High Temperature 1200C 1400C 1700C Industrial Laboratory Melting Furnace Electric Portable Box Furnace

The product line includes models rated for 1200°C, 1400°C and 1700°C. The specification sheet lists a 1200°C model with a continuous operating temperature of 1150°C. Confirm the specific model you need when ordering.

Temperature control is PLC‑based with an N‑type thermocouple and a stated temperature accuracy of ±1°C (model and conditions dependent).

The furnace is specified for 380V supply. This typically means three‑phase power; confirm required current, phase and frequency with the seller or an electrician before installation.

It uses a high‑quality alloy resistance wire heating element designed for high‑temperature operation and durability.

Yes — higher‑temperature models (e.g., 1400°C and 1700°C) can melt many non‑refractory metals. Examples: aluminum (≈660°C), copper (≈1085°C), silver (≈962°C), gold (≈1064°C), and many steels (melting varies, often 1370–1530°C). It cannot reliably melt very refractory metals (e.g., tungsten) without specialised equipment.

The standard box furnace is designed to operate in ambient air. Controlled atmospheres (inert gas, vacuum) require special seals, ports and gas handling modifications—ask the manufacturer for a modified or dedicated atmosphere version.

The furnace is described as compact and portable for transport, but the specification lists a weight of 0.3 T (approximately 300 kg). This requires appropriate handling equipment (forklift/crane). Verify shipping/package weights with the supplier.

Listed overall dimensions are 400 × 600 × 400 mm. Some packaging entries in the spec (e.g., 10 × 10 × 10 cm or a 30 kg single gross weight) appear inconsistent—please confirm actual shipping dimensions and weight with the vendor prior to purchase.

Typical safety features include thermal insulation, over‑temperature protection, grounding provisions and emergency stop via the PLC. Required precautions: install on a non‑combustible surface, ensure proper grounding and ventilation, follow lockout/tagout for maintenance, and use appropriate PPE (heat‑resistant gloves, face shield). Follow local electrical and fire codes.

Crucible selection depends on material and temperature: graphite crucibles are common for many metal melts (in inert atmospheres), alumina or zirconia crucibles for oxide ceramics and high‑temperature work. Always choose a crucible material compatible with the melt chemistry and maximum temperature. Consult the manufacturer for recommendations.

Heating rate depends on the model, installed power, setpoint and the mass of the load. The product listing does not provide a specific °C/min value—request the heating ramp performance or data sheet from the supplier for the exact model and typical loads.

Regular maintenance includes keeping the chamber clean, inspecting and replacing worn heating elements and thermocouples, checking door seals, verifying controller calibration, and ensuring electrical connections are tight. Follow the manufacturer's maintenance schedule and procedures.

The specification lists ISO9001 certification (quality management system). For electrical or safety certifications (CE, UL, etc.), check with the manufacturer or supplier as those are not listed in the provided specification.

Most suppliers offer spare parts (heating elements, thermocouples, controllers) and technical support. Confirm availability, lead times and warranty/support terms with your vendor before purchase.

Prepare a stable, non‑combustible installation surface, 380V electrical supply with correct amperage and protection, adequate ventilation or fume extraction, and sufficient clearance for safe operation and maintenance. Because of weight, arrange handling equipment for placement. Consult the supplier's installation manual for exact electrical and clearance requirements.
