Coke Ovens
For more than 30 years, FIBS has been providing coke plants with technologies dedicated to the PREVENTIVE MAINTENANCE and CURATIVE REPAIR of the refractories of coke ovens, as well as a unique process for the REDUCTION OF AIR EMISSIONS (cross leakages). These technologies have been fully in house engineered.
A Comprehensive Maintenance Plan including Inspections, Ceramic Welding, Gunning, Microcracks Sealing, Charging Holes / Ascension Pipes Sealing, Door Sealing and Related Activities will ensure environement-friendly operations.
FIBS techniques are suitable for BY PRODUCTS (VERTICAL) or NON RECOVERY COKE OVENS
Ceramic Welding
Ceramic Welding process of FIBS has been self-developed in the early 90's. This process is now accepted by the industry as one of the most performing process thanks to :
Machine & Equipments
Small & Light / Safe
Simple & Easy Maintenance
Low/High Flow
Lances From 1 to 11 meters
Only Oxygen
(No Air, Nitrogen, Electricity, Pressure)
Low Maintenance
Low Spare Parts Cost
Surface Preparation
Preparation of the surface to be welded is one of the most important step of the ceramic welding repair.
FIBS offers 2 methods of Surface Preparation
Sandblasting
Pneumatic Hammers
Materials
Materials Suitable for each specific repairs :
Standard Silica Repairs
Low Temperature Repairs
Chamotte/Alumina Repairs
-
For Sole Flues, Lintel Area, Door Jamb Bricks, Heating Wall, Watse Gas Box, Renegerators, Sole, Charging Holes

Liquid Dusting for the Reduction of Air Emissions (Microcracks Treatment) : RPR SL
Air emissions and environmental care are to be considered as an important factor of the coke production.
Air emissions due to the coke production process have various origins, among them the cross leakages between the coking chamber and the heating flues. When the leakages are below 2 mm, it is very difficult to close them individually with ceramic welding. FIBS has engineered an genuine process that allows the global sealing of microcracks up to 2 mm.
The process consists in the pulverization of approximately 2 liters of liquid material (it is not a waterous suspension of silica) in the coke oven chamber. The material will ignite and create a cloud of new silica particles (amorphous = no risk for health) that will be pushed by the pressure release of the reaction through the cracks until complete sealing of the coking chamber. The application takes only 5 minutes
Main advantages
-
No risk for silica disease
-
Quick and easy
-
More efficient than silica dusting
-
No deposit on the flue bottom
S-Bricks
The application of S-Bricks is a quick and cheap solution to the hot repair of major damages.
It can be applied for :
-
End Flue Repair (full height) : possible to repair 1st and 2nd flues even for tall ovens
-
Flues Repair (partial) after cleaning of the heating flue bottom
-
Flues Repair (partial) deeper in the coke oven chamber
Glass Coating (RPR GC)
RPR GC (Glass Coating) is a very specific grade of ceramic welding material especially developed to prevent a strong and deep anchorage of carbon in the refractory lining of the coke oven. This material can be applied in :
-
The charging hole area
-
The Upper part of the chamber
-
The ascension pipe and the goose neck
Endoscopy
FIBS has developed its own endosopic equipment in the prupose of assistance during the repairs in the middle of the ovens, or in the heating flue. This Equipment can also be used for the monitoring of heating flue, gas gun, regenerators, and channels.
Expertise, Technical Assistance and Training
FIBS has set up an expert team with long-experienced coke plant operators/managers, ceramic welding specialists and refractory specialists. This team is able to :
-
Train and assist contractor (ceramic welding, best practice for maintenance, refractories, etc.)
-
Assist the coke pant with solving problem, implementation of a maintenance programm, adjustment of production parameters, etc...
-
Provide any other audit and survey service (conditions of the ovens, recommendations, etc.)
FIBS' specialists have already trained, certified and assisted more than 350 ceramic welders in more than 25 different countries !
