Iron & Steel Industry Solutions

An integrated iron-steel facility is one of the world's most complex industrial complexes. Raw material flow includes the following main lines:

• Ore line — iron ore, limestone, dolomite arrive at the site from the port or mine; transported by belt conveyors to the stockpile hall; from there distributed to sinter and blast-furnace feed.

• Coal and coke line — coking coal is processed at the coke plant; produced coke is conveyed to the blast furnace.

• Sinter line — a mixture of fine ore, coke and limestone is sintered and charged to the blast furnace.

• Blast furnace charging — charge materials (ore + coke + lime) are loaded into the furnace at precise dosages.

• Slag and waste lines — slag at the furnace outlet is conveyed by a separate line, either recycled or disposed of.

TMD GRUP manufactures the mechanical infrastructure of each of these lines.

Iron-steel facilities have the highest-tonnage lines in industry. A blast furnace consumes thousands of tonnes of raw material per day; this creates the need for conveyors at 1,600 mm and 1,800 mm belt-width levels.

The TMD-BC-1600 and TMD-BC-1800 models directly answer the high-capacity demand of the iron-steel sector. The design features used on these lines:

• Heavy steel-construction chassis — vibration and tremor resistance.

• High-strength belt (steel-cord reinforced) — for long-distance and inclined runs.

• HB450 abrasion-resistant steel housings.

• Large-diameter drive drums and reinforced bearing groups.

• Automatic take-up — absorbs thermal expansion and load variations.

These conveyors are also the largest sizes of our catalogue's foundational TMD-BC series.

In iron-steel production, temperature is always high. Sinter outlet can be 100-300°C, coke cooling outlet 70-150°C, furnace slag at 700-1000°C levels. Standard equipment cannot operate at these temperatures — custom manufacturing is required:

• Heat-resistant belt types (heat-resistant rubber, EPDM) — up to 150-200°C range.

• Steel-mesh belt conveyors — for applications above 300°C in place of rubber belts.

• Heat-resistant bearing and roller sets — for high-temperature steel components.

• Cooling lines — cooling the belt or bucket via water spray / air flow.

• Expansion compensators — flexible connections that absorb thermal-expansion differences.

These custom designs are calculated separately for each project; they fall under TMD GRUP's custom engineering scope.

In iron-steel facilities, not only conveyors but also large-scale steel constructions such as furnace-surround support structures, charging towers, gas-cleaning structures and walkways are needed. TMD GRUP manufactures heavy steel construction under EN 1090 EXC3 certification — the highest execution class for structural steel production in Europe.

Our manufacturing capacity:

• Up to 50-ton single-piece production.

• 3000 × 12000 mm CNC plasma cutting — large steel plate cutting.

• MIG / TIG / SAW welding — WPS/WPQR certified operators.

• NDT inspection — verification of weld quality.

• Powder-coat preparation and electrostatic coating line.

This capacity allows us to offer single-source solutions to our iron-steel customers — conveyor + support structure + installation.

Sinter plants and pellet plants are the most mechanically-intensive sections of the iron-steel complex. Fine ore, coal and additive materials must be precisely dosed, mixed, sintered and then screened/classified.

Equipment TMD GRUP manufactures on these lines:

• Raw-material feed belts — dosing belts (load-cell integrated).

• Mixer-feed conveyors (sequence matters — coal, ore, limestone etc. in correct ratios).

• Post-sinter cooling belts.

• Multi-deck vibratory screens — sinter or pellet classification.

• Undersize return belts — return to the milling line.

The design of these lines typically falls under custom engineering as each facility has its own unique flow sheet.

The iron-steel sector is historically a sector with high emission potential: ore dust, coke dust, sinter dust, casting dust can all escape into the atmosphere. European and Turkish environmental regulations tightly monitor this sector.

TMD GRUP provides emission control to iron-steel customers through a combination of bag filter systems and rotary feeders:

• Local dust extraction units at stockpile halls and transfer points.

• High-temperature-resistant (Aramid/Nomex) filters at sinter outlets.

• Coke-plant ventilation systems.

• Rotary feeders and screw conveyors for recovering collected dust.

These systems keep atmospheric emissions below legal limits and meet the sector's licensing requirements.

Iron-steel projects are TMD GRUP's largest-scale work. A blast-furnace belt conveyor line contract can run several months; site installation can extend from a few weeks to a few months. For this reason the customer relationship requires project-management discipline:

• Detailed project planning with MS Project or Primavera.

• Monthly progress reports and regular coordination meetings.

• Joint engineering with the customer's engineers during the design phase.

• Openness to customer inspection during manufacturing (FAT — Factory Acceptance Test).

• Integrated work with the customer team on site (SAT — Site Acceptance Test).

• Long-term spare-parts and technical-service agreement.

This discipline minimises surprises in a high-stakes sector like iron-steel.
