the Blast furnace production of cast iron CMP provides for the subsequent production of steel. Overhaul of blast furnace no. 4 started in July 2019. The builders completely dismantled the old equipment, put together a new casing and cupola furnace, replaced the refractory brickwork, the system of refrigerators, and also assembled a new system of gas purification. The system is completely sealed and prevents the ingress of combustion products into the atmosphere. Formed in the steelmaking process blast furnace gas is then used as fuel. In the gas cleaning system is separated from impurities through a network of pipelines served to consumers: CHP and other departments of the enterprise.
At the end of the repair to the furnace was installed new device for the filling of iron ore and coke. In the construction used high-temperature carbon concrete and refractory brick produced in Russia, and also carbon blocks for the base of the blast furnace.
the blast furnace is Also equipped with a modern automated control system. All the parameters of operation of the furnace will be controlled by a computer and displayed on a single monitor.
"All repairs have been completed. We are starting a cold purge of the furnace to identify and eliminate possible leaking areas. Blast furnace will be put into operation with the commissioning of the new Converter, installation is in progress in the BOF shop," said chief engineer of JSC "CHMK" Vladimir Kapnin.
background: the performance of the blast furnace – more than 1 million tonnes of pig iron per year (about a quarter of all produced by CMP of cast iron).
