High hardness Tungsten Carbide Cov menyuam ntiv nplhaib rau Kev Kub Ceev Rolling ntawm Alloy Steel Bars

Carbide roller rings tau yug los nrog kev txhim kho ntawm cov hlau ua kev lag luam tom qab lub advent ntawm hmoov metallurgy technology nyob rau hauv 1909. Txij li thaum cov kev taw qhia ntawm cemented carbide hlau kos duab tuag nyob rau hauv lub teb chaws Yelemees nyob rau hauv 1918, nws tau txhawb kev tshawb fawb ntawm cemented carbide nyob rau hauv ntau lub teb chaws, thiab yob. rau ntau lub hom phiaj kuj tau tshwm sim ib qho tom qab.Txawm li cas los xij, daim ntawv thov loj ntawm cov cemented carbide rollers tuaj tom qab xyoo 1960. Hauv xyoo 1964, kev yug ntawm thawj high-speed twist-free wire rod rolling mill ntawm Morgen Company tau nce qhov ceev ntawm cov hlua hlau los ntawm 4 zaug.Txij li thaum lub tshuab ua tiav tiav ua haujlwm ntawm kev kub ceev thiab kev ntxhov siab, cov cam khwb cia hlau chais thiab cov cuab yeej steel chais muaj qhov tsis zoo hnav tsis zoo, lub rolling groove lub neej luv luv, thiab kev kho thiab thauj khoom thiab tshem tawm ntawm cov yob yog nquag heev, uas cuam tshuam. qhov ua tau zoo ntawm cov dov zeb thiab tsis haum rau kev ua tiav cov khoom siv dov.cov kev xav tau, yog li nws tau hloov los ntawm kev sib xyaw carbide rollers.Muaj ntau tshaj 200 lub hauv paus mills hauv ntiaj teb, uas siv ntau pua tons ntawm cemented carbide dov txhua xyoo.
