Stopper rod mechanism is an integral part of the stopper rod which controls the metal flow from tundish to the mold. The stopper rod mechanism consists of a stopper rod which is connected by an arm to the lever rod. Stopper rods consist of a stopper rod body and a stopper rod tip at a lower end of the stopper rod body

JSW Infrastructure Ltd, the port operating unit of Sajjan Jindal-led JSW Group, commissioned a 370-metre long terminal, with a capacity to handle 18 million tonne per annum. The Group has invested Rs 750 crore to build an iron ore terminal at the Paradip port in Odisha. JSW commissioned its new terminal at Paradip by loading approximately 60,000 metric tonnes of iron ore pellets on the bulk carrier MV IC Phoenix for one of the country’s leading pellet manufacturer, Brahmani River Pellets Ltd.

Public sector steel major, SAIL is looking at 100 per cent stake sale in Salem Steel Plant (SSP) and is looking for a potential buyer.The Salem unit had already been modernized and expanded at an investment of Rs. 2,371 crore to produce 180,000 tonnes per annum of stainless steel slabs.It has added a steel melting shop, a single strand slab caster and roll grinder for hot rolling mill, and a cold rolling mill complex, which was a part of its expansion programme

The ladle lip ring holds the wall (barrel and slagline) tight in compression throughout the ladle campaign and withstand the steel/slag dumping process and associated cleanup of the ladle lip.

The mining leases of 329 private mines is going to expire on March 31, which includes 48 operative(24 in Odisha, six each in Jharkhand and Karnataka, five in Gujarat, three in Andhra Pradesh, two in Rajasthan, and one mine each in Himachal Pradesh and Madhya Pradesh) and 281 non-operative(184 non-operative mines in Goa, 42 in Karnataka, 12 each in Jharkhand and Madhya Pradesh,9 in Maharashtra, 7in Odisha, 6 each in Andhra Pradesh and Gujarat, 2 in Rajasthan, 1 in Himachal Pradesh) mines

Carbon percentage is kept high to impart slag resistance properties(10-20%C). It consists of more than 50% fused MgO grains of the highest quality

Ladle working lining should remain inert to the steel apart from rendering special functions like prevention of breakouts, containment of heat etc.

Thermal cycling is of huge concern. The pre-heat of the lining is somewhat important as far as thermal cycling is concerned. The lining suffers from temperature loss when the ladle goes for slide gate inspection after slag dumping. If the activities in ladle slide gate plate inspection/ replacement involve too many activities the temperature drop is even higher

The major factor responsible for the crack formation is the impact due to the tapping stream which forces the slag sitting on the bottom to penetrate deep inside.

Ladle safety lining is very important as far as the prevention of ladle breakouts is concerned and at the same time, it helps in the retention of heat and protects the shell from cracking.
