Description:
TITANIUM-BORON ROD FEEDING UNIT

RELATED TECHNICAL FIELD

This invention relates to a titanium-boron feeding unit which is introduced into the metal in the aluminum melting and keeping furnaces.

STATE OF THE ART

When allowing for the metal transfer to the casting machine by means of the guides at the aluminum melting and keeping furnaces, titanium-boron is introduced in order to make the particle size of the metal (aluminum) thinner and to provide a structure with fewer pores.

Titanium-boron material is supplied in rods being wound around the reel.

The process of introducing titanium-boron is facilitated by the rod feeder. In the current systems, this process is enabled by driving the reel and the gears by the power from the reactor and providing titanium-boron rods with a forward motion.

While there are three different movement groups in the current structures, only one movement group is driven and it transfers power to the other movement groups by means of the rod. This causes the system to be seized, the titanium-boron rods to change direction, and the feeding at a desired amount to fail.

Two separate rotation systems which have been measured may be intermingled because there is double rotation monitor in the present feeding units as is seen in Fig. 1.

Also, the system is deactivated over time since deformations occur in the locking form in the reels which allow the titanium-boron rods to enter the movement groups properly.

Moreover, the bearing of the movement groups in the system and the service and maintenance works of the pressure groups are performed in a more difficult way. THE OBJECT OF THE INVENTION

The object of this invention is to provide an even feeding of the titanium-boron into the liquid metal which is transferred from the aluminum melting and keeping furnaces.

Another object of the invention is to enable one driving group to keep feeding without delay while the other is being serviced because two separate driving groups is connected to the rotation monitors separately.

Another object of the invention is to increase the friction coefficient through the diamond-shaped surfaces of the reels driving the titanium-boron rods to the liquid metal. DESCRIPTION OF THE DRAWINGS

DESCRIPTION OF THE INVENTION

The titanium-boron rod feeding unit (1) comprises at least one feeding reel (1.2) having diamond-shaped rhombuses on its surface in order to increase the friction coefficient while moving the titanium-boron rod (4) to divert it into the transfer pipes (3); at least one gear reducer (1.3) having specific-shaped gears for transmitting the titanium-boron rod (4) to the transfer pipes (3) without being crushed and by keeping it at the axis; double-shaft reducer (1.1 ) which doubles the rotation speed when any problem occurs in one of the titanium-boron reels, thereby allowing for processing the titanium-boron reels (5) and feeding of the liquid metal continuously and which is connected to the feeding reel (1.2) through a gear reducer (1.3); at least one pressure spring (1.7) which applies pressure when wears occur at the titanium-boron rods (4) and at the parts providing movement to the titanium-boron rods (4) and which prevents seize and deactivation of the feeding unit (1); and the rotation monitor (1.4) being connected to the feeding reels (1.2) and controlling the predetermined feeding speeds.

The titanium-boron rods (4) are wound around the reels. The titanium-boron rods (4) from the titanium-boron reels (5) pass through the alignment unit (2) and enter the feeding unit (1) through the titanium-boron rod inlet (1.5). The titanium-boron rods (4) exits through the titanium-boron rod outlet (1.6), they are directed to the transfer pipes (3) which are connected to subsequent section of the titanium-boron outlet (1.6), and they are transferred to the liquid metal.

The gear reducer (1.3), feeding reel (1.2), double-shaft reducer (1.1), and the rotation monitor (1.4) constitute the driving group of the feeding unit (1 ) and facilitate the movement of the titanium-boron rods (4).

For the present feeding units (M), the titanium-boron rods (4) are provided with a forward movement by driving the reels (M5) and the gears via the power from the present unit reducer (M1. However, only one movement group (M3) is driven and transmits power to the other movement groups (M3) while there are three different movement groups (M3) at the present feeding units (M), as seen in Fig. 1. This causes the system to be seized, the titanium-boron rods (4) to change direction, and the feeding at a desired amount to fail.

The feeding reel (1.2) and the gear reducer (1.3) moving the titanium-boron rods (4) and guiding them towards the titanium-boron rod outlet (1.6) and therefore towards the transfer pipes (3) are connected to the double-shaft reducer (1.1). Therefore, when there occurs a problem in one of the titanium-boron reels, for example when one of the titanium-boron reels (5) runs out, the rotation speed of the double shaft reducer (1.1 ) is doubled via PLC program and feeding is performed and the other titanium-boron reel (5) is processed in order to perform feeding. Thus, the liquid metal may be continuously fed with the titanium-boron.

When all of the titanium-boron reels (5) are operable, the double-shaft reducer (1.1) decreases its rotation speed again and turns back to the normal operational speed. Two separate rotation systems which have been measured may be intermingled because there is double rotation monitor in the present feeding units (M) as is seen in Fig. 1. One rotation monitor (1.4) is connected to each feeding reel (1.2) located at the feeding unit (1). Through the rotation monitors (1.4), the speed of the double-shaft reducer (1.1) may be controlled, increased, and decreased by PLC.

There are diamond-shaped rhombus patterns on the surface of the feeding reel (1.2). These rhombus patterns of the feeding reel (1.2) increase the friction coefficient.

Meanwhile, by means of their gear structure having a specific form, the gear reducer (1.3) directing the titanium-boron rods to the liquid metal sends the titanium-boron rod (4) to the transfer pipes (3) that are full of liquid metal, without crushing them and by being kept at the axis.

Also, the system may be deactivated since deformations and locking cases occur in the reels (M5) which allow the titanium-boron rods to enter the movement groups properly as is seen in the present feeding units (M) seen in Fig. 1.

However, at least one pressure spring (1.7) is connected to each feeding reel (1.2) in the feeding unit (1) of the invention. When there is a deformation in any one of the components providing movement to the titanium-boron rods (4) such as a wear on the surface of the feeding reel (1.2) of the feeding unit (1 ) or when the titanium-boron rods (4) come from the titanium-boron reel (5) in a worn condition, the pressure springs (1.6) apply an upward pressure and prevents the seize and stopping problems which may occur due to said deformations.

The feeding unit (1) of the invention has two pressure springs (1.7), two gear reducers (1.3), two feeding reels (1.2), and two rotation monitors (1.4) being one for each feeding reel.

In the feeding unit (1) of the invention, the titanium-boron feeding to the liquid metal transferred from the aluminum melting and keeping furnaces is performed in a swifter and smooth manner.
