METALLURGICAL ENGINEER

Twenty+ years experience in Metallurgical engineering, including:

. Melt shop with duplex EAF/AOD process;

. Research in a continuous casting technology;

. Metallurgical testing laboratory;

. Mini mill (carbon plate producer) with EAF and one strand

continuous slab caster.

Track record of translating business needs into solutions that

contribute to time and cost savings, risk reduction, profitability,

customer satisfaction. Ethical, innovative, and effective.

Professional Experience

EVRAZ CLAYMONT STEEL, Claymont, DE 1998 to 2013.

Metallurgical Engineer - Responsible for Quality improvement and

Production support,

as well as for conducting projects

and services for the Melt Shop and Plate Mill.

. Initiated and followed-through the chemical composition changes for

HSLA grades such as A572, A588, A656 with positive results in yield:

> reduced loss during slab conditioning by 10%-15%;

> reduced plates rejection by 5%-10%;

> reduced low temperature impacts failures by 50%.

. Developed and implemented a control rolling practice to achieve

required mechanical properties on a grade A65680.

. Suggested and developed a practice for using Nitrogen bearing

Vanadium, which reduced consumption of Ferro Vanadium by 10%-15%.

. As of a team, solved a nozzle blockage problem at the caster.

. Developed new slag practice in EAF, which reduced refractory wear by

5%.

. As part of a team, developed and implemented water quench practice

of continuously cast slab before unbending which improved slab

surface quality and reduced loss during conditioning by 0.5%-1.0%

ELGILOY SPECIALY METALS, Elgin, Il 1994 to 1998.

Metal Material Analyst - Responsible for quality assurance and

delivering material related problems solutions to a

wide range of customers in the metallurgical testing

laboratory.

. Provided quality control for cold-rolled and annealed strip of high

performance Ni-Co-Cr based materials and A286, 17-7, AM350 type

steels, Stainless Steel and titanium alloys;

. Provided evaluation of mechanical properties, tensile and hardness

tests, and microstructure characterization, to assure adherence to

AMS, ASTM, GE specifications, as well as to customer-particular

specifications;

. Proposed and designed step-by-step laboratory procedure for complete

material testing sequence, based on specification requirements.

Implemented procedure significantly sped up the required tests and

increased the efficiency of the laboratory by 25%;

Professional Experience

Metal Material Analyst (continued)

. Conducted and completed research project on carbide precipitation

mechanism in the 304 type stainless steel, resulting in development of

better heating and cooling profiles that eliminated carbide precipitation

in the grain boundaries.

. Developed a new technique of sample preparation than reduced the total

time of analysis.

. Developed a method of improving mechanical properties of titanium

Ti40 (titanium grade 2) using Ti25 (titanium grade 1) as a base

material. This method contributed to an increase in profit margins

by 5% for the plant by using a more flexible approach for

purchasing.

RESEARCH INSTITUTE OF STEELS AND ALLOYS, Zaporozhye, Ukraine 1991 to 1994

Senior Metallurgical Engineer - Responsible for research and development

of a new mold powders for continuous casting,

using recycled slag.

. Developed powders resulted in 10% price reduction and an improved

manufacturing environment.

. Worked on implementation of a new method of improving the internal

structure of continuously cast slab.

DNEPROSPETSSTAL, Zaporozhye, Ukraine 1987 to 1991

Production manager - Responsible for managing an AOD shop. Specialized in

stainless steel.
