This page explains how Hearth Wall is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
The structural wall component that forms the interior boundary of a hearth or furnace chamber.
Technical details and manufacturing context for Hearth Wall
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Wall Thickness | 10–30 mm | Thicker walls improve thermal insulation and structural strength |
| Height | 500–3000 mm | Customizable to furnace chamber dimensions |
| Width | 500–2000 mm | Customizable to furnace chamber dimensions |
| Maximum Operating Temperature | 1200–1600 °C | Above 1600°C requires special refractory materials |
| Thermal Conductivity | 0.5–1.5 W/(m·K) | Lower values indicate better insulation |
| Density | 1.8–2.5 g/cm³ | Higher density improves strength but increases weight |
| Cold Crushing Strength | 30–80 MPa | Minimum strength to withstand furnace loadsISO 10059-1 |
| Thermal Shock Resistance | 10–30 cycles | Number of cycles before cracking under rapid temperature changesISO 11093-6 |
| Refractoriness Under Load | 1400–1600 °C | Temperature at which deformation occurs under loadISO 1893 |
| Weight | 500–5000 kg | Depends on dimensions and material density |
| Material Grade | A–C grade | Grade A for high-temperature zones, C for general useGB/T 2988 |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Atmospheric to 0.5 bar gauge (7.25 psi) internal pressure |
| other spec: | Thermal shock resistance: ΔT ≤ 300°C/min, erosion resistance: ≤1 mm/year at 15 m/s particle velocity |
| temperature: | Up to 1600°C (2912°F) continuous, 1800°C (3272°F) peak |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

Manufacturer profiles associated with Hearth Wall.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Common materials include refractory brick, castable refractory, and ceramic fiber. Each has different properties in terms of thermal insulation, strength, and resistance to thermal shock. The choice depends on the operating temperature and mechanical requirements.
Thickness affects thermal insulation and structural strength. The directory lists a typical range of 10–30 mm, but the actual thickness should be determined based on the furnace design, operating temperature, and required mechanical strength. Consult the manufacturer for specific recommendations.
The directory lists a range of 1200–1600°C. Above 1600°C, special refractory materials are required. The actual maximum temperature depends on the material grade and design. Always verify with the supplier.
Inspection frequency depends on operating conditions and manufacturer guidelines. Regular checks for cracks, spalling, or erosion are recommended. If any damage is found, repair or replacement should be considered to maintain performance and safety.
