System combines the advantages of 100% scrap preheating and continuous scrap feeding through its chambers, without the need of EAF roof opening. EPC prevents totaly, any dust emission and heat loss during furnace charging stage, as it is the case normally for other operations. The EPC-EAF is a new generation, economical and environmentaly friendly Electric Arc Furnace. Considerable reduction in electric energy consumption, increased productivity, meeting strict environmental regulations, less dust load within the melt shop, flicker reduction& harmonic disturbance reduction are some of the important features of the new and superior EPC system.

  • 4. KR Tec C O M PA N Y   P R E S E N TAT I O N  CVS headquarter is placed in the industrial region of Gebze, just east of Istanbul, close to many major ports  Our modern facilities consists of more than 50,000sqm 50 000sqm of closed area and a land of additional approx. 50,000sqm  CVS workforce is formed by over than 750 specialized workers and engineers with a modern machinery park to undertake even the most challenging projects. g gp j  Over than 270 engineers and administrative employees are involved in the design and management of the projects.
  • 5. KR Tec EPC SYSTEMCVS MAKINA has a cooperation with KR Tec company which has developed a NewGeneration concept in Arc Furnace Steelmaking, ENVIRONMENTAL PREHEATING &CONTINUOUS CHARGING SYSTEM (EPC).Idea behind the challenge is to recover the heat lost to FTP system by the application ofScrap Preheating.The EPC System combines the advantages of thepreheating efficiency of the chamber and thecontinuous scrap feeding feeding.The EPC System is a new generation of economicalarc furnace furnace.EPC system overcomes all the missing items of theexisting Preheating system.
  • 6. KR Tec EPC SYSTEMOne of the issues of the EPC System is to charge the scrap independent of the electric arc furnacetaken into consideration the environmental aspects.The EPC System is installed beside the EAF and the preheated scrap can be charged continuously bythe telescopic feeder system in the melting chamber during Power On.Even during charging of the scrap basket into the EPC System, the system is always airtight and asmall amount of dust can only escape. Furthermore, the design has been considerably simplified toincrease the reliability and the profitability of the investment, reducing the ROI by less than 12months.
  • 7. KR Tec A D VA N TA G E SENERGY SAVINGENERGY SAVINGThe EPC reduces the electric energy consumption by approx. 80‐100 kWh/t compared to the conventional EAF. INDEPENDENT SCRAP CHARGING g g p p p y pCharging of the scrap basket is done with power‐on and independently from the furnace operation. This improves the operation and reduce the Power off time HIGHER PRODUCTIVITYDue to shorter power‐on and power‐off times. The productivity of the furnace can be increased bymin. 20 % compared to the conventional EAF.HIGHER RETURN ON INVESTMENTTheTh EPC S t System f t features llower conversion cost d t th preheating effect. F th i t due to the h ti ff t Furthermore hi h higherproductivity because of less power‐on and power‐off are assured.
  • 8. KR Tec R E S P E C T   T O   N AT U R EMINIMUM DUST EMMISIONDuring charging procedure the system/pre‐heating chamber is always in airtight situation which reflects a minimum of pollution in the meltshop.LOW FTP CAPACITY REQUIREMENTFume Treatment System capacity is reduced thank to the completely closed operation and flat bath condition.LOW DOWNTIMES & MAINTENANCENo critical mechanical parts such as fingers, conveyors, water cooling which cause unforeseen stoppages and maintenance. t d i tADAPTABLE TO CONVENTIONAL METHODOperation can be changed immediately to Conventional method by opening of the off gas ‐ bypass Operation can be changed immediately to Conventional method by opening of the off gas bypassflap.LESS FLICKERLESS FLICKERRelated to the flat bath operation, preheated scrap and the constant energy input, a reduced flicker and less noise generation will be achieved.

  • 11. KR Tec EPC SYSTEMThe scrap basket will be charged into a drawer of the EPC system which is in waiting position.While this position the front wall of the drawer is closing the preheating chamber and themelting process in the EAF and preheating doesn`t have to be interrupted.After filling of the drawer by the scrap basket a slide gate on top of the EPC System will be closed.Than the drawer will be forwarded by hydraulic cylinders to the preheating chamber and thescrap falls smoothly inside the pre‐heating chamber where it will be preheated.If the drawer is in front position, the back wall of it, is closing to the pre‐heating chamber.A special design of the off gas duct together with a water cooled regulation flap allows to controlthe preheating effect in the pre‐heating chamber.
