Product Description

Qingdao Hexin Machinery Co., Ltd. are professional Centrifugal Casting Sink Roll for Continue Galvanizing Line, Centrifugal Casting Sink Rolls, Centrifugal Casting Rolls, Stabilizer rolls, Furnace rolls for plate heating furnace,  Rolls for CAL, Water cooled rolls, Coated rolls manufacturer from China.

Qingdao Hexin Machinery Co., Ltd. produces furnace bottom rolls,which it adopt the centrifugal casting, precisely casting technology on journal bell mouth, shaft head with forging process. It can be transported with using professional wood packaging to the packing, its excellent quality has won high praise at home and abroad.

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

The slab of the thin slab caster is cut to length and directly enters the roller hearth furnace for soaking and is transported by the hearth roller to the hot rolling mill for rolling.
Special working conditions require the product to be resistant to high temperature, pressure, and abrasion, but also to withstand the impact of the slab head and the friction 
and torsion of the slab movement.

HEXIN Machinery now has full capability sand casting, centrifugal casting, precision casting, machining, riveting, heat treatment, assembly and other main workshops, 
After years of development in the production of heating furnace accessories (heat-resistant steel castings),
 it has provided complete sets of heating furnaces and waste heat recovery systems, as well as centrifugal casting alloy furnace tubes, radiant tubes, steam reformer tubes, steam reformer cold  headers,
steam reformer inlet pigtails in Incoloy800H,Wye fittings, reducers, plug headers,and sharp bends for many refining and chemical projects of PetroChina, Sinopec, CNOOC and Sinochem. 
Rich performance and experience, quality and technical ability.
Especially the large-scale heat-resistant alloy steel castings with large size, high grade and complex structure have extremely obvious advantages in technology and experience.
Centrifugal cast tubes, cast tube sheets, convection intermediate tube supports, hooks, tube sheets brackets and hangers, various furnace doors/peep doors or observation doors, 
air preheaters, flue baffles, butterfly valves, quick-opening dampers, compensators, flue duct systems, etc.
Series products such as heat-resistant steel castings and cast iron plate air preheaters have a leading domestic market share and have a fairly high reputation and reputation in the industry.
Our company uses silica sol precision casting process to produce hooks, tube sheets brackets and tube sheets hangers.
The heat-resistant alloy steel castings produced by HEXIN Machinery adopts resin sand casting technology and silica sol precision casting technology.
