BSEW conceives minimills and integrated plants with a compact layout, where the whole steel production process takes place, starting from scrap melting in the Electric Arc Furnace, proceeding through continuous casting and ending with product rolling and finishing. These arrangements simplify organization and raw material transportation, allow production flexibility and reduce logistic costs for final product distribution.
Product range:
ROUND AND DEFORMED BARS: from 6 to 40 mm dia.
WIRE ROD: from 5.5 to 20 mm
ANGLES: from 25 x 25 to 60 x 60 mm
CHANNELS: from 35 x 15 to 60 x 40 mm
TEES: from 25 x 3 to 50 x 6 mm
FLATS: from 30 x 5 to 80 x 30 mm
STARTING MATERIAL: billets up to 160 mm Sq 12 m length
The layout mainly consists of:
MELTSHOP and CONTINUOUS CASTING MACHINE
- Supply of ultra-high power EAF with EBT bottom tapping system.
- Semi-automatic EAF tilting system allowing safe checking of furnace tapping.
- Modern EAF / LF Electrode Control System for furnace operation and melting control optimization, to improve energy efficiency.
- Level 2 automatic EAF melting process control.
- Efficient and powerful dedusting systems for the treatment of EAF and LF off-gases during scrap melting and steel refining, fulfilling the strictest environmental requirements, aimed at energy consumption reduction and at attaining improved working conditions in the melt-shop.
Level 1 and Level 2 automatic CCM speed casting and secondary cooling control.

LONG PRODUCT ROLLING MILLS
BSEW rolling mills are the result of the joint efforts of an engineering department with a longstanding experience in this field. Our highly skilled professionals cover the whole plant development, from billet heating in the reheating furnace, to long product rolling and packaging in the finishing area.
BSEW provides full rolling mill design, manufacturing and commissioning and can create customized machines which can meet any kind of requirements, finding the best specific solution and adapting to special needs.
BSEW rolling mills for long products feature:
– High equipment reliability
– Wide range of product sizes
– Highest allowable material yield
– Low transformation costs
– Low spare parts costs
– Low maintenance/set up production down time
– Higher quality on finishing products
– Shortest equipment delivery/erection/start up time
FINISHING AREA
BSEW rolling mills for rebar, medium sections, wire rod and special steels feature fully equipped areas for rolled stock finishing after quenching and tempering for rebars, or thermal treatment for rounds and wire rod. After being cut by the dividing shear, the product enters the finishing area.
BSEW can supply apron type discharging or twin channel system on cooling bed for rebar, rounds and sections, laying head and conveyors systems for wire rod. According to the kind of rolled stock, the BSEW finishing line is completed by different machines for product bundling and packing: bar counting device, bundling and lowering units, stacking units and controlled cooling lines, trestle carousels, tying and strapping machines and other equipment.
