Wrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure.
Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace. Cast iron can be made directly from the molten pig iron or by re-melting pig iron, [4] often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking various steps to remove undesirable contaminants.
In 1936, the contribution to UK steel production from the north east was 27.3%, but by this time much of the ore was being imported. [19] Apart from a dip in 1922, the smelters on Teesside first started using a greater proportion of imported ore over that mined locally in 1936. [20] Iron ore usage on South Teesside 1913 – 1936, expressed in ...
Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. [ 1 ] It is the most common cast iron and the most widely used cast material based on weight.
The Loftus Iron Company was established c. 1873/74 at Skinningrove on the north east coast of England between Redcar and Whitby. Initially two blast furnaces were built, approximately 1 mile from ironstone workings. [1] [2] In 1877, the business was liquidated, and was acquired by the Skinningrove Iron Company in 1880. [3]
The Iron Bridge is a cast iron arch bridge that crosses the River Severn in Shropshire, England. Opened in 1781, it was the first major bridge in the world to be made of cast iron . Its success inspired the widespread use of cast iron as a structural material, and today the bridge is celebrated as a symbol of the Industrial Revolution .
