Tungsten bars, rods, profiles and profiles plates, sheets, strip and foil of a deeper level of processing products export tariffs, so the 5% export tax rebate policy will continue. It can be understood, at least for now, for this type of tungsten production and exports, the country is still allowed, and even encouraged.

Slitting machine blade spacer
Blade casing material were S45C, S 50C, 65Mn, etc., which is commonly used material S45C. Using the blade casing is designed to allow circular knife slitting can maintain a certain width between the upper and lower knives and horizontal adjustment of the gap; common blade casing thickness between 0.9mm ~ 100mm [tube body with anti-grinding Molybdenum plate, after forging, machining, heat treatment, leveling finely ground], hardness of 47 ± 2 degrees, the blade sleeve thickness tungsten carbide inserts control 0.003m/mt also less. To reduce weight, we can produce the aluminum spacer, material AL7075, the thickness tolerance is also controlled at 0.003m/mt less.
We can also according to customer requirements in the outer rubber sleeve attached to successfully bring out the knife roll material to prevent scratching; rubber sleeve commonly used green Ding, nitrile amine resin and other natural virgin rubber, made by precision scraping gum sclerosis [IRHD: Blade casing material were S45C, S 50C, 65Mn, etc., which is commonly used material S45C.
