Barter is the present and the future of international trade, especially for people who is starting in the import export business. Barter and more: Triangular operations.
As an important part of coal mine conveying , scraper conveyer directly affects the safety and economic benefit of coal production. In order to promote the safety of coal mine production and increase the production efficiency of coal mine, the forging scraper conveyer scraper is widely used in every big coal mine. Next Henan double annals introduces the forging technology of scraper for you.
In the working process of the scraper conveyor, the scraper and chute, groove side and other parts will contact, produce certain friction, causing wear. In addition, coal and gangue will also have a certain impact on the scraper, affecting the life cycle of the scraper. This working condition brings wear and tear, impact is inevitable, so in the production of scraper to choose wear - resistant materials. After comprehensive consideration of hardness and chemical elements, the forging scraper produced by Henan Shuangzhi adopts materials such as 27SiMn, 40Cr and 40Mn2.
Chemical composition, properties and dimensions of the material are examined after it is entered into the plant, and then the blank is heated in a reheating furnace with a sawing machine. After heating, it is forged with a forging hammer, then punched and cut with a press machine. After forming the scraper workpiece, waste heat quenching and tempering treatment, improve the strength and toughness of the scraper conveyer. Then the finished scraper forgings will be tested, and then shot blasting and surface treatment. Finally, it is dipped in paint.
Henan Shuangzhi production of various types of scraper conveyor scraper, hardness and strength are relatively high, wear resistance is strong. If you need the scraper conveyer, you are welcome to contact us in time.
