Technology and Innovation
In order to maintain our technological leadership and meet the technical requirements of the different types of furnaces( AC/DC, Ladle furnaces), we constantly invest in our production technologies. We have successfully produced large size UHP graphite electrodes with diameters from Dia.600 mm to Dia.700 MM, which filled gap in this field in domestic markets. With the characters of cost savings and good stable performances, our large size UHP graphite electrodes have replaced imported graphite electrodes in domestic market and accepted by overseas famous iron & steel plants gradually.
Quality Assurance System
All production process is led by Quality Management System in accordance with ISO9001:2000 standards. We pay more attention to the inspection & supervision for each process.
Production Process Control The physical and chemical index of raw material , accessories and process product is inspected by quality inspection department.Inspection of product appearance and dimension is made up of self-checking, next process cross-checking and quality inspection department supervising and checking.The production process index proceeds strictly as per production regulation and is controlled by PLC, meantime, PLC will feedback the process index situation to technical and quality inspection department for supervising, to guarantee the product quality.Quality System Control Management delegates and quality inspection department organize internal examine every year to supervise and check system running status.Second party inspection is carried out by end userThird party inspection is carried out by certificaiton authorityPacking and logistic is farmed out to other company, and strictly execute as per Contract items.We have specific after-sales service teams to check our product performances, and feedback the problems to company for improving.Global Sales & Service Network We have set up 30 branch companies and offices in 25 countries, grated nearly 100 authorized agents around the world , established service network composed of more than 100 websites, formed global marketing and service system.
