Hlau txhajyog ib qho tseem ceeb ntawm kev siv tshuaj tua blasting thiab workpiece ntxiv dag zog. Nws qhov zoo ncaj qha cuam tshuam rau kev ua haujlwm, kev pabcuam lub neej thiab kev kho qhov chaw. Koj tuaj yeem txiav txim siab sai sai ntawm nws qhov zoo los ntawm cov tsos, hardness, muaj pes tsawg leeg thiab durability.
High -zoo steel txhaj yogtsis tu ncua nyob rau hauv cov duab, siab puag ncig, uniform loj, nrog ib tug du nto tsis muaj burrs los yog kab nrib pleb, thiab ib tug txawm tsaus grey metallic luster. Tsis zoo-cov yeeb yaj kiab zoo feem ntau tsis sib xws, tiaj tus, hollow, plua plav thiab tsis huv, nrog cov dej tsis zoo.
Hardness yog qhov tseem ceeb. Tsim nyog txhaj tshuaj steel feem ntau muaj ib Hardness ntawm HRC 40-50,nrog balanced hardness thiab toughness. Nws tsis tawg yooj yim nyob rau hauv kev cuam tshuam thiab ua kom ruaj khov kev ua haujlwm. Tshaj -hnyav txhaj tshuaj tawg sai sai nrog hnav siab; tshaj -mos txhaj tshuaj tsis muaj txiaj ntsig ntawm kev tshem tawm xeb thiab tuaj yeem ua rau khawb tsis sib xws.
Tshuaj muaj pes tsawg leeg txiav txim siab durability. Hwm hlau txhaj tshuaj muaj cov ntsiab lus ntawm cov pa roj carbon tsawg, zoo silicon thiab manganese piv, thiabtsis tshua muaj sulfur thiab phosphorus impurities, nrog ib tug ntom microstructure thiab tsim nyog ceev. Inferior steel txhaj tshuaj muaj ntau dhau impurities thiab xoob qauv, uas yooj yim tig mus rau hmoov thaum siv, ua rau hnyav plua plav paug thiab noj sai.
Ib qho yooj yim ntawm - qhov chaw sim ua haujlwm zoo: coj mus rhaub ob peb pellets tiv thaiv lub phaj hlau. Kev txhaj tshuaj zoo steel ua rau lub suab meej thiab bounces zoo; maj mam ntaus nws nrog rauj, thiab nws deforms ntau dua li tawg. Hauv kev siv tiag tiag, siab- zoo tshaj cov hlau txhaj tshuaj muaj lub neej ua haujlwm ntev, tsis tshua muaj plua plav thiab kev tu zoo, thaum tsis zoo- kev txhaj tshuaj zoo ua rau ntau qhov tawg, yuav tsum tau hloov tas li thiab nce nqi tag nrho.
Thaum yuav khoom, xaiv cov khoom lag luam los ntawm cov tuam txhab tsim khoom nrog cov ntaub ntawv soj ntsuam hauv tebchaws. Ua ntejroundness, haum hardnessthiab purity los txo cov nqi thiab xyuas kom ruaj khov kho qhov zoo.
