Chamber Furnace is a high-temperature heating equipment with a closed furnace structure. It uses electric heating elements (such as resistance wires and silicon carbon rods) to achieve heat treatment processes such as sintering, annealing, ashing, and melting of materials in a controllable atmosphere. Its core advantages lie in high temperature uniformity (±2℃~±5℃), precise temperature control accuracy (supports multi-stage program heating) and strong operational safety. It is widely used in scenarios such as laboratory sample processing, small batch production, and scientific research experiments. Compared with traditional tube furnaces or pit furnaces, box furnaces have the characteristics of flexible loading, convenient maintenance, and adaptability to various sample forms (solid, powder, block, etc.). It is an ideal choice for high-temperature processing across industries.

2.2 Core Configuration and Performance Optimization
Heating System: U-shaped or corrugated resistance wire is evenly distributed around the furnace chamber to ensure temperature uniformity. High-temperature models (>1600°C) utilize silicon-molybdenum rod elements, offering enhanced temperature resistance and a 30% longer lifespan.
Temperature Control System: The PID intelligent controller supports 16 programmable temperature ramps and features a touchscreen interface that displays the furnace temperature curve in real time and supports data export (e.g., USB/RS485 interfaces).
Furnace Materials: Laboratory-grade models utilize lightweight ceramic fiber, increasing heating speed by 50% and saving 20% energy. Industrial-grade models utilize hollow alumina spheres for excellent insulation, maintaining an outer wall temperature below 60°C (at room temperature).

III. Chamber Furnace Industry Application Scenarios and Case Studies
3.1 Laboratory and Research Fields
Material Analysis: Used for annealing metal materials (e.g., stress relief annealing of copper alloys at 650°C ± 10°C) and sintering ceramic samples (sintering alumina ceramics at 1600°C for 2 hours). Sample Pretreatment: Ashing for soil heavy metal testing in environmental monitoring (ashing at 550°C for 4 hours to remove organic interference), in compliance with EPA 3050B standards.
3.2 Industrial Production
Electronic Component Manufacturing: MLCC (multilayer ceramic capacitor) sintering process. A box furnace uses a nitrogen atmosphere to achieve dense sintering of dielectric materials, increasing yield to 98%.
Medical Device Processing: High-temperature sterilization of stainless steel surgical instruments (134°C high-pressure steam sterilization + 300°C drying; the box furnace is compatible with the combined processing flow).
3.3 Customized Applications for Special Industries
Aerospace: Vacuum annealing of titanium alloy components. A box furnace with an integrated vacuum system (vacuum level ≤ 10⁻³Pa) prevents high-temperature oxidation and improves material fatigue strength.
New Energy Materials: Calcination of lithium-ion battery cathode materials (ternary material LiNiCoMnO₂). A box furnace with a precisely controlled heating rate (5°C/min to 900°C) ensures a stable crystal structure.

Core Selection Parameters
Temperature Requirements: Determine the rated temperature based on the sample processing process (e.g., 500°C–800°C for ashing, 1200°C–1800°C for high-temperature sintering).
Furnace Size: Calculate based on the single processing volume (e.g., if processing 50 20ml crucibles in a laboratory, a furnace volume of 30L or greater is recommended).
Atmosphere Control: If an inert gas atmosphere (e.g., nitrogen, argon) or vacuum environment is required, select a sealed furnace with inlet/exhaust ports.
