Transcript of Brief Introduction of HuaFeng


    Ningguo HuaFeng wear resistant material Co.,LTD, locating in Ningguo industrial

    development area, Anhui province. Specializes in researching developing and producting

    wear-resisting cast balls and barscast steel parts.

    Due to the cooperation with Anhui University of Technology Anhui wear-resisting material

    quality supervision and inspection center Hefei kaier nano technology application Co.,

    LTD,and other universities and companies, HuaFeng developed highly sophisticated

    wear-resistant material, by using nano-technology instead of traditional industries. In addition,

    HuaFeng employs Yongmao Yao, a well-known expert, as our chief engineer , who is

    responsible for planningmanufacturingexpansion and brand impacting.

    HuaFeng possesses the ability of producting 50 thousand tons of wear-resisting cast

    balls and bars and 3 thousand tons of high-performance cast steel parts and hammer head.

    Equipped with top-level inspection equipment in Provincial Laboratory full -automatic ball

    casting production lineunique fully-automatic isothermal quenching oil continuous cooling plus

    heat air isothermal heat treatment production linemedium frequency melting furnace, etc,

    HuaFeng guarantees the quality of production.

    Carbidic Austempered Ductile Iron grinding ball, developed by HuaFeng, has been

    identified as new product by Anhui economic and information commission. Also, it has been

    rated as "high-tech product" by Anhui science and technology department and "oil quenching

    plus heat isothermal transformation processing" as new heat treatment technology and

    equipment has passed the certification of Anhui science and technology department . On

    account of its energy saving, consumption reduction, environmental protection and production

    increase, the product has been approved by many domestic large-scale minings.

    HuaFeng has passed the ISO9001 quality management system certification, ISO14001

    environmental management system certification, OHSAS18001 occupational health and safety

    management system certification.


    Ning Huafeng ,one kind of HuaFengs production, is identified as " Anhui famous brand" by

    " Anhui famous brand strategy and promoting committee" and Anhui technical

    supervision bureau.

    Automatic Media Casting Line With high technology content and high automation capability, the automatic producing line worked out by ourselves has effective control by computers on the whole process (from molds moving to twisting and to opening, closing, sand-shooting and temperature adjusting), which greatly reduces the arbitrary operation existing in traditional labor and lessens the extent of workers labor. The most important aspect lies in the improvement on products quality, enhance appearance quality of grinding media, reduction of production costs and increase of enterprises output.


    Media separation equipments The product-partition machine and product-selection machine are equipped with mechanical grinding balls, With the use of such two machines, not only powder pollution and sand-wheel consumption have been out of trace, and also safety accidents have been cut off. At the same time, vibration-handling will be applied in the process of products partition, which promotes the improved quality. Reduce the breakage rate of grinding media.

    Internationally advanced heat treatment process We have developed scientific quenching equipment, which applies oil and air quenching technology and can control the temperature at any time in the course of quenching with far-infrared gear pyrometer. For different specifications of products, the perfect match of different heat treatment, temperature and time are selected to quench to obtain the inner structure of the castings we definitely need.

    Strict QC System

    The quality is assured in the whole supply chain by a strict QC Network supported by: (1) Reliable Suppliers, Logistics Providers, Sales Agents and Distributors, who are evaluated, selected, qualified,

    graded and well managed in accordance with relevant Evaluation and Approval Standards, (2) A Skilled QC Team including qualified Inspectors and experienced TS Engineers, who are trained and qualified

    in theory and ability, (3) Strict QC Criteria and Regulations featured by defects back-tracing, which are well known by and applicable to

    whole staff, especially QC personnel and workers, (4) Periodic Training and Operation Skills Evaluation on workers, whose daily work are in strict compliance with

    Operation Instructions, (5) Different Production Process for different material and property requirements, (6) Automatic Production Facilities, which are fully computer-controlled, flexible enough to meet different needs

    and requirements, and checked, maintained and renewed periodically, (7) An Active Production Supervision System, which provides daily interactive production supervision, (8) Various Test and Inspection Equipments, which are daily used to make continuous tests, inspections and

    analysis on different materials received, products in every process and defects occasionally occurred in production and application (see below the QC Equipments List), preventing defects occurrence in each stage,

    (9) An Experienced Commercial Team, good at international commerce and technology, know different custom and culture, follow up the application status,


    We are conscious that high quality comes from strict control and scientific management, such a QC Network enables the whole supply chain running under control so as to guarantee the quality to meet users needs and requirements in a long term.
