Однако, судя по поставкам импортной руды после Национального дня, из - за быстрого сниженияС ростом цен на железную руду индекс цен на железную руду упал ниже долларов, что снизило энтузиазм в отношении поставок импортной руды. Кроме того, экологические инспекции стали более строгими, и предложение некоторых отечественных шахт сильно пострадало. В настоящее время темпы ввода в эксплуатацию отечественных шахт на процентных пунктов ниже предыдущего пика и могут еще больше снизиться в будущем.The copper bar market declined steadily this week, with a decline of - yuan. Due to low pig iron inventory, some steel mills in Jiangxi have resumed purchasing recently, but the purchasing volume is not large. The purchase price of pig iron in Yunnan steel plants was slightly increased to ensure the purchase volume due to the low purchase price of pig iron in the early stage. Recently, the steel market has been in shock and adjustment, and the merchants are unstable. Steel mills in Hebei, Tianjin and other regions have stopped producing pig iron for steelmaking. Now, it is mainly expected to make inquiries. However, due to the lower price of raw materials, the price of iron mills has been lowered.Advantages: good quality, fine structure, high density, high pressure resistance, large bending deformation, suitable for frequent cold and heat exchange, large temperature difference in working environment, and large size copper tube can be produced.

On November , the market price of Cangzhou copper BAR was stable. According to the monitoring data of Lange Iron and Steel & S cloud business platform, the market price of * mm cold drawn steel produced in Linyi is yuan, the market price of * mm in Linyi is yuan, the market price of * mm in Jianlong is yuan, the market price of * mm, in Yuanhua is yuan, the market price of * mm in Juneng is yuan the market of price of * in Steotou is yuan, And the market price of * mm in Juneng thermal expansion is yuan.Dissolved oxygen in water is a major factor in copper pipe corrosion.In terms of steel billets: at : , some steel billets in Changli were reduced by , and the current carbon square billets were delivered with tax of yuan. After the th National Congress of the Communist of China, the market had doubts about the uncertainty of environmental production restriction and was still waiting for a clearer direction. Therefore,Чиба321 Нержавеющая сталь, it can be seen that at this stage, there was no unilateral market for either futures or cash, and there was no definite pattern of ups and downs. According to the monitoring data of Lange Iron and Steel & S cloud business platform, as of the time of publications, B yuan / ton; Jiujiang х хщщщ to Tianjin yuan / ton; The arrival price of Xinji Aosen тд is yuan / ton, and that of B steel is yuan / ton; Jiyuan yuan / ton, B steel yuan / ton; Fulen yuan / ton yuan / ton, B steel yuan / ton. путевой обход , высокая себестоимость производства, высокая цена. Процесс экструзии медных труб в настоящее время является стабильным и отличным методом производства медных труб в стране и за рубежом. Только медные трубы, произведенные в этом процессе, более подходят для области отопления, что является будущим направлением развития медной трубной промышленности.At present the fundamentals faced by the domestic copper BAR market are still mixed. On the one hand, the market supply is expected to shrink, but on the other hand, the northern market has entered the off - season of demand, and the market th with. S expectation of future demand is pessimistic. In the short term, domestic steel prices will enter the operating track of range consolidation. To sum up, considering the current situation of demand and inventory in the steel market, it is difficult for the steel market to make a breakthrough. As the th National Congress of the Communist of China is approaching, environmental protection phenomena such as steel mills are still going on, and black series specculation is still taking place. But personally, the fluUation range of the market in this region is limited, and businesses can operate flexibly on a short - term basis, and the shipment transaction is * * * *.Из трех методов производства медных труб наиболее распространенным является окисление. Потому что медные трубы могут быть изготовлены до тех пор, пока металлическая медь окисляется анодом и ионы меди анода прикрепляются к трубному материалу. Это...Метод также является наиболее распространенным методом производства медных материалов. Он не только используется в течение длительного времени, но и имеет зрелую технологию производства медных труб посредством реакции окисления. Этот метод производства является основным методом производства медных труб в Китае.

The price of tube billets was adjusted and lowered mainly due to the production restriction of environmental protection and the weak demand for temperature and weather. Recently, the terminal demand has also shrunk due to the sudden drop in temperature, causing a weak shock. According to the communication with local traders in Cangzhou, various good news last week led to the shipment of thermal expansion pipes in Cangzhou in the past two weeks, which is better in the off - season, and the shipment of some specifications has improved. However, the trading atmosphere in the small and medium - sized pipe market is still cold, it is expected that the market price of Cangzhou seamless pipe will be stable and weak in the near future. цена ,If you want to avoid this kind of situation for a long time, not only is the copper surface serious, it can be cleaned under normal circumstances, but it is not a big problem to keep it in the air for one year or more after ultrasonic treatment and immersion treatment, so this effect is very good.The evaporated zinc is immediately turned in to zinc in the air forming white smoke, which brings great difficulties to the operation and affects the health of welders. Thererefore, in the places where decorative brass pipes are welded ventilation and other protective measures should be strengthened. The poor weldability of brass will cause problems such as pores, cracks, zinc evaporation and so on.Strong connection firmness of copper pipe: the connection between copper pipe and copper fittings is strong.Чиба,Четыре из пяти основных областей применения медных пластин, медных стержней и труб: медь используется в строительстве в качестве различных труб, труб и декоративных устройств.However, it is difficult to change this situation too much in the short term. It is expected that the domestic strip steel price will mainly rise in the short term. It is reported that in order to pursue profits, Tangshan Iron and Steel Group Co., Ltd. Is currently increasing the supply of hot coils. It does not rule out that more steel mills in the future are inclined to one end of the plate in pursuit of profits,Чиба1060 Алюминиевые полосы, or to lay hidden dangers for the decline. As far as tomorrow is concerned, the price may still maintain a narrow range of shock operation pattern.Некоторые сталелитейные заводы в Ляонине заинтересованы в покупке чугуна, но местные ресурсы напряжены, сталелитейные заводы; Высокие цены привели к неустойчивости спроса и предложения. Цзянсу, Шаньдун, Шаньси, Хэбэй, давление на запасы сталелитейных заводов увеличивается. По мере снижения цен на сырье котировки сталелитейных заводов продолжали снижаться. В настоящее время поддержка спроса и затрат слаба и не имеет положительного повышения. Краткосрочный рынок чугуна слаб, его трудно изменить.
