Dummy bar

Dummy bar for the continuous casting machine is used to start a continuously cast steel strand. DDMET could design, manufacture and supply all kinds of rigid dummy bar and flexible dummy bar.

The rigid dummy bar is curved and has a radius equal to the casting radius, includes a dummy bar head. The flexible dummy bar is made up essentially of pivotally connected, mainly used in the slab continuous casting machine.

Feature of DDMET’s dummy bar:
1.    Higher quality;
2.    Less maintenance;
3.    High efficient;
4.    Simple structure;
5.    Longer service life;
6.    Easily on operation;
7.    Design/fabricate completely according to original drawing;

Besides the dummy bar, we also manufacture and supply following equipments and spare parts:

DDMET complete line of equipment supply includes:
Iron and steel smelting equipment, 
Continuous casting equipment, 
Rolling equipment, 
Metallurgical auxiliary equipment and environmental protection equipment

DDMET consumable spare parts:
copper mould assembly, copper mould tube, copper mould plate 

Dummy bar is the early stage of slab production. It is a chain type which requires high technology in processing.
 
Supply billet, round and slab sized continuous casting machine and related spare parts. Size range from 60mmX60mm to 700mmX700mm for billet CCM, fromΦ80mm to Φ900mm for round CCM, and from 120mmX850mm to 3600mmX1000mm for slab CCM.
 
The characteristics:
·Ladle turret: Straight arm type, with automatic weighing device, emergency driven unit and driven by electric motor.
·Tundish and tundish car: Two options are gantry type tundish car and cantilever type tundish car. For the gantry type, it’s safe and reliable, but there is some limit on operator’s vision. For the cantilever type, it can be moved faster and give the operator good vision.
·Copper mould assembly: It’s the heart of continuous casting machine, and we adopt the most advanced European technology. The products are used by well-known steel mill both at home and abroad.
·Mould vibrating device: Mechanical type and hydraulic type. For mechanical type, the cost would be reduced compared with hydraulic type. For hydraulic type, it’s reliable and easy for maintenance.
·Dummy bar: Rigid type or flexible type. For rigid type, it’s safe and reliable, but it takes much space. For the flexible type, the structure is simple and less area occupied.
·Withdrawal and straightening device: The straightening process adopts the gradually straightening technology. The rollers are driven by three-ring reducers and hydro-cylinder. 
·Cutting device: Two options are flame cutting type and hydraulic shear type. For the flame cutting, the weight of the device is light, and with no limit on the billet size. For the hydraulic shear, it’s efficient and lower loss.
·Electric control system: This system uses Simens PLC control scheme, carrying on the surveillance by a computer.
 
At beginning of casting,dummy bar will reach out from storage position,via withdrawal stragihtening machine & insert into mould
Dummy bar is used in continuous casting machine. It is used to guide the billet.
 
 
Application: The dummy bar is used to tract and lead the cooled and solidified strand and pull it out by the withdrawal and straightening machine.
 
Features: In order to avoid the deformation of dummy bar body due to heating, the dummy bar is equipped with a cooling water pipe inside the bar body. It has the featuress of smaller deformation, long service life, simple structure and installation, easy operation and maintenance.
