Kev Tshwj Xeeb yog qhov sib txawv ntawm cov txheej txheem tsim khoom rau kev tsim khoom (kho) ntawm cov khoom. Nyob rau tib lub sijhawm, ib chav tsev tshwj xeeb lossis kev ua haujlwm tshwj xeeb raug xa mus rau ib qho chaw ua haujlwm (rhiav, ntu, txoj haujlwm). Kev suav ntawm cov coefficient ntawm kev tsim tshwj xeeb ntawm kev tsim khoom yog qhov tsim nyog rau kev txheeb xyuas hom kev tsim khoom thiab qib kev tsim kho thev naus laus zis ntawm kev lag luam tag nrho.

Kev tshwj xeeb rau cov tshuab

Nws muaj kev sib raug zoo ntawm cov coefficient ntawm kev tshwj xeeb thiab cov yam ntxwv ntawm cov tshuab tsim khoom. Yog li, rau ntau hom, tshwj xeeb hauv kev ua haujlwm tshwj xeeb, uas tau rov ua dua lub sijhawm, yog yam ntxwv. Txhawm rau ua qhov no, yuav tsum ua raws li cov xwm txheej hauv qab no:

∑N_i × t_i=F_d,

• qhov twg N_{i - lub ntim (kev pab cuam) ntawm kev tsim cov ntu i-th rau lub sijhawm, units;}
• t_{i - sijhawm ua haujlwm, teev;}
• F_{d - siv tau nyiaj txhua xyookhoom siv, teev.}

Hauv cov kab ke, kev tshwj xeeb yuav tshwm sim hauv qee qhov kev ua haujlwm tsawg, uas tib lub sijhawm hloov pauv hauv qhov kev txiav txim. Cov xwm txheej yuav ua raws li daim ntawv:

∑N_i× t_i ≦ F_d

Xaiv coefficient of specialization

Kev kawm txog cov yam ntxwv ntawm kev txhim kho tshwj xeeb ntawm kev lag luam lossis ib tus neeg ua haujlwm yog ua los ntawm ntau tus yam ntxwv:

• tshwj xeeb ntim khoom tshwj xeeb (tsis siv neeg) ntawm lub tuam txhab;
• ntau cov cuab yeej siv hauv kev tsim khoom loj;
• feem ntawm cov txheej txheem tshwj xeeb hauv cov txheej txheem tag nrho;
• feem pua ntawm kev sib koom ua ke hais txog chav tsev thiab qhov chaw;
• feem pua ntawm cov txheej txheem thev naus laus zis (homogeneous).

Kev tshwj xeeb coefficient tuaj yeem txiav txim siab li no:

К_с =∑К_i ÷ n_i,

• qhov twg K_{i - tus naj npawb ntawm cov haujlwm hauv i-th txoj haujlwm (chaw ua haujlwm);}
• _{i - tus naj npawb ntawm txoj haujlwm.}

Influence of processing technology

Hauv kev xyaum, hom kev tshwj xeeb ntawm kev lag luam lossis nws feem cuam tshuam rau kev txiav txim siab ntawm coefficient ntawm kev tshwj xeeb. Feem ntau ntawm cov txheej txheem thev naus laus zis siv, raws li txoj cai, yog ib leeg lossis pab pawg.

Ib yam khoom yog ua raws li qhov chaw ntawm tib lub npe, qhov ntev thiab kev tsim khoom. Qhov no homogeneity pubkev siv cov cuab yeej tshwj xeeb thiab cov cuab yeej siv, tso cai rau koj kom ua tiav cov ntsiab lus siab tshaj plaws ntawm cov txheej txheem. Cov pwm no tau yoog zoo rau cov tshuab tsim khoom loj.

Cov txheej txheem pab pawg yog raws li qhov zoo sib xws ntawm kev ua haujlwm ntawm cov ntsiab lus thiab daim ntawv, tab sis yog cov khoom siv nrog cov qauv tsim sib txawv. Daim ntawv no ntawm kev tsim kho tshuab ua rau nws muaj peev xwm hloov cov cuab yeej hauv cov txheej txheem ntawm kev ua cov khoom, los ntawm kev siv cov khoom nyuaj. Txhua qhov ntawm cov khoom no yog txuam nrog cov cuab yeej tshwj xeeb - sib tsoo, tig, milling, thiab lwm yam. Cov cuab yeej siv pab pawg tsim nyog rau kev tsim khoom loj, tso cai rau koj los ua kom cov txheej txheem thiab cov koom haum thiab tsim cov txheej txheem ntau lawm (xws li cov txheej txheem siab dua).

Coefficient suav nrog rau hauv tus account technology

Tus coefficient ntawm kev tshwj xeeb yog txiav txim siab raws li cov qauv tsim khoom uas twb muaj lawm ntawm lub tuam tsev txiav txim siab (section) ntawm qhov system:

• rau txhua qhov kev faib - yog tias siv cov khw nrog cov ncauj lus qhia (kev ua haujlwm ntawm cov khoom sib xws ntawm cov ntsiab lus sib txawv) - trolley khw, khw log;
• suav yog ua tiav rau lub tswv yim dav dav ntawm kev lag luam - yog tias cov kev cob qhia tau tsim los ntawm kev siv tshuab (kev ua haujlwm tib yam ntawm cov pob ntawm cov qauv tsim sib txawv) - galvanic, vuam, sib dhos.

Thaum ib lub lag luam siv ob qho tib si ntawm cov thev naus laus zis no, cov qauv tshwj xeeb coefficient yuav tsum coj mus rau hauv tus account lub chaw thau khoom (cov khoom siv) thiab cov txheej txheem ua tiav.

BHauv qhov no, tus coefficient tau txhais raws li hauv qab no:

K_co =K_ze × (K_zed / K _oz) + K_zg × (K_zgr / K_oz),

• qhov twg K_{co yog tus coefficient ntawm kev tshwj xeeb ntawm tag nrho cov kab ke;}
• К_ze and К_{зг - kev ua haujlwm coefficients rau ib leeg thiab pab pawg thev naus laus zis;}
• К_zed and К_{зgr - thauj khoom ntawm cov haujlwm ua haujlwm, feem, raws li kev ua haujlwm sib txawv (ib leeg thiab pab pawg);}
• К_{oz - nruab nrab load yam ntawm txoj haujlwm (txoj haujlwm).}

Zaj lus

Raws li tuaj yeem pom los ntawm kev tshuaj xyuas, kev tshwj xeeb muaj ntau hom thiab kev siv. Nws manifests nws tus kheej ntawm txhua theem ntawm kev tsim khoom thiab muaj kev cuam tshuam ncaj qha rau kev txhim kho ntxiv ntawm kev lag luam dhau sijhawm. Kev sib sib zog nqus qhov tshwj xeeb ntawm txhua theem ntawm cov txheej txheem tsim khoom ua rau nws tuaj yeem txav mus rau cov khoom lag luam zoo tshaj plaws thiab kev tswj hwm zoo tshaj plaws.
