How does the refractory plant do a good job in dust prevention and dust removal? do you understand? The editor of the electric arc furnace manufacturer tells you: First of all, let us know what kind of furnace the electricZBTECH News July 02, 2021
- ZBTECH obtained the CE certificate and entered the European market for the productsAfter years of innovation and development, our company has become an enterprise with both hardware and software strength in domestic Electric arc furnace industry. Our leading products cover three major industrial modules: Electric Arc Furnace (EAF), Secondary Refining Furnace and Ferroalloy FurnaceZBTECH News July 09, 2021
- Vacuum furnace of the structureThe pressure in the furnace chamber of the vacuum furnace can be pumped into an industrial furnace whose pressure is lower than atmospheric pressure. The vacuum furnace is heated by electricity, and the surface of the heated workpiece is not oxidized or decarburized, with small deformation and goodZBTECH News July 12, 2021
- Electric arc furnace(EAF) about the working principleArc is a kind of arc discharge of gas. Gas arc discharge shows that the voltage between the electrodes is very low, but the current through the gas is very large, there is dazzling white light, and the arc zone temperature is very high (about 5000k). The huge current density comes from the thermioniZBTECH News July 16, 2021
- EAF roof choose refractory materialsThere are many kinds of refractory materials for electric furnace cover, but no matter how the plan is, the refractory brick still requires good thermal shock resistance, corrosion resistance to slag high temperature splash, as well as integrity, and the most important thing is to ensure that the stZBTECH News July 14, 2021
- Vacuum degassing furnace---the common problemsThe vacuum degassing furnace first inhales the molten steel into the vacuum chamber and then blows argon gas into the molten steel on the side walls of the two risers. The argon gas expands rapidly under the action of low temperature and high pressure in the upper part of the vacuum chamber, makingZBTECH News June 30, 2021
- Vacuum arc furnace is a kind of vacuum metallurgical smelting equipment.Vacuum arc furnace is a kind of vacuum metallurgical smelting equipment. The furnace body is a closed container, pumped into a vacuum or filled with inert gas. An electric arc is generated after the electrode through the top of the furnace and the water-cooled crystallizer at the bottom of the furZBTECH News June 28, 2021
