Industrial Electric Furnaces Frequently Asked Questions (FAQ)

1. What is the function of an industrial furnace?

Industrial furnaces are widely used in high-temperature smelting, heat treatment, and tempering in metallurgical production, as well as low-temperature drying and fermentation in some fields such as the food industry. The metal industry accounts for a significant share of total industrial energy consumption.

2. What is the difference between high-temperature and low-temperature furnaces?

High-temperature industrial furnaces typically operate at temperatures above 1200℃ and are used for ceramic firing, metallsmelting, pulvermetallurgi, etc.; low-temperature industrial furnaces operate at temperatures between 200-600℃ and are used for material drying, coating curing, adhesive treatment, osv. Users need to select the appropriate furnace type based on the process temperature.

3. Are industrial electric furnaces energy-intensive?

Modern industrial electric furnaces use full-fiber linings and multi-layer insulation structures, resulting in low heat storage and low heat loss, saving 30%-80% more energy compared to older refractory brick electric furnaces.

4. How are temperature control accuracy and furnace temperature uniformity guaranteed?

Equipped with an intelligent PID temperature controller or a multi-zone independent temperature control system, ensuring high temperature control accuracy. Large furnaces employ multi-point temperature measurement and zoned temperature control technologies, combined with hot air circulation or radiant panel layouts, to ensure uniform temperature within the furnace to meet process requirements (f.eks., ±5℃ or higher).

5. Is the furnace durable? Are maintenance costs high?

The lifespan of heating elements is affected by the heating rate, operating temperature, and atmosphere. The furnace lining material is resistant to rapid heating and cooling, and will not crack or shed slag.
