Abstract
Methods for producing pigs made of a metal alloy, wherein initially a melt is formed in which a basic material and one or several alloy components are present in the liquid state, from which the pigs are formed. In the course of cooling, energy in the form of a variable field, which increases the formation of mixed crystals, is briefly introduced into the melt prior to the formation of the pigs. A pig thereby produced is a cast piece formed from a basic material and one or several alloy components and has been formed from a melt into which energy had been briefly introduced by a variable physical field in order to increase mixed crystal formation.
Claims5
A method for producing pigs made of a metal alloy, wherein initially a melt is formed in which a basic material and one or several alloy components are present in a liquid state, from which the pigs are formed, comprising the steps of:
- loading the melt into a treatment chamber, which treatment chamber is heated to the range of the liquidus level of the metal alloy,
- cooling the melt,
- in the course of cooling the melt, increasing the formation of mixed crystals by introducing a supply of energy into the melt by means of a variable field prior to the formation of the pigs,
- detecting mixed crystal formation by measuring the dynamic viscosity of the melt in a treatment chamber,
- terminating the supply of energy into the melt after the process of mixed crystal formation has reached a predetermined optimum at which a further energy supply no longer decisively increases mixed crystal formation, and
- removing the melt from the treatment chamber and pouring it into pig molds.
