Horizontal 80 Rod Copper Continuous Casting Machine 200Kw Holding Furnace 1. technical parameters 1.1 main technical parameters 1.1.1 casting type: two strands 1.1.2 casting specification: 10~80 1.1.3 raw material: red copper 1.1.4 casting speed: pulling speed: 0~43mm/s (stepless to adjust) pushing speed: 0~43mm/s (stepless to adjust) 1.1.5 power Melting furnace: 550KW Holding furnace: 200kw Tractor: 7.5kw 1.1.6 production capacity: 500tons per month(calculate as the DIA80mm specification) 1.1.7 noise: 80db 1.18 land: 8m(width)*20m(length) 1.2 installation level # The equipment has complete functions, performance parameters reasonable, the whole line can be controlled automatically . # The system adopt AC servo control system from japan, SIEMENS PLC from germany, maintained conveniently, reliable performance, the technics can be widely used. # The control system, electric elements, buttons, indicator light are all original binding products from well-known factories. # Adopt PLC programmable control. # The technological process parameters can be preset. 1.3 technical instruction This continuous casting line includes melting furnace, holding furnace, crystallizer, tractor, saw, electric control system, hydraulic control system and cooling system. 1.3.1 furnace The 550kw power frequency induction melting furnace and The holding furnace of 200KW power frequency induction furnace with the same body,there is a refined furnace chamber between the melting furnace chamber and holding furnace chamber,it is composed by upper furnace body, inductor, bracket, hydraulic system. The furnace shell of upper furnace body is welded with Q235A steel plate. The bottom have flange connected with inductor assembly. There are hydrocylinder and bearing pedestal at the two sides can tilt furnace 45. The indutor assembly is composed with shellbody, copper channel, iron core, loop, water jacket and refractory material. the loop is made of flat copper tube coated with double-fibreglass; the water jacket is made of stainless steel plate of 1Cr18Ni9Ti. 1.3.1.1 main parameters of melting furnace efficient capacity: 2.5t Total capacity: 3t Rated power: 550KW Rated voltage: 380V Consumption of cooling water: 5m/h(move in cycle) 1.3.2.1 holding furnace efficient capacity: 2t Total capacity: 3t Rated power: 200KW Rated voltage: 380V Consumption of cooling water: 3m/h(move in cycle) 1.3.3 Crystallizer The crystallizer is composed by framework, sealed filling frame, inner sleeve, outer sleeve, graphite die, seal components. Water cycle type is one entry one exit. Water pressure: 0.6~0.8Mpa 1.3.4 tractor 1.3.4.1 The tractor is composed by pedestal, electric machine, speed reducer, gapless gears, traction roller, screw down device. The pedestal is frame structure welded with Q235A steel plate, the electric machine choose AC servo motor from japan. 1.3.4.2 main parameters Power of motor: 7.5KW Rated rorate speed: 1500r/min Using rotate speed: 200~1200r/min Pulling and pushing speed: 043mm/s Shortest stop time: 0.01s 1.3.5 saw 1.3.5.1 The saw is composed by hydraulic system, saw noumenon, guide rail. The saw can move along the guide rail. After finsh the cutting, the saw will be pushed back by a oil cylinder. 1.3.5.2 main parameters Max sawing diameter: 100mm Cutting length :as the client requirement 1.3.6 Water cooling system 1.3.6.1 Main catalogs (1) cooling water flow: 40m/h (2) water pressure of the system: max0.6Mpa (3) water inlet temperature: MAX 30 (4) water outlet temperature: MAX 45 (5) hardness 150~180ppm 1.3.7 Electric control part of horizontal continuous casting line Electric control part divide into power frequency electric furnace AC control part and auomatic control part: # Power frequency electric furnace AC control part (1) Melting furnace adopt three-phases. Output working pressure is 90~380V, eight gears to regulating voltage, noload stepness automatic coupling voltage regulator(three phases balance). (2) Holding furnace use electromagnetic induction voltage regulator, can make load and stepless voltage regulating, its easy to control furnace temperature. (3) the bottons and indictors are from shanghai, all the relay, switches are from famous factory. b. Automatic control part (1) Summation of the system This part include main control PLC, human-machine interface, transducer, actuator, drive element and appurtenances The horizontal continuous casting line use a SIEMENS PLC as the main controller, all of the transducer datas are access this PLC and all the actuators are controlled by the PLC. The datas after treatment by the PLC will be transferred to actuator and the actuator control the sets running. Through exchange datas between human-machine interface and PLC, all of the running state and running parameters can be adjusted. This system has the following characteristic:
