▲ Ua ntej, txiav cov rail hlau raws li qhov loj me (cov hlau rail yog resistant rau hnav thiab muaj zog txaus thiab toughness);
▲ Cov hlau rail yog rhuab ntawm qhov kub kub hauv qhov cub;
▲ Cov hlau khiav liab yog muab tso rau ntawm lub forging xovxwm thiab forged ntau zaus. Muab tso rau hauv lub tshuab dov, thiab deform tom qab dov ob peb zaug;
▲ Reheat lub dov rail hlau nyob rau hauv lub cub tawg, muab cov liab rail hlau rau ntawm forging xovxwm rau forging ua, thiab ces muab tso rau hauv lub dov xovxwm, thiab tom qab dov nws ob peb zaug, nws yuav ua tau ib tug ntev steel phaj; (nco ntsoov tias cov txheej txheem xav tau ob zaug. Cua sov forging)
▲ Nws dhau los ua ib lub phaj ntev ntev tom qab ob peb zaug ntawm dov, thiab cov phaj hlau tau muab tso kom zoo tom qab txias;
▲ Cov hlau phaj yog muab tso rau hauv lub tshuab xuas nrig ntaus, thiab cov hlau shovel yog xuas nrig ntaus tawm;
▲ Tom qab cov shovel yog rhuab ntawm qhov kub thiab txias, nws yog muab tso rau hauv lub tshuab rau stamping thiab sib sau;
▲ Tom qab cov shovel yog rhuab ntawm qhov kub thiab txias, nws yog muab tso rau hauv lub tshuab rau stamping thiab sib sau;
▲ Kev kho deg ntawm cov shovel. Kev kho deg txheej txheej steel shovel yog anti-xeb ntawm cov khoom nto kho kom zoo nkauj;
▲ Ntim thiab khaws cov shovel steel. Lub taub hau steel shovel thiab shovel ncej tau ntim thiab khaws cia nyias;
