- Optimization of EAF technologyWe have optimized the EAF technology to achieve the best balance among raw materials, scrap preheating, energy saving and environmental protection, process control, automation control, smelting cycle and production capacity.Electric energy is input into EAF through graphite electrode, and the arc beZBTECH News October 30, 2020
- Main functions of ladle refining furnace1. The function of increasing the temperature of molten steel and heat preservation. The molten steel obtains new heat energy through arc heating, which not only enables the addition of alloy and composition adjustment during ladle refining, but also the addition of slag material, which is convenienZBTECH News November 02, 2020
- Features of electric arc furnaceElectric arc furnaces use electric energy as their main energy source. Electric energy draws arcs through the discharge of graphite electrodes and the charge to generate a high temperature of 2000 ~ 6000 ℃ or more. The scrap steel raw materials are melted by arc radiation, temperature convection andZBTECH News November 09, 2020
- Ferroalloy furnace：how to solve the problem of rising temperature and redness of the furnace bottomTraditional ferroalloy submerged arc furnaces generally use pre-baked carbon blocks and wide and coarse-slit masonry linings, and adjust the primary current to control the electrode insertion depth in the furnace (that is, the electric furnace load). Take the main equipment of a company’s 2*25.5MVAZBTECH News November 20, 2020
- How to dust the boilerDue to the development of modern industry in the 21st century, new requirements for the quality of steel have been put forward, so almost all converters and electric arc furnaces are equipped with ladle refining furnaces.In the molten steel refining process, slag and alloy are added according to theZBTECH News November 04, 2020
- How does the LF ladle refining furnace perform secondary refining treatment on scrap steelChina produces about 200 million tons of iron and steel waste (such as trimming, trimming, scrapped machinery, household waste, etc.) every year. The LF ladle refining furnace is a kind of molten steel refining treatment device built after the primary furnace (converter, electric furnace). The LF prZBTECH News November 11, 2020
- Several characteristics of ladle refining furnaceLadle refining furnace is not often encountered in our lives. I believe many friends are very unfamiliar with it, but it is one of the main equipment for refining outside the furnace. The following is a summary of the characteristics of Zebang refining furnace manufacturer for everyone, let's learnZBTECH News November 06, 2020
