SLag Cleaning (CL) Furnace

Kubota Metal Corporation is a foundry and metals fabricator located in Orillia, Ontario. Kubota supplies alloy-steel castings and assemblies for many industries, including; direct reduced iron, industrial furnace, pulp & paper, petrochemical, aluminum, nuclear, cement, mining, and steel. Kubota produces a wide range of alloys, including heat-, corrosion-, and abrasion-resistant grades, as well as carbon and low alloy - high strength steels. Most of the alloys produced are proprietary.

Heat-Resistant Alloys

Conditions in metallurgical furnaces can be extremely hostile and diverse. Stresses may be compressive, tensile, hoop, bending, cyclic, or combinations of these. Atmospheres may be oxidizing, carburizing, or highly corrosive due to compounds of sulphur, chlorine, vanadium, or sodium. Component temperature may approach the melting point of some alloys or be subjected to abrasive wear by impact, sliding, or gouging.

Kubota manufactures the vertical top blown lances for the Smelting (S) Furnace and the Converting (C) Furnace in the Mitsubishi Process for copperproduction. High-chrome steel alloys are used for this application. In general, high-temperature alloys are based on mixtures of nickel, chromium, and iron; along with additions of modifying elements including aluminum, cobalt, molybdenum, niobium, rare earths, titanium, tungsten, and zirconium.
