寶鋼擬投近190億建設(shè)湛江鋼鐵三高爐系統(tǒng)項(xiàng)目【勝倉(cāng)管業(yè) 高經(jīng)理13730570531 QQ:2927372564】
寶鋼股份28日發(fā)布的公告顯示,公司擬建設(shè)寶鋼湛江鋼鐵三高爐系統(tǒng)項(xiàng)目。
據(jù)了解,湛江鋼鐵基地一、二高爐系統(tǒng)建成后,充分發(fā)揮出運(yùn)營(yíng)成本、生產(chǎn)技術(shù)水平、勞動(dòng)效率等多方面優(yōu)勢(shì),快速實(shí)現(xiàn)盈利,體現(xiàn)出極強(qiáng)的綜合競(jìng)爭(zhēng)力。為進(jìn)一步鞏固和強(qiáng)化寶山鋼鐵股份有限公司(以下簡(jiǎn)稱(chēng)“公司”)在優(yōu)質(zhì)碳鋼扁平材領(lǐng)域的領(lǐng)先地位,提升公司業(yè)績(jī),擬建設(shè)寶鋼湛江鋼鐵三高爐系統(tǒng)項(xiàng)目(以下簡(jiǎn)稱(chēng)“本項(xiàng)目”)。
本項(xiàng)目在充分利用湛江鋼鐵一、二高爐系統(tǒng)預(yù)留設(shè)施基礎(chǔ)之上,適當(dāng)擴(kuò)建原料碼頭、原料場(chǎng)、燒結(jié)機(jī)、焦?fàn)t、高爐、轉(zhuǎn)爐等裝備,生產(chǎn)低成本、高品質(zhì)的鋼坯。【勝倉(cāng)管業(yè) 高經(jīng)理13730570531 QQ:2927372564】
本項(xiàng)目新建具備超高強(qiáng)鋼生產(chǎn)能力的熱軋單元和冷軋單元各1個(gè);其中冷軋單元結(jié)合上海地區(qū)的產(chǎn)線(xiàn)調(diào)整,考慮搬遷部分上海不銹的冷軋產(chǎn)線(xiàn)。本項(xiàng)目年新增鐵水402萬(wàn)噸、鋼水360萬(wàn)噸、熱軋產(chǎn)品450萬(wàn)噸、冷軋產(chǎn)品166萬(wàn)噸。
項(xiàng)目建成后湛江鋼鐵總規(guī)模為年產(chǎn)鐵水1,225萬(wàn)噸、鋼水1,252.8萬(wàn)噸、鋼材1,081萬(wàn)噸。經(jīng)初步預(yù)測(cè),項(xiàng)目總投資188.5億元;參照湛江鋼鐵近三年生產(chǎn)實(shí)績(jī)測(cè)算的財(cái)務(wù)內(nèi)部收益率約為11.9%。
Global News, September 6, learned: [Senior Manager of Shengkuang Pipe Industry 13730570531 QQ: 2927372564] Strengthened grade TPEP anticorrosive steel pipes were tested. The roughness of the inner surface of the pipes affected more than the area of local bulge (such as spiral welds or longitudinal welds, even including inner ring welds). Double. Production and manag【勝倉(cāng)管業(yè) 高經(jīng)理13730570531 QQ:2927372564】ement of spiral welded pipe production can reflect the advantages of high quality and high efficiency. The production capacity of a spiral welded pipe mill is equal to 5-8 vertical welded pipe equipments. It will be a heavy task to make the production lines of several coiled pipe equipments reach the same production standard, that is, according to the unified production process specification and quality assurance system to meet the welding quality requirements and pipe manufacturing grade. The production capacity of multi head is higher than that of engineering management and quality supervision. The difference of operation s【勝倉(cāng)管業(yè) 高經(jīng)理13730570531 QQ:2927372564】kills, quality awareness, distribution points and control procedures among the operators of several straight-seam pipe rolling units and corresponding welding equipment will bring about many difficulties in production management, schedule, inspection and acceptance, delivery and coordination, which will easily lead to confusion in management and coordination and confusion among manufacturers and construction units. The quality 【勝倉(cāng)管業(yè) 高經(jīng)理13730570531 QQ:2927372564】of buck passing. It often reaches the standard at the scene. After handling and knocking, the magnetic field is over standard. The reason is that the magnetic domain inside the large diameter spiral steel tube is not very stable without magnetic training. The standard of how to demagnetize the large diameter spiral steel pipe is below 30GS. The demagnetization system of HT30D steel pipe can stabilize the remanence of the steel pipe to about 10GS, so as to avoid the remanence rebound during the later transportation. Slag floating on the surface of the metal pool, on the one hand, can protect the weld metal, prevent air pollution, and produce physical and chemical reactions with the molten metal, improve the weld metal and properties; on the other hand, can also make the weld metal cooling slowly.【勝倉(cāng)管業(yè) 高經(jīng)理13730570531 QQ:2927372564】
