"Roller grinding wheel" technology of Zhuomao company has reached the international advanced level. We compete with international first-class brands on the same stage. We have carried out in-depth and systematic research in the grinding of "high-speed steel roll", "Senjamil roll", "mirror roll" and other fields,. By accumulating rich experience, we form our Zhuomao formula system. We can match suitable grinding wheel products according to different material types of rolls and customer requirements, which can be used for grinding the working rolls, intermediate rolls and backup rolls of hot and cold rolling, ensuring the grinding quality of rolls, improving the grinding efficiency of rolls, reducing the grinding cost and meeting customer requirements.

        We are at the forefront of the industry in the application of new abrasives and new technologies. New abrasives: SG, TG and EQ (equivalent to NQ abrasives); The new bonding agents BU, B24, B37, B40, B60 and B69 have the characteristics of good toughness and high strength. We have mastered the world's leading new firing process of low-temperature ceramic grinding wheels, which provides strong support and guarantee for upgrading the quality of domestic cold-rolled sheet and non-ferrous metal sheet.

        At present, the commonly used sizes of our roller grinding wheels are as follows:

        600*60*203.2 ，   710*75*304.8 ；

        750*75*304.8 ，   800*80*304.8 ；

        900*100*304.8 ， 915*100*304.8；

        1066*100*304.8，1066*100*508 ；

        1100*150*304.8，1100*200*508 ；

        Commonly used abrasives for grinding roller wheels are 23A, 23AC, 36A, 39C, N3A, SG and EQ.

        We carry out technical exchanges and friendly cooperation with world-famous chemical companies and abrasive companies such as Baekleiter in Germany, Sumitomo in Japan, 3M in USA, etc., and constantly learn the advanced technology of cutting-edge science and technology to keep pace with the times.

From 2016, the grinding wheels of Huachen grinder factory are no longer foreign brands, but all are our Zhuomao grinding wheels.

        ● Zhuomao grinding wheel has been used in the stainless steel hot rolling and cold rolling production line of Baosteel Group since 2016.

        ● Since 2017, the silicon steel production line of WISCO Group has used our Zhuomao grinding wheel to ensure production.

        ● In April 2017, we conducted a test on the same stage with the international first-class grinding wheel brands "Saint-Gobain" and "winterthur" in Laigang Group. Our grinding quality, grinding efficiency and grinding quantity on the roller surface are not inferior to those of the international first-class grinding wheel brands. Since then, 70% of the grinding wheel orders of Laigang Group have been given to us.

        ● In July 2018, we participated in the grinding competition organized by "Baosteel Shangke Company" for grinding wheels of more than 10 Chinese and foreign enterprises, from which we stood out and became the main supplier of grinding wheels of Shangke Company.
