Roof tiles cold rolling mill

Types of roof tiles cold rolling mills

Generally, a roof tiles cold rolling mill is a machine that reshapes metal by passing it through rollers at room temperature. This is part of the process of producing metal with greater strength and durability because, during rolling, the crystalline structure of the metal is refined. Depending on the type of cold rolling mill used, the final product may have a uniform thickness, a desired shape, and a shiny surface. Different types of cold rolling mills are used to manufacture different types of roof tiles.

Two common types of cold rolling mills are continuous mills and batch-type mills. Below is a brief explanation of both, along with some other specialized cold rolling mills:

• A continuous cold rolling mill, also known as a tandem cold rolling mill, consists of various stands of rollers that consecutively pass the metal through it. At each stage, the metal takes on a desired shape. The final shape after going through all the stands is the final product and is usually shipped directly to customers without having to go through any additional processing.
• Twin-roll casting coupled with strip rolling is a process that falls under batch cold rolling mills. Here, molten metal is cast to form slabs of metal. This newly formed metal is then sent to the cold rolling mill to achieve its final desired shape and dimensions.
• A reverse cold rolling mill is equipped with two rollers. These rollers do not have a fixed shape or dimension and are sometimes referred to as "flattens." The mill works by passing the metal between the two rollers, with either roller performing the action of reducing the thickness of the material. The direction of movement of the rollers is reversed as the material moves through the mill.
• A composite mill combines both cutting and rolling processes, where the material is cut to strips and rolled to achieve the desired thickness simultaneously.
• Plant integrated cold rolling mills directly connect to the production facilities. The newly produced metal does not require further processing to be sent to the cold rolling mill.
• Temper rolling in a cold rolling mill softens the steel, thus increasing its strength and reducing residual stress. This is done by passing the steel through the mill while applying oil as a lubricant.

Specialized cold rolling mills are designed for specific types of metals, such as aluminum, copper, or alloy steel. These also include mills that have been customized to meet particular customer requirements. Standard features found in a typical cold rolling mill that may be included in specialized cold rolling mills are hydraulic coil breaks, manual coil breaks, hydraulic tension stands, uncoilers, and air lifts.

Specifications and maintenance of Roof tiles cold rolling mills

• Steel strip width:

  The steel strip width can be rolled by the roof tile cold rolling mill. The typical width is 600mm-1250mm.

• Effective working length:

  The effective working length is the length used for rolling, which directly affects the rolling production efficiency and the quantity of rolled products. The effective working lengths of roof tiles cold rolling mills are usually 2.5m, 3m, and 4.5m.

• Hydraulic system:

  The main parts of the hydraulic system of a cold rolling mill are hydraulic pumps, cylinders, flow valves, pressure valves, etc., which control the movement of the equipment by providing and discharging hydraulic oil. The function of the hydraulic system is to provide the necessary pressure and power for equipment operation, which affects equipment's rolling power, torque, pressure, etc. The parameters of the hydraulic system include: operating pressure; normally, it is above 15MPa. Pump power; normally, it is above 5.5kw. The volume of hydraulic oil cylinders can be from 0.3m³ to 0.8m³.

• Reduction ratio:

  The reduction ratio of a roof tile cold rolling mill refers to the ratio of the thickness of the raw material before rolling to the thickness after rolling. The higher the reduction ratio, the greater the thickness reduction, which indicates that the equipment can process materials of more thickness.

  This basically means that, for example, a cold rolling mill with a reduction ratio of 10:1 could take an initial thickness of 10mm and reduce it to a final thickness of 1mm.

• Controlling System:

  The control system of a cold rolling mill includes hardware and software. Hardware consists of controllers, sensors, transmitters, etc., while software includes programs and algorithms. The functions of the control system are to monitor and control the operational status and parameters of the equipment, which can realize automation and intelligence. The control methods of cold rolling mills include centralized control, remote control, etc.

• Lubrication system maintenance:

  Pay attention to the well-lubricated cold rolling mill, that is, timely addition and replacement of lubricant, to ensure effective operation of equipment's lubrication system.

• Tools and accessories maintenance:

  Protect and maintain the cold rolling mill's tools and accessories, such as rolling plates and blades, to ensure their quality and working condition, which can be accomplished by regularly cleaning, lubricating, and inspecting them.

• Regular inspection and adjustment:

  Carry out periodic inspections and adjustments to critical components such as the transmission system and control system of the cold rolling mill, ensure proper functioning and coordination of each part, and adjust accordingly as per the equipment operation.

• Regular replacement of parts:

  Regularly replace the easily-worn parts of the cold rolling mill, such as bearings, seals, etc., to ensure the stability and reliability of equipment operation.
