IMPROVEMENT lNCONVERTER'S FOR., THE MANUFACTURE 0F BESSEMER STEEL.
Specification forming part of, Letters Patent No. 115,279, dated May 30,1871.
To all whom `'it may concern: l y
Be it known that LHENRY CHISHOLM, of
Cleveland, in the county of Cuyahoga and i State of Ohio, have invented certain new and f useful Improvements in Steel-Converting Vessels, of which the following is a description, reference being had to the accompanying draw- Figure l is a side view of the convertingvessel.V Fig. 2 is a vertical section below the trunnions.1 f l y Like letters of reference refer to like parts in the different views.
l `am aware that H. Bessemer has made certain improvements in steel-converting vessels, patented December 5,1865,No.51,399,
and which I do not claim; but my improve;
ment in the construction and arrangement of converting-vessels relates tosc connecting the i upper and lowerfsections that the base of the lining of the upper section is in contact with the face ofthe lling in the lower section,
`this jointor connection of the two sections being inline with the topof the tu-yeres, and
so arranged that the` bottom section may be easily and readily attached, forming a proper joint, and detached with the least possible inl jury tothe lining, as more'fully hereinafter set forth.
In `the drawing, A, "Fig. 1, represents the .casing orbody of uppersection of the converting-vessel, with curved sides, and B the lower section or bottom, with the outside casing; C, the tuyeres;` and D chamber below,
into which the air is conveyed inthe usual way, and forcedthrough the tuyeres to act upon "the molten Amass in the chamber` A.
` y Vhen' the bottom section is removed the liningin the upper section is retained in` place. by the curved form below the trunni'ons.;
hence no supportis required at the bottom or base of the lining.l The vessel is hung upon ltrunnions and `provided with a nozzle at the the tuyeres in the lower section, as it extends above said joint into .the base of the chamfV ber. These are serious objections to both of these plans, and the evils attendant are well understood by those skilled in the art. Ease and facility of attaching and detaching Vthe bottom or lower section of a converter to` the upper section with` the least possible injury to the lining of the chamber are a desideratum in this `process when expedition is required. To avoid these difficulties and objections attendant upon the usual manner of construct# ing and arranging the sections of converters j is the object of my improvement, and which consists in so attaching the lower section that the surface or face F across the top of the tuyeres forms a plane, or nearly, in line with the base of the chamber A and lining, as in- Y dicated by the joint or line a, Fig. 2that is to say, the surface F across the tuyeres is made without any part raised above the lian ge of the bottom casing, as noted by the line aa; hence the base of the lining E and the flange of the upper casing are in a common line with the surface or face F and plane of the bottom casing. i
By this manner of attaching the upper and lower sections there can be introduced loe-V tween the joint graphite or other suitablematerial to prevent the lining E from being cemented with the filling D of the bottom by fusion when subject to the intense heat of the molten metal in the chamber A', hence the old bottom or section B can in this way, it is found, be quickly and easily removed and a new one readily attached without injury to the lining of the chamber or delay in the process of manufacture.
The importance of connecting and detaching the bottom with ease and facility without breaking down or injuring the lining is" Well understood in the nrt to which this invention belongs.
A and the surface F of section B shall be in line, or :nearly so, at the joint a, When the seotions, constructed substantially as described, are connected together, as and for the purpose set forth.
