Abstract
Disclosed is a balance weight of steel and heavy concrete components and a production method for the balance weight, as an alternative to pig casting and spheroidal graphite casting.
Claims4
A balance weight composition for use in applications that require a casting weight, the balance weight composition comprising:
- sheet steel between 10% and 60% by weight of the balance weight composition;
- a concrete mixture between 40% and 90% by weight of the balance weight composition, wherein said concrete mixture comprises cement between 10% and 30 by weight, iron ore between 20% and 30% by weight, scale between 20% and 60% by weight, and aggregates between 5% and 10% by weight, wherein said sheet steel and said concrete mixture are no more than 100% by weight of the balance weight composition, wherein the cement and the iron ore and the scale and the aggregates are no more than 100% by weight of the concrete mixture.
A method of producing a balance weight for applications that require a casting weight, the method comprising:
- processing and shaping a sheet material with at least one of hydraulic pressing, hydroforming and deep drawing;
- forming an outer shell by joining the processed and shaped sheet material of at least two pieces with a weld;
- producing a heavy concrete;
- filling the outer shell with the produced heavy concrete;
- curing the heavy concrete after the step of filling the outer shell with the produced heavy concrete so as to have a filling opening of the cured heavy concrete;
- closing the filling opening by welding the processed and shaped sheet material;
- and
- dyeing the balance weight with a dye preparation.
