End-Charge Steel Pusher Reheating Furnace with Side Ejector Discharge and 110t/H Capacity¹

Product Description Product Description1 Process Requirements and Basic Parameters1.1 Type of Reheating FurnaceA three-stage continuous pusher-type reheating furnace for billet heating, single row charging, end-in and side-out, vaporization cooling, and dual regenerative storage.1.2 Type of Reheating SteelOrdinary carbon structural steel,High-quality carbon steel,Low alloy steel..1.3 Billet SpecificationSpecification:180×420×6000mm1.4 Billet Input and Output TemperatureCharging Temperature: Above 700oC hot chargingDischarging Temperature:1050~1250oC1.5 Output of Reheating FurnaceReheating Capacity:110t/h (Above 700oC hot charging)1.6 FuelCategory: Blast Furnace GasCalorific Value:low calorific value750×4.18 KJ/m3Pressure: 8~10KPaContact Flow Rate: 27500Nm3/h(Above 700oC hot charging 110T/H,10% Factor of safety)Dust Content:  5mg/Nm3Water Content: 2mg/Nm32 Brief Description of the Process2.1 Brief Description of the ProcessThe continuous casting billet is clamped onto the billet charging platform by a crane clamp, or it is transported from the continuous casting outlet roller table to the furnace end charging roller table via the charging roller table. It is then pushed into the furnace by a hydraulic pusher and heated in the furnace to a temperature of 1050°C to 1250°C before being taken out. The heated continuous casting billet is sequentially discharged by the side steel removal machine and transported to the roughing mill unit through the discharge roller table for rolling.2.2 Layout of Reheating Furnace AreaA new pusher type reheating furnace is built in the reheating furnace area.The reheating furnace is equipped with combustion air blower, flue gas induced draft fan and coal smoke induced draft fan, which are located in the blower room and induced draft fan room respectively.The reheating furnace is equipped with two steel chimneys, one for gas side exhaust and the other for air side exhaust.The reheating furnace is equipped with a separate electrical room for housing the electrical cabinet of the furnace.The charging and discharging operations, instrument control, and electrical control of the reheating furnace are centralized in the main control room located on the furnace's discharging side.The gas connection platform of the reheating furnace is arranged outside the furnace area of the plant.The steam drum platform and pump room are arranged vertically on one side of the heating furnace.The hydraulic station for the pusher machine is set up separately and located near the side of the pusher machine.3 Reheating Furnace Process Plan3.1 Features of the Design Plan1) The reheating furnace adopts a dual regenerative combustion mode, with burners arranged on the side wall of the furnace. The furnace has a simple and compact structure, resulting in high thermal efficiency.2) The burners adopt the latest combustion concepts, offering smaller size, longer lifespan, lower energy consumption, and lesser combustion losses compared to previous models.3) The reversing valve adopts a next-generation product, with lower resistance loss, more reliable sealing, and easier replacement of vulnerable parts.4) The reheating furnace utilizes a three-stage furnace temperature automatic control and an improved dual-cross limit continuous control. This enables better furnace temperature control progression and responsiveness, effectively reducing combustion losses and conserving fuel.3.2 Main Dimensions and Structure of Reheating FurnaceEffective Length of Reheating Furnace ---------------  30000 mmInternal Width of Reheating Furnace ----- ------------  6700 mmHeight of the Upper Furnace Section in the Reheating Furnace ---------  1500 mmHeight of the Lower Furnace Section in the Reheating Furnace ---------  1900 mm3.3 Combustion System of Reheating FurnaceThe reheating furnace adopts the left and right combined burner, where air and gas are combined into one combustion unit.The burner consists of a heat storage tank and a nozzle. The heat storage tank is a steel shell lined with heat insulation material and casting material, and the heat storage body is placed inside. The nozzle is made of the refractory material of the furnace wall and is casted as a whole.Multi-layer sealing structure is adopted between the heat storage tank and the furnace wall. The nozzle and the furnace wall are integrated and fixed by the anchor brick of the furnace wall and the steel plate of the furnace skin, so as to eliminate the problem of gas stringing and fire leakage of the furnace wall.The interface between the heat storage chamber and the pipes takes into account the balance and deviation of air intake and exhaust flow. The burner nozzle considers issues such as the air mixing angle, velocity, primary and secondary mixing, as well as the deviation of exhaust flow.     Three-dimensional illustration of the shape of the regenerative burner                                               Burning in the furnace                                          Regenerative burner- In the field                                                                                Regenerative burner operating platform4 Automation System of Reheating FurnaceThe system includes the design, supply, and installation and commissioning of the instrumentation and automation of a pusher type reheating furnace body and evaporative cooling system. Automatic operation room(For reference)  Company ProfileCompany ProfileVisionWith decades of rapid development and accumulation, China has been perfect and mature on technology and management in various industrial areas, shaping a complete processing manufacturing industry with competitive price, well known for its excellent skill, high efficiency and hardworking team with qualification for personnel dispatching.At the time of economic globalization, it is our consistent target and objective to integrate and export all kinds of technology, management mode, engineering project and manpower as per the actual requirement of our client With our own abundant technical strength, superior integration capability of technology and resources, well experienced of project implementation and management as basis and platform;Let China go out to the world, and make the world know of China;ProfessionalProfessional technical and management team with abundant experience in the implementation of domestic and international projects;ResponsiveResponsively and meticulously, translating your needs into complete solutions;IntegrationIntegrating various technologies and resources in China and fulfilling complementary advantages, by relying on professional teams;MotivationMotivated to provide the optimal solution and quality products;ExceptionalExceptional, delivery and,implementation of projects to meet, your expectations;Our TeamProfessional technical teamPrime is staffed with a professional import & export team skilled in the practice of import and export business, including sea freight packing, logistics organization, L/C review, cargo booking, and customs clearance, L/C negotiation, double authentication of shipment documents, etc.All the above personnel is well experienced in the execution of projects in Southeast Asia and the Middle East.
