據(jù)某鋼廠期貨部門相關(guān)人士介紹，企業(yè)自有焦化廠，正常情況可實(shí)現(xiàn)自給自足，但去年下半年以來，由于利潤良好，他們重啟了1座小高爐，以至于焦炭供應(yīng)出現(xiàn)缺口。目前，其在河北、山西采購少量二級(jí)焦炭，但由于價(jià)格偏高，采購動(dòng)力不足，焦炭廠內(nèi)庫存保持2—3天即可。焦煤則以長協(xié)為主，供應(yīng)相對(duì)穩(wěn)定。不過，由于擔(dān)心運(yùn)力和天氣原因造成貨源緊張，企業(yè)制定了冬儲(chǔ)計(jì)劃。

田遠(yuǎn)鵬表示，目前，鋼廠和鋼管廠普遍都在利用期貨工具進(jìn)行風(fēng)險(xiǎn)管理，只是各家的利用程度存在差異。部分企業(yè)停留在對(duì)原料的套保上，也有部分企業(yè)對(duì)基差貿(mào)易進(jìn)行了創(chuàng)新。通常，基差貿(mào)易是由賣方確定基差，由買方點(diǎn)價(jià)。而在某企業(yè)的業(yè)務(wù)中，基于雙方的業(yè)務(wù)合作意向，由作為買方的鋼廠讓渡點(diǎn)價(jià)權(quán)，獲得基差制定權(quán)，充分體現(xiàn)了基差貿(mào)易的靈活性。
基差貿(mào)易與鐵礦石現(xiàn)貨貿(mào)易中使用的“現(xiàn)貨指數(shù)+基差”類似，符合實(shí)體企業(yè)的貿(mào)易習(xí)慣和經(jīng)營需求。通過大量產(chǎn)業(yè)客戶和投資者公開交易生成的期貨價(jià)格更為公開公正透【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】明，鐵礦石期貨市場(chǎng)良好的流動(dòng)性也有利于企業(yè)進(jìn)行點(diǎn)價(jià)和對(duì)沖。
除了期貨業(yè)務(wù)，也有鋼廠嘗試了場(chǎng)外期權(quán)業(yè)務(wù)。今年4月以來，鐵礦石供需相對(duì)平衡，價(jià)格波動(dòng)明顯弱化，場(chǎng)外期權(quán)權(quán)利金處于合理水平，在此期間買入鐵礦石看漲期權(quán)，以較低的費(fèi)用就可以鎖定原料價(jià)格上漲的風(fēng)險(xiǎn)。

According to Sina News, the reporter (Yang Editor) learned that the epoxy resin anticorrosive steel pipe is widely used in drinking water tanks, water pipes, water tanks, water towers and other water supply equipment, as well as in the use of sugar and cereal cargo hold. It can also be used as swimming pool, cool【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】ing tower of power plant and inner wall coated large diameter straight seam welded pipe of fuel oil, gasoline and concrete. The main production process of the steel plate used to manufacture large diameter submerged arc welded straight seam steel pipe is explained. After entering the production line, the whole plate is inspected by ultrasonic wave, and the two edges of the steel plate are inspected by milling machine. Double-sided milling, so as to meet the requirements of the width of the plate, edge parallelism and groove shape,【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】 the use of pre-bending machine edge pre-bending, so that the edge of th【勝倉管業(yè) 高經(jīng)理13730570531 QQ：2927372564】e plate has the required curvature, in the JCO molding machine, the first half of the pre-bended steel plate through a number of stepping stamping, pressing into the "J" shape, and then the other half of the plate bending the same, pressing into the "C" shape. 8727 The base metal on both sides of the weld is inspected by 100% X-ray, the inside and outside welds are inspected by 100% X-ray industrial television, and the sensitivity of inspection is guaranteed by image processing system. The full length of submerged arc welded straight-seam steel pipe is enlarged to improve the dimensional accuracy of the pipe and the stress distribution in the pipe. The test machine inspects the enlarged steel pipe one by one to ensure that the steel pipe meets the test pressure required by the standard. The machine has the function of automatic recording and storage.

Possible defects after the expansion and hydraulic test of the steel pipe X-ray industrial television inspection and tube end weld photography, this inspection to find the tube end defects, qualified steel pipe according to user requirements for corrosion protection and coating.
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(yè) 高經(jīng)理13730570531 QQ：2927372564】ty and weather caused by tight supply, the company formulated a winter storage plan.
10 When the spot purchase is in place, the futures will be closed. The steel futures Department said.
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(yè) 高經(jīng)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(yè) 高經(jīng)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(yè) 高經(jīng)理13730570531 QQ：2927372564】
