Who/What is a BF? - Sepia Saturday

In these days of social media and texting you have to be careful interpreting abbreviations.

This week's image from Australia quickly reminded me of what BF once meant to me.



My first job in industry was at the Redbourn works of Richard Thomas & Baldwins integrated iron and steel plant in Scunthorpe, Lincolnshire. 

As a graduate trainee I was expected to spend time on projects in each of the different departments. The first of these, in the Blast Furnace Departmet was to prepare trial mixes for the sinter plant that was being constructed. Sinter was to be used as input to the company's blast furnaces to improve their performance.

Iron ore,coke and limestone batches were mixed by hand (shovel) and subjected to heat using a gas-fired box. The resulting sinter was then subjected to a shatter test to determine which mix would stand up best to loads encountered in the blast furnaces themselves.

You could say that my small group often thought they were BFs while carrying out this work for the BF Department. 

The prompt photo of the Newcastle Blast Furnace Department doesn't actually show a furnace. It's difficult to make them out in this also.

The tops of the furnaces may be seen in the top left centre of the image to the right of what looks like three cylindrical vessels.

Redbourn blast furnaces - 1979
A hundred years of ironmaking at Redbourn ended in October 1979 when  the No 2 blast furnace made its last batch of 194.8 tonnes, watched by former production men, engineers and managers from other areas of the Scunthorpe works complex, chiefly Appleby- Frodingham and Normanby Park.

The furnace was built in 1951/2 to replace two hand-charged ones which had stood on the site since 1875.
Two sister furnaces had already closed. No 4, built in 1919, made its last iron in 1977; while No 3, dating from 1909, finished in September 1979.

The British Steel closure of Redbourn blast furnaces  was part of a rationalisation plan which included capital investment in the much larger Queen Victoria and Queen Anne furnaces, blown in by the Appleby-Frodingham company in 1954.

These days if I wish to see a blast furnace I don't have far to go to see the one at Redcar near our North-East home.

I left Redbourn in 1969 so never saw the demise of the works.
Finally I have dug out a video on Scunthorpe's Iron and Steel Heritage that shows scenes from the three steel works that existed while I worked there.

Hope you enjoy it as much as I did.

Sepia Saturday Silos

If you have a minute or two to spare I'm going on a silo tour starting with missiles at Edwards Air Force Base:

In England I had a pick of thousands of silos from farms across the country before settling on these with a brickwork base. They look older that those in made of concrete or steel.

In Germany I discovered a factory at Erfurt which makes feed for cattle, pigs and chickens. The picture dates from 1977 when they made 2000 tons more of the stuff than in 1976.

My first project as a graduate trainee in the steel industry in the UK was to make up trial sinter mixes for the blast furnaces at Redbourne Works in Scunthorpe. We did it the hard way with a shovel!

When I found this picture  of the charging hoppers (silos de chargement) for a blast furnace in France it just had to be included.

How many of you remember the Gregorian Chant sung in by monks from the monastery of Santa Domingo de Silos. They made the UK charts in the 1990s. The monastery is located in Northern Spain. 

I could have picked many images from there but settled for one from their laboratories, If you use your imagination you can scale up the vessels to 'silo' size and anyway it's the nearest I could get to a sepia colour.


Finally to Norway where I worked on the early stages of the project to build the Troll A gas platform. 

(My photo)

This tilting concrete tower in Jåttåvågen is 60m tall  at Hinna,  in Stavanger. The tower which is tilting 16 degrees towards the ocean was originally built in 1984 for experimental tests before they started on the Troll-Platforms in the later 1980s and 1990s.

Troll-A Platform at 472m tall, was the tallest and heaviest construction ever moved by man). The legs of the platform go down over 300 metres; 100 meters at the bottom are tilted like the tower in the previous picture.

You will find more silos at Sepia Saturday
