Beloretsk Metallurgical Plant introduces incoming control of bearings

Beloretsk Metallurgical Plant (BMK AO, part of Mechel Group) introduces incoming control of bearings arriving at the plant. The facility acquired a laser scribing coder to trace the components placement and determine their lifespan.

Beloretsk Metallurgical Plant acquired this equipment as part of the program aimed at ferreting out bad-faith suppliers, reducing the expense of buying components and the volume of unplanned repairs, as well as controlling over efficient use of bearings at the facility.

Early this year the plant has already launched a certified test bench for examining and culling out low-quality bearings. During this time, over 3,000 bearings of various sizes were tested at the plant, with 13% of those rejected and returned to suppliers.

Installing a laser scribing coder at the incoming control department in the plant’s current equipment repairs workshop became the next step. It is equipped with special software, and marking one bearing takes 5 to 15 seconds. The laser inscribes its surface with the plant’s short name, date of arrival and item number. All this data, including information on when and where the bearing was installed, will be put into a special program developed by the plant’s IT team.

As a final stage, Beloretsk Metallurgical Plant plans to acquire a vibration data collector which assesses the bearings’ actual state while in use. This helps avoid their accidental failure and damage to their mating components.

“This program’s interim results have already demonstrated positive dynamics — if earlier this year we have rejected overall over 33% of all bearings we received, with the share of rejection on certain bearing types up to 80%, the latest testing showed only 13% of low-quality components. Thanks to our test bench, we manage to find out bad-faith suppliers and achieve a better quality of the bearings delivered to us,” Beloretsk Metallurgical Plant AO’s Chief Executive Officer Viktor Kamelin commented.
