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， 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.
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， 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.

The price of pig iron market rose by - yuan this week， and the transaction was fair. With the increase of coke price， the cost of ductile iron in Shanxi， Henan， Liaoning， Shandong and other regions has increased. In addition， with the gradual release of downstream demand， the inventory of iron plants is not large， and iron plants have successively raised their prices. There are few iron foundries in Shandong， Jiangsu， Hebei and Shanxi， and the inventory remains low. As the coke price rises and the cost increases， the price of iron foundries rises again.
와플Red copper inventory may end the trend of continuous decline. With the increase of production restriction of steel enterprises and the pressure of demand， the continuous decline of iron ore port inventory may end. In addition， according to the new statistics of * *， the available days of imported iron ore of steel mills are days， which is one day lower than that before the National Day， the iron ore inventory basically meets the production requirements. Considering the future production reduction and restriction， the steel mill is not willing to replenish the inventory.
It is mainly used to manufacture electrical devices such as generators， buses， cables， switchgear transformers， and thermal conductive devices such as flat plate collectors for heat exchangers， pipes， and solar heating equipment. Common copper alloys are divided into three categories: brass bronze and white copper. Pure copper plate is a purplish red metal， commonly known as "copper plate"， "red copper plate" or "red copper plate".
First of all， we should set up a warehouse. The temperature in the warehouse should be generally kept at - ° C， stability and performance， and can save maintenance.

Disadvantages: Due to loose tissue and high pressure resistance， the pipe is only used to produce small air conditioning copper rods.

The evaporated zinc is immediately turned into zinc in the air， forming white smoke，반 다 야 치45# 원강， which brings great difficulties to the operation and affects the health of welders. Therefore， 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.
Generally， oxygen aylene is used as the gas source and LPG welding tool is used for heating. The torch of the welding tool shall face the joint and then continuously heat the whole joint. This will avoid excessive local heating.
