1. History of Thermal Spraying China's thermal spraying technology began in the 1950s, when Wu Jianchun and others in Shanghai set up the first domestic specialised spraying plant, the development of oxyacetylene flame wire spraying and electrospray device, and foreign metal spraying business. In the 1960s, a few military units began to study plasma spraying technology (such as the Beijing Institute of Aeronautical Technology, Aerospace Corporation Rocket Technology Research Institute 703, aviation sector 410, 420, 430 plants and other units), began to be applied in China's military sector. To the mid to late 70s appeared many varieties of oxyacetylene flame metal powder spraying (fusion) equipment and a variety of nickel, iron, cobalt-based self-melting alloy powder and composite powder coating materials, to the rapid forward development of thermal spraying technology has laid a solid foundation. Thermal spraying materials are thermal spraying technology, "cooking food", the increase in the variety of materials and performance improvement will directly improve the quality

1. Analysis of reasons for roller breakage 1.1 During the stacking of steel in the precision rolling unit, the heat of the rolled piece is transferred to the adjacent roller rings, causing the temperature of the roller rings to rise and the thermal stress to be concentrated. However, during the accident handling process, the surface temperature of the roller rings rapidly decreases, making it easy for the phenomenon of roller breakage to occur. The main reasons for stacking steel inside the unit are as follows: (1) Improper roller matching. The Morgan high-speed wire rod precision rolling unit adopts collective transmission, and the transmission speed ratio of each frame is different. Therefore, it is required that the precision rolling machine not only meets the gear transmission ratio between each frame, but also requires the outer diameter error of the roll ring of the same frame to be controlled within ± 0.05mm when matching rollers. Otherwise, the rolled piece will shake between the two frames, ultimately causing steel stacking between the frames. (2) Poor alignment of the rolling line. There are various guide grooves such as air seals, water tanks, recovery sections, and pinch rolls in the guide rails between each frame in the precision rolling unit, as well as the section from the unit outlet to the wire drawing machine. If the rolled piece is obstructed during high-speed operation, it can lead to the phenomenon of steel stacking. (3) The guide rail of the precision rolling unit is faulty. Insufficient oil and gas lubrication or cooling of the guide bearings in the precision rolling unit can lead to bearing damage, inflexible rotation of the guide rollers, jamming, and cracking, resulting in the phenomenon of steel stacking. (4) Raw material defects. There are defects in t

Abstract: Petroleum drilling tools occupy a considerable cost in petroleum drilling engineering. The working environment of drilling tools in the underground is very harsh, not only subjected to composite alternating stresses such as tension, pressure, and torsion, but also subjected to erosion and corrosion of drilling fluid. After using drilling tools for a period of time, they will produce surface wear, internal cracks, etc., resulting in the scrapping of drilling tools. Therefore, rebuilding and repairing damaged drilling tools and putting them back into use have significant economic and social benefits. This article introduces the remanufacturing and repair technology of drilling tools, including identification of drilling tool damage, classification of levels, reconstruction and repair, and inspection and evaluation. 1. Damage situation and corresponding treatment of drilling tools The reconstruction and repair technology of drilling tools is aimed at different parts and damage results of drilling tools. Fuzzy support vector machine theory is used to identify drilling tool damage and classify damage levels. Based on the classification results, drilling tools with macroscopic and microscopic damage are reconstructed

This year's Double Eleven is a bit cold, but the steel industry is hot. With the upcoming meeting between China and the US dollar, as well as the continuous stimulation of favorable policies, the steel industry seems to be in a frenzy in the near future. On the night of November 14th, the threaded steel reached a high of 3962 yuan/ton, and the industry cheered and cheered on the social media. However, industry insiders remind that steel prices are constantly rising, but the steel market is facing a dilemma of having prices but not a market, with demand still insufficient and shipments still very bleak. The current industry is in a frenzy, and the only factors affecting steel prices are political factors. Moreover, steel prices have been continuously rising, but they are like mirages and castles in the air, wary of the risk of decline. Since late October, the black sector has sounded the "clarion call" of price counterattack in the off-season under the stimulus of multiple macro positive expectations, such as the statement of the central finance announcing the issuance of an additional 1 trillion yuan of special treasury bond. Recently, the prices of black bulk products such as coal, coke, and steel have increased significantly. The prices of coking coal, iron ore, raw fuels, and threaded and hot-rolled steel have all exceeded the peak prices of the 1990s season. The spot prices of coke have also broken expectations for multiple rounds of price hikes and rapidly increased. From October 24th to the 11th of this month, the main contract prices of coking coal futures increased by more than 20%, and the main contract prices of coke and iron ore futures also increased by more than 15%. According to data from Bu

