Andrzej Pudlik, Antoni Caputa, Leszek Chomicki Authorized by a temporary patent: Biuro Projektów Przemyslu Hutniczego“ Biprohuf1 Przedsiebiorstwo Panstwowe, Gliwice (PofskaJ System of cooling plates of a blast furnace. The invention concerns the arrangement of cooling plates of a blast furnace. Until now, cooling plates of a shaft and a room of a blast furnace, as well as a range and a shaft were a cooling system built on the following principle: for example, the distances between the plates were constantly or 40 millimeters, as well as the distance between the external wall of each chilling plate and the armor of the blast furnace was also fixed in size and amounted to approximately 30 or 40 millimeters. Such a panel composition required the use of profile plates selected and adjusted for each strip and each angle of inclination of the roof. such was characterized by the fact that for the production and compliance with the assumed dimensions, a plate they had different radii of curvature, different taper and width dimensions, separate for each cooling strip. This created a number of difficulties and additional troubles, such as the need to precisely number the discs so as not to confuse them. In the case of cast plates, it is necessary to make a large number of models without the possibility of automating the casting process. The aim of the invention is to avoid the above-mentioned inconveniences and inconveniences, and this is by unifying the shapes and dimensions of the plates with the possibility of simplifying the production of these cooling plates. This aim was achieved by that the cooling plates of the shaft and the room, as well as the hearth and the hearth have the same dimensions and shape so that the gaps-distances between them are from twenty to sixty millimeters, and the distance between these plates and the armor of the blast furnace is from ten to about sixty millimeters, with these spaces filled with a known filling mass. The arrangement of cooling elements of the blast furnace in this way demonstrates the same cooling advantages as before, so it does not worsen the heat dissipation conditions, because the average thickness of the filling layer has not changed, but the execution of the panels has not changed. becomes clear badly improved. The same chilling plates do not require a painstaking numbering in their storage and assembly, they allow for direct plate replacement in the event of failure during assembly. The dimensions of the plate allow for their serial production, both in the welded and cast version, but the production of cast plates can be automated and made with one, and at most two or three models, while in the previous blast furnaces for each belt were made at least 2 Models. 2 -76 095 The refrigeration system is explained in more detail in the embodiment shown in the drawing in which fig. 1 shows a diagram of the cooling system of a blast furnace in a vertical half-section, fig. 2 - a side view of the cooling plate system, and fig. 3 - a layout a plate that has a smaller radius of curvature than the radius of the blast furnace shell in the top view, and fig. 4 - the layout of the chilling plate which has a greater radius of curvature than the radius of curvature of the blast furnace in the top view. The cooling system consists of cooling plates 4 positioned as before in the vicinity of the armor 3 and separating this armor 3 from the lining 2. Refrigerating plates 4 have the shape of rectangles or better trapezoidal planes the planes of the armor 3, on the other hand, in the top view, they are fragments of the ring or, in an extreme case, they are not made in an arc, but straight, depending on the radius of curvature of the armor and the width of the cooling plate. The choice of the shape of the plate and its dimensions should be based on the assumptions that the distances between the plates 4 are kept between a minimum of twenty millimeters and sixty millimeters, and that the distance between the plates 4 and the shell 3 of the blast furnace 1 is from ten to seventy millimeters. The coolers 5 in the slope zone remain unchanged and are carried out as before. Likewise, the cooling plates 6 in the area of the nozzles are specially made, they have bypasses for their outlet and constitute a group of plates not covered by this patent. The plates 7 in the hearth and hearth area must be made according to this patent, with the maintenance of the distances. The spaces between the plates 4 and 7 as well as between them and the armor 3 should be filled with the previously known filling material - mass. Connection of cooling plates with water pipes, not shown in the drawing, is made as before, with the fact that both the spacing of the plates and their connection do not have to be separately drawn up for each row, as according to the invention, the spacing of cooling pipe outlets is for each plate as well as the plates themselves are the same. The refrigeration system according to the invention allows, as mentioned, the unification of the cooling elements, their easy production in large series, and moreover, allows the plates to be interchangeable between different blast furnaces. Storage and management of the discs is greatly simplified, and even in the event of damage to the disc during transport, it allows for its exchange. An additional advantage of the invention is that the cooling coils in the slabs also have the same shape and dimensions. PL PL
