AUTOMATED HIGH SPEED ROLLING MILL

With the help of computerized process, qualified engineers of Kalliyath passes the 1,2000C billets to the special automated high-speed rolling mill. The process is controlled by monitoring devices, in an all mechanized technical operational environment. This enables the production of rebars with perfect shape, uniform thickness and equal standard length. The rolling mill operating in tandem with the continuous casting machine cools the billet temperature to help reduce the material and within 40 seconds, these billets are made into TMT bars ensuring excellent dimensional tolerance and surface finish.
Most of the rolling mills in Kerala have the manual process which takes too much time and lacks the temperature required for processing. This leads to the loss of quality of the TMT bar.

The process utilize residual heat from the rolling process to attain the desired mechanical properties. Billets, which are heated in the re-heating furnace, are rolled through a series of rolling stands and progressively reduced to the final desired size and shape. The most important factor in this stage is that the temperature of billet should be 1,2000C.

For reduction, billets are passed through the vast automated high-speed rolling mill units of Kalliyath. Normally, TMT bars needed for gauge are passed only 15 to 19 times. But at Kalliyath, bars are passed 21 to 25 times to ensure uniform size, shape and strength to decrease the production time. Mills that work with manual technology reduce the number of passes which results in the loss of quality, strength and unique shape of the TMT bars.
