Ku saabsan saxan bir ahama: hadda waxaan nahay saxan bir asalka ah oo aad dhif u ah, laakiin sababta oo ah mugga weyn, qiimaha sare, pickling adag, ma fududa in la qaado iyo sababo kale, suuqa waxaa inta badan la arki karo by duub birta ahama sida flat saxan bir ahama. .

Saxan bir ah oo inta badan la isticmaalo waxa loo qaybiyaa laba qaybood:

Kala soocidda ballaca saxan bir-la'aan ah

1, qaboojiyaha duuban oo ahama birta saxan saxan fidsan iyo saxan fidsan.
A, saxan gariiradda birta ahama waxa loo qaybiyaa 1 m,1.219 m saxan dusha, 1.5 m saxan.
B. Cabbirka caadiga ah ee saxanka birta ah waa 1 m * 2 m, 1.219 m * 2.438 m

2, saxan bir duuban oo kulul ayaa loo qaybiyaa saxan gariiradda, saxan fidsan iyo saxan duuban oo kulul.
A, saxan gariiradda birta ah oo aan caadi ahayn oogada la isticmaalo waa 1.5 mitir, 1.25 mitir
B, saxan bir ah oo aan caadi ahayn cabbirka guud 1.5*6 m, 1.8*6 m, 1.25*6 m.

Sida caadiga ah loo isticmaalo saxan bir ah saamiga walxaha

Qaaciddada xisaabinta aragtida ee saxan birta aan lahayn:

Miisaanka aragtida (kg) = Dhererka (m) * Ballac (m) * Dhumucdiisuna (mm) * Cuf-isjiid gaar ah (cufnaanta)

Qiimaha saxan fidsan: qiimaha gariiradda * dhumucda dhabta ah/ dhumucdiisuna waxay tahay + khidmad siman

Tusaalaha beddelka qiimaha saxanka:

Dhumucda dhabta ah ee dhumucda caadiga ah ee 2 mm saxan bir ah waa 1.8 mm, markaa miisaanka aragtida ee 2 tan oo saxan bir ah waa 1.8 tan.Haddii qiimaha hagaajintu uu yahay 11400 yuan/ton, qiimaha miisaanku waa qiyaastii (2/1.80) *11400=12650 yuan/ton, (miisaan taban (1.80-2) /2*100%=10%,11400/ (1) -9%) =12650 yuan/ton) qiimaha mugga guud waa miisaamayaa, qiimuhu waa sarreeyaa;Qiimaha looxa waa la hagaajiyay, marka loo eego miisaanka rodolka, qiimuhu wuu ka hooseeyaa qiimaha rodolka.(Ganacsatada guud waxay isticmaali doontaa habkan dejinta, sababtoo ah saxanka guud ee birta aan lahayn ayaa yeelan doona 5% farqiga, qaarna xitaa waxay gaari doonaan 30%, sidaas darteed qiimaha miisaanka guud ahaan wuxuu noqon doonaa mid aad u sarreeya).

Cabbirka saxanka birta ah ee duuban qabowga caadiga ah

Cabbir saxan bir ah oo kulul sida caadiga ah loo isticmaalo

Nooca xisaabinta birta aan-dhalatada lahayn

1, kharash = qaro dhab ah ÷ qaro weyn * ee qiimaha + xamuulka + khidmadaha habaynta

2, qiimaha saxanka gariiradda oo u beddelo qiimaha saxan = qiimaha mugga * dhumuc / dhumuc adag + lacag guri

3, qiimaha saxan fidsan oo u beddelo qiimaha saxanka gariiradda = qiimaha looxa * dhumucda maamulka / dhumucda adag - khidmad guri 100

4. Dhererka gariiradda = miisaanka gariiradda saafiga ah / 7.93 / ballac duurka / dhumucda dhabta ah

5, Algorithm ee qiimaha canshuurta = wadarta miisaanka alaabta /1.04 (1.04 waxay u taagan tahay 4 dhibcood -1.07 macnaheedu waa 7 dhibcood) tusaale: 10000 tan oo alaab ah /1.04=9615.3846 tan * qiimaha ton = natiijooyinka tusaale ahaan: 1 tan oo badeecad ah = 15800 tan /1.04=15192.3077 qiimo la'aan canshuur

6. Marka la eego miisaanka mugga iyo qiimaha, hel wadarta miisaanka mugga = miisaanka mugga * qiimaha
