Brazilian steelmaker Companhia Siderurgica Nacional (CSN) quickly resumed steel production on Wednesday following an incident at a slag converter located at its Presidente Prudente mill in Volta Redonda, Rio de Janeiro state, the company told SteelOrbis on Thursday.
The company said there was a failure in the process of converting pig iron into steel. The company's converter A was humid when liquid slag was poured into it, causing a cloud of smoke. Steel production was halted for a few hours but was then resumed, the company said.
A local union said the incident affected 25 workers. CSN said all workers are well and no casualties or injuries were reported.
The company’s Presidente Prudente mill, located in Volta Redonda, Rio de Janeiro state, has a 5.8 million mt/year capacity.
