1. Project name: 20t / h natural gas single heat storage continuous heating furnace 2. contents of a project: Design and build a single heat storage continuous rolling natural gas with an hourly output of 20t / h Design and manufacture of furnace body, furnace body foundation, furnace body steel frame and furnace bottom slide rail. Design and manufacture of fuel gas system, air supply system, control system and smoke exhaust system. Cooperate with Party A for commissioning and acceptance after the system is completed. 3. Standard for design: Emission Standard of Air Pollutants in Industrial Furnace Kiln (GB9078-1996) General Provisions of Code for Construction and Acceptance of Installation Works of Metallurgical Machinery Equipment (YBJ201-83) Standard for Quality Inspection and Evaluation of Metallurgical and Electrical Equipment Installation Engineering (YB9239-92) Acceptance Code for Steel Structure Construction (GB50205-2003) Technical Specification for Coating of SteeStructure Pipe (YB / T9256-96) Code for Construction and Acceptance of Industrial Furnace Masonry Engineering (GB50211-2004) Other relevant standards. 4. technical requirement: 1. Engineering use: billet heating before continuous rolling 2, furnace type: three heating, three control control 3. Size of steel billet: 130 * 130 * 4000mm 4. Maximum workpiece weight: 0.53t 5. Heating temperature of the workpiece: 1150-1200ºC 6, maximum production: 20t / h (hot billet) 7, feeding mode:, the furnace tail push steel machine push steel 8, material: general steel, low alloy steel, etc 9. Feed-out method: side steel outlet 10, temperature difference requirements: uniform 11. Fuel type: natural gas 5. implementation plans: 1. System process design: The system adopts the continuous heating system of continuous heating, the furnace bottom of the furnace adopts the solid furnace bottom, the furnace tail pushes the steel furnace side out of the steel machine. Fuel requirements are for natural gas. The system is divided into six parts: heating system, combustion system, air supply system, smoke exhaust system, temperature control system, preheating system these six systems constitute an organic whole. 2. Heating system design part: 1) Furnace size: the effective size of the furnace is determined according to the size and production quantity of the workpiece. The total length of the furnace body is about 16315mm, and the effective length of the furnace body is 15m. Effective width: 4.5m, construction according to the actual design drawings. 2) Structure form: solid furnace bottom heat resistance slide rail heating, three sections of heating, three sections of control structure form. The steel outlet mode is the steel outlet at the furnace side, and the choke wall is set between the heating section and the preheating section to effectively control the pressure and temperature of the furnace in different sections. Reduce the height of the furnace in the preheating section to enhance the heat transfer of the furnace gas to the billet. Heating 22 points. The upper heating is 10 points on both sides of the furnace wall; 2 points on the furnace end wall; 3) furnace top structure: hanging flat furnace top, furnace top with high temperature and low cement refractory castable, thickness of 230mm, 100mm aluminum silicate fiber felt cover insulation. The hanging mechanism is composed of high aluminum hanging brick, hook, seamless steel pipe, I-steel beam is 28 #. 4) Furnace wall structure: the furnace wall uses low cement castable as the working face thickness of 300mm; the insulation layer uses light insulation brick thickness of 230mm, backing 100mm thick aluminum silicate fiber felt, using 5mm thick steel plate welded structure as the furnace shell.trough.
