Company Information
Shandong Iraeta is a Sino-Spanish joint venture and its shareholders include Gestamp group which is the biggest steel deep processing enterprise of Spain. Shandong Iraeta has been one of the leading forging enterprises of China since it started business in 1975, Until now, it owns more than 20 international and industrial certifications and has assisted the draft and approval of two national industrial standards as well as one Torch Program project.
With over 20 of the global top 500 enterprises purchasing various kinds of forgings from us for different uses, we have customers in the fields of mining, shipbuilding, Petrochemical industry, wind power mechanical manufacturing, ect.
Raw material
Iraeta had strict quality control procedures for raw materials which were only purchased from audited steel mills, so the performances of grinding ball could be assured from source. Moreover, Iraeta set up the academician workstation cooperated with Shenyang Metal Institution of CAS, which enabled us to supply customized raw materials since the grinding media requirements varied by different region mines.
Technical strength
With our special heat treatment, the grinding rod has low wear rate, high hardness (about 45-55 HRC) and good toughness.
After removing the internal stress by quenching and tempering, our grinding rod will not break, bent or thin for two sides. The good resistance will help customers decrease the total costs. With the powerful technological strength, we are capable to meet customersâ?? requirements for any specification, which increases flexibility largely and reduces unnecessary waste.
The annual output of grinding ball is 200 thousand tons with available size dia 25mm-150mm. The high-speed production lines are all controlled by computers, which decreases manual intervention and guarantees product quality and stability. From source to finished product, we strive to manufacture high-quality and high performance grinding steel balls.
