Acid steel

Client: rupertharris

Location: Glossary

Steel produced in a furnace with an acid lining i.e. consisting of a siliceous refractory and under a siliceous slag. With an acid slag, carbon, silicone and manganese only are removed so that the pig iron must not contain sulphur and phosphorus in percentages exceeding those permissible for the specification being made. Most steel today is manufactured in furnaces with basic linings.
