Date:2020/3/27 Source: CISDI

CISDI’s expertise in green and ultra-efficient electric arc furnaces has won the company a national technological prize.

The electric arc furnace melting process is key to the scrap re-utilisation industry. It consumes two thirds less energy and produces only a third of the carbon emissions of the blast furnace - basic oxygen furnace integrated process and is an important new method for metal recycling.

EAF melting is already playing a vital role in China’s steel re-engineering programme.

It took CISDI over a decade to develop its world-leading green, high-efficiency EAF.

Having partnered with other organisations, CISDI addressed the issues which occurred in the all-scrap-charged EAF melting process - high energy consumption, unstable quality and dioxin pollution.

CISDI’s green model features an ultra-high-powered intelligent power supply system and an efficient and ultra-clean melting process.

In addition, the EAF has an eco-friendly scrap transport and pre-heating system and an efficient, coordinated control system.

The EAF’s UHP intelligent power supply and the eco-friendlier melting process have achieved top global indicators.

The green EAF has been widely promoted to markets in China and abroad and has been exported to Russia, Italy, Turkey and Indonesia, where it is demonstrating tangible social and economic benefits.

It has been awarded 20 invention patents, 37 patents for utility, five software copyrights and three applications for the WIPO’s Patent Co-operation Treaty (one licensed).

Patents have also been granted by the EU and Japan.

In addition, eight standards have been formulated, two of which are international, four are national and two are industrial.

Some 91 papers have been published, including 34 under the Science Citation Index.

The EAF award is the second of its kind in China. The first award was also won by CISDI in 2016 for its high-efficiency, low-consumption mega blast furnace expertise and equipment.
