Introduction to Cast Iron Material:

① Gray cast iron. The carbon content is relatively high (2.7% to 4.0%), and the carbon mainly exists in the form of flake graphite, with a gray fracture surface, abbreviated as gray iron. During solidification, the shrinkage is small, the pressure and hardness are close to carbon steel, and the shock absorption is good. Used for structural components such as machine tool beds, cylinders, and casings.

② White cast iron. The carbon and silicon content is relatively low, and carbon mainly exists in the form of cementite, with a silver white fracture surface. During solidification, there is significant shrinkage, which can easily lead to shrinkage and cracking. Hardness, high brittleness, unable to withstand impact loads. It is commonly used as a blank for malleable cast iron and in the production of wear-resistant components.

③ Malleable cast iron. Obtained by annealing white cast iron, graphite is distributed in a flocculent form, abbreviated as ductile iron. Its organizational performance is uniform, wear-resistant, and has good plasticity and toughness. Used for parts with complex shapes that can withstand strong dynamic loads.

Gray cast iron weight: Most or all of the carbon in this type of cast iron exists in the form of free graphite flakes, with a dark gray fracture surface. It has certain mechanical properties and good machinability, and is widely used in industry.

Advantages of cast iron weights - surface smoothness, rust resistance, and inspection quality

In modern quality measurement, weights are measuring tools used to transmit the value of mass. The quality value is based on the platinum iridium alloy kilogram prototype stored in France. Each weight is divided into kilogram reference, kilogram sub reference, kilogram working reference, as well as working reference groups composed of multiples and components of kilograms and various working weights.

Generally classified by material: stainless steel weights, cast iron weights, copper weights, etc., of course, this is only a large category, further subdivision is also used, non-magnetic weights and magnetic weights, etc

Weights are divided into three sizes: large weights, laboratory weights, and measuring weights.

Weights can be divided into irregular weights and standard weights based on their shape.

Cast iron weight shape: Conventional lock type weights weighing less than 500KG are standard. The 500KG-5T standard has a square shape and can be forked off for both use. There are also cylindrical and circular rollers, which can be customized according to the drawings.

Cast iron weight material: Gray mouthed iron poured with pure molten iron, steel coated weight (outer steel plate with internal iron block)

Cast iron weight grades: M1 grade, M2 grade, M12 grade

Usage: This product is suitable for use as a calibration device for weighing instruments, ports, and electronic belt scales. It is used for the calibration of various industrial scales such as electronic scales, iron scales, electronic flat scales, elevators, etc., to ensure the accuracy of the scale body. It is also used for experiments! The function of cast iron weights: Standard cast iron weights are mainly used for calibrating electronic scales, such as electronic platform scales, electronic floor scales, electronic hanging scales, electronic forklift scales, electronic truck scales, etc.

Grey cast iron weightsFactors affecting performance

① The influence of chemical composition. The main focus is on controlling the mass fractions of carbon and silicon. Low carbon and silicon mass fractions make cast iron prone to white cast structure, resulting in low mechanical and casting properties; When the mass fraction of carbon and silicon is too high, there are too many and coarse graphite sheets, and even graphite floating on the surface of the molten iron, which reduces the performance and quality of the castings. Therefore, the carbon and silicon content in gray cast iron is generally controlled at 2% to 4% C, 1.0% to 2.0% Si; 0.5%～1.4%Mn。

② The influence of cooling rate: Under the casting process conditions, the cooling rate of castings has a significant impact on the degree of graphitization. As the wall thickness of the casting increases, the cooling rate slows down and carbon atoms have diffusion time, which is conducive to the graphitization process. At room temperature, the structure is prone to form gray iron structure; However, if the cooling rate of thin-walled parts is too fast during the cooling process, it is easy to form white cast iron structure.
