SIHUB can supply all kinds of labyrinth rings for different types of rolling mills with different materials, with the special requirement of coating or tempering or nitriding.
Can be mounted on a rotating shaft as a main shaft of a machine tool to block external oil, water, dust, debris and other contaminants and prevent water vapor intrusion. Is widely used for the rolls of hot rolling, cold rolling, section mill and bar mill, rebar mill and wire rod mill.
For this product we work with standard measurements, since there are countless measurements and these vary according to the manufacturer. And based on this there are these series:
-SWP series: It is an old-style product.
-SWC series: It is an improved style of the SWP series.
JXC series: light series. The basic structure
Refers to the device installed before and after the rolling pass to help the rolled part enter and exit the pass precisely and stably according to the predetermined direction and state during the section rolling process. of steel. Advantages: You can remove iron oxide scale, You can smooth the surface of the rolled p.
We have worked together with the advancement of technology and the application of large diameter tungsten to offer composite cylinders of more than Φ320mm in diameter that can be used in hot rolled wire rod, rebar, round steel, etc.
The total alloy content of Semi HSS coils is between 8% and 15%, the alloy content of HSS coils is more than 15%, the alloy content is about half of the HSS coil. Semi HSS rolls are mainly applied to roughing stands of hot rolling mills, and work rolls and intermediate rolls of cold rolling mills.
HSS Rolls, High Speed Steel Rolls are made by vertical centrifugal casting process, core material is nodular for excellent toughness, cover material is HSS with high hardness and excellent high temperature wear resistance. The shell is made with high alloy content and special heat treatment process.
Forged steel rolls for hot rolling mills are made from special heat forged steel parts and treated to make rolls with satisfactory roll hardness, depth of hardening. Rolls for hot rolling mills have good wear capacity and high strength.
Forged steel rolls for cold rolling mills are widely applied to work rolls, intermediate rolls and backing rolls. Lonsun cylinders have a homogeneous hardness in the working layer with superior, high wear capacity and excellent accident resistance; the depth of the hardness layer can be greater than 30 mm.
Have good thermal conduction properties, excellent wear resistance, high impact resistance, and good toughness. Tungsten carbide rings have good mechanical properties, bending strength can reach 2200MPa, impact strength can reach (4-6) x 106J/m2. High hardness and wear resistance properties come from WC.
