le blog À propos Mhitube Furnaces Boost Precision in Materials Research Industry

In materials science, chemical engineering, and industrial manufacturing, precise temperature control is critical for achieving specific process objectives. Without accurate thermal management, new material synthesis becomes unpredictable, and heat treatment processes cannot guarantee consistent product performance. MHI (MHI-INC), a specialized tube furnace manufacturer, offers horizontal tube furnaces with exceptional temperature control capabilities, versatile applications, and robust designs, providing reliable solutions for researchers and industrial engineers.

MHI horizontal tube furnaces are designed to deliver precisely controlled heating environments for diverse experimental and production needs. Key characteristics include:

• Wide temperature range: Models available with continuous operation up to 1760°C and momentary peaks at 1800°C
• Flexible zone control: Single-zone and multi-zone (single-tube or multi-tube) configurations with independent temperature regulation
• Advanced control systems: Fully programmable interfaces with high-precision temperature control, compatible with MHI-DACS data acquisition software
• Compact footprint: Bench-top installation saves laboratory or production space
• Durable construction: Stainless steel framework ensures long-term operational stability
• Atmosphere control: Capable of achieving 10 ^-5 Torr vacuum (dependent on temperature and tube type)
• Optional gas mixing: SIMGAS system for precise gas ratio control
• Quick-connect end caps: Facilitates configuration changes and maintenance

Designed for applications requiring high temperature uniformity:

• H14HT: 1400°C max, 2.5" diameter × 12" length heating tube
• H18-40HT: 1760°C continuous (1800°C peak), 2.5" diameter × 12" length
• 3H18-40HT: 1760°C max, optional 2.5" or 4" diameter × 27" length tubes

Ideal for processes requiring precise thermal gradients or multi-step reactions:

• 575H14HT: Single-zone, 1400°C max, variable tube sizes up to 4" diameter × 16-17" length
• 3H14HT2.5×27: Three-zone independent control, 1400°C max, 2.5" diameter × 27" length
• 3H18-40HT2.5×27: Three-zone, 1760°C (1800°C peak), 2.5" diameter × 27" length, upgradable to 4" diameter

Custom configurations include split-type (vertical/horizontal) furnaces, industrial-scale models, and innovative tilting/rotating designs.

These furnaces serve diverse sectors including:

• Advanced material synthesis (nanomaterials, ceramics, metals)
• Gas-phase reactions (catalysis, decomposition, reduction)
• Vacuum processing (annealing, sintering)
• Controlled atmosphere treatments
• Precious metal recovery
• Biomass pyrolysis and gasification
• Thermoelectric materials research
• Industrial heat treatment processes

MHI furnaces incorporate multiple control options:

• Electronic control panels with overtemperature protection
• MHI DACS software for data logging and process programming
• SIMGAS4 gas management for precise flow control

Multi-zone models typically feature HIPAN controllers with master/slave operation, while BPAN/XPAN controllers enhance temperature uniformity and programmed heating profiles.

Key factors for furnace selection include:

• Maximum operational temperature requirements
• Heating zone dimensions and uniformity needs
• Process tube diameter specifications
• Zone quantity (single vs. multi-zone)
• Atmosphere or vacuum requirements
• Control system sophistication
