The suspension of operations astatine the accident-site of the Continuous Casting Machine (CCM) successful the Steel Melting Shop-1 (SMS-1) of the Rashtriya Ispat Nigam Limited (RINL) Visakhapatnam Steel Plant is estimated to origin a nonstop accumulation gross nonaccomplishment of astir ₹4 crore per day.
The detonation of a ladle connected Monday evening severely damaged Caster-1 (Machine 1) of SMS-1, forcing an indefinite halt to operations. The Visakhapatnam Steel Plant operates with 2 Steel Melting Shops SMS-1 and SMS-2. Together, they location 10-12 high-capacity continuous casting machines—comprising six machines successful each SMS unit—across the alloy melting bays to solidify liquid crude alloy into intermediate shapes similar billets and blooms.
Sources astatine the VSP told The Hindu on Tuesday that connected average, a azygous continuous casting instrumentality astatine the works processes astir 750 tonnes of liquid alloy regular nether optimal turnaround cycles. With the existent marketplace worth of finished commercial-grade alloy hovering astir ₹50,000 per tonne, the abrupt paralysis of this superior casting enactment means a regular shortage of 750 tonnes successful formed alloy output, straight translating to the multi-crore gross drain.
“The calamity is estimated to origin a nonstop accumulation gross nonaccomplishment of astir ₹3.75 crore to ₹4 crore per day, and it whitethorn instrumentality respective days to resume operations astatine the continuous casting machine,” a root said.
“Interestingly, a insignificant occurrence mishap had occurred astatine the SMS-2 casting portion yesterday arsenic well, astir an hr earlier the large blast successful SMS-1, but it did not travel to airy arsenic determination were nary casualties oregon large damage. However, the SMS-1 incidental remains a large catastrophe and is the archetypal specified horrific calamity astatine the SMS successful the past of the alloy plant,” a reliable root successful the works told The Hindu on information of anonimity.
The suspension of operations compounds the terrible structural and fiscal challenges already being faced by the PSU. Beyond the contiguous nonaccomplishment of superior alloy volumes, the works absorption volition incur monolithic compounding fiscal damage. Superheated crude alloy accumulation cannot beryllium abruptly halted crossed preceding operational stages; immoderate disruption astatine the casting extremity forces upstream blast furnaces and basal oxygen converters to drastically throttle their liquid robust output oregon vent thermal energy.
Furthermore, clearing the extended debris of charred overhead infrastructure and cleaning the hundreds of tonnes of superheated molten metallic that spilled onto the store level astatine 1,600° Celsius volition necessitate a prolonged shutdown. Technical teams enactment that cold-setting alloy adhering to mechanical actuators, ladle descent gates, and electrical cabling volition necessitate tedious carnal cutting and broad re-installation earlier immoderate proceedings runs tin begin.
The three-member outer adept committee, which arrived successful the metropolis connected Tuesday greeting to probe the information and method breaches that led to the blast, is besides evaluating the grade of mechanical harm to Caster-2. Plant engineers fearfulness that if structural alignment issues are detected successful the machine’s instauration owed to the utmost thermal daze of the spill, the restoration timeline could widen implicit respective weeks, inflating the cumulative fiscal losses into tens of crores of rupees.
