فرن الحفرة الصناعية

فرن الحفرة الصناعية

An industrial pit furnace is a vertical, deep-well structure of high-temperature heat treatment equipment, widely used in metal heat treatment, machining of long shaft workpieces, and heating of large workpieces. This type of pit furnace effectively saves space through vertical loading and achieves uniform and stable heating, making it one of the important furnace types in industrial production.

The equipment employs advanced heating and temperature control systems, making it particularly suitable for processing long or large workpieces, and it is widely used in the metallurgical and machinery manufacturing industries.

ميزات المنتج (فرن الحفرة الصناعية)

1. Vertical Deep-Well Structure, Designed for Long Components

This industrial pit furnace adopts a vertical deep-well furnace structure. Workpieces are loaded vertically from the top, effectively preventing bending and deformation at high temperatures.

2. Multi-Zone Independent Temperature Control, Uniform Temperature for Long Components

Multiple independent heating zones are set along the depth of the furnace chamber. Each zone can be set with its own temperature, effectively eliminating vertical temperature gradients. For long workpieces, it ensures consistent heating from top to bottom, resulting in excellent temperature uniformity.

3. التحكم الدقيق في درجة الحرارة, Excellent Process Reproducibility

Equipped with a PLC + touchscreen intelligent control system, the temperature control accuracy is ±1℃. It can store multiple process curves and monitor parameters such as temperature in each zone in real time. Historical data can be recorded and exported for easy process analysis and quality traceability.

4. Programmable Control, Fully Automatic Operation

Microcomputer program control, programmable curves, fully automatic heating/holding/cooling. Temperature control parameters and programs can be modified during operation, offering flexibility, convenience, and simple operation.

5. High-quality furnace lining for excellent heat preservation and energy saving

The furnace lining uses high-purity alumina fiber or mullite fiber materials, featuring a multi-layer composite insulation structure. It has low heat storage capacity, مقاوم للتسخين والتبريد السريع, and offers excellent heat preservation performance. The furnace shell temperature is ≤45℃, resulting in significant energy savings.

مجالات التطبيق (فرن الحفرة الصناعية)

• المعالجة الحرارية للبار: مناسبة للتليين, التطبيع, هدأ, and quenching of metal bars. Vertical placement effectively prevents bending deformation of long bars at high temperatures, ensuring straightness and consistent performance.
• Pipe Heat Treatment: Used for solution treatment, الصلب, and stress relief of metal and alloy pipes.
• Long Component Heat Treatment: Suitable for vertical heat treatment of long components such as long shafts, long screws, long sleeves, and lead screws, solving the problem of horizontal furnaces being unable to handle or easily deforming these components.
• Large Ring Heat Treatment: مناسبة للتبريد, هدأ, and annealing of large bearing rings, gear rings, flange rings, and other ring-shaped parts. Vertical hanging or stacking ensures uniform heating of the rings.
• المعالجة الحرارية السحابة: Suitable for quenching and tempering of long bolts, studs, and other long fasteners, ensuring consistent hardness along their entire length.
• قطع غيار السيارات: مناسبة للمعالجة الحرارية الدفعية لأجزاء العمود الطويلة مثل أعمدة قيادة السيارات, نصف مهاوي, ومفاصل التوجيه.
• Aerospace Components: Suitable for heat treatment of long components with strict requirements for dimensional accuracy and performance, such as aircraft landing gear components and long engine shafts.
• المعالجة الحرارية للقالب: Suitable for quenching and tempering of long molds.
• Metal Material Processing: مناسبة للصلب مشرق, التطبيع, and solution treatment of various steels and alloy materials; the protective atmosphere in the furnace ensures a bright, oxidation-free metal surface.

الأسئلة المتداولة (التعليمات)

1. What is an industrial pit furnace used for?

It is used for the mass heat treatment of vertically shaped workpieces such as long rods, shafts, والأنابيب.

2. What is the difference between an industrial pit furnace and a laboratory pit furnace?

Industrial pit furnaces are larger in size, deeper, and have a higher load capacity, making them suitable for large-scale production.

3. Is loading convenient?

نعم. Heavy workpieces can be easily loaded by vertically lifting them in from above using a crane or overhead crane.

4. How is the temperature uniformity?

جيد. Multi-zone temperature control ensures uniform temperature distribution along the depth direction.

5. Is it energy-efficient?

More energy-efficient than a box furnace. Hot air rises naturally and evenly, resulting in less heat loss.
