Design of Cold Rolled and Cold Drawn Steel Pipe Workshop
Cold rolled and cold drawn steel pipe workshop is mainly used for the production of cold rolled and cold drawn seamless steel pipe, which is an economical and practical equipment for reducing energy consumption and increasing production capacity. In the process of designing and constructing this workshop, the installation position of each equipment and the effective layout of production line should be considered to optimize the production operation process.
1. Workshop Layout
The workshop layout should be compact and rational, so as to ensure the smooth operation of production process and facilitate the transportation and positioning of each equipment. Firstly, the workshop and equipment should be separated with walls to isolate the humidity and dust and also to prevent the noise generated during the operation. Secondly, the installation position of each equipment should be considered, such as the cast pipe unit, piercing mill, cold drawing unit and other related equipments, which should be properly arranged according to their functions. Thirdly, the production line should be arranged in a straight line to ensure the smooth material flow and reduce the labor force. Finally, it’s important to make kind arrangement for the energy supply lines and piping system to every equipment.
2. Production Line
The production line mainly consists of two parts: the cold rolled production line and the cold drawn production line. The processes used in the cold rolled production line include roughing, sizing, continuous rolling and sizing again. The processes in the cold drawn production line mainly include cold drawing, straightening and polishing. Generally, the steel pipe produced by this workshop should be solid, round and straight.
3. Process Design
In the process design of this workshop, the details of the process route should be noted. Firstly, the choice of process route should be made according to the shape of pipe and the size of its diameter. Secondly, it’s also necessary to consider the heating, cooling and lubrication methods of production line. Thirdly, the technological parameters should be installed in the production process to ensure the accuracy of product size and surface quality. Finally, the safety protection measures should be taken to guarantee the safety in operation.
4. Equipment Configuration
The quality of a product depends on the quality of the equipment used in the production process. It is necessary to choose the appropriate equipment to process the steel pipe. Different equipments contains different functions and features, such as the cast pipe unit which is used to produce hollow blank of steel pipe and the piercing mill which can produce wide-diameter seamless steel pipe. Besides, other complementary equipments are also need to be equipped in the workshop, such as the cutting machine, testing machine and electric furnace.
To sum up, the design of cold rolled and cold drawn steel pipe workshop requires careful consideration at every step. The workshop should be laid out compactly so as to ensure the smooth material flow and labor force. The detailed process route and technological parameters should be taken into consideration to ensure the accuracy of product size and surface quality. And proper equipments should also be correctly selected to guarantee the product quality. With all these factors taken into account, this workshop could operate efficienctly and safely.
