọ na 920 ~ 940 ℃ (na-eguzogide waya mere nke chromium-nickel ihe onwunwe), 940 ~ 960 ℃ (resistance waya mere nke ígwè-chromium-aluminom ihe) ma ọ bụ 960 ～980 ℃ (The iguzogide waya bụ ihe nwere ihe ndị dị ka niobium na molybdenum).

2. Ịchọpụta ọnụọgụ ọkụ arụnyere

A na-ekpebi oke ọkụ etinyere dịka ike ọkụ na mpaghara eji. Ụkpụrụ bụ: elu nke mgbidi ọkụ nke mbụ ogbe nke workpieces eruwo kpọmkwem okpomọkụ tupu arụnyere ọkụ, na ọkụ okpomọkụ nwere ike ngwa ngwa laghachi kpọmkwem okpomọkụ mgbe ọ bụla echichi. Ọ bụrụ na ibu ọkụ ọkụ dị oke ibu ma ghara ikwekọ ike ọkụ ọkụ ahụ, a gaghị eweghachi ọkụ ọkụ ọkụ ruo ogologo oge, nke ga-emetụta nzizi nke ngụkọta oge. Na mmepụta oke, enwere ike “belata ya n’ime akụkụ” ma na-aga n’ihu na batches.

3. Mkpebi nke oge kpo oku

A na-agbakọ oge kpo oku ngwa ngwa dabere na nha dị irè nke ngalaba obe workpiece, wee kpebisie ike dabere n’ọnọdụ dị adị na ahụmịhe gara aga:

(1) Enwere ike ịgbakọ oge ikpo ọkụ ngwa ngwa nke otu ibe dị ka ndị a:

t=ad

Ebe t: oge ​​kpo oku ngwa ngwa (s);

a: Ngwakọta oge kpo oku ngwa ngwa (s / mm);

d: The irè dayameta ma ọ bụ ọkpụrụkpụ nke workpiece (mm).

N’ime ọkụ ọkụ na-eguzogide ụdị igbe, dayameta dị irè ma ọ bụ ọkpụrụkpụ nke workpiece bụ ihe na-erughị 100mm, na ngwa ngwa kpo oku oge ọnụọgụ a bụ 25-30s / mm;

The irè dayameta ma ọ bụ ọkpụrụkpụ nke workpiece karịrị 100mm, na ngwa ngwa kpo oku oge ọnụọgụ a bụ 20-25s / mm.

Gbakọọ oge kpo oku ngwa ngwa dị ka usoro a dị n’elu, nke a ga-edozi n’ụzọ kwesịrị ekwesị dị ka ọkụ ọkụ kpebisiri ike ma kpebisie ike mgbe ị gafechara nkwenye usoro.

(2) Mgbe a na-emepụta akụkụ na batches, na mgbakwunye na ngụkọta nke usoro a dị n’elu, a ga-agbakwunye oge ọkụ ọkụ ngwa ngwa dịka olu ọkụ arụnyere (m), njupụta ọkụ na usoro ntinye:

Mgbe m ~ 1.5kg, enweghị oge agbakwunyere;

Mgbe m = 1.5 ~ 3.0kg, tinye 15.30s;

Mgbe m = 3.0 ~ 4.5kg, ọzọ 30 ~ 40s;

Mgbe m = 4.5 ~ 6.0kg, tinye 40 ~ 55s.
