Product Description Water-Cooled Furnace Door Block EAF Copper Furnace Door Drum The furnace door water cooling block is a cooling device installed near the furnace door of the steelmaking electric arc furnace.It is used to cool the furnace door part under high temperature and high heat conditions to prevent overheating damage.This water cooling block usually adopts copper, copper-steel composite tubular structure, with multiple rows of winding steel water cooling pipes, and gap water cooling pipe sealing plates are provided between them to ensure cooling efficiency and water cooling effect.It is conducive to improving the impact resistance of the water cooling block, increasing the life of the electric arc furnace, reducing production costs, and is suitable for production requirements of energy saving and consumption reduction. Product Description FeaturesThe water-cooling furnace door block of the electric arc furnace and industrial electric furnace is a frame suspension structure, that is, the water-cooling furnace door block is fixed by connecting the top hanging and the bottom hanging with the water-cooling frame, which can be quickly installed, replaced and disassembled.After installation, connect the water inlet and return pipes, adjust the design pressure, and discharge the internal gas before putting it into use.There are pressure, flow and temperature measuring devices on each water-cooling block inlet and return branch, and the minimum flow, minimum pressure, maximum alarm temperature, etc. are set, which are interlocked through the PLC system and displayed on the monitor screen.The use of the furnace wall furnace door drum is monitored at any time to ensure its normal and safe use.The water-cooling pipe gap sealing plate of this structure is spot welded on the steel water-cooling pipe and the copper water-cooling pipe, which can effectively prevent a large number of sparks from flying out during use, avoiding safety hazards and reducing some heat loss.In addition, the place where the steel water-cooling pipe and the copper water-cooling pipe are connected is also welded by copper-steel composite welding process. Structure of Water Cooling Copper Furnace Door BlockThe copper-steel composite tube type and copper water cooling furnace door blocks structure used in steelmaking electric arc furnace are arranged on the furnace wall of electric arc furnace, including multiple rows of winding steel water cooling pipes, gap water cooling pipe sealing plates are arranged between steel water cooling pipes, and water cooling block inlet and return water inlet are arranged on one side of steel water cooling pipes.The ends of the steel water cooling pipes in the bottom row of the multiple rows of winding steel water cooling pipes are connected with copper water cooling pipes. The bottom hanging is welded to the bottom two ends of the water cooling furnace door drum.The specific position can be adjusted according to the actual use. The top hanging is fixed to the top two ends of the water cooling block and cooperates with the positioning pins of the furnace wall water cooling frame. The bottom hanging and the top hanging are mainly used to fix the water cooling block so that it can be safely installed on the furnace wall frame.Usually, the copper water cooling pipe is at least one row of winding. Product ParametersTechnical Requirements The welding groove between the copper pipe and the elbow (the elbow is chamfered according to the diagram) is shown in above drawing;Cover all gaps with steel plate;Unspecified fillet welds: 0.7 times the minimum thickness of the material;The welding between pipes and elbows must comply with the N-IS0-1708 standard ;Full penetration welding is required (acceptance criteria: D level in accordance with EN-IS0 5817);Test pressure 1.2MPa, Test time: 3 hours (continuous). Advantages of Water-cooling Copper Furnace Door Blocks> The comprehensive economic benefits of the furnace door water-cooling blocks produced and supplied by Sanrui electric furnace have also been greatly improved through analysis of actual on-site use.> It can reduce the hot downtime by 20% to 30%, improve production efficiency and production safety and reliability, and greatly reduce production costs and labor intensity of workers.> It can effectively prevent the occurrence of water-cooling block leakage due to local overheating.> It can increase the life of the electric arc furnace, reduce production costs, and meet the production requirements of energy saving and consumption reduction.> According to the actual design power, furnace shell diameter and number of water-cooling blocks of the steelmaking electric furnace, the water-cooling blocks with large heat load on the furnace wall and prone to accidents are analyzed, such as the water-cooling blocks close to the furnace wall oxygen gun, furnace door oxygen gun and electrode are the focus of consideration.> Combined with the actual production situation, the installation of copper or copper-steel composite water-cooling blocks with different rows in these key areas can effectively avoid the phenomenon of burning through and leakage due to local overheating, which brings unnecessary losses to production.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.
