- Steelmaking electric furnace: introduction to the advantages of the water-cooled furnace coverThe existing furnace covers of steel-making electric furnaces mostly adopt the structure of masonry refractory bricks. The disadvantages of the furnace covers of this structure are many brick cracks, poor overall performance, high energy consumption, short service life, and long maintenance.The purpZBTECH News December 11, 2020
- What are the characteristics of ferroalloy submerged arc furnace1. Energy saving: The production of ferroalloys accounts for a large proportion of electricity consumption, so reducing power consumption and increasing the cost of thermal efficiency is an effective way to reduce the production cost of ferroalloys.At present, the actual power consumption of myZBTECH News December 09, 2020
- Electric arc furnace steelmaking: main technological processes and development trendsElectric arc furnace steelmaking is the main method for producing medium-high alloy steel and high-quality steel.In energy and resources, more waste and cheap industrialized areas, electric arc furnaces produce ordinary carbon steel, which has accounted for market share growth.With the developmentZBTECH News December 07, 2020
- How to prevent early failure of carbon lining for ferroalloy furnaceInventory the currently used carbon furnace lining masonry methods, nothing more than these three: carbon brick seamless method, carbon brick wide seam method, cold ramming and paste integral ramming method. These three methods all have their own disadvantages and weaknesses.Today, we introduceZBTECH News December 04, 2020

- Improve the age of DC electric arc furnaceAccording to the development trend of electric furnace steelmaking and the trend of general contracting of refractory materials, we should pay attention to refractories for electric furnaces as general contracting of refractory materials.The life of electric smelting furnace is not only closely relaZBTECH News November 30, 2020
- Introduction of Electric Arc FurnaceElectric arc furnace uses the high temperature generated by the electrode arc to smelt ores and metals. When the gas discharge forms an arc, the energy is very concentrated, and the arc zone temperature is above 3000 ℃. For smelting metals, electric arc furnaces are more flexible than other steelmakZBTECH News October 19, 2020
- Electric arc furnace's development historyFrench Heroult (P.L.T.Héroult) used the high temperature of the electric arc of the electrode to develop an alternative energy source for coal and invented the electric arc furnace for industrial direct smelting from 1888 to 1892. At first, the electric arc furnace was only used for the production of calcium carbide and ferroalloys. It was not until 1906 that it was developed for steelmaking, which enabled the economical and large-scale recycling of steel scrap.ZBTECH News October 21, 2020
- How an electric arc furnace work?Electric Arc Furnace Arc furnace provides a simple and effective way of melting various grades of scrap and then going ahead to refine the metal to desired specification. It is also useful in making all kinds of steels including tool steels and alloy steels. This provides a method of utilising lZBTECH News October 06, 2020
- Electric arc furnace's 4 classification methodsThere are many ways to classify electric arc furnaces.According to the melting form of the electrode, it is divided into(1) Non-consumable electrode type electric arc furnace, which uses tungsten or graphite as the electrode, and the electrode itself is not consumed or consumed very little during thZBTECH News October 23, 2020
