BLAST FURNACE TROUGH MATERIALS AND TAP HOLE

The flow rate of molten metal and slag through the trough system increase many times in case of larger blast furnaces. To get good campaign life special attention must be given to both refractory lining and design i.e. trough geometry and cooling system. The trough design is based on fluid flow characteristics along with thermo-chemical reactions. Seven Refractories offer different lining solutions for your casthouse based on layout installation technique experience and user preference. Taphole clays. Seven Refractories taphole clay is the answer to Daily iron production of up to 12 000 t/d. Short intermediate tapping tap time 20 mins. Long operation on the same hole more than 20 days.

The basic setup of the plant is pretty simple slag is fed from the blast furnace tap hole through a slag runner and a vertical refractory-lined pipe. Entering the granulator it hits the center of a rotating cup is forced outwards and atomized. change the slag routes to the slag granulation l h d i Hot Metal Pot p ant or to t e ry p t Hot Metal Pot enables Prevention of a phreatic explosion in the slag granulation equipment.

RECOMMENDED GUIDELINE FOR IRON STEEL SECTOR

In the Furnace Hot Metal (along with slag) is processed from the raw materials. ii) Cast House In the Cast House Hot Metal slag are tapped from the Furnace tap hole and after flowing through a system of refractory lined troughs / runners flow into Hot Metal Ladles / Torpedoes Slag Pots placed on the iron slag Slag level on the opposite side of the tap hole is higher than at the tap hole and the mass of slag presses the hot metal surface below the level of the tap hole. Both hot metal and slag flow out through the tap hole until the slag level is so low that also gas can burst out. The tap hole is closed with a mud gun and the casting is over.

Hot metal and crude steel production stahl-online

Hot metal and slag gather in the lower area of the blast furnace and leave the furnace at a temperature of about 1500°C via a tap hole there (which must be opened). The hot metal and slag are separated via a refractory lined runner system and directed to the hot metal torpedo ladle and the slag ladle. Apr 15 2019 · It contains equipment for opening and closing of tap-hole and runners for flow of hot metal and liquid slag. Charge conveyorIt is the conveyor with steel cord rubber belt for taking charge materials to the furnace top from the stock house. Conveyor charging is alternate to skip charging.various materials such as sinter lime stone and coke

Importance of Hearth Dead man and Tapping in Blast

Apr 13 2016 · The tapping cycle starts with an outflow of iron only and slag starts flowing later when the slag-iron interface has descended to the taphole. After this iron and slag are drained simultaneously until the end of the tapping. The time elapsed from the start of the tapping until slag enters the runner is called the slag delay. Slag Arresting Dart Bulk density of this item is so designed that success rate is high and thus effectively arrest slag from going into the ladle during tapping of steel. Hence makes possible to tap Clean Steel and increases the useful capacity of steel ladle.

A Study of Slag/Metal Equilibrium and Inclusion

A Study of Slag/Metal Equilibrium and Inclusion Characteristics during Ladle Treatment and after determinations of bearing steel grade samples from a runner system after ingot casting were performed using a 2D metallographic method (CS-method). Also the After reaching the desired tap temperature the liquid steel is tapped into a ladle The blast furnance route so called integration route is still the most significant method in order to produce pig iron. Most possible service life of the blast furnace shaft linings as well as runner systems short repairing times and full-service solutions. These are the goals of BEKA

Hence makes possible to tap Clean Steel and increases the useful capacity of steel ladle. The piercing of the tap hole to remove the pig iron is called tapping. Together with the remaining slag the pig iron is then passed to the casting hall via a runner system in the floor. The slag is separated by specially guided line systems. The draining of liquid pig iron at regular intervals is referred to as tapping

system " said Carson Swartz Operations Supervisor for Tervita. "But the storage and cooling area was a big issue. Whether offloading churning or moving the slag to the crusher it s constantly being disrupted causing a lot of dust." Prior to installing the DB-60 the company tried using the This paper proposes an improved gating system design for casting process using experimental and simulation studies. The principle motivation behind optimization of gating system is to overcome the defects like shrinkage gas porosity slag inclusion cold shuts and misruns etc. Four different designs having different sprue location and runner cross-sectional area are taken into considerations

Slag Granulation with Continuous Dewatering Ironmaking

Slag Granulation Area Granulation Tank Blowing Box The slag granulation area links the hot slag runner of the blast furnace and the INBA dewatering system. This link is directly accomplished through the use of a granulation tank. The granulation tank creates a compact layout which allows a reduced water circuit design with op- Reduce Hearth and Taphole area wear by maintaining a consistent Taphole length. Specialised grouting products reduce crack propagation. Maintain uniform cast times by providing consistent iron and slag erosion and corrosion resistance. Minimise Taphole spraying during reduced cast-to-cast intervals.

A short history of the development of tapping equipment

perform hard and heavy manual work close to runners and ladles filled with hot liquid metal and slag. Before the invention and installation of tapping equipment the tap-holes were opened and closed manually. Opening was done by means of steel bars and sledgehammers whereas the tap-hole was closed by repeatedly ramming small The piercing of the tap hole to remove the pig iron is called tapping. Together with the remaining slag the pig iron is then passed to the casting hall via a runner system in the floor. The slag is separated by specially guided line systems.

The blast furnance route so called integration route is still the most significant method in order to produce pig iron. Most possible service life of the blast furnace shaft linings as well as runner systems short repairing times and full-service solutions. These are the goals of BEKA Slag and iron overflow the side of the trough at their designed points and are channelled via a runner system to either the granulator for slag or the torpedoes for iron. With the high production targets at the blast furnaces in Vanderbijlpark Works a full pool practice is easily sustained.
