The temperature shoots up and the carbon also begins to burn soon the oxygen in the air combining with the carbon in the metal forms carbon monoxide the result is a fierce flame burning up the mouth of the converter a warning signal to the blower now is the critical period when the flame turns white Metal Corner Brackets every eye is concentrated on the flame or the moment to end the blow when the carbon is finally burnt out must be judged exactly the fury of the blow is spent the molten metal inside has become almost pure I’ve to make it into steel a controlled quantity of federal manganese is added first next an alloy of iron and manganese old Spiegel is audited this increases the carbon content and turns the molten iron into the steel of the right analysis while the molten metal is being poured further addition ferrosilicon is charged to the teeming life man still controls the flow of metal now he must give it a solid practical shape one.

In which it can be wet in the rolling mill that solid shape is obtained by teaming steel into English you can see here the result and importance of movement control as the modes of field a second converter is already being burped Terron moves from the previous teaming are being stripped these go to what are known as soaking bits which already contain ingots stripped earlier soaking means exactly what it says the ingots are literally soaked with heat for about two hours reaching a temperature of 1200 degrees centigrade before they are ready and malleable enough for the rolling mill brilliant flame of the converter lighting up the Bessemer shop is the very spirit of the works always ready to draw our eyes and our breath the ingot will become a steel rail and the Queensland aimed chariot takes it to the cogging mill for the first stage of its transformation every backward and forward roll and Outdoor Screws term will slowly shape these ingot into what steel men call a blue above the mill in the puppet men are still the calm and patient.
Masters of the metal with quiet concentration and perfect understanding they roll the steel to exact size and a bright strength and internal structure picking got the blue to be passed on for further rolling they call this the roughing mill the bloom would probably call it much the same with each pass the bloom becomes longer and thinner and soon it begins to take on the shape of a rail roughing being completed now over to the finishing mill men still take a hand in turning the rail but it has to be rolled sometimes on the flat more often on the edge even the rail the bleed it’s progressed wagging its tail as it passes through in cutting to rough length allowance is made for contraction during cooling it can control of the foot the rail is a cold 60-footer it has to be made perfectly straight.
