(14) The present disclosure relates to a system for casting by splitting molten materials as shown in FIG. 1, more particularly, a system for producing ferrosilicon (Fe—Si), ferromanganese (Fe—Mn), ferrosiliconmanganese (Fe—Si—Mn) by melting and casting them with a predetermined size to be used as auxiliary materials for a steelmaking process.

(15) Ferrosilicon or ferromanganese discussed herein is an auxiliary ferroalloy which is used for making steel or cast iron; specifically, ferrosilicon is used as a deoxidizer and a reducing agent and as a graphitizing agent for making carbon steel.

(16) A system for casting by splitting molten materials according to the present disclosure is for producing a plurality of unit form products with a predetermined size by using molten materials (molten auxiliary materials for steelmaking) received from a furnace 1.

(17) In general, producing auxiliary casting materials for steelmaking requires a step of crushing, whereas a system according to the present disclosure enables casting auxiliary materials without crushing, thereby preventing noise and dust, as well as a precise process for easily making the auxiliary materials with a desired size.

(18) A system for casting by splitting molten materials according to the present disclosure, as shown in FIGS. 1 and 2, comprises a body unit 100, a side packing unit 200, and a link unit 300.

(19) First, the body unit 100, as shown in FIGS. 1 and 2, forms a body for casting which receives a molten material from the furnace 1.

(20) The body unit 100 is a configuration wherein the molten material is received, cooled down, and then the cast molten material is released from the body unit to be used as an auxiliary material for steelmaking.

(21) The side packing unit 200, as shown in FIGS. 6 and 8, is disposed at a front and a rear of the body unit 100 partially covering the body unit 100.

(22) Herein, the front indicates a direction the body unit 100 moves forward and the rear indicates the opposite direction thereof.

(23) The side packing unit 200 not only covers the front and rear sides of the body unit 100 but also, when the body units are connected to each other, makes them into an infinite loop thereby helping the body unit 100 easily moves.

(24) And the side packing unit 100, formed of a copper alloy, covers the front and rear of the body unit 100, thereby preventing the body unit 100 from being exposed directly to heat.

(25) The side packing unit 100, as it is made of a copper alloy, can prevent the body unit 100 from being damaged by the molten material of a high temperature provided by the furnace 1.

(26) The link units 300, as shown in FIGS. 1 and 6, are provided at both sides of the body unit 100 so as to connect a plurality of the body units 100.

(27) The link units 300 connect a plurality of the body units 100 and move them in an infinite loop so as to cast molten materials with a predetermined size, thus producing a plurality of unit form products.

(28) The body unit 100 of a system for casting by splitting molten materials according to the present disclosure, as shown in FIG. 7, comprises vessels 110 and subvessels 120.

(29) First, the vessels 110, as shown in FIGS. 2 and 3, provide a plurality of upward concave receptacles, into which the molten materials are poured.

(30) The vessels 100 are a plurality of receptacles into which the molten auxiliary casting materials received from the furnace 1 are filled. The cast molten materials become individual unit form products.

(31) The vessels 110 of a system for casting by splitting molten materials according to the present disclosure, as shown in FIG. 4, each comprise a barrier 111 and a floor 112.

(32) The barrier 111 forms an exterior wall of each of a plurality of the receptacles.

(33) The barrier 111 surrounds and defines a plurality of the receptacles.

(34) The floor 112 forms a flat bottom surface of each of a plurality of the receptacles.

(35) As shown in (a) of FIG. 4, the floor 112 and the barrier 111 meet each other with an angle forming a discontinuous junction such that the molten materials cast in a plurality of the receptacles can be easily released therefrom.

(36) Herein, the angle forming a discontinuous junction is, preferably, bigger than the right angle) (90° but smaller than the straight angle (180°).

(37) The barrier may be curved or flat without being limited to a specific form but, preferably, with an obtuse angle forming a discontinuous junction.

(38) The floor 112 has a flat surface and an angle forming a discontinuous junction, such that the cast molten materials can be produced as a polygonal shape.

