Definitions
- This invention relates to a compact reversible universal mill for producing medium-large sections.
- reversible mill in the third solution provides various advantages over the continuous mill in the first two, but the main factor is essentially the lower initial investment cost. Indeed, reversible rolling mills reduce the number of machines required for rolling, enable smaller hangars and related structural work to be used, provide process and productivity advantages, etc.
- Patent EP 256 409 Bl from SMS describes a process for
- the X-H process solution adopted by SMS to produce sections provides for one or more reversible breakdown stands and an intermediate reversible-finishing mill (tandem) comprising a universal reducing stand, a two-high stand and a universal stand that fulfills the dual functions of reducing and
- This solution provides for the use of one or more breakdown stands, an intermediate reversible mill comprising U - H - U (like the competition) and a continuous finishing mill
- An additional stand is provided away from the intermediate reversible mill and therefore linked by roller way and located as a finishing stand near to the cooling bed.
- the last stand in the finishing mill has a duration that is 2-3 times higher than the solution in the aforementioned SMS patent generating significantly fewer stops in production to replace rolls and therefore considerably less maintenance .
- finishing stand the roller way and all of the structural work and hangars related to the longer plant increase the overall investment by the client.
- the general purpose of this invention is to resolve the aforementioned drawbacks in the prior art in an extremely simple, economical and particularly functional manner.
- Another purpose is to provide a reversible mill that is more compact than those currently available.
- Another purpose is to provide a reversible mill that minimizes plant costs related to the structural work and hangars
- this invention describes a compact reversible universal mill for producing medium-large sections, having the characteristics set out in the attached claims.
- FIG. 1 shows the key elements of a compact reversible universal mill for producing medium-large sections according to this invention
- FIG. 2 shows a first embodiment of a plant, known as "I shape", which incorporates a mill according to the invention
- FIG. 3 shows a second embodiment of a plant, known as "U shape", which incorporates a mill according to the invention
- FIG. 4 shows a third embodiment of a mixed-type plant, which also incorporates a mill according to the invention.
- a compact reversible universal mill for producing medium-large sections is
- universal mill 10 provides for the placement of a finishing universal stand 11 as the final additional stand in a
- the reversible intermediate unit 12 includes a first universal reducing stand 14, a two-high stand 15 and a second reducing universal stand 16.
- this additional stand 11 does not change as it is used always and exclusively for finishing. Therefore the stand 11 is always open during intermediate passes and is only closed before the bar completes the last pass in the
- the stand 11 therefore moves perpendicularly to the direction of movement of the bars 17 gradually worked by the stand 11 itself. This movement is for example effected by an
- This arrangement consists of an X - X - H solution using a reversible mill comprising four full stands substantially limiting the distance between the finishing stand 11 and the reversible intermediate unit 12.
- this finishing stand 11 is no longer placed away from the reversible intermediate unit 12, as described in the prior art, but is placed immediately after the last universal stand of the same reversible unit 12.
- the option of offering clients ever-more compact plants, such as those according to this invention enables involvement in contracts where the installation area is not critical, as well as involvement in contracts where the actual layout is critical to mill installation.
- Increased production offsets the higher initial cost of the plant according to the invention compared to known plants in less than one year's operation of the plant, depending on the capacity of the plant and the tons per campaign.
- the service life of the rolls of the universal finishing stand according to this invention is around 2000 [t] for smaller sections and around 3000 [t] for larger ones.
- the arrangement proposed makes the plant more compact or in any case significantly optimizes the process.
- the solution proposed generates a single-change system for the stands of the reversible mill and therefore a more compact rollshop section, a reduced and optimized use of overhead cranes, more rational use of spare parts and therefore better warehouse management.
- a furnace unit 21 with related accessories (such as descaler 23) is placed upstream before a roughing unit 24.
- a furnace unit 21 with related accessories such as descaler 23
- a roughing unit 24 is placed upstream before a roughing unit 24.
- the mill 10 according to the invention is followed by the mill 10 according to the invention before a cooling bed 27, cutting stations 29 and final stations.
- the "U shape" solution shown in Figure 3 with bed 27 further away results in any case, once the final stand is moved, in a more compact layout.
- the compact solution may enable use of the space after the finishing stand to be optimized and the distance between it and the cooling bed to be lengthened at a lower cost making it possible to roll a longer finished product from a starting section that is heavier and to cut it into
- Figure 4 shows a third embodiment of a plant that incorporates the mill according to this invention and that combines
- finishing stand has a dedicated groove that wears less over time .
