ALLOY   DIVISION

With minimal manpower, our automated plant can produce up to 12,000 NT of briquetted product per month. Our raw material batching system can handle 7 ingredients at a time, with weighing tolerances of +/-5 lbs. per ingredient, allowing us to make finely tuned, specialized mixes for our customers' unique needs or simply binding materials too fine to be used in their current condition into a dense recyclable product.

Computerized batch calculations, exhaustive in-house QA chemistry checks, and routine third-party laboratory checks help to ensure consistent high quality.

The R.I. Lampus Co. Alloys Division specializes in producing standard and custom alloying agents and de-oxidants for the iron and steel industry. Its state-of-the-art, automated plant, is capable of converting many fine materials into easily handled, low surface area blocks using a Portland cement binder.

R.I. Lampus Company alloy products are used successfully in a variety of areas and industries. These include:

Tolling Services:
The R. I. Lampus Company can process materials that are too fine to be used in their current condition, and return the material in an easily handled, dense, low surface area form.

Integrated Steel Mills:
Briquetted silicon carbide slabs are commonly charged into Basic Oxygen Furnaces as a hot metal extender and fuel source. The heat generated by the burning of SiC allows a greater percentage of steel scrap to be used in the BOF charge. The silicon carbide can also be used to bring a heat back to temperature if cooling has occurred during a delay.

Electric Furnace Shops:
In stainless and carbon steel Electric Arc Furnace shops, granular silicon carbide can be used as a slag de-oxidant. The R. I. Lampus Co. also processes arc furnace mill recyclables of all kinds to address ever-changing environmental and economic demands placed on the end customer.

Iron Foundries:
R.I. Lampus Co. briquetted products are used extensively in iron foundries. In cupola melting, the briquettes serve primarily as an alloying source, providing silicon and if desired, chromium and manganese, although additional alloying agents are available. Spar additions are sometimes made to influence the fluidity of cupola slags. Carbon and/or silicon carbide additions, act as supplementary fuel sources to the coke charge and can increase melt rates.

 In coreless furnace melting, our bagged 90% Silicon Carbide Grain is routinely used as a silicon source and de-oxidant. Our bag weight control of +/-1 lb per 50 lb. bag helps to ensure that the melt shop experiences no surprises in recoveries.
