新浪新聞資訊，記者（楊編輯）獲悉：【勝倉管業 高經理13730570531 QQ：2927372564】環氧樹脂防腐鋼管廣泛適用于飲水艙、水管道、水箱、水塔等供水設備的內壁涂裝及砂糖、谷物的貨艙內使用。也可作為游泳池、發電廠冷卻塔及成裝燃料油、汽油的金屬、混凝土的內壁涂層大口徑直縫焊管主要生產流程說明：用來制造大口徑埋弧焊直縫鋼管的鋼板進入生產線后，首先進行全板超聲波檢驗,通過銑邊機對鋼板兩邊緣進行雙面銑削，使之達到要求的板寬、板邊平行度和坡口形狀,利用預彎機進行板邊預彎，使板邊具有符合要求的曲率,在JCO成型機上首先將預彎后的鋼板【勝倉管業 高經理13730570531 QQ：2927372564】的一半經過多次步進沖壓，壓成"J"形，再將鋼板的另一半同樣彎曲，壓成"C"形，*形成開口的"O"形,使成型后的直縫焊鋼管合縫并采用氣體保護焊（MAG）進行連續焊接,采用縱列多絲埋弧焊（*多可為四絲）在直縫鋼管內側進行焊接,采用縱列多絲埋弧焊在直縫埋弧焊鋼管外側進行焊接,對直縫焊鋼管內外焊縫及焊縫兩側母材進行100%的檢查,X射線檢查,對內外焊縫進行100%的X射線工業電視檢查，采用圖象處理系統以保證探傷的靈敏度,對埋弧焊直縫鋼管全長進行擴徑以提【勝倉管業 高經理13730570531 QQ：2927372564】高鋼管的尺寸精度，并改善鋼管內應力的分布狀態,水壓試驗：在水壓試驗機上對擴徑后的鋼管進行逐根檢驗以保證鋼管達到標準要求的試驗壓力，該機具有自動記錄和儲存功能,將檢驗合格后的鋼管進行管端加工，達到要求的管端坡口尺寸,再次逐根進行超聲波檢驗以檢查直縫焊鋼管在擴徑、水壓后可能產生的缺陷,對擴徑和水壓試驗后的鋼管進行X射線工業電視檢查和管端焊縫拍片,進行此項檢查以發現管端缺陷,合格后的鋼管根據用戶要求進行防腐和涂層。【勝倉管業 高經理13730570531 QQ：2927372564】 鋼廠的經營風險主要【勝倉管業 高經理13730570531 QQ：2927372564】來自成品和原料的價格波動。所以，部分鋼廠和鋼管廠設立了期貨部，利用鐵礦石、焦煤、焦炭、熱卷、螺紋鋼期貨對沖上述風險。
 “現貨貨源緊缺、采購困難時，我們會考慮在期貨市場適當買入，構建虛擬原料庫存。待現貨采購到位，再進行期貨平倉。”上述鋼廠期貨部門相關人士說。 期貨日報記【勝倉管業 高經理13730570531 QQ：2927372564】者發現，企業不僅利用期貨工具進行資源調配，還利用基差貿易助力企業發展。 據某大型鋼廠負責人介紹，該企業主要產品有熱軋、冷軋、中板、螺紋鋼，且自有鐵礦礦山，自給率在50%。目前，鐵礦石價格在原料市場中相對低廉，盡管擁有鐵【勝倉管業 高經理13730570531 QQ：2927372564】礦資源，也不占優勢。鋼廠鐵礦石采購以進口、自產、周邊礦為主。結合自身需求，他們去年嘗試了鐵礦石基差貿易，以鐵礦石1805合約為標的合約，點價期是2017年12月29日—2018年1月29日。最終，以540元/噸的價格平倉500手，順利完成套保。 田遠鵬表示，目前，鋼廠和鋼管廠普遍都在利用期貨工具進行風險管理，只是各家的利用程度存在差異。部分企業停留在對原料的套保上，也有部分企業對基差貿易進行了創新。通常，基差貿易是由賣方確定基差，由買方點價。而在某企業的業務中，基于雙方的業務合作意向，由作為買方的鋼廠讓渡點價權，獲得基差制定權，充分體現了基差貿易的靈活性。 基差貿易與鐵礦石現貨貿易中使用的“現貨指數+基差”類似，符合實體企業的貿易習慣和經營需求。通過大量產業客戶和投資者公開交易生成的期貨價格更為公開公正透【勝倉管業 高經理13730570531 QQ：2927372564】明，鐵礦石期貨市場良好的流動性也有利于企業進行點價和對沖。 除了期貨業務，也有鋼廠嘗試了場外期權業務。今年4月以來，鐵礦石供需相對平衡，價格波動明顯弱化，場外期權權利金處于合理水平，在此期間買入鐵礦石看漲期權，以較低的費用就可以鎖定原料價格上漲的風險。 “原料套保和基差貿易對鋼廠穩定收益、提升經營及生產能力具有積極意義。”田遠鵬說。
 The risk of steel mills mainly comes from the price fluctuation of finished products and raw materials. Therefore, some steel mills and steel pipe mills have set up futures departments, using iron ore, coking coal, coke, hot coil, screw steel futures to hedge the above risks. According to the futures Department of a steel plant, the normal state of the enterprise's own coking plant can achieve self-sufficiency, but since the second half of last year, due to good profits, they restarted a small blast furnace, so that coke supply gap. At present, it purchases a small amount of secondary coke in Hebei and Shanxi, but because of the high price and insufficient purchasing power, the coke plant inventory can be maintained for 2-3 days. Coking coal is mainly based on long association, and the supply is relatively stable. However, due to worries about transport capaci【勝倉管業 高經理13730570531 QQ：2927372564】ty and weather caused by tight supply, the company formulated a winter storage plan.
