Product Introduction

SG370/17 lost wax investment casting

Nodular cast iron is obtained by spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially the ductility and toughness, so as to obtain higher strength than carbon steel. Ductile iron is a kind of high strength cast iron material developed in the 1950s, its comprehensive performance is close to steel, it is based on its excellent performance, has been successfully used to cast some complex forces, strength, toughness, wear resistance requirements of high parts. Ductile iron has rapidly developed into a cast iron material second only to gray iron and widely used. So called " Replace steel with iron " Mainly refers to ductile iron.

For the current development of China's machinery industry, its development is very fast, which is the best development of nodular casting, nodular casting with its excellent mechanical and specific properties, has been well developed in the industry, it can be a variety of mechanical needs have different strengths, as well as hardness and toughness, nodular casting can also have a variety of special properties. Molding core process is one of the key processes in the formation of nodular casting, which has a very important impact on the quality of nodular casting, manufacturing cost, production efficiency, labor intensity and environmental pollution. Years of practice, clay sand wet modeling process, with low cost, low pollution, high efficiency, good quality, automation, high density humidity, and many other advantages, has been favored by users, and China's future ductile casting plate production development trend is also clay sand wet sand modeling process. The so-called good sand effect mainly refers to that the sand is easy and simple, the cutting is sharp and wear-resistant, and the sanding property is good: the plate is easy to sanding, the embedded sand is firm and durable, the quality of the ductile ink plate, do not be cheated by small and cheap, and the sand pressing of the ductile ink casting is very important in the repair amount of the measuring block. Its master includes what sand pressing method is taken by the plate sand pressing, how to grind and the problems that occur in the process of ductile casting, and how to solve them. Nodular casting base surface change is also the main factor affecting nodular casting, nodular casting plate in the transformation to follow the principle is: after the base surface change, because the measurement direction is always perpendicular to the measurement datum. When the ideal plane or the measured profile rotates around an axis, the increase or decrease of the height value of the points on both sides of the rotation axis is proportional to the distance from each point to the rotation axis. The base plane transformation reflects the translation or rotation of the reference plane by increasing or decreasing the value of the original data. That is, a certain value can be added or subtracted from the measurement data, and the flatness error is calculated according to the difference between the * high point and * low point, so the base plane translation has no effect on the evaluation result.
