Te Tātai Taumaha o te Pae Porowhita Kowiri tira 304 me te Tikanga o te 0.00623

Te Mārama ki te Tauwehenga 0.00623 i roto i te Tātaitanga Taumaha Pae Porowhita

Ko te tātai e whakamahia whānuitia ana mō te whakatau tata i te taumaha ariā o tētahi pae porowhita totoka ko:

Taumaha (kg/m) = 0.00623 × Diameter × Diameter

I ahu mai tēnei tauwehenga (0.00623) i te mātotoru o te rauemi me te horahanga whakawhiti-wāhanga o te pae. Kei raro nei he whakamārama taipitopito mō te takenga mai me te whakamahinga o tēnei uara.

1. Tātai Whānui mō te Taumaha Pae Porowhita

Ko te tātai taumaha ariā taketake ko:

Taumaha (kg/m) = Horahanga Whakawhiti × Kiato = (π / 4 × d²) × ρ

• dDiameter (mm)
• ρ: Te Matotoru (g/cm³)

Kia tino ōrite ngā waeine katoa — te horahanga i roto i te mm², te mātotoru kua hurihia ki kg/mm³.

2. Tauira Whakaputa mō te Kowiri tira 304

Ko te matotoru o te maitai kore waikura 304 e tata ana ki:

ρ = 7.93 g/cm³ = 7930 kg/m³

Te whakakapi ki te tātai:

Taumaha (kg/m) = (π / 4) × d² × (7930 / 1,000,000) ≈ 0.006217 × d²

Kua porowhitahia mō te whakamahinga hangarau:0.00623 × d²

Hei tauira: Tātaitanga Taumaha Pae Porowhita Kowiri tira 904L

Ko te taumaha ariā mō ia mita o tētahi pae porowhita totoka i hangaia ki904L maitai kore waikuraka taea te tatau mā te whakamahi i te tātai paerewa e whai ake nei:

Taumaha (kg/m) = (π / 4) × d² × ρ

Kei hea:

• d= Te whānui i roto i ngā mirimita (mm)
• ρ= Te mātotoru i roto i te kg/mm³

Te mātotoru o te maitai kore waikura 904L:

ρ = 8.00 g/cm³ = 8000 kg/m³ = 8.0 × 10⁻⁶kg/mm³

Te Whakaputa Tātai:

Taumaha (kg/m) = (π / 4) × d² × 8.0 × 10⁻⁶× 1000
= 0.006283 × d²

Tātai Whakamāmā Whakamutunga:

Taumaha (kg/m) = 0.00628 × d²

(ko d te diameter i roto i te mm)

Tauira:

Mō te pae porowhita 904L me te whānui 50mm:

Taumaha = 0.00628 × 50² = 0.00628 × 2500 =15.70 kg/m

3. Whānuitanga o te tono

• He pai tēnei tauwehenga mō te maitai kore waikura 304/316, mō tētahi atu rauemi rānei he matotoru te matotoru7.93 karamu/cm³
• Ngā āhua: pae porowhita totoka, tokotoko, pereki porowhita
• Tāuru: te whānui i roto i te mm, te hua i roto i te kg/m

4. Ngā Tauwehenga Tohutoro mō Ētahi Atu Rauemi

Rauemi	Kiato (g/cm³)	Tauwehenga (kg/m)
904L Kowiri tira	8.00	0.00628
304/316 Kowiri tira	7.93	0.00623
maitai waro	7.85	0.00617
Parahi	8.96	0.00704

5. Whakamutunga

Mā te tauwehenga 0.00623 ka tere, ka pono hoki te tatau i te taumaha ariā o ngā pae porowhita maitai kore waikura. Mō ētahi atu rauemi, whakarerekētia te tauwehenga kia rite ki te mātotoru.

Mena kei te hiahia koe i ngā taumaha tika, i te ātete tapahi, i ngā pae maitai kore waikura kua whakamanahia e te MTC, tēnā whakapā mai.Saky Steel.
