2019年12月19日 · 「電爐」全名為 電弧爐 Electric arc furnace （簡稱EAF）。 電爐煉鋼可追溯至西元1898年的史達塞諾電弧爐，而現今較普遍使用的則是1912年靈耐飛特電弧爐，其電極昇降之操作、以及鋼液溫度調整較為方便容易，是相當重要的煉鋼技術之一，台灣的煉鋼業發展也以 ...

Production of high-alloy special steels in the electric arc furnace (EAF) requires the use of several different melting practices — from standard foaming slag operation through recovery heats with no foaming slag, to heats with large amounts of FeCr charged into the furnace after earlier phosphorus removal.

2020年6月10日 · In an EAF, slag line area and the hotspot in wall are the most critical zones. Special attention is taken in selection of refractories in hotspot areas as the life of furnace wall depends on the high erosion of hotspot areas.

2024年2月16日 · The purpose of supplying oxygen to the furnace wall of the EAF is to eliminate the cold zone in the furnace and to ensure the balanced melting of the charge. The modularized control of the furnace wall is used to inject pure oxygen to increase the specific power input of the EAF steelmaking and improve production efficiency .

We will explain the characteristics of our newly developed EAF refractories using typical examples. By applying sidewall refractories with high corrosion resistance, HIDEN and EBT tube, bottom blowing nozzle, slide gate valve for tapping, ABB type bottom electrode in DC furnace, and high slaking resistant bricks for back lining.

Production of high-alloy special steels in the electric arc furnace (EAF) requires the use of several different melting practices — from standard foaming slag operation through recovery heats with no foaming slag, to heats with large amounts of FeCr charged into the furnace after earlier phosphorus removal.

An electric arc furnace (EAF) isa furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondarysteelmaking.

4 天之前 · Spray-cooled shells of electric arc furnaces (EAF) experience dynamic and intense thermal fluctuations that, if undetected, can lead to significant operational challenges, including structural damage and compromised safety. In this study, we demonstrate the use of fiber optic sensors (FOS) for real-time, distributed thermal monitoring of an EAF shell wall.

The equipment on board of the EAF shell can be made up of four different tools. Each injector has been developed to satisfy a very specific requirement of the melting/refining process: Fines Injection: For deep injection of fines at high speed. This equipment injects the fines shrouded by an annular supersonic stream of oxygen.
