In addition, because the fuel is added in the closed cavity, the fuel will not float and disperse due to being directly added into molten steel. In addition, the through hole can be used for observing the internal composition of the packing block, and the molten steel and airflow can flow through the through hole during the scrap steel smelting process, so that the smelting of the scrap steel is accelerated.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal packing machine, metal packing block, and in particular to a metal packing block, a pressing mold, a pressing device and a method. BACKGROUND

[0002] In order to improve the scrap steel ratio in the steel production process, Professor Chen Linquan theoretically calculated and analyzed the melting of scrap steel in molten iron and molten steel, and conducted field verification. The melting process of scrap steel in molten iron is usually at a temperature of 1250-1500 DEG C, and the melting point of scrap steel is above 1500 DEG C. Because the melting point of scrap steel is higher than the temperature of molten iron, according to the thermodynamic model and test of scrap steel melting, the melting process of scrap steel in molten iron is as follows: in the initial stage of melting, the temperature difference between scrap steel and molten iron is large, and the molten iron solidifies on the surface of the scrap steel to form a solidified layer; with the extension of time, the temperature of the scrap steel rises, and the solidified layer on the surface begins to melt; carbon in the molten iron mass transfers to the surface of the scrap steel to form a carburized layer; the temperature of the scrap steel continues to rise, the carbon content on the surface of the scrap steel increases, and the melting point decreases; when the melting point of the carburized layer on the surface of the scrap steel is lower than the temperature of the molten pool, the scrap steel melts to form a liquid. Then the surface of the scrap steel repeats solidification -> carburization -> melting until the scrap steel is completely melted. Therefore, the limiting link of the melting of scrap steel in molten iron is the mass transfer of carbon on the surface of the scrap steel.

[0003] The scrap steel is made into a packing block, which is convenient for storage, transportation and charging for recycling, and the loss is extremely low, which is an effective way of scrap steel processing, but the scrap steel packing block has a large volume and is compact inside, which is not conducive to heat transfer, mass transfer, conduction, convection and radiation, and also not conducive to observing the composition inside the scrap steel.

[0004] Currently, there is a method of adding fuel in the converter, but when the scrap steel is smelted, the fuel will directly float to the surface of the molten steel, which cannot fully contact and heat the scrap steel, thereby reducing the smelting efficiency of the scrap steel.

[0005] The present application is directed to the improvement of the existing process, and provides a metal packing block, a pressing mold, a pressing device and a method, in order to improve the technical effect of the use efficiency of the scrap steel block. SUMMARY

[0138] The following table shows the smelting conditions using the metal packing blocks of Comparative Examples 1-3 and Example 1 above

[0139]

[0140] In Example 2 and Comparative Example 2, due to the addition of the through hole design, the molten steel can fully contact and exchange heat with the packing block, accelerating the melting of the metal packing block.

[0141] Although the fuel increases the total heat of the molten steel, if the fuel is heated by floating to the surface of the molten steel and the effect of heating in the metal packing block, there is a gap between the effects.

[0232] Step six D: take out the pressed intermediate block 2 in the packing chute 51, and the pressing is completed.

[0233] Example 18: To prevent fuel from leaking out

[0234] Since the axis of the cavity groove is perpendicular to the ground in example 14, example 14.1, example 15, example 16, and example 17, and the fuel is mostly in the form of powder, it is difficult to add fuel into the cavity groove, and if the fuel is made into a cylindrical shape, it is very likely that the quality of the final smelted steel will be affected due to the addition of other impurity elements (such as hydrogen, organic elements, etc.) in the adhesive.

[0235] Therefore, example 18 is proposed to add fuel into the cavity groove.

[0236] S1: first, place a half-metal packing block 1 that has been pressed in example 14, example 14.1, example 15, example 16, and example 17 with the pressing surface facing up into the metal pressing machine;

[0237] S2: Add the required fuel in the cavity groove;

[0238] S3: Put another half metal baling block 1 on the half metal baling block 1 with added fuel, and make sure that the installation groove 11 and the installation block 12 are aligned;

[0239] S4: Start the top compression cylinder 81 of the metal compressor 8, and press the installation block 12 into the installation groove 11 completely (since the installation block 12 and the installation groove 11 are interference fit or transition fit, there is a gap after placement), and then stop the top compression cylinder 81;

[0240] S5: Start the side compression cylinder 82 of the metal compressor 8, and fix the half metal baling block 1 in the horizontal direction;

[0241] S6: Continue to start the top compression cylinder 81 of the metal compressor 8, and extrude the installation block 12 and the installation groove 11, and the two half metal baling blocks 1 are pressed into metal baling blocks.

[0242] The metal compressor in this embodiment is a prior art, and the specific structure and use method are not described here. In this embodiment, the specific pressing sequence should be paid attention to.

[0243] In addition, the points that should be paid attention to by those skilled in the art when using the equipment in the above embodiment are:

[0244] Since the mold has a protruding surface, when pressing scrap steel, in order to prevent the mold from being worn, scrap steel with lower hardness can be selected for pressing.

