Research of complex briquetted modifiers influence on cast iron properties

Such properties of cast iron as hardness and shock resistance are relevant and have been investigated. Some possible ways to improve these properties have been studied and solutions to the assigned tasks in accordance with modern trends have been found. The use of nano-dispersed modifiers is most promising in modification. The compositions of experimental complex briquetted modifiers have been developed. The technology of cast iron processing with complex briquetted modifiers has been developed. A series of experiments on the effect of a complex briquetted modifier introduced into cast iron on its properties were carried out. The rational content of components in the briquette that makes maximum use of the modifying effect and improves such service characteristics of cast iron as hardness, impact - and wear-resistance has been defined. Ways of a briquette destruction in metal have been explored. The effect of an organic binder amount on the de-struction of a briquette and its dissolution in the melt has been investigated. Rational composition of the briquetted modifier that makes it possible to increase hardness and impact resistance of cast iron has been developed
