Steel industry
As a key pillar of the national economy, China’s steel industry is comprehensively advancing equipment upgrades and supply-chain self-reliance, with the metallurgical lubricant sector gradually achieving import substitution. As a pioneer in domestic lubrication technology, Derunbao’s product line has been deployed at scale by leading enterprises such as Baowu Group, Taishan Iron & Steel, and Shiheng Special Steel, enhancing equipment reliability and optimizing operation‑and‑maintenance costs, thereby continuously supporting the steel industry in reducing costs, improving efficiency, and pursuing high‑quality development.
Metallurgical lubricants and greases are the “lifeblood” of continuously operating steel‑making equipment. Their applications span critical components such as rolling mill bearings, dry‑oil lubrication systems, centralized lubrication systems, open gears, wire ropes, and the sector rolls of continuous casting machines. Operating under extreme conditions—prolonged exposure to high‑temperature radiation, heavy‑load impacts, water‑borne erosion, ingress of iron oxide scale, and continuous, uninterrupted production—these lubricants demand exceptionally high performance in extreme‑pressure and anti‑wear properties, high‑temperature stability, water resistance, corrosion protection, pumpability, and long‑term reliability. Any lubrication failure can result in bearing seizure, roller‑line blockages, excessive gear wear, or even unplanned shutdowns of the entire production line, leading to economic losses of hundreds of thousands of yuan per minute and posing significant safety risks—making these lubricants especially critical in continuous, automated manufacturing environments.