[0245] Since the closed cavity and the through hole of the finally pressed metal baling block are circular in cross section, the through hole groove 13 and the closed groove of the half metal baling block 1 should consider the deformation caused by secondary pressing, so the cross section of the through hole groove 13 and the closed groove should be half-elliptical, and the specific shape can refer to the existing hole type design method of rolling steel.

[0246] If the closed cavity and the through hole of the finally pressed metal baling block are not circular in cross section, the cross section of the through hole groove 13 and the closed groove of the half metal baling block 1 does not need to be half-elliptical.

[0247] In order to fix the lower pressing plate 53 and the baling groove 51, a lock rod 533 is arranged at the end of the lower pressing plate, and a lock hole 511 is opened at the corresponding position of the baling groove 51.

[0248] Since the mold is arranged at the end of the lower pressing surface of the lower pressing plate 53, part of the mold will be blocked by the inner wall of the baling groove 51 when the lower pressing plate 53 rotates, so a certain arc can be arranged on the inner wall of the baling groove 51 (such as Figure 28), the center of the arc surface where the arc is located coincides with the axis of the rotating shaft of the lower pressing plate 53, facilitating the rotation of the mold.

[0249] In the embodiments 14, 15, 16 and 18, the steel scrap is pressed twice, and if the steel scrap is pressed too densely in the first pressing, it is not conducive to the second pressing. Therefore, the loading force of the vertical pressing block 52 needs to be properly controlled in the first pressing, and the maximum loading force of less than 50% is preferably selected, and the maximum loading force of more than 50% is selected in the last pressing.

[0250] In the scheme of using double vertical pressing blocks 52 and double-sided molds 4, the loading forces of the two vertical pressing blocks 52 can be the same, but because the amounts of steel scrap on both sides of the double-sided mold 4 are not necessarily the same, the degrees of deformation of the steel scrap on both sides are different, thereby causing the double-sided mold 4 to be excessively pressed by the steel scrap on one side. Therefore, the double-sided mold 4 can be connected to the double-sided mold 4 through the mold guide rail 534 on the lower pressing surface of the pressing plate 53 (such as Figure 30 ), so as to prevent the double-sided mold 4 from being excessively pressed by the steel scrap on one side due to the different degrees of deformation of the steel scrap on both sides. In the scheme of using the rotating plate 6, a similar rail connection method can also be used to reduce the excessive pressing of the double-sided mold 4 by the steel scrap due to the different degrees of deformation.

[0251] If the installation groove 11 and the installation block 12 fail to connect the two half metal packing blocks 1 firmly (to prevent the structure from being disassembled during subsequent transportation), a layer of glue can be applied to the installation groove 11, the installation block 12 or the surface to be connected before pressing to facilitate connection. In the case of particularly difficult combination, welding or spot welding can also be selected to combine the two half metal packing blocks 1 into a metal packing block.

[0252] In the embodiments 14, 15, 16 and 18, the coke can be added manually or by a feeder. If a feeder is used for addition, a metering scale can be considered to be arranged at the bottom of the packing groove 51 or the metal compressor to add fuels of corresponding types (silicon, coal, etc.) and qualities according to the mass ratio of the metal packing block to be added in the future smelting steel scrap and the final smelting steel demand.

[0253] The following table shows the time and the number of equipment for pressing a metal packing block in the embodiments 14, 15 and 16.

[0254]

[0255] The cost of the equipment modification in embodiment 14 is the lowest and the requirement for materials is also low, only the longitudinal pressing block of a common metal packing machine needs to be modified, but a common metal packing machine is also needed to press the two half metal packing blocks 1 again, and the half metal packing blocks 1 need to be carried multiple times in the process, so the time is long.

[0256] Embodiment 14.1 can greatly reduce the cost of the equipment without the requirement for the surface of the metal packing block, but the pressing time is still consumed because of multiple pressing and carrying, so not much time is saved. Embodiment 14.1 is the most cost-saving embodiment, so it is the best implementation when the initial investment of the operator is insufficient and there is no requirement for the surface of the metal packing block.

[0257] Embodiment 15 is the fastest metal packing method, but the requirement for the material of the mold is relatively high, and the mold is easy to be squeezed and damaged, so the pressing cost is not necessarily lower than that of embodiment 14, whether from the long-term operation or the initial construction, but if the mold has a breakthrough in the material, it is undoubtedly the best pressing scheme.

[0258] Embodiment 16 is an improvement of embodiment 15, which aims to increase the pressing capacity of the equipment for multiple types of products. In particular, the half metal packing block 1 and the intermediate block 2, and the metal packing block without surface requirement.

[0259] In summary, the metal packing block and the pressing mold, the pressing equipment and the method design a brand-new metal packing block structure, including a closed cavity and a through hole, fuel can be added in the closed cavity, which reduces the amount of molten steel required for scrap steel smelting to provide heat and increases the smelting ratio of scrap steel. At the same time, because the fuel is added in the closed hole, it will not float on the surface of the molten steel because the fuel is added to the molten steel. Filling fuel in the packing block can effectively solve the limiting link of scrap steel melting in molten iron, that is, the mass transfer of carbon on the surface of scrap steel. In addition, the through hole can be used to observe the internal composition of the packing block, and the molten steel and airflow can flow through the through hole during the scrap steel smelting process to accelerate the smelting of scrap steel.
