Game da bakin karfe farantin: mu yanzu sosai rare asali karfe farantin, amma saboda da babban girma, high kudin, pickling wahala, ba sauki don sufuri da sauran dalilai, kasuwa ne mafi yawan gani da bakin karfe yi lebur bakin karfe farantin. .

Bakin karfe da aka fi amfani da shi ya kasu kashi biyu:

Bakin karfe farantin nisa rarrabuwa

1, sanyi birgima bakin karfe farantin nada farantin karfe da nada farantin lebur farantin.
A, bakin karfe nada farantin karfe ne zuwa kashi 1 m, 1.219 m farantin surface, 1.5 m farantin surface.
B. The na kowa girman bakin karfe farantin ne 1 m * 2 m, 1.219 m * 2.438 m

2, zafi birgima bakin karfe farantin an kasu kashi nada farantin, lebur farantin da zafi birgima farantin.
A, bakin karfe nada farantin da aka fi amfani da surface ne 1.5 mita, 1.25 mita
B, bakin karfe farantin farantin gama gari 1.5 * 6 m, 1.8 * 6 m, 1.25 * 6 m.

Yawan abin da aka fi amfani da shi bakin karfe farantin karfe

The theoretical lissafin dabara na bakin karfe farantin:

Nauyin ka'idar (kg) = Tsawon (m) * Nisa (m) * Kauri (mm) * Musamman nauyi (yawa)

Farashin faranti: farashin coil * ainihin kauri / kauri na ka'ida + farashi mai faɗi

Misalin juyar da farashin faranti:

Ainihin kauri na daidaitaccen kauri na 2 mm bakin karfe farantin karfe shine 1.8 mm, don haka nauyin ka'idar nauyin tan 2 na farantin karfe shine ton 1.8.Idan farashin daidaitawa shine 11400 yuan / ton, farashin aunawa shine game da (2/1.80) *11400=12650 yuan/ton, (nauyi mara nauyi (1.80-2) / 2 * 100% = 10%, 11400/ (1) -9%) = 12650 yuan / ton) farashin girma na gabaɗaya yana auna, farashin yana da girma;An daidaita farashin jirgi, fiye da nauyin fam, farashin ya fi ƙasa da farashin fam.(Kasuwanci gabaɗaya za su yi amfani da wannan hanyar sasantawa, saboda farantin bakin karfe na gabaɗaya zai sami 5% na bambanci, wasu kuma har ma sun kai 30%, don haka farashin nauyi gabaɗaya zai yi girma sosai).

Nau'in lissafin bakin karfe

1, farashi = ainihin lokacin kauri ÷ lokacin farin ciki * a cikin farashi + jigilar kaya + farashin sarrafawa

2, farashin farantin coil canzawa zuwa farantin farantin = farashin girma * m kauri / kauri + lebur fee 100

3, lebur farantin farashin canji zuwa nada farantin farashin = farashin jirgin * management kauri / m kauri - lebur fee 100

4. Reel tsawon = net reel nauyi / 7.93 / reel nisa / ainihin kauri

5, algorithm na farashi tare da haraji = jimlar nauyin kaya / 1.04 (1.04 yana wakiltar maki 4 -1.07 yana nufin maki 7) misali: 10000 ton na kaya / 1.04 = 9615.3846 ton * farashin ton = sakamako misali: 1 ton na kaya = 15800 ton / 1.04 = 15192.3077 farashin ba tare da haraji ba

6. Idan aka ba da nauyin girma da farashi, nemo jimlar nauyin ƙarar = girman girman * farashin
