Specification of Letters Patent.
Patented Nov. 30, 1909.
Application led January 21, 1909. Serial No. 473,482.
To all whom it may concern:
Be it known that I, FRED H. DANIELS, of Worcester, Worcester county, Massachusetts, have invented a new and useful Improvement in Heat-Retainers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawin s, forming part of this specification, in whic Figures 1 and 2 are respectively horizontal and vertical longitudinal sections of the preferred form of heat retainers, and Fig. 3 is a cross section on the line III-III of Fig. l. Fig. 4 is a lan view partially in section of a modified orm of heat retainer; Fig. 5 isa side elevation thereof, partially in section; Fig. 6` is a sectional view on the line VI-VI of Fig. 4; Figs. 7 and 8 are respectively horizontal and vertical sectional views, of another modified form of heat retainer; Fig. 9 is a sectional view on the line IX-IX of Fig. 8.
My invention has relation to heat retainers for use in rolling mills.
The object of the invention is to provide a chamber, in which Hat bars of long lengths, having assed the so-called roughing part of a rolling mill, may be stored for a certain period of time, and heat so applied and regulated that the bars will have the right unin form temiperature throughout their whole len h be ore they or `nishing part of the mill. The heat retainer also provides for a convenient means of disposing of bars from the roughing mill in case the finishing mill should cobb'le or suddenly get out of order, and which, Without the retainer, would have to be run out on the floor and become scrap. The retainer may be of any suitable design depending upon the fuel used and the maximum length o the billets adopted.
The precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes can be made in the details of construction and arrangement, by those skilled in the art, without departing from my invention, as deiined in the appended claims.
In the drawings, the letter B designates the heat retainer, which, as shown in Figs. 1,
'2 and 3, preferably has a number of troughl shaped channels 2 made up of tire brick and are provided with passages are passed into the next channels to permit the free circulation of gases around the channels. These channels are arran ed one above the other, so that a number o flats may be resting in the heat retainer B at the same time. I have shown in these fi ures four of these trough-shaped channels, ut any number desired may be used. The lower layer of bricks rest on water-cooled pipes, L1, thus providing ample structural strength with minimum obstruction for the hot gases. The retainer has openings 5 in the sides thereof for theedmission of the gas from the burners, which passes up and around the bars in the channels 2, and then out through the iues (5. At each end of the retainer B are movable feed rolls 7 and 8 which are movable bodily up and down for feeding in and withdrawing iiats or bars from the channels 2. These movable feed rolls have feed tables 9 and 10 attached thereto and are swung up or down by any suitable means. It is obvious that where onl one channel Q is required, the rolls 7 an 8 and tables 9 and l() need not be movable. At the ends of the retainer B are openings 1l and 12 through which suitable gripping tongs or other tools may be iuserted to move the hot bars.
In the modification shown in Figs. 4, 5 and 6, I have shown a retainer in which the feed rolls 35 can be stationary. The flats X are delivered from the roughing mill, to the heat retainer B through one end and side thereof by means of the feed rolls 35. The fiats are fed into the heat retainer one on top of the other, two to four high. The opening from the heat retainer to the finishing mill is at the other end and side thereof. The pile of flats is pushed from one side of the heat retainer to the other side, by means of power operated plungers 36, and are fed to the finishing mill over the stationary feed roll '38. The plungers 36 can be operated by hydraulic cylinders or any other available means.
In the modification shown in Figs. 7, 8 and 9, the flats X are fed int-o one end of the heat retainer B, by the stationary feed rolls 35, and are fed to the finishing mill from the other end thereof, by means of the roll 38. The flats are delivered to the heat retainer one on top of another, from the roughing mill. The bottom piece is pushed out through the delivery end of the retainer by means of a ram 37, the engaging end of 3 between the l the ram is provided with a projection 39 whose upper end is slightly below the upper edge of the bottom flat. The delivery end of the retainer is provided with a guard 40, whose lower edge is slightly above the upper edge of the bottom llat. rl `hereby, insuring thc engagement of only one liat by the ram, and by means of the guard, preventing the drawing of the second flat by frictional contact. The heat in the retainer is not sutil ciently high. to cause the slabs to stick together. The retainer may be tired with oil, gas, coal or any other suitable fuel.
From the foregoing description of my ap paratus, it will be seen that my heat retainer is used in con'unction with a mill for rolling flats in the ollowing manner. The billet is first elongated by passing it through a roughing mill, from which the flats or other shapes are passed onto the movable feed rollers 7. The flats are fed in rotation by means of the feed rollers into the various channels 2 in the heat retainer B, and are withdrawn likewise in rotation, by means of the rollers S, from which they are fed to the finishing rolls. The advantages of my invention result from the provision of a heat retainer to receive the Hats after they pass from the roughing rolls, and before they pass to the finishing rolls, whereby heat can be so applied that the bars or flats will have the proper and uniform temperature throughout their length, when fed to the finislung mill. Also in providing a heat retainer in which a series of Hats can be stored between the roughing and finishing mills, thereby providing a convenient means for disposing of flats from the roughing mill if the finishing mill should get out of order, and also providing storage space from which the finishing mill can be supplied with flats if the roughing mill should be shut down for a short period.
