Coke Oven Flue

Temperature measuement by a maintenance engineer
  Temperature measurement of the Coke Oven Flue provides vital information on the condition and efficiency of the oven battery. The life of the oven, the quality and quantity of the throughput are all related to the balance and temperature levels in the heating chambers.

Recommended System:-
Portable Infrared Thermometer Cyclops 100 + Datalogger

Coke Oven

Coke Oven Profile
  Efficient operation of coke ovens is dependent on flue temperatures and temperature profile. A direct measurement of oven wall temperatures is most beneficial and can now be achieved by utilizing specially designed Fibroptic radiation thermometers, complete with light guides up to 33 meters/108 feet in length, installed at various positions on the pusher arm.

The thermometers track across the length of both walls of the oven as it is pushed to produce a complete temperature profile.

Recommended Systems:-
On - line infrared Thermometer System 4 - M1 Fibroptic - contact LAND
Stand alone infrared thermometer UNO - U1 Fibroptic - contact LAND

Top of page3 - Coke Oven Burden
Coke Oven Burden   An extremely efficient, automated method of obtaining the Coke Oven Heating Profile is to measure the temperature of the coke burden as it is pushed from the oven. The oven profile can then be inferred from the temperature of the coke.

Recommended Systems:-
On - line infrared Thermometer System 4 - M1 - contact LAND
Stand alone infrared thermometer UNO - U1 - contact LAND

Top of page4 - Coke Conveyor
Coke Conveyor   Monitoring the coke on the conveyor helps to prevent over and under quenching and provides coke conveyor protection so that it can be safely transported to the blast furnace without the risk of reigniting and damaging the conveyor belt, with the consequent loss of production.

Recommended Systems:-
Conveyor Protection System - LSP
Stand alone infrared thermometer - RT8A
On - line infrared Thermometer System 4 - M6

Stand alone infrared thermometer UNO - U1
Stand alone infrared thermometer - RT8A

Stage 2 - Blast Furnace
Stage 2 - Blast Furnace Hot Blast Stove Hot Blast Main Blast Furnace Burden
Top of page6 - Hot Blast Stove
Hot Blast Stove   Hot Blast Stove operation is optimised, best performance versus life. Monitoring the temperature of the refractories safeguards against damage and maximizes the production rate of blast furnace iron.

Recommended System:-
Stove Dome Assembly
On - line infrared Thermometer System 4 - M1
Stand alone infrared thermometer UNO - U1

Top of page7 - Hot Blast Main
Hot Blast Main   The temperature of the gases passed through the Hot Blast Main significantly affects the efficiency of the blast furnace operation. Gas temperature, inferred from a target block, provides continuous on-line data on the furnace campaign.

Recommended Systems:-
On - line infrared Thermometer System 4 - M1
Stand alone infrared thermometer UNO - U1
Top of page8 - Blast Furnace Burden
Blast Surface Burden   Measurement of Blast Furnace Burden temperatures provides information on patterns of blast furnace behaviour. It is a useful research tool in support of mathematical modeling.

Recommended Systems:-
On - line infrared Thermometer System 4 - R1
Stand alone infrared thermometer UNO - V1

Top of page9 - Liquid Iron Stream
Liquid Iron Stream   A continuous record of liquid iron temperatures is required during the tapping cycle. It provides an indication of furnace operation and can be used for a rapid estimate of silicon content.

Recommended Systems:-
On - line infrared Thermometer System 4 - M1, M05
Stand alone infrared thermometer UNO - V1



Stage 3    
Stage 3 - Torpedo Car
Top of page10 - Torpedo Car
Torpedo Car

Regular temperature monitoring of the outer shell minimizes damage and maximises efficiency.
  The Torpedo car is internally lined with protective refractory bricks.
During continuous use the refractories can wear extremely thin and heat from the liquid metal may cause a breakout.
Regular temperature monitoring of the outer shell minimizes damage and maximizes efficiency.

Recommended Systems:-
Infrared linescanning systems - Landscan, Ladle Safety System
On - line Thermal Imager - FTI6

Literature downloads are available on the LSP6 Series (187KB).
Stage 4    
Stage 4 - Ladle
Top of page11 - Ladle Pre Heat
Ladle Pre Heat   Ladles are pre heated in order to avoid damage to the refractories by thermal shock from the molten metal. A thermometer is mounted on the portable lid to monitor the temperature of the refractory lining during the pre heat process.

Recommended Systems:-
On - line infrared Thermometer System 4 - M1
Stand alone infrared thermometer UNO - V1

Ladle

Information that can be used to avoid excessive lining damage
  Maintenance of the refractory lining is a significant contribution to the cost of steel production.
Monitoring the external temperature pattern of ladles using a thermal imager allows the extent and distribution of wear to be assessed.
This information can be used to determine relining strategy and avoid excessive lining damage and breakouts.


Recommended Systems:-
On - line Thermal Imager - FTI6
Portable Thermal Imager

13 - Tapping
Tapping   A thermographic Slag Detection System (SDS) is used to monitor the molten steel as it is poured from the BOS vessel. The SDS produces a thermal image, which readily enables the detection of slag. Although the molten metal and the slag are roughly the same temperature the high emissivity of the slag makes it appear hotter in the image and hence, easily detectable.

Recommended Systems:-
Slag Detection System - SDS
