Scrap metal for recyling. World War Two or just after 1940's
Opening introduction, "It is common knowledge that there is a world shortage of raw materials and that more and more steel is required to supply or needs. Every ton of steel scrap recovered from factory, farm, or home can be turned into a ton of brand new steel ready for further valuable service". This information superimposed over railway sidings. Interior of junction box with signal man. Exterior fast moving steam train going along tracks. Points changing. Signals changing. Train takes scrap metal to foundry to be re-recycled. Ground explodes. Old fashioned detonator with plunger. The search for iron ore continues, diggers load iron ore onto railway transports. Shots of Africa with high grade ore being excavated. Iron ore is loaded onto ships. Bad weather in Bay of Biscay affects ship which we see in rough waters. Transporters move the ore from the ships into trucks for conveyance to the steel works. Iron ore is fed into furnaces to make pig iron. It is scrap, which is in short supply due to loss of deliveries from overseas that means half the steel of the country has to be made from scrap metal. These shots superimposed over a collection of scrap. Most of the steel is produced by the open hearth method. Production scrap such as off cuts rejects and odd ends from the factories, is charged into a furnace. Scrap being placed in open hearth furnace. Excellent shot of steel being poured into ladles. Here we see brilliant flashes of light. From the ladles it is teemed into the ingot moulds. In rolling mills, white hot ingots are rolled into any dimension including huge girders, bars for railway lines, or plates for scrap building. We see the progress of the rolls as they are squeezed thinner and thinner, until once coated with tin it becomes tin plate. Launch of ship. Manufacture of razor blades. Hand forged table knife, going through process of manufacture. Close up of canteen of cutlery. Locomotive driving wheels. Manufacture of turbine engines for jet aircraft. Manufacture of ribs and framework of umbrellas. Young woman reads a book while on bed made of steel. Close up of steel springs of bed with young woman reading book. Light switch being turned on. Cut to interior of power station with dynamos generators and other equipment. Clock shows number of mega- watts being used. Electricity generating station, with close ups and medium sot of pylons. Woman or housewife fills kettle at sink. Reservoir, brief shot. Giant water pumps removing water from the Thames water is filtered. Pumps which send water through to domestic homes. Giant turbines. Old fashioned gas cooker being lit with paper taper. Gas storage towers. Gas taps being turned on. Light being switched on, kettle being filled, gas cooker being turned on. Woman pours milk from glass bottle into jug. Dairy cattle in pens, and being milked by steel tube. Milk is transferred by steel container trucks to the bottling farm. Milk is pasteurized before being bottled. Milk bottles are washed, sterilized and cleaned by machinery. Full milk bottles are taken off and placed in metal crated ready for delivery. Young housewife opens tin can and pours contents through a sieve into a saucepan. Manufacture of tin plate and canning of carrots in factory. Excellent footage of conveyor belt with women filling cans. Housewife throws used or empty tin can in small refuse bucket. Refuse truck from Merton and Morden in London is shown. Refuse is thrown onto a belt and passed under a drum with powerful magnets. Discarded tins attach themselves to the rolling drum. Valuable tin coating is recovered for further use. Bales of residue of crumpled steel goes onto steel works. Allotment with shed. In background twin towers of industrial plant are visible. Broken spade, fork and shovels without handles thrown away from allotment shed. Back garden with washing line. Farmhouse. Horse-drawn plough being directed by farmer through field. Tractor pulling multiple plough through field. Close up of caterpillar tractor. Parade of four tractors. Scrap heap with miscellaneous kinds of scrap. Old grain reaper which has fallen into disrepair. Reaper cut into pieces of suitable size before transportation to the furnace. At steel works metal crane loads the pieces into a skip. The scrap is transported into the arc furnace. Manufacture of tractors with conveyor belt. Finished tractor. Smithfield market show with dairy or beef cattle and sheep. Brand new tractors on display. Other mechanical farm equipment made of steel is on display. Farmers fill up hoppers with fertilizer which is mixed with seed and then put into the ground. Fertilizer is made from slag, the residue or impurities drawn from the open hearth furnace after the pure steel has been poured. Basic slag is taken away for cooling before being ground and bagged. Small train takes hot slag out of foundry and deposits it on hillside to cool. Old and obsolete gas holder is stripped of its steel. Construction of new gas holder with new steel girders. Trams make their way along the Thames Embankment. Trams are broken up and burnt off. Trams burn. After burning superstructure and heavy chassis are cut into pieces before being taken to the heavy furnace. Trolley bus. Old man with pony and cart, rag and bone man. Old man collects scrap. Sorting and grading of scrap metal. Hydraulic presses used to turn loose scrap into balls. Bulky objects are crushed flat to occupy less space. Railway wheels are cut up in bits. Specialist work done to enable transportation. Trains are loaded with scrap metal at Park Royal in North West London.
