High Speed Mini Steel Hot Rolling Mill Machinery 80mm × 80mm Billets
HOT ROLL MILL PROCESS EQUIPMENT
Design basis
1. Raw material spec: 80×80×2000mm-200x200x2000mm 2. Final products spec: Φ10~Φ30mm hot-rolled deformed bar, cut-to-length 12m 3. Hourly output: 10t/h |
Rolling type and rolling mill configuration
Equipment characteristic
1. Rolling mill stand adopts pre-stressed type. This type is high stiffness and easy to change roller. 2. The rolling mill’s driving applies reducer and the duplex adopt two-grade reduction united gearbox. This type has following advantage: low weight, small volume, economical space occupation, low cost and etc. Gear-shaft material: 42CrMo forged, Wheel gear material ZG35CrMo, the box is of structural parts. 3. Cooling bed entering adopts free of roller table pneumatic entering type, which has the advantage of light equipment, simple, low cost and easy maintenance compared with apron plate type enteringdevice. 4. End-cropping and multiple-length flying shear adopt pneumatic clutch frequency controls speed, rotatory type. This type of flying shear has the advantage of low motor power, simple electric control and low investment compared with start-stop flying shear. 5. The bundling adopts mechanical pneumatic combined type automatic machine, and the material for bundling is Φ6.5mm wire rod. |
Process equipment introduction
Qualified cold billet lifted to charging roller table by crane to arrive at furnace end of reheating furnace, then to be pushed into reheating furnace for heating by billet pusher. When billet temperature reaches to 1150-1250℃, billet will be pushed out of furnace by billet-out device; via furnace out roller table and working roller table before rolling mill, billet will go into rough rolling mill, intermediate rolling mill and finish rolling mill step by step. The final products will go through remained heat treatment device and be cut by multiple-length flying shear and then arrive to cooling bed for cooling by cooling bed entering device after speed-up roller table. After cooling, by cooling bed exit device, the products will be transferred to run-out roller table, and then go to cut-to-length shear. After cut-to-length cutting and inspection, the final products will be transferred to final product span from final product cross span inspection bracket and then being collected, bundled, weighed, labeled and finally stored. |
