On October 27th, the coal "three brothers" collectively lowered their limit. Among them, the main contract of coking coal and coke futures fell by 8.99% at the opening, and the price of the main 2201 contract of thermal coal futures fell below 1,200 yuan/ton, a decrease of 10%. One month low. Ruan Xinan, an analyst at Yongan Futures, told the Futures Daily reporter that before coal prices fell, the upward momentum was mainly due to the shortage of supply and the unexpected increase in demand. The continuous destocking of thermal coal contributed to the upward price increase. In the second half of the year, as the country continuously introduced relevant policies and measures to ensure the supply of thermal coal and stabilize coal prices, the output of thermal coal production areas was gradually released. At the same time, downstream demand was seasonally declining, and under the pattern of supply increase and demand decrease, thermal coal inventory began Accumulation quickly,...

According to different conditions, the metal material is heated to a suitable temperature and kept warm, and then cooled in different ways to change the metallographic structure of the metal material and obtain the required structural properties. This process is usually called metal material heat treatment. What three processes are included in the heat treatment of carbon steel tubes? Heat treatment of metal materials is divided into overall heat treatment, surface heat treatment and chemical heat treatment. The heat treatment of carbon seamless steel tubes generally adopts the overall heat treatment. Steel pipes need to go through basic processes such as heating, heat preservation and cooling during heat treatment. In these processes, steel pipes may have quality defects. The heat treatment defects of steel pipes mainly include unqualified structure and performance of steel pipes, unqualified dimensions, surface cracks, scratches, severe oxidation, decarburization, overheating or over...

"From 18:00 on the 29th to 18:00 on the 30th, 92 trains departed from Hudong Station (the first-class station on the Daqin Line), with a completed transportation volume of 1.3 million tons." After the end, the transportation volume rapidly increased to 1.3 million tons. According to the data of China Railway Taiyuan Bureau Group Co., Ltd. (hereinafter referred to as "China Railway Taiyuan Bureau"), the company plans to load 16,000 vehicles per day from October 1st to 10th for the task of ensuring electricity and coal supply, and actually completed 18,901 vehicles, with an additional 2901. Cars: From October 11th to 31st, 19,500 cars will be installed on the scheduled day of the task of ensuring the supply of electricity and coal, 20,226 cars have been actually completed, and an additional 726 cars will be installed. Jinneng Holdings Coal Industry Group provides the loading data of foreign transportation shows that on October 28, the group plans to load 7,500 vehicle...

 There are two types of galvanized seamless steel pipes, hot-dip galvanizing (hot-dip galvanizing) and cold-dip galvanizing (electro-galvanizing). Hot-dip galvanizing has a thick galvanized layer, which has the advantages of uniform coating, strong adhesion, and long service life. However, the cost of electro-galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipes. How to check the quality of galvanized seamless steel pipe? According to the requirements of the standard, the galvanized pipe manufacturer pointed out that the inspection content of the geometric dimensions of the galvanized seamless pipe mainly includes the wall thickness, outer diameter, length, curvature, ovality and end shape of the galvanized seamless pipe. 1. Wall thickness inspection The tool used for wall thickness inspection is mainly a micrometer. When checking, measure the wall thickness of the galvanized pipe one by one with a micro...

Since November 4th, my country has experienced strong cooling and cold wave weather from north to south, and severe weather such as strong winds and blizzards in some areas has a certain impact on coal production. On November 6, national coal production fell below 11 million tons, and daily output fell. More than 1 million tons. The National Development and Reform Commission urged major coal producing areas such as Shanxi, Shaanxi, and Mongolia to organize production scientifically and rationally, strengthen safety management, speed up the resumption of production, and minimize the impact of cold waves on stable production and increased production. At present, the cold wave in major coal-producing provinces has basically ended, and national coal production has rebounded rapidly. The dispatched average daily output from November 7th to 9th reached 11.75 million tons, which has exceeded the average production level of the days before the cold wave. The output on November 9 reached 1182.5...

The arrival of the peak season for thermal coal demand has improved the market’s pessimistic expectations to a certain extent. However, with the in-depth work of ensuring supply and price stabilization, domestic coal supply capacity has increased significantly, and short-term thermal coal prices will continue to be under pressure. Domestic demand is expected to increase Under the influence of strong cold air, the temperature in most areas of my country has dropped significantly. As the frost line advances to the south, as the temperature drops, the consumption of electricity and coal will gradually increase due to the rising demand for electricity by residents, entering the peak season of traditional demand. According to the analysis of thermal coal consumption in previous years, the peak season usually lasts 1-2 weeks before the Spring Festival. What is the specific increase in demand for thermal coal during the peak season? We use September data as an anchor point and calculate based...

In early October, iron ore prices experienced a short-term rebound, mainly due to the expected improvement in demand margins and the stimulus of rising ocean freight prices. However, as steel mills strengthened their production restrictions and at the same time, ocean freight rates fell sharply. The price hit a new low during the year. In terms of absolute prices, the price of iron ore this year has fallen by more than 50% from the high point, and the price has already fallen. However, from the perspective of supply and demand fundamentals, the current port inventory has reached the highest level in the same period in the past four years. As the port continues to accumulate , This year's weak iron ore prices will be difficult to change. There is still an increase in mainstream mine shipments In October, the iron ore shipments in Australia and Brazil decreased year-on-year and month-on-month. On the one hand, it was due to mine maintenance. On the other hand, the high sea freight ha...
