2500×1100×900mm Effective Size | Electric Bogie Hearth Furnace | Heat Treatment & Heating System for Small-to-Medium Metal Parts Below 950℃

1. Product Overview

This electric bogie hearth furnace has a rated temperature of 950℃ and normal operating temperature of 850℃, primarily used for heating and heat treatment of small-to-medium metal or alloy parts in air atmosphere, supporting quenching, annealing, tempering, and other processes. Featuring a full-fiber folded block lining and motorized bogie for automatic loading/unloading, it is suitable for small-to-medium batch, multi-variety heat treatment production.

2. Industry Challenges & Root Cause Analysis

Poor furnace insulation and high energy consumption:Traditional refractory brick linings have high heat capacity and poor insulation – slow heating with severe heat loss. Root cause: high thermal conductivity of lining materials, large heat storage loss – inadequate use of fiber structures.

Insufficient furnace temperature uniformity:Large temperature differentials across the chamber cause inconsistent hardness and microstructure within the same batch. Root cause: unreasonable zone division, unbalanced heating element layout, and poor sealing at door and bogie.

Cumbersome bogie and door operation:Traditional bogie traction relies on external winches – door lifting requires counterweights or pits – large footprint and inconvenient operation. Root cause: lack of integrated self-propelled bogie and compact door lifting design.

Difficult process data recording and traceability:Temperature curves cannot be automatically recorded – quality traceability relies on manual logbooks. Root cause: control system lacks data storage, export, and historical query functions.

3. Solution

3.1 Full-Fiber Folded Block Lining Structure:Furnace uses Shandong Luyang 1260 high-purity ceramic fiber folded blocks – density ≥230kg/m³, total thickness 325mm. Low thermal conductivity, strong shock resistance, erosion resistance – low heat storage loss, empty furnace heating rate ≤1h, empty furnace power loss ≤10% – significant energy savings.

3.2 Independent Zone Temperature Control with High Precision:2-zone independent control – Japanese Shimaden SRS3 intelligent program controller (with 485 communication) + SCR power regulator – control accuracy ±1℃, furnace uniformity ±10℃ (soaking stage). Each zone equipped with 3 ammeters for circuit current indication – each power regulator module with fast fuse protection.

3.3 Self-Propelled Bogie & Compact Door Structure:Bogie driven by 1.2kW cycloidal reducer directly on wheels – no external winch or pit required – smooth and reliable entry/exit. Furnace door lifted by 1-ton electric hoist (8m/min) with self-weight compression sealing – no counterweight – saves floor space.

3.4 Five-Sided Heating & Optimized Heating Elements:0Cr25Al5 resistance strip formed into corrugated shape – arranged on both sides of furnace chamber + bogie surface (five-sided heating). Strips processed with dedicated molds to prevent damage – fixed with ceramic screws – easy installation and maintenance. Heating main circuits with fast fuse protection – long service life.

3.5 Door & Bogie Electrical Interlock Protection:Transmission control with multiple interlocks – (1) bogie cannot move during heating; (2) heating only starts when door closed; (3) bogie moves only when door fully raised; (4) door and bogie movements protected by limit switches – ensuring operational safety.

3.6 Touchscreen Data Recording & Management:10.1-inch touchscreen with Shimaden controller – PID control and programmable process curves. Touchscreen records historical data, stores process curves, supports USB export and screenshot capture – over-temperature alarm function. 485 communication interface supports MES integration.

5. Selection Guide

5.1 Recommended Scenarios

  • Quenching, annealing, tempering of small-to-medium metal/alloy parts in air atmosphere

  • Batch heat treatment lines requiring fast heating and energy savings

  • Production scenarios with requirements for temperature uniformity and process data recording

5.2 Key Selection Considerations

  1. Workpiece size and load: Verify dimensions fit 2500×1100×900mm chamber – total weight ≤2 tons

  2. Process temperature requirements: Rated 950℃ – confirm process temperature within range

  3. Floor space: Allow space for door electric hoist and bogie entry/exit

  4. Data management needs: Touchscreen data storage and export meet traceability requirements – MES integration available

6. FAQ

Q1: What are the advantages of full-fiber lining over traditional refractory brick lining?

A: Full-fiber lining has low heat capacity and low thermal conductivity – fast heating (≤1h), empty furnace power loss ≤10% – significant energy savings. Fiber modules also offer thermal shock resistance and erosion resistance with long service life.

Q2: How is the bogie driven?

A: Self-propelled bogie – 1.2kW cycloidal reducer directly drives the wheels for entry/exit – no external winch or pit required – easy installation, space-saving.

Q3: How is furnace temperature uniformity ensured?

A: 2-zone independent control with resistance strips arranged on both sides and bogie surface for five-sided heating – combined with full-fiber lining insulation – uniformity ≤±10℃ during soaking – meets most heat treatment requirements.

Q4: What safety protection features are included?

A: Door and bogie electrical interlocks – bogie locked during heating, heating only with door closed, bogie moves only with door fully raised – all movements protected by limit switches. Heating circuits with fast fuse and overcurrent protection.

Q5: How can heat treatment process data be exported?

A: Touchscreen automatically records historical temperature data and process curves – data export via USB port, screenshot capture. 485 communication interface supports real-time MES data exchange.
