HEXIN MACHINERY , producer of heat resistant castings

  wet rolls for tunnel furnaces HEXIN water cooled rolls have been performing well in tunnel furnaces throughout the world ,which are made by high nickel alloy tires welded to steel shaft, including a castable refractory or without the refractory. The wet rolls perform well in atmospheres over 1300 degrees  C.  The nickel alloy tires are made from heat reistant stainless steel like 2.4879, by lost wax invesment casting method with special heat treatment. We also supply customized alloy tires or ring to customers for installation by themself. We also produce other castigns for CSP plants, like dry rolls for tunnel furnaces, riders for walking beam or pusher type reheating furnaces in nickel and cobalt based alloys, looper rolls, run out table rolls, wrapper rolls. Other components for plate mill and tube mills like tube mill pierce points,plate mill heat treat hardening furnace rolls, rider tiles, hearth skids, buttons, drop-out skids,recuperator boxes, recuperator tubes

  wet rolls for tunnel furnaces :      My company produces the water-cooled roller to use in continuous annealing furnace, continuous galvanizing line and other cooling system, cooling water flow s   from one side of the roll along the r oll neck to   other side   in order to make the roll surface cool, we make the use of heat exchange in surface contact   between strip and roll , so as to achieve the purpose of cooling steel strip.My company optimize the structure of the water-cooled roller , improve the cooling efficiency   and prolong the service life of the water-cooled roller. water cooled hearth rolls After the size cut, the thin slabs are conveyed into furnace directly after that are   conveyed by hearth rolls to the hot roll mills. special operating conditions demands the products with high temperature resistant, to  meet the operating conditions, we make the roll collars, spindle noses and roll   barrels by diffe...
