居龙钢铁批量配套改装厂自卸车生产，NM450耐磨板90度折弯加工，整板折弯成型平整美观，强度高，耐磨性强。

Julong Steel maintains close cooperative relationships with major steel mills, leveraging complementary strengths and sharing technology in the bending and processing of wear-resistant plates to continuously improve the formability of these plates.

居龙钢铁与涟钢保持紧密合作关系，在耐磨板折弯加工方面优势互补，技术共享，不断提高耐磨钢板的可塑性。

Bending wear-resistant steel plates at a 90-degree angle has long been a challenge in the manufacturing industry. To ensure that large quantities of bent parts maintain a 90-degree angle without cracking, Julong Steel has independently developed a perfect solution.

耐磨钢板90度折弯一直是加工领域一道难题，能保持大批量折弯件90度不断裂，居龙钢铁自主开发了一套完美的解决方案。

JULONG STEEL is currently capable of bending full-size sheets of various specifications up to 12 meters in length. We operate a 12-meter, fully CNC-controlled 4,000-ton press brake developed in-house, as well as a 12-meter, 2,000-ton LVD-HD press brake from Belgium, both equipped with specialized CNC systems from the Dutch company DELEM. German linear encoders provide real-time detection, feedback, and correction, along with full closed-loop control. The machines feature multi-step programming capabilities, enabling automated operation to complete multi-step parts in a single pass, thereby improving production efficiency.

居龙钢铁目前可加工12米以内各种规格整板折弯。我们拥有一台自主研制12米全数控4000吨折弯机和一台黄锻12米2000吨折弯机，都采用荷兰DELEM公司折弯机专用数控系统，德国光栅尺实时检测反馈校正、全闭环控制，具有多工步编程功能，可实现多自动运行，完成多工步零件一次性加工，提高生产效率。

In the cold-forming of wear-resistant and high-strength steel plates, JULONG STEEL has continuously developed a set of highly efficient and practical processing techniques that effectively address cracking issues during plate bending. The company provides custom processing services to clients both domestically and internationally, earning widespread recognition from its customers.
