Product Description
Mixed alloy steel ingot butts scrap consists of the bottom crop ends, discards, and solidified pour heels produced during the ingot casting and teeming operations of low-alloy and medium-alloy steel ingots. Highly valued in heavy steelmaking and metal recycling for its solid density and massive unit weight, this material provides a primary iron charge along with recoverable nickel, chromium, molybdenum, and manganese content.

Industrial Applications
-
Primary Electric Arc Furnace Charging: Serves as high-density heavy melting scrap placed at the bottom of furnace charge baskets to protect furnace hearth linings and accelerate initial melt-down rates.
-
Foundry Furnace Charging: Used by heavy steel foundries as a dense melt charge to efficiently build bath volume in large-capacity induction furnaces.
-
Secondary Metallurgy Alloy Recovery: Acts as a cost-effective bulk charge material that introduces foundational nickel, chromium, and molybdenum units into the melt bath prior to final ladle composition tuning.
