METHOD OF MANUFACTURING IRON AND STEEL SHEETS.
Specification of Letters Patent.
Patented Aug. 25, 1914.
Application filed September 19, 1913. Serial No. 790,760.
To all whom it may concern Be it known that I, Eonnn'r T. BANFIELD,
a citizen of the United States of America,
residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania,-have invented certain new and useful Improvements in Methods of Manufacturing Iron and Steel Sheets, of *f' -1ichuthe following is a specification, referen -e being had therein to the accompanying drawing.
This invention relates to a method of manufacturing iron and steel sheets and has for its object to set up a method, in a manner' as hereinafter set forth, to obtain a greater tonnage per mill, with less cost, than the methods now in general vogue.
A further object of the invention is .to provide, in a manner as hereinafter set forth, a method of manufacturing iron and steel sheets, free from scale and pitmarks, under such conditions reducing the cost when pickling for galvanizing or stamping.
A further object of the invention is .to provide a method of manufacturing iron and steel sheets whereby the number of furnaces required during the method is less thanthe number of furnaces required in the methods now in general vogue, at the same time increasing the tonnage completed and furthermore obtaining a considerable sav ing in the consumption of fuel.
In the drawings :.Figure 1 is a diagram matical View of an apparatus capable of carrying the method into effect, and Fig. 2 is a like view of an apparatus capable of carrying a modified form of method into effect.
Referring to Fig. 1 of the drawing 3 denotes a pair of tracks upon which travel trucks 4 for transporting the sheet bars, cut the required length, to the pair furnace 5 in which the bars are heated. 6 denotes a roughing .mill which is adapted to operate upon the heated bars removed from the furnace'5 and the mill 6 is adapted to rough down and roll the heated bars to the required length so as to match up into packs in numbers'of two, three or four sheets to pack, depending upon the number of sheets desired in the pack. The matcher removes the bars from the roughing mill 6 and matches'them up to size, then takes the matched material to the single furnace 7, two of which' ar'e shown and the matched material is reheated in the furnace 7 and after heated to thenecessary degree is taken to the finishing mill 8, and given one or two passes and returned to the matchers, it is then opened up and doubled into a pack,-
and then hammered down by the steam hammer 9 and after being hammered itis transported to a furnace 10 for reheating. From the furnace 10, the reheated material, is taken to the finishing mill 8 and rolled to the required length orgage. When carrying out the method, rough down bars from the roughing mill will be heated, after which they will be subjected to the finishing mills. In this connection it willbe stated that some of the bars will be taken to one of the furnaces and then subjecte to one finishing mill, and the bars next acted on by the roughing mill be taken to the other furnace, and then will go to the other finishing mill, and this alternate manner of heating the bars operated on by the roughing mill will be carried on during the operation of the method, thus making a continuous operation, giving a more uniform heat and expansion to the rolls. The roughing mills and finishing mills will be provided with suitable water cooling devices and cold air blowers to control expansion of the rolls. In carrying out the method a breaking down mill 11 is employed and to which the material from the furnace is subjected to, prior to the subjecting of the material to the roughing mill 6. In some instances the breaking down mill can be dispensed with.
In Fig. 2 of the drawings 12 denotes tracks upon which travel truoks13 for transporting the bars to the pair furnace 14 and from the latter the heated material is taken to the breaking down mill 15-, then to the roughing mill 16 and from the roughing mill 16 after matching taken to-the re-heating furnace 17 and from there to the finishing mill 18, then opened up" and'double-d over into a pack and hammered down by the hammer 19, then taken to the furnace 20 for re-,,heating and returned to a finishing mill for completion.
In the methods herein set forth, the rough-' ing mill will be in operation at all times supplying sheets or packs for the finishing mills on each side, .a1ternating each heat to one or the other mill. The roughing mill will relieve the finishing mill of one quarter of its work, getting that one quarter more in a finished sheet, or that one quarter mo" in tonnage of each finishing mill by utilizing the roughing mill to do a portion material, then removing the material from of the work of the finishing mill. "lVliat I claim is the front of the finishing mill,- then dou-- bling and hammering down the drawn nial5 a A method oit manufacturing metal-11c iterlal, then heating the hammered down and '5 sheets eonsistin'g in first heating cold sheet bars, then subjecting the heated material to a roughing mill to roll the material to the desired length, then removing the rolled material from the front of the mill, then again 10 heating the material, then subjecting the heated material to a'finishing inill arranged at one side of the roughing mill to'draw said doubled 1naterial,.and then subjecting the heated material to the finishing mill.
In testimony whereof I aifix my signature in the presence of two Witnesses.
