In ferroalloy smelting, large composition deviation, limited production capacity, and difficulty in utilizing low-grade ore have always been bottlenecks restricting profit growth; in the non-ferrous metal smelting field, low metal recovery rate, high energy consumption, and heavy pressure of environmental acceptance are even bigger “stumbling blocks” on the path of enterprise transformation. Targeting the core pain points of these two industries, Anyang Younengde DC Submerged Arc Furnace achieves three major breakthroughs of “precision smelting, cost reduction and efficiency improvement, and green compliance” with customized technical solutions, making it the preferred equipment for industrial smelting upgrading.
Exclusive Empowerment for Ferroalloy Smelting: Stable Composition, Sufficient Capacity, and Cost-Effective Raw Materials
For ferroalloy production enterprises such as ferrosilicon, ferromanganese, and ferrochromium, the precision of product composition directly determines market competitiveness. Relying on stable DC electric arc and submerged ore smelting mode, the DC Submerged Arc Furnace fundamentally solves the problem of composition fluctuation——the temperature field in the furnace is uniform without deviation, the control precision of alloy composition is ≤0.5%, and the rejection rate is directly reduced by 15%. It easily meets the customized production needs of high-end alloys and helps enterprises seize the high-end market.
In terms of production capacity, the equipment supports 24/7 uninterrupted continuous smelting, completely getting rid of the trouble of frequent furnace shutdowns and arc adjustments of AC furnaces. The daily output of a single furnace is increased by 20% compared with traditional equipment, perfectly adapting to the large-scale mass production conditions of ferroalloys. More notably, it has extremely strong compatibility with raw materials. It can directly smelt low-grade manganese ore, chromium ore and other low-quality ores without fine beneficiation, reducing the procurement cost of raw materials by 20%, turning “waste ore” into “treasure” and greatly broadening the profit space.
Core Advantages for Non-Ferrous Metal Smelting: High Recovery Rate, Low Energy Consumption, and Easy Compliance
The core demand of non-ferrous metal smelting is “efficiency improvement and income increase, cost control”, and the DC Submerged Arc Furnace precisely meets this demand. Its high-temperature, concentrated and stable electric arc environment can effectively avoid oxidative burning loss of metals such as copper, aluminum and zinc. The metal recovery rate exceeds 98%, which is 8%-10% higher than that of traditional AC furnaces; when processing copper anode slime, tin dross and other wastes, it can also simultaneously improve the extraction rate of rare and precious metals, allowing every part of the raw material to fully release its value.
In terms of cost control, the natural power factor of the equipment is as high as 0.95-0.98, eliminating the need for additional reactive power compensation devices and directly reducing electricity consumption by 20%; at the same time, submerged arc operation reduces electrode oxidation, extending the electrode service life by 35%. Taking a 1000kVA equipment as an example, the annual consumable cost can be saved by more than 300,000 RMB (about 42,000 USD), realizing “meticulous” cost reduction. In terms of environmental protection, the submerged arc in the furnace material greatly reduces unorganized emission of flue gas, reducing the smoke concentration by 40% and carbon emission per ton of product by 60%, easily passing the environmental acceptance and perfectly adapting to the policy requirements of recycled non-ferrous metal recovery.
Universal Guarantee for All Industries: Low-Cost Upgrade, Full-Process Support
Considering the cost concerns of enterprise upgrading, Anyang Younengde launches a minimally invasive transformation plan for existing AC submerged arc furnaces. The transformation cost is only 30%-50% of that of purchasing new equipment, with an average payback period of only 6-12 months, enabling significant improvement with small investment. At the same time, relying on 20 years of industry experience and more than 920 successful project cases, the team provides enterprises with full-process services——from process customization, on-site installation and commissioning to 24/7 online after-sales response, comprehensively ensuring the stable operation of the equipment. It also promises that the service life of the transformed equipment will be extended by 8-10 years, allowing enterprises to upgrade without worries.
Whether it is precision smelting and large-scale mass production of ferroalloys, or efficient recovery and green compliance of non-ferrous metals, the DC Submerged Arc Furnace can solve pain points and empower efficiency improvement for enterprises with targeted technical advantages. At present, the equipment has been widely used in various smelting projects and has become a core equipment for many enterprises to reduce costs and increase income.
