Ultra-high-power electric arc furnaces mainly use arcs to heat and melt scrap steel.
READ MORELarge capacity and ultra high power electric arc furnace and large furnace refining technology have become the symbol of modern steel industry.
READ MOREA tapping box protruding from the furnace shell is installed on the original tapping side to replace the original tapping groove. Refractory materials are built inside the tapping box, and a small molten pool is formed. It is connected with the large molten pool at the bottom of the original furnace and has a smooth transition. The tapping hole is opened vertically at the bottom of the small molten pool of the tapping box.
READ MOREElectric furnace equipment is usually a complete set, including electric furnace body, power equipment (electric furnace transformer, rectifier, frequency converter, etc.), switches, auxiliary auxiliary appliances (resistors, compensation capacitors, etc.), vacuum equipment, detection and control instruments (electrician Instrumentation, thermal instrumentation, etc.)
READ MOREElectric arc furnace is an electric furnace for smelting ore and metal at high temperature produced by electrode arc, which is suitable for smelting high-quality alloy steel. With the increase of service time of electric arc furnace, a small number of vulnerable parts need to be replaced at any time, mainly including copper electrode, copper wire mesh, quartz tube, etc. So, how should these parts be replaced?
READ MOREEBT electric furnace can retain 10% ~ 15% steel and more than 95% slag through eccentric bottom tapping. EBT electric furnace realizes slag free tapping by leaving 10% ~ 15% steel, maintaining sufficient molten steel in the tapping box and rapid back tilting (3 °/s) of the furnace body during tapping and tilting.
READ MOREWhat are the problems in the development of industrial electric arc furnaces in my country?? Analysis of the status quo of industrial development in my country. Industrial electric arc furnaces are a kind of energy conversion equipment. The input energy is in the form of chemical energy in fuel, electric energy, and heat energy of high-temperature flue gas.
READ MOREThe poor kinetic conditions of the metallurgical reaction in the molten pool have always been a technical problem in electric arc furnace steelmaking. The lack of agitation strength of the electric arc furnace steelmaking bath has a lot to do with the characteristics of the furnace type. The traditional electric arc furnace uses scrap steel as the basic raw material, mainly uses electricity, and is supplemented by chemical energy to produce qualified molten steel.
