On September 13th, 2014, the hot on-load test at double treatment positions of the 120t RH Refining Furnace Project for Tianjin Rockcheck Group of the 120t RH Refining Furnace Project was successfully performed at one time.

As the supporting project for 1mtpa Precision Alloy Steel Bar Production Line of Tianjin Rockcheck Group, it supplies high quality liquid steel for the following round billet continuous casting, then further supplies high quality billets for the precision bar production line. This project was contracted on turn-key basis covering engineering, equipment supply, installation, commissioning, cold integrated test, technical personnel training and site startup instructions of a 120t RH refining furnace with double treatment positions.

The project was engineered in “three cars and five working positions” form with average treatment cycle less than 30 minutes and 1.4mtpa processing capacity of liquid steel. Under the consistent quality control over hot metal pretreatment, converter, RH furnace and continuous casting, the quality will meet the standard [C]≤15ppm and [H]≤1.5 ppm. The pumping capacity and time cost of the vacuum pump has reached and even outperformed the designed indexes. The overall mechanical performance and process indexes reach the world leading level, wining high appraisal from the client.
