Marble pattern steel, also known as marbled steel, refers to a type of steel that has a distinct pattern resembling the natural veins and swirls found in marble stone. This effect is achieved through various metalworking techniques, such as pattern welding, acid etching, and surface manipulation. Below are some common techniques used to create marble pattern steel: ppgi marble coils,prepainted marble steel,steel marble sheet,prepainted marble coated galvanized ppgi Wuxi Shengshu Metal Co., Ltd. , https://www.wuxissmetal.com
According to the local agricultural machinery management department, the total power of agricultural machinery in Ningxia reached 6.1 million kilowatts last year, the number of agricultural tractors was over 180,000, and the number of agricultural machinery reached 200,000. The matching ratio reached 1:1.1; the main crops in the region were cultivated and harvested. The comprehensive mechanization rate reached 43%, 2% higher than the national average.
Ningxia is located in the northwestern ethnic areas. Twenty years ago, there were less than 70,000 agricultural machines of various types, and the total power was only 1.5 million kilowatts. The traditional “two-cattle bar†and horse-pull donkey pull were quite common. Since the 1990s, especially in recent years, national and local governments have implemented subsidies for agricultural machinery purchases, which has led to an exponential increase in the number of agricultural machinery in Ningxia and a rapid increase in the level of agricultural mechanization.
This year, Ningxia has implemented subsidies for purchasing farm machinery for 42 million yuan. The subsidies cover all cities and counties in the region. At the same time, 20 agricultural mechanization demonstration parks have been built, and the promotion of agricultural machinery and other weak links in agricultural facilities has been intensified. It is expected that the total power of agricultural machinery will be increased. To reach 6.4 million kilowatts, the comprehensive mechanization rate of the main crops will be raised to 45%.
1. **Pattern Welding**: This technique involves layering and forge welding multiple sheets of steel together. The layers are then folded, twisted, and hammered repeatedly to create intricate patterns. The final product is a strong yet visually appealing steel with a marbled appearance.
2. **Acid Etching**: Acid etching is a process in which a chemical solution is applied to the steel's surface to selectively remove material and create a pattern. The steel is typically coated with a protective layer, such as wax or masking tape, and the desired pattern is then drawn or marked onto the surface. The acid solution is applied and reacts with the exposed metal, creating the marbled pattern as it dissolves the steel in a controlled manner.
3. **Surface Manipulation**: In this technique, the steel's surface is physically altered to create the appearance of a marbled pattern. This can be achieved through methods such as engraving, hammering, or grinding. Once the desired pattern is created, the steel can be further enhanced by applying patina or other surface treatments to accentuate the pattern's appearance.
Marble pattern steel is often used for decorative purposes, such as in the creation of custom knives, swords, and other metalwork items. It is also popular in the field of architecture and interior design, where it can be used as a unique and eye-catching material for various applications.
Farmland above 50% in Ningxia to improve the level of mechanical machinery
Xinhuanet Ningxia Channel, June 24th (Reporter Jiang Xuecheng) Ningxia was once one of the most backward provinces in agricultural cultivation in China. Today, the area of ​​farmland cultivated by the Hui Autonomous Region has accounted for 52% of the total cultivated land, which has significantly reduced the size of developed areas. gap.
