Ductile iron product quality is how to make?
Ball mill is one of the important products of our company long-term production of cast iron, senior experts said, the excellent quality of nodular cast iron products can be done, not to say do it needs through various aspects reason after comprehensive consideration, analysis, design and standard, can produce excellent ductile iron casting
As small make up to introduce the nodular cast iron under the product quality is how to do?
1, the design of ductile cast iron parts manufacturability, the workpiece design requirements in rational optimal scheme should be adopted when, in addition to according to the working conditions and the metal material performance to determine the casting geometry shape, size, also must from the perspective of the casting alloy and casting characteristics to consider the rationality of the design, avoid all kinds of bad phenomena appeared in the process of production.
2, the product of the casting process, also need to combined with the characteristics of materials and production conditions, product structure, size and weight to be determined.
3 and correct selection of raw materials and quality assurance, in the production of ductile iron parts in addition to want to use the corresponding raw material of cast iron, have nodularizer, furnace charge, refractory materials, fuels, solvents, inoculant, casting sand, sand adhesive, coating and other materials, each must choose carefully, do not allow any negligence.
4, the ability of operating personnel, this also is one of the important factors that influences the quality of ductile iron parts, the more at ordinary times should strengthen production and technical personnel training, improve the casting.
5, the enterprise production management to ensure that each work process can do, regardless of any adverse factors.
No factory is the domestic high quality foundry, mainly produces mining wear-resisting castings, carbon steel, low alloy steel castings, such as pieces of gray cast iron castings products, dedicated to the broad masses of customers to provide quality products.
