Causes and control of strip rolling In the process of plastic deformation, the strip steel has different degrees of damage to the strip due to excessive local pressure, and the abnormal accident that causes the perforation of the strip to be damaged is called rolling through. Rolling through not only severely restricts the stability of…
Difficulties in rolling of thin gauge hot rolled products and countermeasures Taking the thin gauge container plate SPA-H (thickness ≤2.0mm) as an example, the rolling characteristics are introduced: (1) The thickness of the container board with thickness ≤ 2.0mm has an order, but the order of the intermediate transition specification (between 2.9 and 2.0mm) is…
The rolling process is the most common industrial process, which is used for making large length cross section like sheets and plates of steel and aluminum for structures. Rolling mills are used for completing the rolling process. These are available with various steel roll manufacturers in a variety of shapes and sizes as per requirement of the…
Rolling is a process that is followed in most metal making activities. Material is passed through a stock of rollers in order to maintain a level shape and thickness. Generally, there are two types of rolling, i.e., hot rolling and cold rolling. No matter what type of rolling, a mills roll makes the metal crafting…
The steel industry is vast and it is seldom easy to find a company that contributes to every market need with perfection. Some of them are not able to maintain quality in their supply and some of them fail to provide the required supply on time. There are such steel products that can be only…
Modern Steelmaking Technology Introduction： The requirements on steel products have increased steadily. These requirements include higher strength in order to reduce the weight of a construction, better toughness to allow for its safe application particularly at subzero temperatures, better cold formability and surface quality especially for the automotive industry and better weld ability allowing for…
The pressure water film copper mould tube is as follows: four steel plates are fixed at the lower end of the copper mould tube , water is sprayed from the slits processed on each steel plate, and the steel plate is placed in line with the copper mould tube surface, and left between the surface…
The curved copepr mould tube is developed from the perspective of heat transfer, based on the air gap, and is analyzed by thermal deformation of the mold and shrinkage of the billet. The basic features are as follows: The copper mould tube consists of three parts viewed from the axial direction. The upper part has…
Requirements for copper mould tube performance: Good thermal conductivity, condensation of liquid metal in the crystallizer, copper plate, copper tube work, the surface of the inner cavity is heated in the gradual condensation state of the liquid metal, and the back is heat transfer in the circulation of the cooling water. Achieve heat transfer, about 5%-20%…
What are the causes of cracking of nickel alloy coating? The causes of cracks in the coating are: (1) cracks due to internal defects of the base metal of the copper plate expand outward, causing cracks in the plating layer. (2) Due to the metallographic structure of the alloy plating layer, impurities exist in the…
