Visits 1930s
| A Visit to Scunthorpe May 8th 1934 | |
| The photo shows Mr. Storer. On Tuesday, the 8th. of May, a party consisting of Mr. and Mrs. Storer, Mr. Shiells and eight members of the Science Sixth paid a visit to the Frodingham Iron Works, and the Appleby Steelplate works, near Scunthorpe. We travelled by car, arriving at Scunthorpe at 10. 30 a.m. Here we much regretted to hear that Mr. Westwood, who had arranged the visit, was ill and unable to conduct us round the mines. However, his chauffeur led us to the mines, where someone else was to meet us and show us round. At the mines however, all enquiries for our guides proved unsuccessful, and finally Mr. Storer and Heywood took the cars round to the offices at the other end of the mines, about 2 miles away, to try and find the missing guide. The rest of us filled in time by watching a huge steel shovel at work, scooping up 5 cwts of ironstone at a time, and swinging round and emptying its contents into waiting trucks with uncanny accuracy. After about twenty minutes Mr. Storer returned with the guides, and the visit officially began. In reality the mines were only quarries. The surface layer consisting of about 10 feet of sand which was dredged away and thrown to the waste side or loaded into trucks and sold for building purposes. The dredger removing the waste sand was considered to be the mechanical marvel of the visit. It slowly moved along the sandbank scraping up the sand in buckets, then the sand was thrown on to an escalator band moving at a terrific rate, which conveyed it 140 feet across the quarry on to the waste heap. The machine contained 3 separate units, one to provide power and move it along the bank, another to work the bucket dredger and yet a third to turn the belt. Most of us walked along a footbridge along side the conveyer belt, and experienced the thrill of being suspended 150 feet in mid-air above the ground level. Beneath the sand was a layer, 35 to 40 feet thick, of ironstone, containing about 23% of iron. Holes were drilled 20 feet deep by pneumatic drills into the ironstone layer. The holes were charged with explosive and detonated with an electric battery, breaking up the rock to be dealt with by the steam shovel. We were fortunate to come across a section almost ready for blasting and after a short wait everyone took shelter whilst Mrs. Storer impressively pushed down the plunger and was rewarded, after the second attempt, with a loud "woof", as the whole earth shook and tons of ore changed from solid rock to small pieces. After this several of us had a really good shaking, as we demonstrated to the workmen how not to use a pneumatic drill which was worked by compressed air at a pressure of 85 to 90 lbs. per square inch. Further down the mine a few specimens of peat were taken from a storehouse. The peat was cut from the surface layer at that point in rectangular pieces, put on racks to dry, and, as it dried it shrank to about a quarter of its original size. The peat was then used to drive a small engine. At last we emerged at the other end of the mines, quite dirty, and eager for dinner. But alas, there were still the pump houses to look round. First a modern building containing two air compressors supplying air for the drills at a pressure of 100 lbs. per sq. inch, the pressure being sufficient to work the drills half an hour after the compressor had stopped working. The compressors worked at a voltage of 2,500 volts and took 15 amps. Next we visited several disused pump houses. They were filled with big steam engines once used to pump away water drained out of the mines. These had been replaced by a comparatively small electric pump which cleanly and efficiently dealt with the water. Then we had to walk a distance of about half a mile, but being weak with hunger, it seemed at least five miles to the offices. At last, at about 1.30, we said goodbye to the guides, who presented us with some enormous fossils in addition to the ones we had picked up as we came through the mines, and expressed a wish to see us, or at any rate, a similar party from School, again. We then jumped into the cars and left for Scunthorpe, being told to make a hasty dinner as we were due back at the Appleby Works at 2.15. Before we leave the mines, here are a few facts. The mines consisted of two wings, the one traversed being two miles long. About 1.5 million tons of ore are dealt with a year, this being sold to the neighbouring iron-works to be smelted. 30 miles of railway track and 14 engines are used by the mines but the whole concern is owned by the Winns, who are known locally as the owners of Nostell Priory.

After an enquiry by a German as to whom we wanted to see, we were provided with a Scottish guide to take us round to see these British works. We were considerably impressed with the size of the buildings and the loud rumble of machinery busily at work. On the 2nd. floor of one of these girded buildings we saw two open hearth furnaces, each of 250 tons capacity. Here pig-iron, from the blast furnaces is fed in along with scrap iron, limestone and coke, and mild steel is formed. The molten steel is cast into iron moulds called ingots and these are taken to a second building where rolling is done; heating is done by producer gas at 1,100 degrees C. We saw the basic slag, which is formed above the steel, being run off in a molten stream into trucks. It gives such an intense blue-white glare that the workmen have to wear blue spectacles. This slag is tipped molten on to the slag heaps where it remains a dull red for several seconds. The ingots are stripped by grab cranes and re-heated to regain an even temperature. They are then rolled to a thickness of 4 ins, and cut by a sheering machine into slabs a yard square. The rolling mills are electric and operated from a cabin by levers. The slabs are re-heated and taken by swing cranes to another lot of rolling mills where they can be rolled in varying thicknesses. Electro-magnets are used for lifting the plates to cutting and planing machines. Here they are cut to the required size and the waste is sent back to the furnaces. The surface of plates is sometimes polished up by emery wheels used in a similar machine to a lawn mower. One of the latest electric planing machines we saw could plane all four sides at once. The last process is cleaning the sheets. This is done by a first washing in sulphuric acid and then two in water. The plates are then dried and sprayed with oil and stacked ready for sale. We also visited the testing houses, where the tensile strength and the breaking point of specimens of steel are measured. If these specimens do not conform to a fixed standard the steel has to be re-melted. We spent a very edifying yet Interesting afternoon, and our thanks are due to Mr. and Mrs. Storer and Mr. Shiells for so kindly organising the day for us. L. J.
