The Industrial Trolley Kiln Car Bottom Furnace Heat Treatment Machine is a specialized thermal processing equipment designed for heat treatment of metal parts in an oxidizing atmosphere. It adopts a "trolley kiln" structure—where the furnace bottom is a movable trolley that facilitates loading/unloading of heavy workpieces, making it ideal for batch processing of large, heavy metal components.

This machine integrates high-temperature heating, precise temperature control, and stable heat preservation, ensuring consistent heat treatment effects (such as hardness, toughness) for metal parts. It is widely used in machinery manufacturing, auto parts, pipe fitting processing, and casting industries, addressing the thermal processing needs of various metal components.

This heat treatment machine is mainly used for general metal parts heat treatment in an oxidizing atmosphere, with specific applications covering two key dimensions:

• Normalizing: Improves the microstructure of metal, enhances mechanical properties (strength, ductility), and reduces internal stress.
• Annealing: Softens metal materials, improves machinability, and eliminates residual stress from casting, forging, or welding.
• Quenching: Hardens metal parts by heating to austenitizing temperature and rapid cooling, enhancing surface hardness and wear resistance.

It is suitable for heat treatment of various mechanical parts and castings, including but not limited to:

• Wear-resistant components: Roller, steel ball, crusher hammerhead, chute liner.
• High-alloy castings: High chrome steel casting, high manganese steel casting.
• Iron castings: Gray iron casting, nodular iron casting.
• General mechanical parts: Shafts, gears, flanges, and pipe fitting components (matching our pipe fitting machinery for integrated processing).

The following are the specific technical specifications of the Industrial Trolley Kiln Car Bottom Furnace Heat Treatment Machine (model: RT3-120-9), ensuring clarity on performance and applicability:

• High Precision Temperature Control: Adopts PID intelligent control with ±1 °C temperature accuracy and ±5 °C furnace uniformity, ensuring consistent heat treatment effects for each workpiece.
• Large Capacity & Heavy Load: 2000*1000*1000 mm working size and ≤3T carrying capacity support batch processing, improving production efficiency.
• Energy Efficiency & Safety: Low empty furnace power loss (≤20 kw) and low furnace wall temperature rise (≤40 °C) reduce energy consumption and prevent scalding risks.
• Durable Components: 0Cr25Al5 heating elements and 3Cr18Mn12Si2N furnace plates ensure long-term stable operation, minimizing maintenance frequency.

• Integrated Solutions: For customers purchasing our pipe fitting machinery (e.g., elbow machines, tee machines), this heat treatment machine can form an integrated production line—covering forming, cutting, and heat treatment of pipe fittings, simplifying procurement and after-sales management.
• Global Service Support: We provide overseas installation guidance, operator training, and spare parts supply (e.g., heating elements, furnace plates) to ensure smooth operation of equipment in international markets.
• Customization Options: Based on customer needs, we can adjust parameters such as working size, maximum temperature, and carrying capacity to match specific production scenarios.

We welcome customers from the machinery, pipe fitting, and casting industries to explore cooperation with us, and look forward to providing you with high-quality heat treatment machinery and comprehensive solutions.
