Description

[0001] ADJUSTABLE MODULAR UP DRAWING UNIT PROVIDING ULTIMATE PRODUCT VARIETY IN CONTINUOUS UP CASTING PROCESSES

[0002] The system of the present invention relates to an adjustable modular drawing unit that enables the production of metal products of different diameters without the need for assemblydisassembly by moving the drawing block horizontally with the channels of different diameters in the drawing rollers and provides end product diversity in continuous up casting processes.

[0003] The process of ensuring that the molten metal in the chamber solidifies in a certain crosssection with the help of a mold by cooling the area where solidification begins is called continuous casting.

[0004] In the continuous casting method, the need for manpower is reduced and working conditions are also much improved. One of the most superior aspects of this method, which is still under development, is its very high casting efficiency. As it is known in the current industry, a hollow area is formed in the ingots during solidification in block casting. After contacting the rollers, these hollow areas of the parts must be cut. In continuous casting, since said block is cast continuously, solidification continues continuously from one side of the block, thus hollow area losses are eliminated. Thus, compared to classical ingot casting, the efficiency is over 95% in the continuous casting method.

[0005] In existing systems using the continuous up-casting process, metal rods such as copper, copper alloys, etc. can be produced from melting furnaces with the up-casting system. In these processes, there is a hammer system to ensure the production of copper rod from molten copper. The drawing system consists of motor-reducer, belt-pulley group, shafts and drawing rollers connected to them. The production of copper, copper alloys, etc. rods consists of standards with diameters between 8 mm and 25 mm. For the production of these product types, different drawing rollers are required and the motor-reducer, belt-pulley group, shaft and drawing rollers in the drawing system are disassembled one by one in order to produce product types with different diameters each time. Then the drawing rollers are replaced and reassembled again and again. This replacement process stops production for a long time.

[0006] Existing systems that use a continuous up-casting system can only shot one product at a time. When you want to produce different product groups, assembly and disassembly times are very long. Disruptions that may occur in this process also delay the restart of production. During this process, it is necessary to continuously provide energy to maintain the temperature of the molten metal in the furnace. This situation increases the energy cost during the installation period. In addition, during the disassembly and assembly process, metal components / tools such as bolts, nuts, hammers, etc. may fall into the furnace located in the lower part of the drawing system. This spoils the purity of the copper in the furnace. The targeted impurity stands out as an undesirable situation.

[0007] With our inventive system, it is possible to produce copper, copper alloys, etc. rod standards with innovative drawing design in continuous up-casting processes. The main object of this design in the inventive system is to enable easy switching between products without assembly and disassembly. Unlike the existing systems, as can be seen in Figure 2 and Figure 3, with the new design, the motor-reducer, belt-pulley group, shafts and the drawing rollers connected to them in the drawing system are gathered on a single block. With the help of the channels of different diameters in the drawing rollers, the block can be moved horizontally and products of different diameters can be produced without the need for assembly-disassembly.

[0008] With the new design of the adjustable modular unit, which provides end product diversity in the continuous up-casting processes, energy consumption has been reduced with the replacement process that takes place in very short periods of time. Since assembly-disassembly operations are not required, metal components / tools such as bolts, nuts, hammers, etc. are prevented from falling into the furnace and copper purity can be maintained. The cost incurred by the producer per unit time decreases as the downtime in production will be reduced to short period. The system made for achieving the aim of the invention is described herein below by means of referring to the attached figures.

[0020] The parts in the figure are enumerated one by one and the parts correspond to these numbers are defined in the following:

[0021] 1- Drawing block la) Drawing block body lb) Drawing roller

[0022] Ibl) Drawing roller channel lc) Drawing slide ld) Pressing system le) Drawing motor- reducer lf) Belt and pulley power transmission system lg) Shaft

[0023] 2- Drawing main body

[0024] 2a) Linear bearing

[0025] 2b) Adjustment screw for horizontal movement

[0026] 3- Produced copper rod The present invention relates to an adjustable modular drawing unit, that enables end product diversity in continuous up-casting processes, comprising of; drawing blocks (1) having drawing block bodies (la), drawing rollers (lb) with drawing roller channels (Ibl), drawing slides (1c), pressing systems (Id), drawing motors-reducers (le), belt-pulley power transmission systems (If) and shafts (1g); drawing main body (2) having linear bearings (2a) and adjustment screws for horizontal movement (2b).

[0027] In the up-casting systems, products with diameters between 8 mm - 25 mm can be produced in the sector, while with the system of the present invention, copper rods, pipes, etc. with diameters between 8 mm - 25 mm or smaller than 8 mm or larger than 25 mm can be produced according to customer request. These products can be produced by solidifying them with water-cooled pipes called crystallizers.

[0028] Copper rod production of different diameters occurs at different speeds. In the design of the system subject to the invention, there are two separate drawing blocks (1). The drawing block (1) is the element that collects the drawing rollers (lb), the drawing motor - reducer (le), etc. group on the drawing block body (la), which performs the function of up drawing the copper rods (3), as a single block that can move horizontally. It is designed as 2 separate blocks. Each drawing block (1), is driven by the drawing motor-reducer (le). There is a separate drawing motor - reducer (le) for each drawing block (1), and copper rod (3) can be produced from 2 drawing blocks (1) at different speeds and with different diameters.

[0029] Drawing roller channels (Ibl) of different diameters are opened on the drawing roller (lb) as shown in Figure 4. The object of the drawing roller channels (Ibl) is to fulfil the drawing function without damaging the form of the copper rod (3) during production. There are drawing rollers (lb) on the shafts (1g). The drawing rollers (lb) are fixed to the shafts (1g). There are idle drawing rollers (lb) in front of the pressing systems (Id). The drawing function is performed by mutually working the drawing rollers (lb). There are lower and upper drawing roller (lb) groups on the drawing block (1). The drive transmission to these two drawing roller (lb) groups is provided by the belt and pulley power transmission system (If). The appropriate drawing roller channel (Ibl) is selected according to the diameter of the copper rod (3) to be produced; the drawing block (1) is moved horizontally by means of drawing slides (1c) placed on linear bearings (2a) in the drawing main body (2) where the modular unit is placed as a whole; the crystallizer is vertically coaxialized with the center of the selected drawing roller channel (1 bl ); the drawing block (1) is fixed on both sides by means of adjustment screws (2b) on the drawing main body (2) and the drawing process can be resumed for the production of products of different diameters without the need for assembly-disassembly. The copper rods (3) coming out of the crystallizers are pulled by the drawing rollers (lb) located on the same vertical axis as the crystallizers. The pressing system (Id) is used to grasp the produced copper rod (3) and pull it upwards.

[0030] The system of the present invention cannot be limited to what is described here and the model shown in the picture. Changes can be made to the shape of the invention without depending on the material and size, the location of the parts used can be changed, the number of parts used can be changed, different parts with similar properties can be used instead of the parts used, and the system can optionally be used without some parts.

[0031] For example;

[0032] According to the desired production options, as shown in Figure 6 and Figure 7, the number of drawing blocks (1) and the number of drawing motors - reducers (le) can be increased to 4 and 4 different diameters of copper rods (3) can be produced at the same time at different speeds. The number of drawing blocks (1) and drawing motor - reducer (le) can be increased or decreased as desired.

[0033] In order to describe the system of the present invention, copper rod (3) has been mentioned above as a product; however, it is obvious that with the system of the present invention, it is possible to produce products made of all kinds of metal metals in various shapes such as filled rods, pipes, etc.
