Los ntawm 1900 mus rau 1925, phau ntawv tuav thav duab sib tsoo tshuab tau siv, roj hmab lossisvitrified sib tsoo lognrog rau txoj kab uas hla ntawm 400mm tau siv, qhov siab tshaj plaws sib tsoo fais fab yog 5 horsepower, thiab linear ceev ntawm kev sib tsoo log yog 40m / s.
Txij xyoo 1925 txog 1945, lub tshuab sib tsoo tshuab nrog lub ntiajteb txawj nqus tau tsim, thiabresinoid sib tsoo log(1924) thiab kev sib tsoo log (1937) tsim los ntawm kev siv tshuab kub nias. Txoj kab uas hla ntawm lub log sib tsoo yog 500 hli, thiab lub zog sib tsoo tau nce mus rau 15. Horsepower, sib tsoo log linear ceev yog 45 m / s.
Los ntawm 1945 txog 1960, sintered fused alumina tau siv thiab siv lub tshuab grinder. Lub zog sib tsoo mus txog 75 horsepower, lub siab ntawm lub taub hau sib tsoo yog 5000N, thiab cov kab nrawm ntawm lub log sib tsoo mus txog 63 m / s.
Los ntawm 1960 mus rau 1970, zirconium fused alumina tau siv, txoj kab uas hla ntawm lub log sib tsoo mus txog 610 hli, thiab lub tshuab sib tsoo nrog lub zog ntawm 150 horsepower tau siv, lub siab ntawm lub taub hau sib tsoo tau nce mus rau 10000N, thiab cov kab nrawm ntawm kev sib tsoo. log mus txog 83m / s.
Los ntawm 1970 mus rau 1980, txoj kab uas hla ntawm lub log sib tsoo mus txog 915 hli, thiab lub tshuab sib tsoo tshwj xeeb tau siv rau cov duab sib txawv. Lub zog mus txog 650 horsepower, thiab lub siab ntawm lub taub hau sib tsoo tau nce mus rau 30, 000N.
Los ntawm 1980 txog 2014, kev sib tsoo tshuab tau tsim sai heev. Kev sib tsoo txias tuaj yeem ua tau manually, semi-automatically thiab tag nrho tsis siv neeg, thiab kub sib tsoo tshuab cov cuab yeej thiab kub sib tsoo log tau tshwm sim, uas tuaj yeem zom cov hlau kub kub ntawm 900 degree. Cov qib ntawm automation thiab tswj cov cuab yeej siv tshuab tau raug txhim kho tas li, thiab IT technology tau muab kev koom ua ke, thiab kev ua haujlwm ntawm kev sib tsoo tshuab tau zoo dua thiab txhim kho.
