Ladle Of Steel

In 1864, over 700 acres (280 ha) along the banks of the River Tees.

The Teesside Steelworks was a large steelworks that formed a continuous stretch along the south bank of the River Tees from the towns of Middlesbrough to Redcar in North Yorkshire, England.

At its height there were 91 blast furnaces within a 10-mile radius of the area By the early 1990s, when No.4 furnace at Cleveland Iron closed there was only one left on Teesside. Opened in 1979 and located near the mouth of the River Tees, the Redcar blast furnace was the second largest in Europe.

The amount of slag coming out of the various furnaces of Teesside increased substantially and its disposal became a costly problem for works' owners. One solution, invented in the 1870s, was the Scoria brick which became a major export of the region and can still widely be seen as a road surface in the local area.

On 1 October 2022, the Basic Oxygen Steelmaking (BOS) Plant at Lackenby was demolished in one of the largest single explosive demolition operations in the country in 75 years.

From some minutes I found, the idea was to create a series of entrance features for the South Tees Industrial Estate that celebrated 150 years of industry in South Bank. I will say the artist chose the colours for the ladle and metal, but I also found this on the lighting engineer's website.

Each feature was designed to reflect the industrial heritage of the area with the steel making industry being the focus of this installation. The feature itself depicts a steel ladle pouring steel into a mould, the ladle itself is a genuine ladle recovered from a local foundry. With clever use of the steelwork depicting the poured steel the sculpture appears to float in the air. The lighting brings the sculpture to life at night. With the highly innovative use of LED on the scheme this allows at the onset of night a floating sensation of the ladle and it is fair to say the artwork is best viewed at nightfall. The scheme also included the illumination of the gateway walls. The lighting scheme was commended as part of the Redcar and Cleveland Design Awards.

'The project was a competition, and one of my submissions was a ladle idea. The project, like many of my works, was fabricated locally. The pouring was designed to have some dynamism and, hopefully, prevent climbing in. That turned out not to be the case! so a mesh was installed. The colours were chosen so that, with internal and external lighting, it would look hot at night. When I last saw it, it seemed to need a lot of TLC! Here are some pictures.

The ladle sculpture is the first part of the process whereby the liquid iron is 'tapped' from the blast furnace and transported to the converter where it is treated with oxygen to burn off the carbon and remove Sulphur and Phosphorus. The carbon is oxidised into CO & CO2 and is lowered from around 4.30% to almost zero. The Argon & Nitrogen inlets are for stirring and are used as they are inert gases. The liquid which is now almost pure iron is transferred to the degassing station where it is stirred with Nitrogen and/or Argon. The vacuum chamber allows oxide impurities to float out of the liquid metal. At this point additions of carbon, Silicon and Manganese are made to produce plain carbon steel. It is then transferred to the bottom pour ladle to be used in the continuous casting process.' 'The artist has used a bit of his licence on this, as steel is normally poured out of the bottom of the ladle. There is one stage where it's poured into a Bessemer converter to blast it with oxygen which uses this type of ladle.

'During the Arc furnace melting process limestone is constantly added to the furnace which reacts with the liquid steel this absorbs Phosphorus and Sulphur. Following the Carbon boil the slag is further enriched with Iron, Carbon, Silicon, Manganese, Phosphorus and Sulphur. The slag is very fluid at this stage and is very light compared to the steel so it floats on the top, the furnace is able to tilt in two directions, forward to empty into the ladle and backwards to run off the slag which easily pours from the furnace into a metal mould for collection and disposal. Uses: Arc furnace slags are alkaline and around 50% Calcium and Magnesium Oxides. It can be used as a soil improver supplying trace elements and a pH stabiliser. It can also be used as an aggregate for road building materials.' 'I can only make an approximation on the ladle size from the people in the photograph but I would estimate it would hold around 40 tonnes which is sufficient for 45 Ford Pumas.'
