SPECIFICATION forming part of Letters Patent No. 498,670, dated May 30, 1893.
Application filed June 2, 1892` Serial No. 435,306. (No model.) i
To all whom it may concern:
Beit known that I, MAXIMILIAN MANNA- BERG, a subject of the Queen of Great Britain, residing at the Frodingham Iron and Steel Works, Frodingham, in the county of Lincoln, England, have invented certain new and useful Improvements in the Construction of Steel- Smelting Furnaces, of which the following is a specification.
The invention has for its object improvements in the construction of steel smelting furnaces of the class called regenerating furnaces, whereby the regenerators vcan be repaired Without interfering with or injuring the furnace, the furnace can expand and contract without injuring the regenera'tors, and the possibility of the air and gas mixing in their passage to the furnace is `reduced to a minimum. For this purpose I support the hearth of the furnace on girders carried by columns, instead of, as heretofore supporting it on brickwork above the roofs of the regenerators, and I build the air and gas regenerators and their inlet and outlet passages in pairs on each side of the free space left underneath the furnace; the main air and gas regenerators and the channels leading into the same, occupy the lowest part of the brickwork, and the inlet channels are fitted with valves as usual, whereby the direction of the air and gases can be reversed at will. The main gas regenerator is preferably arranged with its length at right angles with that of the main air regenerator, and the said main gas regenerator communicates witha supplemental gas chamber or regeneratorat a slightly higher level. This supplemental gas chamber receives all dirt, slag, &c.,is free of chequer bricks, can very easily be cleaned, and pro-` tects in that way the main gas regenerator. The passages from the air and gas regenerators to the furnace are mainly vertical, they are parallel with each other, and they lead at their upper ends into short flues or passages opening into the furnace and constructed at different levels. The bed of the furnace is at its sides supported also on girders carried by the brickwork, and immediately above such side girders, are cold air tubes or channels. The bed of the furnace can be freely inspected from below, and the air and gas lues being completely independent from and not crossing each other, as is generally the case, there is less probability of leakage from the one to the other, the partition wall of the regenerators is not weakened, and the brickwork is more easily built and repaired.
In order that my said invention may be more clearly understood and readily carried into effect, I will proceed aided by the accompanying drawings, more fully to describe the same.
In the drawings, Figure l is a cross section `a vertical section of parts drawn on the line 5 5 of Fig. I.
In all the figures like parts are indicated by similar letters of reference.
ais the hearth of the furnace, which I support on girders b carried by columns c, instead of, as heretofore, supporting it on brickwork above the roofs of the regenerators. a a are the charging doors, and a2 are openings for examining the wall on the charging side, and a3 is the tapping hole. A free space d is left underneath the furnace bottom, and on each side of such free space l build the air and gas regenerators e and ff* and their inlet passages e f and'outlet passages @2f2 in pairs. The Amain airand gas regenerators e f, and the channels e f leading intothesame, occupy the lowest part of the brickwork, and the inlet channels are fitted with valves e3 f3 as usual, whereby the direction of the air and gases can be reversed at will. The main gas regenerator f is preferably arranged with its length at right angles with that of the main air regenerator e, therebyobtaining a con- Venient arrangement, and the main gas vregenerator fcommunicates with the supplemental gas chamber or regenerator f f, which latter is built at a slightly higher level and is easily cleaned through manhole fm. The passages 62 f2 from' the air and gas regenerators to the furnace are mainly vertical, theyare par- IOO allel with each other, and the arrangement of the regenerators enables me to construct them in such Way that they do not cross each other and do not weaken the partition Walls of the regenerators, and they terminate at the upper ends in short inclined flues or passages opening into the furnace and constructed at different levels. The bed a of the furnace is at its sides supported also on girders g, gcar- In a smelting furnace, the combination of the bed supported on cross girders carried by columns and side girders carried by the brick- Work, a free space below the bed to allow inspection, the air and gas regenerators con structed in pairs and arranged below and on each side of the free space with their longest horizontal axes extending at right angles to each other, a supplemental gas chamber arranged above each of the gas regenerators and in single blocks of brickwork on each side of the furnace, suitable iiues orpassages communicating With the furnace and extending mainly in a vertical direction parallel with each other so as not to cross, and suitable cold air tubes above the supporting girders, substantially as set forth.
