Recently, the RMHS phase 1 step 1 project of new and old kinetic energy conversion project of Shandong Iron & Steel Group Laiwu Branch, which is generally contracted by our company, is going on smoothly and successful in the commissioning, charging and production. 

The RMHS phase 1 step 1 project is the raw material and fuel conveying line built up to ensure smooth commissioning of the new 1#3800m3 BF built by Laiwu Branch, and shall convey coal, lump ore, pellet ore and other ore materials for 1#3800m3 BF, and shall provide important raw material guarantee for the smooth start-up, commissioning and operation of the BF.

The RMHS phase 1 step 1 project includes main control building 35kv substation, 1#truck receiving & unloading room, integrated transfer station, SX5 transfer station, and dedusting system for the truck unloading and integrated transfer station. The major equipment includes 2 sets of 35kv transformers, 4 sets of 10kv transformers, 9 belt conveyors, 12 sets of feeders, as well as related supporting facilities such as electric, instrument, water supply & drainage system, thermal power, fire protection, and etc. It is a highly intelligent and green environmental protection production line built under the concept of "Intelligent manufacturing and green development" of Shandong Iron & Steel Group. Among them, the truck receiving & unloading is the most important method of receiving & unloading, and 1#truck receiving & unloading room has totally 12 receiving hoppers including 5 hydraulic unloader receiving hoppers and 7 dumper receiving hoppers. The injection coal for BF and coal for sinter plant shall not share the receiving hopper with other ores. The designed charging capacity of coal is 1800t/h, and of ores is 2000t/h, which can completely satisfy the charging requirement for 1#3800m3 BF.

At present, the RMHS phase 1 step 1 project has been running smoothly for more than 20 days. It can supply 2500t coal, 1200t lump ore and 2000t pellet ore for 1#3800m3 BF every day. Up to now, totally more than 50,000 tons of materials have been conveyed to the BF. It provides sufficient raw materials for the stable production of BF and lays a solid foundation for the smooth development of follow-up projects.
