I. Cov txheej txheem tseem ceeb ntawm cov kub - dov seamless steel raj
1. Kev npaj thiab tshuaj xyuas: High-cov pa roj carbon zoo lossis hlau alloy steel puag ncig cov ntawv hlau raug xaiv thiab raug tshuaj xyuas nruj kom ntseeg tau tias lawv tsis muaj qhov tawg, suav nrog, thiab lwm yam tsis xws luag.
2. Cua sov: Lub billet yog pub rau hauv lub qhov cub cua sov thiab ua kom sov rau 1100 ~ 1250℃kom muab nws zoo plasticity, pab txhawb kev tho tom ntej.
3. Piercing: Lub qhov cub hluav taws kub tau dhau los ntawm ob - yob skew tho zeb (xws li lub pob zeb Mennesmann). Nyob rau hauv kev sib xyaw ua ke ntawm cov yob thiab cov mandrel, cov khoom billet yog dov rau hauv lub raj hollow. Qhov no yog ib kauj ruam tseem ceeb hauv kev tsim cov qauv "seamless".
4. Rolling thiab ncab: Lub raj xa mus rau hauv lub raj dov zeb (xws li lub raj txuas txuas txuas ntxiv los yog peb- yob lub raj dov zeb) rau ntau- dhau dov kom txo cov phab ntsa tuab thiab nce txoj kab uas hla, tswj qhov tseeb ntawm txoj kab uas hla thiab phab ntsa tuab.
5. Sizing thiab Reduction: Lub tshuab sizing lossis nro txo lub tshuab yog siv los kho cov kab hlau sab nraud ntawm cov yeeb nkab steel, kom ntseeg tau tias qhov ntev ntev raws li tus qauv yuav tsum tau ua. Qee chav nyob tuaj yeem ua tiav siab - tswj qhov tseeb ntawm ± 0.2%.
6. Kev kho cua sov: normalizing, annealing, los yog quenching thiab tempering kev kho mob yog ua raws li cov ntaub ntawv uas yuav tsum tau los txhim kho lub microstructure thiab txhim kho cov khoom siv.
7. Txias thiab Ncaj: Tom qab lub ntuj txias ntawm lub txaj taug kev ntawm lub txaj txias, cov yeeb nkab steel yog ncaj nraim kom tshem tawm qhov khoov thiab xyuas kom meej.
8. Kev Ua tiav thiab Kev Tshuaj Xyuas: Cov khoom tsis zoo ntawm qhov pib thiab qhov kawg raug tshem tawm. Kev ntsuas qhov ntev ntawm phau ntawv tau ua, thiab tsis yog- kuaj kev puas tsuaj (xws li kuaj ultrasonic thiab ntsuas tam sim no), ntsuas hydrostatic, thiab ntsuas metallographic yog ua los xyuas kom zoo ua ntej warehouses.
II. Txias Rolled / Cold Drawn Seamless Steel Yeeb Nkab Txheej Txheem (Rau Siab -Cov Khoom Siv Precision)
Tsim nyog rau me me - txoj kab uas hla, nyias- cov kav hlau uas muaj cov kav hlau uas muaj qhov yuav tsum tau muaj siab, feem ntau yog siv cov kav dej kub - dov li raw cov ntaub ntawv:
Pickling thiab lubrication → Tshem tawm oxide nplai thiab lubricates saum npoo.
Cold Rolling lossis Cold Drawing → Kos duab lossis dov ntawm chav tsev kub uas siv cov tuag los txhim kho qhov tseeb qhov tseeb thiab qhov chaw tiav.
Annealing Treatment → Tshem tawm ua hauj lwm hardening thiab restores plasticity.
Kev Ncaj Ncees, Tiav, thiab Kev Tshuaj Xyuas → Tib txheej txheem zoo li kub dov, tab sis nrog cov qauv tshuaj xyuas nruj dua.
Cov kav hlau no muaj qhov ci ntsa iab thiab cov phab ntsa tuab, thiab feem ntau siv hauv hydraulic systems, precision machinery, thiab lwm yam.
III. Extrusion Method (Suitable rau siab -Strength Alloy Steel)
Lub rhuab billet yog muab tso rau hauv lub tog raj kheej kaw extrusion, thiab kev kub siab yog siv los ntawm ib qho punch, ua rau cov hlau extruded los ntawm qhov tuag orifice. Haum rau tsim me me - txoj kab uas hla, nyuaj- mus rau -deform alloy steel kav, xws li stainless hlau thiab siab - kub alloy kav.
IV. Cov Ntsiab Cai Tswj Xyuas Zoo
Perforation Quality: ncaj qha cuam tshuam rau lub uniformity ntawm capillary phab ntsa thickness
Dimensional Accuracy: Cia siab rau qhov tiag - lub sij hawm saib xyuas los ntawm lub laser txoj kab uas hla ntsuas qhov system
Tsis yog-Kev Ntsuas Kev Ua Phem: Eddy tam sim no kev ntsuas rhiab heev tuaj yeem ncav cuag 0.1mm × 1mm kuaj pom qhov tsis raug
Kev kuaj lub cev thiab tshuaj lom neeg: suav nrog kev kuaj Brinell hardness, kuaj qhov cuam tshuam, tsom xam muaj pes tsawg leeg, thiab lwm yam.
