연동관의 생산 방법은 경동관과 기본적으로 같다. 즉 경동관에 비해 퇴화 공정을 증가시켰다.동관의 퇴화는 그들이 고온로에서 하소하여 동관의 원소의 배열을 바꾼다는 것을 의미한다.그러나 불이 꺼지면 구리 파이프가 부드러워져 더 쉽게 구부러집니다.이런 방식으로 생산된 동관을 소프트 동관이라고 한다.
On the other hand， in the steel plant， the lock price of the steel plant has been falling all the time， and the order receiving is poor. The capacity utilization rate of the steel plant is low， but the market is still in oversupply. The stock of the steel plant and the spot stock are both risirising， so the market price has fallen sharply. Subsequently， the futures market rebounded in a wave， and the spot price also increased with the increase. There was an instant of large volume of transactions. However， with the decline of black futures， the market transaction volume shrank significantly. In addition， the inventory pressure was high， traders shipped at low prices， and the spot price fell under pressure. Due to the strong drop resistance of medium and thick plates， the drop amplitude and rate are less than those of threads.

구리 표면을 다시 밝게 만들고 싶다면 구리 점 용액으로 광택을 낼 수 있다.그것은 구리 표면을 더 밝게 할 뿐만 아니라 구리 표면의 녹과 산화층을 빠르게 제거하고 구리 자체의 광택을 회복 할 수 있습니다.
베 사 니Three of the five major application fields of copper plate copper bar and copper tube: copper is used to manufacture， and gun parts in the national defense industry. Every million rounds of copper are produced， - tons of copper are needed.
The market opened today. Although the performance of Zitong Pai futures was modest the overall market has stopped. The market mentality has not changed much sincekend. The price is stable， but some specifications are subject to negotiation， and the negotiation range is about - yuan. The overall rhythm of the market is stable and cold. In the middle of winter， the overall market in Northeast China has entered the traditional off-season， and the overall market has ended with little improvement. All companies are selling goods. The inventory level in Shenyang is very low due to the inventory clearing， and all construction sites have been closed. In addition to the transportation pressure brought by the low temperature， the market was bleak.

동관의 전기 전도 생산은 이런 방법의 최신 방법이다.그것은 전도성을 가진 나노 결정 구리 재료의 생산이다.이 원재료는 매우 특수하기 때문에 나노기술을 이용하여 생산되는 구리 재료로 구리 이온은 전도성을 통해 분리될 수 있기 때문에 분리된 구리 이온으로 구리 파이프를 생산할 수 있다.이런 방법은 매우 복잡하고 첨단기술과 새로운 설비가 필요하기에 국외선진국만이 이런 생산방법을 사용할수 있다.

First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C， while the humidity should be normal. The room should be kept ventilated.
약속 하고 신용 을 지키다.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.
Save materials and total cost， stability and performance， and can save maintenance.

프로젝트 범위주로 발전기， 모선， 케이블， 스위치설비， 변압기 등 전기설비와 열교환기， 도관과 태양에네르기가열설비의 평판집열기 등 열전도설비를 제조하는데 사용된다.흔히 볼 수 있는 구리합금은 황동， 청동， 백동 세 종류로 나뉜다.순수한 동판은 자홍색 금속의 하나로， it is very strong， not easy to be corroded， and can adapt to various environments. It can be used normally at low and high temperatures， so copper pipes need to be selected many times in other places.The color change on the outer surface of the copper tube is difficult to control due to environmental factors. To prevent moisture absorption on the surface and core of the annealed brass tube， a constant temperature and humidity packaging room can be built. Packaging in the packaging room can avoid the color change on the outer surface of the copper tube. However， it is not easy to control the situation that occurs in the processing process. The cost of ensuring constant temperature and humidity in the whole workshop is too high. The following measures are taken to control the process materials: In the season of high temperature and humidity，도 나 우 강 신도 시12Cr1MoV 합금 강판， during the production and processing of copper tubes， the amount of oil coating on the surface of copper tubes can be increased to form an oil film on the surface of copper tubes， which can isolate water vapor and corrosive gases， and prevent the corrosion of the surface of copper tubes; The humidity in the air at night is high and the outer surface of the copper pipe is prone to corrosion and discoloration at night. Closing the doors and windows of the workshop at night can make the situation worse; After the coil surface is cleaned in the rewinding process， the coating amount of passivation agent on the copper tube surface is increased. After blanking in the rewinding process， 적동 막대 및 적동 파이프: 구리는 전기 및 전자 산업에서 가장 널리 사용되며 전체 소비량의 절반 이상을 차지합니다.다양한 케이블 및 전선， 모터 및 변압기， 계측기， 슬라이딩 베어링， 몰드， 열 교환기， 펌프 등을 제조하는 데 사용됩니다.
도 나 우 강 신도 시Overview of three production methods of copper tube Copper tube is a very important material for copper materials. There are many ways to complete the production of this copper tube. For copper pipes， the following three methods are generally used to produce materials. The copper tubes produced by these three methods are not only very good in performance， but also very convenient to operate. There are three production methods for copper tube， so what are the three production methods for copper tube?
On October ， according to the Economic and Information Commission oong Province， at the end of September ， Shandong Province had resolved the overcapacity of million tons of pig iron and million tons of crude steel， the Development and Reform Commission of Handan City released the Plan for Handan City to Eliminate Excess Iron and Steel Capacity. Statistics show that the iron making capacity of Handan in was million tons and the steel making capacity was million tons.
In the morning trading today， the price of domestic copper bar fell. According to the monitoring data of Lange Steels cloud business platform， the average price of * mm hot rolled strip in key cities in China is down yuan from yesterday. Futures prices fluctuated， and the prices of spot market manufacturers eased slightly today. According to the feedback， the market was mainlysee yesterday， which caused the overall transaction blocked， and the mainstream manufacturers prices fell today.
