Drilled rolls

The main products of the company include: 1. Paper making rolls and drying cylinders in the roll industry, embryo rolling machine, crusher and oil press in the grain and oil industry, refiner, rubber breaker, openers and automated production line of regenerated rubber in the rubber industry, as well as special rolls for various industries. Among them, the new XKJ-480 refiner independently researched and developed by Baofeng is awarded as Dalian Famous Brand Product, which has high efficiency and energy-saving, excellent quality and long service life, and the centrifugal composite casting technology used to process and produce the peripheral drilling and high efficiency internal cooling rolls, which is a high and new tech product of Baofeng with core competitiveness.2. 2.5 meters-8.5 meters of CNC Vertical Turning Lathe in the industry. CNC vertical lathe. Among them, in addition to the normal parameters of the large vertical lathe, we have put into production more affordable light vertical lathe, total customer choice.


Centrifugal composite casting roll technical advantages
1, solidified under the action of centrifugal force, the roll organization is dense, white mouth layer uniformity, no air holes, sand holes, slag and other shortages;
2, centrifugal casting rolls can be set bushings, greatly saving the consumption of raw materials and the weight of the roll itself;
3, centrifugal composite casting rollers due to the absence of pockmarked layer, and uniform white layer, drilling is extremely convenient and fast;
4, centrifugal composite casting roll work surface hardness can be produced according to user requirements, generally up to HS76 ± 2 °, the roll’s wear resistance is good, good internal toughness, quality and stability;
5, the roll working layer of uniform organization, hardness change is small, white mouth layer hardness difference does not exceed HS5 °, to ensure the stability of roll quality;
6, long service life (than vertical static casting rolls can be extended 3-5 times), for the user to save a lot of money;
7, roll size can be produced according to user requirements, the maximum diameter of 1000mm, length up to 6000mm.
