OREANDA-NEWS. Metinvest completed testing of high-strength and wearproof plates for lining the body of BelAZ dump trucks at Central GOK.

Performance testing of 16ХGМPHTR and 25ХGSR grade plates had been underway for 18 months. The results showed that wear and tear on the loading platforms' lining was reduced by three times on average. Due to the use of high-strength rolled products, the service life of dump truck lining will increase by 1.5 times and the costs for relining will be 30% lower.

High-strength and wearproof plates are used for mining equipment, elevating mechanisms and hoisting cranes and in construction industry. High-strength rolled products are manufactured according to the "quenching and tempering" technology. It has many advantages compared to commercial steel grades (for example, 09G2S with 355 MPa strength class). Performance characteristics of structures and different products are improving: their service life and load-carrying capacity increase, while metal consumption and production costs decline.

Pavel Timoshenko, Central GOK's general director:

"In the coming years, our main efforts will be focused on the growth in the production efficiency. Use of high-strength rolled products will allow us to reduce substantial costs for replacing the lining of BelAZ bodies. We are planning to continue testing high-strength rolled products on different equipment that is subject to heavy wear: bulldozer blades and excavator buckets."
