Luoyang HongtengIntermediate frequency induction furnace
Mini type induction gold melting furnace Hongteng a professional induction furnace manufacturer had developed a mini-type melting furnace for gold melting recently. Compared to the furnace in the market, the Hongteng Medium frequency Induction melting furnace adopts a 3KW-7KW for the 1-3KG melting furnace. With this power configuration, melting time only needs 3-5 mins per batch. gold melting furnace Melting speed fast, and electrical inner setting with the higher standard component, Stable function. Easy to operating. Hongteng had designed carton packing and plywood case packing for air delivery and sea delivery. Good for machine protection and machine delivery cost. Welcome, contact us!
Mechanical Structure of Induction Coils Induction coils must be tightly coupled to the workpiece, but sufficient mechanical and electrical clearances must also be provided. Typically, a complete induction coil design with operating devices and matching components, such as capacitors and transformers, must be implemented. The design must also consider the effects of leakage flux heating, vibration, water, and oil; therefore, the induction coil should be manufactured after the electrical design is completed. The conductor is generally copper with high thermal conductivity and is cooled by water. Most induction coils consist of pipes with segmented water supply. However, sometimes oil or a “viscous” quenching medium can be used to achieve the dual function of cooling the conductor and quenching the workpiece. In some short-cycle, one-time spray quenching operations, the conductor may not be zoned for cooling because spray quenching can achieve both of these effects. Silver plating is often used to improve the surface thermal conductivity, especially at contact surfaces. A typical induction coil is shown. induction coils Most moving induction coils are single-turn and carry powerful currents up to 20 kA. Because reducing the voltage eliminates the risk of voltage breakdown in the presence of quenching media, a single-turn inductor...
Controlling a Prefabricated Atmosphere When metallurgists, engineers, and furnace operators refer to a controlled atmosphere, they are referring to a cold, externally prepared gas of a specific, constant composition, supplied to indirectly heated furnaces such as electric furnaces, radiant tube furnaces, and muffle furnaces. Most prefabricated atmospheres are currently prepared in separate gas generators, which may pass through H₂O and CO₂ absorbers before entering the heating chamber. Most generators utilize partial combustion of a gaseous fuel. Therefore, controlling the prefabricated atmosphere primarily involves maintaining a constant fuel-to-air ratio entering the generator and removing H₂O, CO₂, and other components after combustion over a catalyst. Efforts to reduce the amount of oxide scale formed on steel surfaces predate the term “prefabricated atmosphere” (Control of prefabricated atmosphere). Natural atmosphere As discussed earlier in this book, oxidation can be virtually avoided in a natural atmosphere, provided that a sufficient excess of fuel is present in the fuel-air mixture and the required temperature is maintained. An early example is the air curtain furnace, which appeared around 1927. Under very low air conditions, coal gas is burned in combustion chamber A. A pressure gauge B indicates the fuel-to-air ratio. Incompletely burned coal gas enters the heating...
Introduction to Industrial Furnaces and Their Energy Needs Definition and Core Function of Industrial Furnaces An industrial furnace is a thermal processing system designed to heat materials at extremely high temperatures for purposes like melting, drying, curing, or chemical transformation. Unlike household heaters, these units operate continuously under intense conditions, often exceeding 1,000°C (1,832°F). At its core, every furnace has three key parts: a heating chamber, a heat source, and a refractory lining that insulates and contains the heat. The control systems manage temperature profiles and atmosphere composition to ensure consistent results. According to CHE Furnaces, this precise thermal control is essential across industries where material integrity depends on exact heating cycles. Key Industries Relying on High-Temperature Processing Which sectors depend most on industrial furnaces? Metallurgy: Steelmaking, aluminum smelting, and heat treatment Glass Manufacturing: Melting silica sand into liquid glass Ceramics & Refractories: Firing bricks, tiles, and specialty ceramics Chemicals & Petrochemicals: Cracking hydrocarbons, reforming gases Waste Management: Incineration using fluidized bed or multiple hearth designs These processes require sustained, controllable heat—something only industrial-grade furnaces can provide reliably. Why Power Source and Heating Method Matter The choice between gas, electric, or hybrid power isn’t just about cost—it affects emissions, process speed, product quality,...
When running a rebar project or wire rod project, some customers may have the same problem, the electric power is not enough. Gas heating furnace In this condition, how do we save electric power? As we all know, in rebar projects, the power is mainly spent on scrap melting and billet heating part. So Hongteng Company suggests customer consider the Gas heating furnace. Gas heating furnace min loading capacity: 3T. suitable for big capacity 3-10T. Gas heating furnace structure: Pre-heating stage, Temperature holding stage, high temperature rasing stage. Material/Billet discharge: each time one billet Material /Billet size: 1-2M is regular size. 6M is also acceptable, just the furnace price will much higher. Billet transfer: if customers have demand, Hongteng also could customize the billet auto feeding system and transfer roller for client.
Design Efficient Steel Plants: Optimize Smelting to Heat Treatment If you’re involved in steel manufacturing, you know the pressure is on. Energy costs are rising, environmental regulations are tightening, and global demand for high-performance steel products keeps growing. So how do you stay competitive? The answer lies not in isolated upgrades, but in a holistic approach: Design Efficient Steel Plants: Optimize Smelting to Heat Treatment. This isn’t just about tweaking one process—it’s about rethinking the entire production chain as a single, integrated system. From raw material input to final heat treatment, every stage impacts the next. When designed with precision and synergy, modern steel plants can achieve unprecedented levels of efficiency, quality, and sustainability. Let’s walk through what that looks like in practice. Integrated Plant Design for Seamless Steel Production Understanding the Full Process Chain Think of your steel plant as a symphony. If each section plays independently—smelting here, casting there, rolling over there—the result is noise, not music. An integrated design ensures all instruments play in harmony. The full process chain begins with ironmaking (often via blast furnace or DRI), continues through steelmaking (like BOF or EAF), moves into continuous casting, then progresses through rolling, forging, and finally heat treatment....
