Melting Furnace Accessories – Overview

Boli Technology offers a comprehensive range of melting furnace accessories and spare parts designed to keep your melting operations running at peak performance-. From heating elements and thermocouples to crucible handling tools and induction coil components, every accessory is precision-engineered as a direct-fit replacement for our furnace systems—and compatible with most major furnace brands. Our accessories are manufactured from premium-grade materials including copper, stainless steel, brass, ceramics, and high-temperature alloys, delivering exceptional durability, corrosion resistance, and thermal stability in demanding industrial environments. Whether you need routine consumables, emergency replacements, or custom-engineered components, Boli Technology provides reliable, cost-effective solutions that minimize downtime and maximize productivity.

Heating Elements

Heating elements are the primary source of thermal energy in electric melting furnaces. Boli Technology supplies a full spectrum of heating elements crafted from high-temperature resistance wire, silicon carbide (SiC) rods, and molybdenum disilicide (MoSi₂) rods-. Our silicon carbide elements deliver exceptional durability and stable resistance characteristics for high-temperature applications, while MoSi₂ elements excel in extreme-temperature environments where oxidation resistance is critical. All elements are rated for continuous operation up to 1600°C, with customizable voltage options (220V/380V/440V) to match your specific furnace configuration.

Thermocouples & Temperature Sensors

Accurate temperature measurement is essential for safe and consistent furnace operation. Our thermocouple and sensor range includes Type K, Type N, and Type S thermocouples, selected based on your temperature range, furnace atmosphere, and required precision. Each thermocouple converts thermal energy into electrical signals, allowing your control system to regulate heating cycles with precision. Engineered to withstand oxidation, thermal shock, and mechanical stress in high-temperature environments, our thermocouples deliver reliable readings and long service life. Regular calibration and replacement help maintain furnace performance and product quality.

Crucibles & Handling Tools

Our crucible accessories line includes graphite and alumina crucibles in a wide range of sizes and specifications, designed to withstand temperatures up to 1800°C with excellent thermal shock resistance and chemical stability. Complementary handling tools—including crucible tongs, crucible lifters, crucible stands, and ladle bowls—ensure safe, efficient material handling during melting and pouring operations. We also supply crucible covers, spouts and spout extensions, muffle rings (which increase cold charge capacity and improve melt times), and crucible platters. All crucible accessories are manufactured from premium-grade raw materials under strict quality management systems.

Induction Coils & Electrical Components

For induction melting furnace systems, Boli Technology provides high-performance induction coils manufactured from specialized square copper tubing with a maximum thickness of 8mm to prevent deformation and breakage. Our coils feature high-strength resin bakelite insulating columns with M16 copper screws, phlogopite insulation layers to prevent carbonization and sparking, and DuPont anti-arc insulating paint coatings for extended service life. Each induction coil undergoes vacuum helium leak detection and triple pressure/water flow inspection before shipment. We also supply yokes, water-cooled cables, reactors, main control boards, and other critical induction furnace components.
