Hot Rolling

After the over-whelming, response of customers for crown wheels and rings made thru the rolling process on the ACDR line, a new forging line called the HOT ROLLING LINE has been commissioned in March, 2009.

The hot rolling line consists of an induction heater, a 2000 Ton Blanking Hydraulic Press of Schuler make, and a fully automatic ring rolling machine. This latest and ‘State-of-the-Art’ transfer line consists of 2 ultra modern robots for bringing the heated parts into the press, forging within the press, and then for placing the blanks on a conveyor for onward rolling. The entire dimensional controls are fully CNC controlled to get an amazing degree of repeatability, and process stability.

The fully automatic forging process does not rely on manual labor at all, and can make crown wheels and rolled rings between 18 to 25 seconds for each piece. Some of the advantages of forging on this hot rolling line, over the conventional forging hammers, and presses are :

Advantages of Hot Rolling

• Material Saving
• Excellent surface quality
• Near-net close tolerances and less machining allowances
• Superior grain flow so higher strength
• No draft angles, no flashes, no mismatch

Capabilities

• Max Weight :- 75 Kgs.
• Max OD :- 550mm
