Sale service

Sales monitoring product usage at any time, the goods to the customer designated place within a week, the sales staff telephone inquiries about the acceptance and other requirements. Assist installation services, this paper introduces the use method and technical requirements.

After-sales service

Training: operation to the steel factory or the customer production sites for the on-site training for operation and maintenance.

Technical support: we received technical support from the user request or after failure report, it will immediately by phone way get in touch with the unit, and guide the user to solve the problem.

Remote network support, realize the company's web site and email online technical support,

Site service: if you need engineer scene understanding and judgment, and solve the problem, our company promises will be received within 8 hours after failure to arrange technical personnel to the scene.

Supervision and management of service: if users are not satisfied with our field service personnel, can feedback to the company, the company will further arrange technical personnel to the scene to solve the problem.

Product Process

Graphite electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch.after calcining,burdening,kneading,forming,baking and pressure impregnation, graphitizationand then precision machined with professional CNC machining. such of the products own characteristics with low resistivity, good electrical conductivity ,low ash, compact structure, good anti oxidation and high mechanical strength, so it is the best conductive material for electric arc furnace and smelting furnace. According to its quality indicators, graphite electrodes can be divided into RP graphite electrodes, HP graphite electrodes and UHP graphite electrodes.

Installation Instructions

cc

1.The electrode holder should be held in the place beyond the security line of the top electrode;otherwise, the electrode would be easily broken.the contact surface between the holder and the electrode should be cleaned up regularly to maintain a good contacting,the cooling jacket of the holder shall be avoided from water leakage. 
2.Identify the reasons it there is gap in the electrode junction,do not use them until the gap is eliminated. 
3.If there is falling off of nipple bolt when connecting electrodes,it is necessary to complete the nipple bolt. 
4.The application of electrode should avoid of tilting operation, particularly , the gr.oup of connected electrodes should not be put horizontally so as to prevent from breaking. 
5.When charging materials to the furnace,the bulk materials should be charged to the place of the furnace bottom,so as to minimize the impact of the large furnace materials on the electrodes. 
6.The large pieces of insulation materials should be avoided of stacking on the bottom of the electrodes when smelting .so as to prevent from affecting the electrode use,or even broken. 
7.Avoid of collapsing the furnace lid when rising or dropping the electrodes,which may result in electrode damage. 
8.It is necessary to prevent the steel slag from splashing to the threads of the electrodes or nipple stored in the smelting site,which may damage the precision of the threads.