(39) The subvessels 120, disposed adjacent to a plurality of the receptacles, provide additional spaces with a shape of upward concave hemisphere.

(40) The subvessels 120 provide a plurality of additional spaces smaller than a plurality of the receptacles of the vessels 110. And a plurality of the additional spaces are formed each to surround each of a plurality of the receptacles.

(41) With the subvessels 120, a single body unit 100 can produce as large an amount of the auxiliary materials as possible.

(42) As shown in FIG. 4, a subvessel 120 comprises a splitting partition 121.

(43) The splitting partition 121 is configured to divide the vessels 110 into a plurality of receptacles such that molten materials are divided and received by a plurality of the receptacles and subvessels 120.

(44) The splitting partition 121 is a flat surface between a plurality of the receptacles and a plurality of the additional spaces.

(45) The splitting partition 121, as shown in (b) of FIG. 4, may have a peak 122, which is an upward protrusion disposed at its center, such that molten materials poured into a plurality of the receptacles and a plurality of the additional spaces can be easily divided and received thereinto.

(46) For example, a molten material of a normal or low viscosity can be easily divided and received by a plurality of the receptacles and the additional spaces, whereas a molten material of a high viscosity will not easily be divided; thus a peak is provided to facilitate the division and separate accommodation of the molten materials.

(47) In addition, the auxiliary material produced by a system for casting by splitting molten materials according to the present disclosure is configured to have a size between a minimum of 10 mm and a maximum of 50 mm.

(48) The reason why such a limitation is imposed to the size of the auxiliary materials is because a material bigger than 50 mm tends to precipitate in the steelmaking process thereby causing defects of the products whereas a material smaller than 10 mm tends to be oxidized before achieving its intended effect.

(49) Therefore, the auxiliary materials should be produced with a size of 10 mm 50 mm by the body unit 100.

(50) For such a purpose, as shown in (a) of FIG. 5, the diameter (D1) of each of a plurality of the receptacles and the diameter (D2) of each of a plurality of the additional spaces are configured, preferably, to be 10 mm<D2<D1<50 mm.

(51) Likewise, as shown in (b) of FIG. 5, the volume (V1) of each of a plurality of the receptacles and the volume (V2) of a plurality of the additional spaces are configured, preferably, to be Vmin<V1<V2<Vmax.

(52) Herein, Vmin represents the minimum volume of the auxiliary material, and Vmax the maximum volume thereof used for a steelmaking process.

(53) The side packing unit 200 of a system for casting by splitting molten materials according to the present disclosure, as shown in FIGS. 6 and 8, comprises a forward packing 210 and a backward packing 220.

(54) First, the forward packing 210 is disposed at the front of the body unit 100 with its top portion protruding upward higher than the top of the body unit 100.

(55) The forward packing 210, as shown in FIG. 6, has a forward peak 211.

(56) The forward peak 211, disposed at the top of the forward packing 210, protrudes upward higher than the top of the body unit 100 thus partially covering the backward packing 220.

(57) The backward packing 220, disposed at the rear of the body unit 100, protrudes upward higher than the top of the body unit 100 as well as protrudes backward.

(58) The backward packing 220, as shown in FIG. 6, comprises a backward peak 221.

(59) The backward peak 221, disposed at the top of the backward packing 220, protrudes upward higher than the top of the body unit 100 and also protrudes backward from body unit 100.

(60) When a body unit 100 is connected to another body unit 100, a backward packing 220 of one body unit comes into contact with a forward packing of the other body unit 100.

(61) That is, with body units connected in a series, a forward packing 210 comes into contact with a backward packing 220, in which a forward peak 211 protruding upward partially covers a backward peak 211 protruding upward and backward because of a height step there between.

(62) The scope of the present disclosure is determined by the appended claims, and the parentheses used in claims are intended not to indicate an optional limitation but to more clarify the configuration thereof; therefore any limitations in parentheses should be understood as essential to the disclosure.
