Kukanganisa kwechinyakare simbi rolling process

The zvechinyakare simbi rolling muitiro ndeyokuti mabheti esimbi anorongedzerwa uye anotonhodzerwa, oendeswa kuchigayo, obva adziiswa muchoto chokupisa kuti agokungurutswa kuita simbi. Iyi nzira ine kukanganisa kuviri:

1. Mushure mokunge billet inotorwa kubva kune simbi-inoita inoenderera mberi caster, kutonhora pamubhedha unotonhorera ndeye 700-900 ° C, uye kupisa kwakadzikama kwebillet hakusi kushandiswa zvinobudirira.

2. Mushure mokunge billet inoenderera mberi ichipisa nechoto chekupisa, pamusoro pebillet icharasikirwa ne1.5% nekuda kwehuni.

Kuongorora kunobatsira kuchengetedza magetsi:

1. Kushandiswa kwemarasha kwekutanga kupisa huni inopisa billet process ndeye 80 kg / toni yesimbi (calorific value 6400 kcal / kg), iyo yakaenzana ne72 kg yemarasha akaenzana; mushure meshanduko yetekinoroji, maitiro ekushandisa simba ndeye 38 kWh patani yesimbi, iyo yakaenzana ne13.3 kg Standard marasha.

2. Kubva pakugadzirwa kwegore negore kwezvigadzirwa zvesimbi zve600,000 tani, kuchengetwa kwegore negore kwemarasha akaenzana ndiko: (72-13.3) ÷ 1000 × 600,000 tons = 35,220 matani emarasha akaenzana.

3. Simboti yekuchengetedza magetsi:

Mushure mokunge bhillet yatorwa kubva kumuchina wekukanda unoramba uripo, nzvimbo yacho ine tembiricha ye750-850, uye tembiricha yemukati inotosvika 950-1000 ° C. Imwe yemisimboti yekutanga yekudziya induction ndeye ganda mhedzisiro, inova yekuti kupisa kwesimba kunotamiswa zvishoma nezvishoma mukati kubva pamusoro pekupisa. Pamusoro, chikamu chimwe muzvitatu chemukati webillet hachidi kupisa. Zvinoenderana neakasiyana billet cross-sectional dimensions, sarudza akasiyana mafrequency kuti uwane zvirinani kudziyisa kunyatsoita.

4. Mapoinzi ekuchengetedza magetsi:

a) Iyo yakakwira simba rekushandisa chiyero chekudziya induction inogona kunge yakakwira kusvika 65 kusvika 75%, nepo yechinyakare regenerative yekupisa choto ingori 25 kusvika 30%.

b) Iyo yepamusoro oxidation ye induction heat billet inongova 0.5%, nepo moto unogadzirisa unogona kusvika 1.5-2%.
