As China is a country with water resource shortage, more than 600 water-deficient cities and more than 200 serious water-deficient cities, the water supply and saving industry is in the spotlight, and the nodular cast iron pipe has wide development prospect.
With the wide-range use of the nodular cast iron pipe in water supply and fuel gas delivery, the advantages of the large-caliber nodular cast iron pipe compared with pipelines made of PE, PVC and the like are particularly obvious. Because the cost of iron accounts for more than 70% of the production cost of the heavy-calibre nodular cast iron pipe, the reduction of the waste of iron is the primary task of controlling the production cost and simultaneously conforms to the concept of constructing a resource-saving society.
In order to ensure that the molten iron is saved, the pipe wall can be cast uniformly and all accord with the wall thickness standard, and the molten iron amount poured out by turning over the ladle in the fan-shaped ladle is uniform and stable when the centrifugal machine casts the pipeline. At present, domestic cast pipe manufacturers all adopt hydraulic ladle turning devices on large-caliber cast pipe centrifuges, wherein most of the hydraulic ladle turning devices are in a hydraulic cylinder direct pushing mode, and the small part of the hydraulic ladle turning devices adopt a hydraulic cylinder + curve plate mode, but in any mode, the fan-shaped ladle turning angular speed and the moving speed of a hydraulic cylinder body are not in a linear relation, so that the angular speeds of the fan-shaped ladle when the fan-shaped ladle is lifted to different angles are different in the casting process of the same pipeline, the tapping speed is also different, and the thickness of the pipeline wall of the cast pipeline is uneven; to ensure that the minimum wall thickness also meets the standard, only the overall wall thickness is cast thicker.
