We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.
At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.
The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%
From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:
Waste code: 10 02 10
The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.
Chemical analysis of the material is available on request.
Tungsten carbide roll ringsare rolls made of tungsten carbide and cobalt and other materials using powder metallurgy methods. There are two types of carbide rolls: integral and combined. Superior performance, stable quality, high precision product processing, good wear resistance and high impact resistance
Other specification can be made upon customer' s requirements
Carbide round bars have superior hardness, flexural strength, concentricity and straightness.
1. The round bar is press molded by molding and extrusion.
2. The cemented carbide round bar is sintered by a low-pressure sintering integrated furnace, thus the overall performance is high.
3. The rough tungsten-cobalt carbide round bar, or the outer diameter of the round bar can be refined and polished according to any tolerance. The common tolerances are h6, h7, -0.005, etc., and the round bar end chamfer can also be processed.
4. Carbide round bar is suitable for the processing of general steel, cast iron, stainless steel, heat resistant steel, nickel base and titanium alloy. Recommended for general purpose carbide tool materials such as twist drills, end mills, taps, and gun drills.
5. Round rods with diameters from 0.3 to 40mm are available in lengths up to 400mm. We can also provide products according to your drawings.
Tungsten carbide cold rolls is the main products of UKO, our cold rolls is used in reinforcement wire cold rolling and forming, we had more than 15 years experience to processing cold rolls, and exported to 21 countries for more than 4 years, till now, 0 complain of the quality.
Our rolls include PR,CA,CO,RT,RO,FO type. Also could make it as per customer requirements.
The material of rolls blanks we used are sintered in HIP furnace, 100% virgin material.
Conventional size of UKO tungsten carbide rolls:
1/ general introduction of tungsten carbide wire roller:
With more than 16 years experience of manufacturing tungsten carbide rollers for the metal working industry,
For wire and bar drawing plant, uko has gained business partners from various direction with positive feedback.
Tungsten carbide wire roller including
Descaling roller
Stress reliving roller
Straightening roller
Guide roller
2/reference size and application of tungsten carbide wire rodller:
Descaling rolls are made of tungsten carbide or steel and are used for the mechanical descaling of entry rod in reduction mills.
Stress relieving rolls are made of tungsten carbide to improve the mechanical characteristics of the cold rolled wire.
The roll-straightening process is a cold-forming process that uses rollers to provide uniform bending
Of wire and/or rod material to change its shape and possible other characteristics for use in subsequent processing.
