Pakistan Coal Power Plant Water Supply Project

 Xinyue Steel Group welcomed two Pakistan Clients this week. Their company is constructing two coal-fired power plants and plan to lay two pipelines for water supply. The main purpose of this visit is to come to our factory to inspect the production equipment, production capacity and steel pipe quality, so as to ensure the Purchasing quality and construction progress of the project. First of all, we arranged a meeting and had detailed business talks with customers. During this meeting, the clients raised questions and asked about the production capacity of the ordered steel pipe, the internal and external coating requirements and how to ensure the outer diameter of the pipe end during transportation. In response to the technical difficulties and quality questions raised by clients, our production manager yang, marketing manager Aissa and salesman tony gave clear answers to clients. After meeting, we led Pakistani clients to visit the production line of the factory. Clients mainly i...

Application of Seamless Steel Tube in the Field of Solar Energy

 The application field of seamless steel pipe has been expanded little by little, and its various characteristics have been brought into full play in various fields. Now it has also been applied in the field of solar power generation and manufacturing. However, because of the different assets and technical capabilities of manufacturers, the requirements for seamless steel pipes are also uneven. At this stage, there are three key types of behavioral commodities in the electric water heater sales market, namely natural gas water heaters, domestic water heaters, and solar power electric water heaters. The solar power electric water heater is generally composed of a hot plate, a thermally insulated water storage tank, a connecting pipeline, a support frame and an automatic control system. Among them, the vacuum solenoid valve, water storage tank and other accessories are all rectangular seamless steel pipes. However, each processing technology is different, and the requirements for sea...

Welcome Saudi Arabia Client Visit Our Company

 At the beginning of April, customers from Saudi Arabia and our company began to negotiate orders for steel pipe welding flanges. On the afternoon of May 14, after a month of conversation, the customer decided to come to our company for face-to-face communication, determine the order details and audit the factory. During the meeting, we told the guests about the background of our company, the factory situation, and introduced the steel pipes and foreign projects that we exported over the years. The guests were very satisfied with our warm hospitality and were very happy to receive the most sincere recognition from the guests. During the inspection process, the customer gave us a favorable review of our pipes, and we professionally touched the customers. The customer stated that they will quickly decide the purchase demand after returning to China, and hope that we can give the best price. As long as we do our best to provide our services, and always adhere to the "integrity-based,...

Why did India return to the ranks of net steel importers?

 Although India has repeatedly raised its domestic steel production capacity target, it has recently encountered a bit of "frustration" on the road to realizing the dream of a big steel country. According to the latest data released by India, in the fiscal year of 2019 (April 1, 2018 to March 31, 2019), India's finished steel exports amounted to 6.36 million tons, down 34% year-on-year. In the same period, imports of finished steel products increased by 4.7% to 7.84 million tons. Exports failed to “outperform” imports, and after three years, India once again became a net importer of steel. For India, which is trying hard to develop the local steel industry and wants to increase the self-sufficiency rate of steel, this set of data will bring more or less frustration. “Identity Conversion” is a multi-factor superposition and multi-party game outcome In recent years, in order to get rid of the hat of the net importer of steel, the Indian government and local steel companies ...

High frequency pipe welding consumables selection standard

 Selection criteria for high frequency welded pipe (ERW) welding consumables Classification of welding rods: (1) Classification by slag properties Welding electrodes can be divided into two categories: acid electrodes and alkaline electrodes. The electrode whose slag is mainly acid oxide is called acid electrode. The electrode whose slag is mainly alkaline oxide and calcium fluoride is called alkaline electrode. Among carbon steel electrodes and low-alloy steel electrodes, low-hydrogen electrodes (including low-hydrogen sodium, low-hydrogen potassium, and iron powder low-hydrogen electrodes) are basic electrodes; electrodes of other coating types are acid electrodes. (2) Classification by electrode usage Can be divided into: structural steel electrodes, molybdenum and chromium molybdenum heat-resistant steel electrodes, stainless steel electrodes, surfacing electrodes, low temperature steel electrodes, cast iron electrodes, nickel and nickel alloy electrodes, copper and copper allo...

Why do steels with high carbon content break easily?

 Bars with high carbon content have undergone many breaks, such as the shaft made of 45# steel, which breaks after a short period of time. Sampling from the parts after the fracture and performing metallographic analysis often fails to find the cause, that is, it is not a practical reason to find some reasons. In order to ensure higher strength, it is also necessary to add carbon to the steel, which in turn precipitates iron carbides. From an electrochemical point of view, iron carbide acts as a cathode, accelerating the anodic dissolution reaction around the substrate. The increase in the volume fraction of iron carbides within the microstructure is also attributed to the low hydrogen overvoltage characteristics of the carbides. The surface of the steel is prone to generate and adsorb hydrogen. While the hydrogen atoms penetrate into the steel, the volume fraction of hydrogen may increase, and the hydrogen embrittlement resistance of the material is significantly reduced. The sign...

Cause Analysis of Splashing in Converter Steel making

 Common splashes in converters are mainly divided into explosive splashes, foam splashes and metal splashes. 1 Causes of explosive splashing The carbon-oxygen reaction in the molten pool develops unevenly, and a large amount of CO gas is instantaneously generated, which is the root cause of explosive splashing. Carbon-oxygen reaction: [C]+(FeO)={CO}+[Fe] is an endothermic reaction, and the reaction rate is affected by the carbon content of the molten pool, the content of slag (TFe) and the temperature. Due to operational reasons, the molten pool is suddenly cooled, suppressing the intense carbon-oxygen reaction; the oxygen produced by the human being generates a large amount (FeO) and accumulates; when the temperature of the molten pool rises again to a certain extent (generally at 1470 ° C) Above), when (FeO) accumulates to more than 20%, the carbon-oxygen reaction proceeds again at a more violent speed, and a large amount of CO gas with a large amount of energy is instantaneously...

Preventive Measures of Splashing in Converter Steel making

 1 correct gun position control To some extent, the oxygen lance operation of the double-blown converter steel making is mainly to adjust and control the proper (FeO) content in the slag through the change of the gun position to meet the needs of each stage of the blowing process. If the (FeO) is improperly controlled, it will bring difficulties to the blowing, such as the slag is too late, easy to "back to dry"; or the slag is too early, easy to splash, so the key to controlling the splash is to control the blowing position . 1.1 Adjustment and control of the gun position in the pre-blowing stage Before opening the blow, the operator should know the following details: a) the composition of molten iron, mainly the content of silicon, sulfur and phosphorus; b) molten iron temperature; c) The condition of the furnace is whether it is a new furnace or an old furnace, whether it is replenished, what is the amount of the furnace, whether there is any residual molten steel and slag...