Since 2022, the steel market has taken a sharp turn for the worse, and with the decline in the global economic situation, the steel industry has also been greatly impacted. Steel companies are under enormous pressure. Steel prices plummeted, raw material costs rose, steel companies profit a large area of decline loss steel prices from the highest price of 4,880 yuan per ton in 2022, plummeted to the lowest of 3,300 yuan per ton in 2023, a plunge of 1,580 yuan per ton; Many iron and steel enterprises are operating in difficulties, forced to lay off employees to save themselves, and the number of workers in the steel industry has plummeted by more than 120,000 people in 13 months! Weak market demand at home and abroad, serious excess steel production capacity, and high production and operating costs are called the "three mountains" that are currently under pressure from steel companies in the industry. The "three mountains" have pushed the steel industry to the edge of a cliff. The main factors affecting steel consumption are housing construction, infrastructure and machinery manufacturing, of which housing construction accounts for nearly half. Since last year, due to the continuous adjustment of real estate investment, construction and sales market, the sales and profits of upstream steel enterprises have been greatly affected. Excess production is excess on the high point, lack of demand is also insufficient at the low point of the economy, the huge contrast caused by the decline in steel prices, so that many steel companies can not afford. According to statistics, as of the first half of 2023, the total assets of the 50 listed steel enterprises were 2375.885 billion yuan, the total liabilities were 1328.837 billion yuan, and the average asset-liability ratio was 49.12%, with an average year-on-year increase of 1.09%. Among them, there are 8 steel enterprises asset-liability ratio between 60% and 70%, respectively, Liusteel, Citic Special Steel, general spec

Steelmakers talk about how to improve the profits of steel mills. The general direction is to reduce consumption, improve quality, shorten rhythm, ensure that one furnace is a furnace, and avoid waste is the bottom line. Specifically speaking, there are the following points: 1. Strictly control the loading amount, such as the tare, gross weight and net weight of scrap and molten iron loaded on site, must be known. The proportion of scrap steel structure shall be loaded in accordance with the prescribed proportion. Easy to operate stably and accurately. 2. Improve your life. The temperature is controlled well, the end carbon is lifted, and the cost of the alloy deoxidation operation is reduced. 3. Steel must be out of the net, there can be no leftover steel. 4. The alloy ratio is narrow. 5. Control calcium consumption. 6. Ensure that production goes straight, and the interruption of production is the biggest and most direct waste of cost reduction. Put an end to the revision of steel grades. Correction is to sell high-priced steel into low-priced steel. 7. Recycle scrap steel. Bale edge, billet head, wool iron in slag field, and intermediate bale block must be recovered and digested during shift. 8. Put an end to the small waste around you, although it is small, accumulate more, it will be big. In the wor

Industry leaders have long tasked their development and research teams to create coatings that are wear resistant. Numerous industries benefit from coatings that can tolerate an environment that is corrosive, such as that offered by solvent-based inks, chemicals, and even water under the right circumstances. Additionally, when surfaces roll together or rub against each other, abrasive wear occurs, as well. The chromium oxide coatings used today create ceramic, hard surfaces which stand up better to any number of threats. The process of applying chromium oxide coatings using a plasma torch involves injecting powdered coating material into the torch. Through an arc, this powder passes while a plasma flame produces heat. The coating material is melted by this heat which allows it to better adhere to the desired soon-to-be-coated parts.
