Why do cast iron platforms need to be scraped and scraped

Cast iron platform; The scraping process of cast iron is complicated, and its scraping quality directly affects the flatness, accuracy, etc. of the table. It is one of the important links in the production process of cast iron and also a process of precision and flatness. The tool used for scraping is a scraper, which has a diverse range of shapes, dimensions, and the quality of the blade.

Cast iron; The scraping process is chaotic, and its scraping quality directly affects the flatness, accuracy, etc. of the table. It is one of the important links in the production process of cast iron and also a process of precision and flatness.

The tool used for scraping is a scraper, which has a diverse range of shapes, dimensions, and the quality of the blade. The choice of tool directly affects the scraping power and the fatigue intensity of the scraping personnel. During the scraping process, timely grinding of the scraper to reach a sharp and flat edge is necessary to evenly scrape the tabletop, thereby increasing the power of the scraping operation. For small-scale cast iron production, it is recommended to use a single person operation method as much as possible. Large scale pathways require multiple people to work together, and multiple people should try to maintain the same scraping force. The density should be as common as possible. Before the scraping operation, the semi-finished cast iron products should be horizontally adjusted, and the scraping operation can only be carried out after the adjustment is correct. If scraping is carried out on a path that has been adjusted horizontally, even if the scraping points are even, their flatness is invalid. 3. The parallel scraping method is not advisable, and the 45 degree angle scraping method is commonly used. The scraping direction should be vertically inserted twice in a row, and the scraping points should not be repeated. 4. When coloring, it is necessary to mix the coloring material (red lead powder) to create vivid colors, making it easy to identify contact points. Secondly, it should not be too thick or washed, as it may affect visual recognition and make dragging and grinding operations difficult. 7. Regarding the mutual research of the three pathways, print the corresponding number on each cast iron pathway. Adopting the method of mutual research based on serial numbers. We should conduct mutual research according to the rules and not change the order of mutual research during the process. 5. After each single-sided scraping, use a fine oilstone to lightly polish the tabletop. During scraping, the burrs may prick the scraping personnel and cause scratches on the cast iron passing through the tabletop due to the distance of the next use. During the scraping operation, it is not allowed to repeatedly drop the scraper onto the same scraping point as the position of the scraping point can be clearly seen with the naked eye. Scraping should be done in a unidirectional cycle and cannot be done in a regional manner. After scraping the entire surface, use a brush to clean up the scraped iron filings, visually identify the areas that were not scraped, and apply the same force to repair the blade. Only in this way can one reach the standard of contact for scraping and grinding points. During the scraping operation, attention should be paid to changes in room temperature, which can affect cast iron; There is a significant connection between the passage table and the cast iron. An increase in temperature will cause the center of the passage to become concave, while a low temperature will cause the table to become convex. Timely observation of temperature changes is crucial to avoid table changes caused by temperature changes, which can lead to discrimination errors and waste of working hours for scraping personnel. 8. The handle of the scraper should be installed firmly, and relevant auxiliary materials that can enhance the grip force between the hand and the scraper should be wrapped around it in the corresponding gripping position. 9. The placement height of the cast iron pathway is stable and sturdy, and the height is suitable for scraping personnel. If it is too high or too low, it will cause the operators to easily fatigue, and the quality and power of the operation will be greatly reduced. 10. During the scraping and grinding operation, attention should be paid to the dragging and lifting of the grinding tool. When scraping, dragging, and lifting, personnel should pay attention to the high concentration of force. When scraping on a table with T-shaped grooves or circular holes, attention should be paid to avoid personal injury to the operator due to the head space of the blade. During scraping operations, due to high concentration of energy, one should not be distracted by idle chatter. The above 10 points are the fundamental precautions for scraping and grinding. During the scraping process, the above specifications should be followed for operation. Only in this way can we complete the scraping operation of the cast iron pathway with high quality and quantity.
