Related Operations of Box-Type Furnaces

High temperature laboratory furnaces are easy to operate: equipped with a clear control panel (knobs, buttons, or touchscreen), and some models support PLC control.

Multiple safety features:

Overtemperature alarm and power-off protection: Automatically alarms and shuts off the heating power when the temperature exceeds the set value;

Broken-coupling protection: Stops heating in the event of a thermocouple failure, preventing temperature runaway;

Overcurrent/overload protection: Prevents short circuits or abnormal damage to the heating element;

Furnace door interlock: Cuts off heating when the door is opened, preventing injury from high-temperature radiation.

Adaptable to harsh environments: The High temperature laboratory furnaces's structure is dust-resistant and vibration-resistant, ensuring stable operation in industrial environments such as workshops and factories. Some models feature waterproof and corrosion-resistant designs (e.g., special treatments for humid or corrosive environments).

High temperature laboratory furnaces are widely used in industries such as mechanical manufacturing (parts quenching and tempering), metallurgy (metal annealing and aging), ceramics (commercial and industrial ceramic sintering), electronics (electronic component packaging and wafer heat treatment), and building materials (refractory firing). They are particularly well-suited for industrial production scenarios requiring batch processing and stable processes.

Common High temperature laboratory furnace structures on the market:

Box-type closed structure: The furnace body is a rectangular or cubic closed structure with a large furnace volume (typically ranging from tens of liters to several cubic meters), which can accommodate batches of workpieces or large samples and is suitable for industrial mass production.

Multi-layer insulation design: The furnace inner wall is often made of insulating materials such as high-density ceramic fiber, lightweight refractory bricks, or mullite. The outer layer is covered with cold-rolled steel plates or stainless steel, forming a multi-layer insulation structure, effectively reducing heat loss and lowering the furnace surface temperature (saving energy while improving safety).

Reasonable Heating Element Layout: Heating elements (resistance wire, silicon carbon rods, silicon molybdenum rods, etc.) are typically evenly distributed on both sides, top, or bottom of the furnace. Some models utilize a wraparound layout to ensure uniform temperature within the furnace (typically, the temperature difference is ≤±5°C to ±10°C, with some models achieving within ±3°C).

Sturdy and Durable Furnace Door: The furnace door features a heavy-duty panel and is equipped with high-temperature-resistant sealing materials (such as ceramic fiber wool and silicone seals) to ensure airtightness when closed. Some large-scale equipment features pneumatic or electric doors for automated operation.

In summary, High temperature laboratory furnaces, with their core features of large capacity, high stability, and strong adaptability, combine precise temperature control with industrial safety, and are key equipment bridging laboratory R&D and large-scale production.
