螺纹钢连铸连轧生产线

Rebar continuous casting and rolling production line

原料：废钢

Raw material:steel scrap

1、采用4套5t中频炉将原料废钢融化成钢水，产量达到280t-300t/班。（中频炉规格1.02线圈，输入电压1000v；变压器3150v变1000v）

2、融化好的钢水通过钢水包运送至连铸机中包车，然后对钢水进行浇注，通过振动机构、拉矫机、导向辊、调整辊、液压剪等生产出70mm-120mm方坯，连铸机拉速在1.5-2.5m/min（连铸机规格6m弧一机一流）

3、拉好的钢坯通过输送辊道运送至430三辊开坯轧机前往返轧制7道次，（430轧机电机为交流800kw；轧机线速度3m/s）

4、轧件通过输送辊道运送至精轧机组8架进行连续轧制，轧制出合格的成品通过飞剪进行备尺上步进冷床，轧件经步进冷床冷却后成组进行定尺剪切，定尺好的轧件再通过打包移钢进行人工打包入库。精轧K1线速度10-12m/s。（精轧机组300轧机6架、280轧机2架，电机分别为交流450kw一台，交流400kw一台，直流500kw一台，直流630kw一台）

5、成品φ12-φ18螺纹钢，φ10-φ18圆钢；轧钢生产线产能320t/班

Rebar continuous casting and rolling production line

Raw material:steel scrap

1. Using 4 sets of 5t intermediate frequency furnace to melt the raw material scrap into molten steel, the output reaches 280t-300t/shift. (Intermediate frequency furnace specification 1.02 coil, input voltage 1000v; transformer 3150v becomes 1000v)

2. The molten steel is transported to the continuous casting machine by the ladle, and then the molten steel is poured. The 70mm-120mm billet is produced through the vibration mechanism, the tension leveler, the guide roller, the adjusting roller and the hydraulic shear. The machine pull speed is 1.5-2.5m/min (the continuous casting machine specifications 6m arc one machine first-class)

3. The drawn steel billet is transported to the 430 three-roller billet rolling mill for 7 times by the conveying roller. (The 430 rolling mill motor is AC 800kw; the rolling mill linear speed is 3m/s)

4. The rolled parts are transported to the finishing mill by the conveying roller to 8 consecutive rolling, and the qualified finished products are rolled out to pass the flying shears to the stepping cooling bed on the preparation scale. The rolled parts are cooled by the stepping cooling bed and then grouped. The cut piece is cut to length, and the rolled piece is fixed and packed into the warehouse by packing and moving steel. Finished K1 line speed 10-12m / s. (6 sets of finishing mill 300 rolling mills, 2 280 rolling mills, one motor is 450kw, one AC 400kw, one DC 500kw, one DC 630kw)

5, finished φ12-φ18 rebar, φ10-φ18 round steel; rolling steel production capacity 320t/class
