The tundish induction heating device can keep the temperature fluctuation of molten steel in the tundish in a narrow range, realize the constant-temperature casting of continuous casting, and achieve the purposes of improving the quality of continuous casting billets and reducing the cost of the production process.
The electromagnetic induction heating upgrading and transformation of the conventional tundish becomes an important means for improving the production capacity of high-quality steel in various large steel mills. In view of the production cost of steel mills, the steel grades are produced by casting with old tundish (as shown in figure 1), which requires that the trunnion positions of the old and new tundish should be adapted to the tundish car at the same time.
Disclosure of Invention
The invention aims to provide a modification design method of an electromagnetic induction heating tundish, aiming at the problem that a tundish car and a tundish tipping device are compatible with a new tundish and an old tundish in the electromagnetic heating upgrading modification project of the old tundish.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for improving and designing an electromagnetic induction heating tundish comprises the steps of designing three trunnions on a new induction tundish, designing two guide grooves on a tundish car, enabling the two trunnions of an original tundish to be in place on one guide groove and a support seat respectively, enabling the two trunnions of the new induction tundish positioned at the outer side to be in place on the other guide groove and the support seat respectively, and enabling the distance from the trunnion positioned in the middle of the new induction tundish to the trunnion positioned at the outer side to be equal to the distance between the two trunnions of the original tundish.
Further, an electromagnetic heating iron core is added in the impact area of the new induction tundish.
Furthermore, the new induction tundish is expanded to ensure that the capacity of the new induction tundish is the same as that of the original tundish, and the gravity center of the molten steel in the new induction tundish moves to an impact area after the expansion.
In one embodiment of the present invention, the center of gravity of the new induction tundish moves to the impact area direction by a distance of 600 to 800 mm.
In one embodiment of the invention, the distance between two trunnions of an old tundish is 950mm, a guide groove A and a guide groove B with the distance of 340mm are designed on a tundish car, a support seat C is arranged on the right side of the guide groove B, the distance between the support seat C and a guide part B is 950mm, a new induction tundish is designed with a trunnion p, a trunnion q and a trunnion r, the distance between the trunnion r and the trunnion p is 950mm, when the tundish car is in place, the trunnion p is installed in the guide groove A, the trunnion q is installed in the support seat C, and the trunnion r has no supporting surface.
According to the electromagnetic induction heating tundish reformed and designed by the method, when a new tundish is turned over on the tundish tipping device, two trunnions with the same distance with the two trunnions of the original tundish are clamped.
Compared with the prior art, the invention successfully solves the problem that the reformed new induction tundish and the old tundish are compatible on the tundish car and the tundish tipping device, effectively utilizes the old equipment, saves the equipment reforming cost, has strong practicability and has wide popularization value in the related tundish reforming engineering of the domestic continuous casting workshop of the steel mill.
Drawings
Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:
FIG. 1 is a schematic diagram of a legacy tundish configuration;
FIG. 2 is a schematic diagram of a new inductive tundish configuration;
FIG. 3 is a schematic diagram of an old tundish configuration;
FIG. 4 is a schematic diagram of a new inductive tundish coordination.
Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications can be made by persons skilled in the art without departing from the spirit of the invention. All falling within the scope of the present invention.
Taking the transformation of a certain steel tundish as an example, in the transformation design, because the electromagnetic heating iron core is additionally arranged in the new induction tundish impact area 1, the position of the newly-added induction iron core occupies the inner cavity space of the original tundish, and in order to ensure that the tundish capacity is not changed, the expansion design of the tundish must be carried out. As shown in figure 2, after expansion, the gravity center 2 of molten steel in a new tundish moves to an impact area 1, and the gravity center of the tundish moves to the impact area by a distance of 600-800 mm after modification due to the weight of an electromagnetic iron core which is approximately 10 tons.
As can be seen from FIG. 2, if the original trunnion position dimension L1950mm is maintained, the center of gravity of the new tundish is already beyond the position between the two trunnions, and the tundish is prone to tipping over during casting and maintenance, which can cause safety accidents. When two trunnions are clamped on the original tipping equipment to turn over the tundish, the tipping capacity of the original driving system is insufficient due to the fact that the tipping moment arm is increased, and meanwhile, the tipping outline is increased and possibly interferes with surrounding equipment and civil engineering, so that upgrading and reconstruction must be carried out.
In order to solve the compatibility problem of a new tundish and an old tundish on a tundish car and a tipping platform, the invention provides a method for improving and designing an electromagnetic induction heating tundish. As shown in fig. 3 and 4, the dotted line represents the modified design outline of the tundish car, A, B represents a guide groove, and C represents a fixed support seat.
The distance L1 of two gudgeons of old tundish is 950mm, design interval is L2 also for 340 mm's guide way A and guide way B on the tundish car, the right side of guide way B is provided with supporting seat C, supporting seat C also is L1 with leading to B interval and is 950mm, the design of package has gudgeon p in the middle of the new response, gudgeon q and gudgeon r, gudgeon r is to gudgeon p's distance for L1 also to be 950mm, when taking one's place on the tundish car, gudgeon p installs at guide way A, gudgeon q installs at supporting seat C, gudgeon r does not have the holding surface.
As shown in fig. 3, two trunnions of the old tundish are respectively positioned in a B guide groove and a C support seat of the tundish car, and the distance L1 between B and C is 950 mm; as shown in FIG. 4, the new tundish design has three trunnions p, q and r, when the tundish car is in place, the trunnion p is installed in the guide groove A, the trunnion q is installed in the support seat C, and the trunnion r has no support surface. It can be seen that the center of gravity of the new tundish is positioned between the supporting trunnions p and q, the potential risk of tipping is eliminated, and the requirement of safe production is met. The distance from the trunnion r to the trunnion p is equal to the distance from the two trunnions of the original tundish, and when the tundish of the overturning platform is overturned, the trunnion p and the trunnion r are clamped, so that the overturning platform can adapt to the assembly size of the original overturning platform, can also effectively reduce the overturning moment, and the original power system does not need to be upgraded and reformed.
The invention successfully solves the problem that the modified tundish and the old tundish are compatible on the tundish car and the tundish tipping device, effectively utilizes the old equipment, saves the equipment modification cost, has strong practicability, and has wide popularization value in related modification projects of the tundish of the continuous casting workshop of the steel mill in China.
