Steelmaking thiab Nruam Casting:

Cov hlau yog melted nyob rau hauv lub cub tawg thiab refined kom ua tiav cov tshuaj muaj pes tsawg leeg uas yuav tsum tau rau lub zog thiab weldability. Nws yog tam sim no nrum nrum rau hauv slabs los yog ingots.

Reheating thiab Rolling:

Cov khoom cam khwb cia yog reheated thiab dov rau hauv daim hlau los ntawm ntau qhov kev hla, nrog kev tswj dov thiab txias kom tsim tau qhov xav tau microstructure thiab txhua yam khoom.

Kev kho cua sov:

Cov phaj feem ntau ua rau normalizing (thiab qee zaum tempering), uas muaj cua sov rau qhov ntsuas kub, tuav, thiab cua txias kom ua kom cov nplej zoo dua thiab txhim kho toughness.

Straightening thiab Surface Conditioning:

Tom qab kev kho cua sov, daim hlau raug ncaj kom tshem tawm qhov tsis sib haum xeeb thiab ua tiav los ntawm kev txhaj tshuaj blasting lossis cov txheej txheem zoo sib xws los ntxuav qhov chaw thiab tshem tawm cov nplai.

Kev tshuaj xyuas thiab kuaj:

Cov phaj raug tshuaj xyuas qhov tseeb qhov tseeb thiab qhov zoo ntawm qhov chaw, thiab kuaj (xws li kuaj ultrasonic, tensile, cuam tshuam, thiab hardness tests) kom paub meej tias ua raws li tus qauv.

Txiav thiab Fabrication Npaj:

Cov ntawv pom zoo raug txiav kom loj thiab npaj rau kev ua haujlwm ntxiv, suav nrog kev ua haujlwm, drilling, thiab ntug lossis bevel npaj.

Tsim thiab Vuam:

Cov phaj yog tsim rau hauv cov duab thiab welded siv cov txheej txheem tsim nyog. Preheating thiab post-weld heat treatment tej zaum yuav siv tau raws li qhov xav tau los xyuas kom meej lub suab welds thiab kev ua tau zoo nyob rau hauv siab - qhov kev pabcuam kub siab.

Vim li cas thiaj xaiv peb:
Koj tuaj yeem tau txais cov khoom zoo meej raws li qhov koj xav tau ntawm tus nqi tsawg kawg nkaus.

Peb kuj muab Reworks, FOB, CFR, CIF, thiab qhov rooj rau qhov rooj tus nqi xa khoom. Peb xav kom koj ua deal rau shipping uas yuav zoo heev.

Cov ntaub ntawv uas peb muab yog muaj tseeb tiag, txoj cai los ntawm raw cov ntaub ntawv xeem daim ntawv pov thawj mus rau qhov kawg dimensional nqe lus.

Peb lav muab cov lus teb tsis pub dhau 24 teev (feem ntau hauv tib lub sijhawm)

Koj tuaj yeem tau txais cov khoom hloov pauv, zeb xa khoom nrog txo lub sijhawm tsim khoom.

Peb tau mob siab rau peb cov neeg siv khoom. Yog tias nws yuav tsis tuaj yeem ua tau raws li koj cov kev xav tau tom qab kuaj xyuas tag nrho cov kev xaiv, peb yuav tsis ntxias koj los ntawm kev cog lus tsis tseeb uas yuav tsim kev sib raug zoo rau cov neeg siv khoom.
