Business Scope:3050 m³ BF, PCI for 2 sets of 1500 m³ and 1 set of 2500 m³ BF, 5# and 6# coke ovens, 3.2 MT sinter.

BF

All BF systems, excluding pig casting machine and TRT system. New technology and new equipment contracting mode is adopted.

• New type serial hopper bell less top
• Full stack cooling stave structure, and high heat load area adopting copper cooling stave.
• Combined structure of ceramic cup and carbon brick
• BF proper and hot blast valve adopts integrated softened water cooling.
• Stock level monitoring device in furnace.
• Advanced and reasonable cast house type and intensified dedusting technology in tap hole area.
• High temperature long life time external combustion HBS technology.
• New type INBA slag granulating and treatment system
• Coke nut and sinter of small grain size recovery, fume waste heat recovery and other energy saving and consumption reducing technology.

Coke oven

The 5# and 6# coke oven project of ISDEMIR in Turkey is the first large coke oven export project undertaken by the company in form of EPC. The annual design production capacity of coke by the 2 sets of coke ovens is 1.3 MT. the contracts for the coke oven project general contracting and the coke oven machinery project are signed respectively in June and July 2004. Start-up is effected and coke produced for the two sets of coke ovens respectively on October 27 2007 and November 30, 2007, and performance test and acceptance test are successfully passed on May 10, 2008. on November 15, final acceptance is smoothly passed by the owner for the coke oven project.

PCI

General contracting for PCI projects for 2 sets of 1500 m³ BF and 1 set of 1500 m³ BF. On November 18, 2008, the company got the PCI project for 1# (1500 m³), 2# (1500 m³) and 3# (2500 m³) BF of ISDEMIR Steel Plant in Turkey. The PCI project for the BF in Turkey is the first large BF PCI project undertaken by contracting by the company. The company is responsible for engineering design, equipment supply, technical service and production instructions to BF operation and PCI operation. With hard working of the technical personnel and project management personnel of the company, the project is successfully started up on November 15, 2007 and final acceptance is smoothly passed by the owner on September 1, 2008.
