FOR SALE DANIELI ROD TRAIN LINE FROM 16 TO 5.5 MM ### Operating Principle of the Danieli Wire Rod Train The Danieli wire rod train (or rolling mill) is a type of rolling mill used for the production of wire rod, a form of hot rolled steel used in various industrial sectors. Danieli is a renowned brand in the rolling industry and their systems are designed to offer high precision and productivity. **1. **Composition and Structure:** - **Rolling Rollers:** The heart of the wire rod train is made up of a series of rolling rollers arranged in sequence. These rollers have specific shapes and configurations to progressively reduce the thickness of the material and obtain the desired shape. - **Feeding and Input:** The raw material, generally in the form of steel billets, is introduced into the rolling mill via a feeding system. The material passes through the rollers and is gradually reduced and formed. - **Control and Automation:** Modern rolling mills, like those of Danieli, are equipped with automated control systems that regulate roller speed, pressure and other operating parameters to ensure the quality and consistency of the finished product. - **Cooling System:** Some rolling mills include a cooling system to manage the temperature of the material during the rolling process and improve product quality. **2. **Operating Principle:** - **Heating:** Steel billets are heated to high temperatures before entering the rolling mill to make the material more malleable and facilitate the rolling process. - **Lamination:** The hot material is passed through a series of rollers which compress and shape it progressively. Each pass between the rollers further reduces the thickness and changes the shape of the material. - **Dimension Control:** During the process, the material is monitored to ensure that dimensions and specifications are met. Control systems regulate parameters to maintain the quality of the final product. - **Cooling and Exit:** After rolling, the material can be cooled and then cut or further processed depending on the specifications required. ### How to Use 1. **Preparation:** - **System Check:** Check the rolling mill to ensure that all parts are in good condition and that the control system is working properly. - **Material Loading:** Loads steel billets into the mill feed system. Make sure the material conforms to the specifications of the lamination process. 2. **Operation:** - **Process Startup:** Start the rolling mill and adjust the operating parameters such as roller speed and pressure. Monitor the process to ensure the material is laminated correctly. - **Quality Control:** During the rolling process, regularly check the dimensions and quality of the material to ensure it meets the required specifications. 3. **Maintenance:** - **Cleaning and Inspection:** Keep the mill clean and regularly inspect rollers and components for signs of wear or damage. - **Lubrication:** Follow the manufacturer's recommendations for lubrication of moving components to ensure smooth operation. - **Repairs:** Make timely repairs to maintain the efficiency of the mill and prevent more serious problems. ### When It Is Best to Buy a Used Wire Rod Mill 1. **High Production Volume:** If your company has a high production of wire rod and needs a rolling mill, purchasing a used one can be an economical solution to meet demand without invest in a new plant. 2. **Limited Budget:** If your budget for new equipment is limited, a used rolling mill may offer a more economical solution.
