Realize domesticization!This steel we produce breaks foreign monopolies

On August 25, good news came from the Laiwu Branch of Shangang Co., Ltd., after unremitting technical tackling, after multiple rounds of rigorous and thorough trials and industrial chemical tests, 317 single -tooth track steel, known as "the highest difficulty in history" Finally, it was successfully trial -made at the Laiwu Branch Laiwu Branch.

Due to the extremely asymmetric cross -section, the single -tooth track steel is the most difficult track steel variety in hot rolling difficulty. The maximum specification of a single -tooth tape steel 317 specification track steel is even more "difficult." 317 Specification Steel is often used in oversized tons of construction machinery manufacturing. At present, a global European company can produce and monopolize the market's right to speak.

In order to promote the domestic development of the 317 single -toothed tape steel, Shan Steel Co., Ltd. Laiwu Branch Technology Center Joint Steel Factory, Special Steel Division, Marketing Corporation and other units visited users several times to conduct technical tackling. The section -type steel hot rolling process is finally successful.

The 317 single -tooth track steel labeling "Yam Steel" label not only achieves a breakthrough in the hot -rolled technology of the largest single -tooth tape steel steel in China, breaks the foreign monopoly technology, solves the dilemma of dependence on imports, and is also a large tonnage engineering machinery in my country. Independent innovation development provides important steel materials support.
