Since entering the 21st century, technological upgrades and the development of new products have become the cornerstone for survival in this century. So, have the industry-wide technological upgrades and new products you’re familiar with actually been realized? Today, let’s take a closer look at medium-frequency induction furnaces. Steel-shell furnace So, what are the advantages of medium-frequency induction furnace steel-shell furnace products? Many people may not be very familiar with this product.

Steel-shell furnace Body introduction

Steel-shell furnace enclosure frame, induction coil, furnace lid rotary cylinder, high-pressure carbon-free hose, casting and fixing materials for the furnace mouth and furnace bottom, complete stainless steel water distribution manifold, magnetic yoke, furnace lid, dust removal system, tilting furnace cylinder, return water collector and clamps, and more—including inlet and outlet stainless steel water distributors.

1. Power consumption of steel-shell furnaces: Steel-shell furnaces are equipped with magnetically permeable silicon steel sheets around the coil, which can recapture stray magnetic flux from the coil’s periphery and reuse it within the furnace chamber. In contrast, aluminum-shell furnaces lack such magnetic materials around their coils; therefore, steel-shell furnaces consume approximately 5% less electricity than aluminum-shell furnaces.

2. Steel-shell furnace Comparison of thermal resistance of casings: The temperature of an aluminum casing is relatively high when it reaches its normal melting point. If the cast aluminum quality is poor, the casing may crack after prolonged use. In contrast, the surface temperature of a steel casing remains consistent with the ambient room temperature at the time of melting.

3. Comparison of coil support strength in steel-shell and aluminum-shell furnace shells: The aluminum-shell coil is supported only by insulating posts and upper and lower steel tension rods; over time, the coil in large-tonnage electric furnaces will deform. In contrast, the steel-shell furnace features magnetic-conducting strips around its perimeter for support, ensuring that the coil remains free from deformation.

4. Comparison of Furnace Tilting Methods: Aluminum-shell furnaces typically use a gearbox-driven tilting mechanism. During tilting, the steel tapping process is less stable compared to that in steel-shell furnaces. Steel-shell furnaces, on the other hand, employ a hydraulic tilting system, ensuring a much smoother and more stable steel-tapping process during furnace tilting.

5. Comparison of service life: Aluminum-cased furnaces have a shorter lifespan than steel-cased furnaces.

6. Steel-shell furnace Cost comparison: Steel-cased furnaces are more expensive than aluminum-cased furnaces.
