Product Description EAF water cooled roof adopts the tubular water-cooled closed tube furnace cover structure.Product DescriptionFeatures:1. Increase the effective volume in the furnace and increase the output;2. Reduce loading times;3. It can improve the power level of the furnace;4. Reduce the number of furnace repair and improve the productivity;5. Long arc operation can be adopted to improve the power factor;6. Significantly reduce refractory consumption;7. It can recover the waste heat of cooling water and save energy;8. The return temperature of cooling water can be used as the control signal during production.Introduction To Water-cooled Furnace CoverThe electric arc furnace cover includes the furnace cover body and the receiving hopper device. The main structure frame is made into a circular shape with seamless steel pipes, which not only serves as the strength requirements of structural members, but also serves as the main inlet and return water pipelines. Each cooling water pipe is connected through the main inlet and return water pipelines.The rest is composed of slightly smaller dense tubes. The water-cooled plate is easy to replace and maintain, and its service life is>3000 boilers.Electric arc furnace (EAF) roof's water-cooled material pipe is adopted at the lower part of receiving hopper. Flanged stainless steel metal hoses (with swivel adapter) are adopted for the main inlet and outlet cooling pipes of the furnace cover, and handle-type stainless steel metal hoses are adopted for other water cooling pipes.The central part of the electric arc furnace (EAF) roof is a small central cover with three electrode holes, made of refractory castable.Product ParametersWater Cooled Roof Equipment PerformanceProduct TypeFan-shaped, roundSpecifications10-100 tons rangeMaterialsteelMaterial RequirementsHigh Temperature ResistanceThe material must have good high temperature resistance to withstand the high temperature inside the electric arc furnace.Corrosion ResistanceCorrosion-resistant materials should be selected to prevent the furnace cover from being corroded in an environment of high temperature and molten metal.Thermal ConductivityGood thermal conductivity can effectively dissipate heat and prevent the furnace cover from overheating.Strength & ToughnessThe material must have sufficient strength and toughness to withstand the mechanical pressure and impact during operation.Common materials include heat-resistant alloy steel and cast iron.Tube nest type EAF water-cooled furnace roof refers to that the water-cooled surface of the inner wall of the electric arc furnace cover is composed of closely arranged steel tubes with cooling water in the tubes. The tube type water cooled furnace cover is divided into integral type and combined type. Due to the large structure size, the combined water-cooled furnace cover is divided into 2~6 pieces for manufacturing in consideration of transportation and water distribution, and then combined into a whole.Generally, it is appropriate to adopt split assembly type for the cover with the diameter of 4.5m or above. Due to many openings and accessories on the cover, the water cooled furnace roof of the ladle furnace is mostly of integral type.When the cooling water enters the water-cooled furnace cover, the main water distribution pipe comes out from the main water distribution pipe and is divided into several branches to enter the water cooling plates. The cooling area and resistance of each branch are different.Notes: The above parameters are only part of the information and are for reference only.

Low power consumptionSR's large current system made of pure copper as conductive medium, the whole circuit with less resistance. Electrode arm shaped as copper-clad box type, resistance and heat can be reduced efficiently. Reasonable arrange of all conductive systems to minimize the resistance of every circuit.2. Safety & StabilityFull set of hydraulic driving system equipped with accumulator to ensure stability of facilities in the operation process. Whist, equipments can go on the motion when there any emergency accidents happen.3. Low electrode consumesElectrode breaks in the process of melting brings huge economic losses and inconvenience. SR's patented <anti-break of electrode system> technology dramatically drops the possibility of electrode cracks in the operation.4. High flexibility & Maximum simplicity of operationHMI used in electrical automation control, interface simulates the real form of furnace, which make the operation more convenient. Mixing feedstock, charging feedstock, melting, tapping all the commands can be implemented by computer.5.High arc forming efficiency SR's patented technology < Precision regulating electrode >, utilizing multi signal acquisition, PLC signal contrast technology,shortening the formation time of electrode arc,so that to avoid long time arc formation influence the upper grid system. Different with traditional single signal return control technique.6.Diversified dust removal systemSR's furnaces are equipped with a variety of dust removal systems, can be based on environmental requirements of different countries support different forms of dust removal equipments.
