我國(guó)熱鍍鋅行業(yè)已進(jìn)入新一輪的高速發(fā)展階段。我國(guó)不銹鋼行業(yè)原材料中的鉻鎳在國(guó)外是供大于求，而在我國(guó)是供不應(yīng)求的狀況；不銹鋼則是產(chǎn)能過(guò)剩，供大于求，盈利空間波動(dòng)頻繁。隨著不銹鋼行業(yè)競(jìng)爭(zhēng)的不斷加劇。大型不銹鋼生產(chǎn)企業(yè)間并購(gòu)整合與資本運(yùn)作日趨頻繁，國(guó)內(nèi)的不銹鋼生產(chǎn)企業(yè)愈來(lái)愈重視對(duì)行業(yè)市場(chǎng)的研究，特別是對(duì)企業(yè)發(fā)展環(huán)境和客戶(hù)需求趨勢(shì)變化的深入研究。正因?yàn)槿绱?，一大批?guó)內(nèi)的不銹鋼品牌迅速崛起，逐漸成為不銹鋼行業(yè)中的**！鋼鐵工業(yè)運(yùn)行情況(一)產(chǎn)量創(chuàng)歷史高水平。2013年1-6月，全國(guó)累計(jì)生產(chǎn)粗鋼，同比增長(zhǎng)，增速較2012年同期提高。前6個(gè)月，粗鋼日均產(chǎn)量，相當(dāng)于年產(chǎn)粗鋼。其中，2月份達(dá)到歷史高的，3-6月份雖有回落，但仍保持在210萬(wàn)噸以上較高水平。分省區(qū)看，1-6月，河北、江蘇兩省粗鋼產(chǎn)量同比分別增長(zhǎng)，兩省合計(jì)新增產(chǎn)量占全國(guó)2694萬(wàn)噸增量的，另有山西、遼寧、河南和云南等省增產(chǎn)也在100萬(wàn)噸以上。分企業(yè)類(lèi)型看，1-6月，重點(diǎn)大中型鋼鐵企業(yè)粗鋼產(chǎn)量同比增長(zhǎng)，低于全國(guó)平均增幅2個(gè)百分點(diǎn)，但仍有60%的增產(chǎn)來(lái)自重點(diǎn)大中型鋼鐵企業(yè)。(二)鋼材價(jià)格低位運(yùn)行。2013年1-6月，國(guó)內(nèi)鋼材市場(chǎng)整體表現(xiàn)低迷。隨著粗鋼產(chǎn)能大幅釋放，市場(chǎng)供需陷入失衡狀態(tài)。</p><p> 鋼管廠的生產(chǎn)工藝 </p> <p> <br /> </p> <p> 鋼管廠的生產(chǎn)工藝的生產(chǎn)方法，大致分為斜軋法（孟內(nèi)斯曼法）和擠壓法。 </p> <p> 斜軋法（曼內(nèi)斯曼法）是先用斜軋輥將管壞穿孔，然后用軋機(jī)將其延伸。這種方法生產(chǎn)速度快，但對(duì)管坯的可加工性要求較高，主要適用于生產(chǎn)碳素鋼和低合金鋼管。 </p> <p> 擠壓法則是用穿孔機(jī)將管坯或鋼錠穿孔，再用擠壓機(jī)擠壓成鋼管，這種方法比斜軋法效率低，適用于生產(chǎn)**度合金鋼管。 </p> <p> 斜軋法和擠壓法都必須先將管坯或鋼錠加熱，生產(chǎn)的鋼管稱(chēng)為熱軋管。用熱加工法生產(chǎn)的鋼管有時(shí)候可根據(jù)需要再進(jìn)行冷加工。冷加工有兩種方法：一種是冷拔法，就是將鋼管通過(guò)拔管模拉拔，使鋼管逐漸變細(xì)、伸長(zhǎng)；另一種方法是冷軋法，它是將曼內(nèi)斯曼兄弟發(fā)明的熱軋機(jī)應(yīng)用于冷加工中的方法。無(wú)縫鋼管的冷加工，可以進(jìn)步鋼管的尺寸精度和加工光潔度，改善材質(zhì)的機(jī)械性能等。
