1800°C High-Temperature Furnace | DFHH-15, DFHH-20 & DFHH-303
1800°C High-Temperature Furnace
DFHH-15, DFHH-20, and DFHH-303 1800°C furnaces are designed for ultra-high-temperature use with ceramic, metal, electronic, and powder materials, including sintering, ash analysis, heat treatment, and R&D testing. They use a 16-segment programmable controller for heating and cooling ramp control, with S.C.R. phase control, a B-type thermocouple, and molybdenum disilicide heating elements. Select a model based on sample size and material, loading method, target temperature, hold time, and available power.
1800°C Ultra-High Temperature Range
Rated to 1800°C with a common operating temperature of 1650°C; suitable for sintering, ash analysis, heat treatment, and material testing requiring higher temperatures.
16-Segment Program Control
The 16-segment programmable controller provides heating and cooling ramp control for processes requiring staged heating, holding, or cooling.
Molybdenum Disilicide Heating Elements
Uses molybdenum disilicide heating elements. The chamber is lined with imported high-temperature fiberboard and insulated with ceramic fiberboard and ceramic wool.
How to Choose an 1800°C Furnace
When choosing an 1800°C furnace, consider sample dimensions and quantity per batch, target temperature, hold time, heating and cooling ramps, possible outgassing, available power, and installation space. DFHH-15 suits small samples; DFHH-20 suits small-to-medium samples or deeper loading; DFHH-303 suits larger samples or applications needing more chamber space. Confirm selection based on the sample, test objective, and quality-control process.

Frequently Asked Questions
Q1: How do I choose between DFHH-15, DFHH-20, and DFHH-303?
Choose based on chamber size, sample dimensions, batch quantity, and available power. DFHH-15 has a 15 x 15 x 15 cm chamber for small samples; DFHH-20 measures 20 x 25 x 20 cm for small-to-medium samples or deeper loading; DFHH-303 measures 30 x 30 x 30 cm for larger samples or higher batch capacity. Confirm the final choice for the sample and process.
Q2: What applications suit an 1800°C furnace?
Applications include ceramic sintering, metal heat treatment, powder processing, high-temperature testing of electronic materials, ash analysis, R&D, and quality inspection. Confirm suitability based on material, target temperature, hold time, and process.
Q3: Should I choose an 1800°C or 1600°C furnace?
If routine temperatures are mostly below 1400°C, consider a 1600°C furnace. For higher-temperature sintering, special ceramics, powder materials, or ultra-high-temperature heat-treatment testing, consider an 1800°C furnace. Base selection on the sample and test objective.
Q4: What can the 16-segment programmable controller do?
It controls heating and cooling ramps for material testing and heat-treatment processes that require staged heating, holding, or controlled cooling. Confirm programming details for the controller and application.
Q5: What information should I provide for a quote?
Please provide sample material, dimensions and weight, batch quantity, common and maximum temperatures, hold time, ramp requirements, available power, and installation space so we can assess a suitable model.
Specifications are based on available product information. Confirm operating conditions, chamber dimensions, controller settings, power, customization, and supplied configuration for the model and application.