 Reporters of Futures Daily found that enterprises not only use futures tools for resource allocation, but also use the basis trade to promote enterprise development. According to the person in charge of a large steel plant, the main products of the enterprise are hot-rolled, cold-rolled, medium plate, screw steel, and its own iron mine, self-sufficiency rate of 50%. At present, the price of iron ore in the raw material market is relatively low, despite the iron ore resources, is not dominant. Iron ore purchase in steel mills is mainly imported, self produced and surrounding mines. Combined with their own needs, they tried iron ore base trade last year, with iron ore 1805 contract as the subject of the contract, the price period is December 29, 2017 - January 29, 2018. Finally, the 500 guarantees were closed at the price of 540 yuan / ton, which successfull【勝倉管業 高經理13730570531 QQ：2927372564】y completed the hedging. At present, steel mills and steel pipe mills are generally using futures tools for risk management, but there are differences in the degree of utilization. Some enterprises remain on the hedging of raw materials, and some enterprises have made innovations in the basis trade. Usually, the basis trade is determined by the seller and the price is determined by the buyer. In the business of an enterprise, based on the intention of business coopera【勝倉管業 高經理13730570531 QQ：2927372564】tion between the two sides, the steel mill as the buyer transfers the point price right and obtains the base deviation formulation right, which fully embodies the flexibility of base trade. _basis trade is similar to the "spot index + base difference" used in iron ore spot trade, which conforms to the trade habits and operational needs of the real enterprises. The futures prices generated by a large number of industrial customers and investors are more open, fair and transparent, and the good liquidity of iron ore futures market is also conducive to enterprises to price and hedge. Besides the futures business, steel companies also tried out the options business. Since April of this year, the supply and demand of iron ore has been relatively balanced, the price fluctuation has been weakened obviously, and the OTC option premium is at a reasonable level. During this period, the risk of rising raw material prices can be locked in by buying iron ore call options at a lower cost.【勝倉管業 高經理13730570531 QQ：2927372564】 “原料套保和基差貿易對鋼廠穩定收益、提升經營及生產能力具有積極意義。” Tian Yuanpeng said.  |
