The production of large-scale asymmetrical bloom is an important step in the steelmaking and rolling industry. Because of its peculiar shape, the production of large-scale asymmetrical bloom requires high levels of process control and experience. The most important factor affecting the production quality of large-scale asymmetrical bloom is the operating procedure.
In the production of large-scale asymmetrical bloom, the control of the temperature and energy input is an important factor to ensure the quality of the product. Before entering the furnace, the temperature of the steel must be stabilized. Generally speaking, the temperature should be controlled between 1100-1200 degrees, and the total energy must be strictly controlled. After the steel enters the furnace, the temperature should be adjusted and maintained according to the situation.
According to the size and shape of the large-scale asymmetrical blooms, the speed of the rolling must also be precisely controlled. This requires the production personnel to not only have their own operating experience, but also master the operation process of the rolling machine. The higher the speed of the rolling machine, the higher the quality of the product. In addition, the formation of large-scale asymmetrical blooms must pay attention to the furnace atmosphere. Open hearth furnace and controlled atmosphere furnace both are suitable for the production of large-scale asymmetrical bloom. For open hearth furnaces, bearing oil, oxygen and chlorine gas should be added. Oxygen and chlorine gas can reduce the occurrence of oxide scaling and carbon brittle metamorphism.
In the production process of large-scale asymmetrical bloom, its deformation degree should also be tightly controlled. It is the most important parameter in the direct rolling process. In addition, the production of large-scale asymmetrical bloom should also pay attention to the temperature of the roll surface. The roll surface temperature of controllable roll and roll mill should be controlled in a certain range. Otherwise, it is easy to cause the roll surface to be heated, which will affect the quality of the products.
In summary, the accurate control of process parameters is the key to ensure the quality of large-scale asymmetrical bloom production. This requires the production personnel to have the experience of accurately controlling the process parameters and parameters in the production process. At the same time, the continuous transformation and improvement of production equipment is also necessary for the production of large-scale asymmetrical bloom. Only by keeping up with the times, paying attention to new technology and equipment, can the efficient and safe production of large-scale asymmetrical bloom be ensured.
