Mill Rolls of Rebars and Profile
Cast iron rolls and high speed steel rolls be used for rolling rebars and profile. Cast iron rolls be used in the roughing stand, intermediate stand, and finishing stand. High speed steel Rolls be used in the pre-slitting stand and slitting stand in rolling rebars. With good alloy elements and good heat treatment, we keep mill rolls with good working performance.
-
Mill Guides & Restbars & Loopers
Mill guides are to help billet safely pass through rolling mill, It also has the function of clearing oxide scale of billet, and making surface of billet more smooth. As rebars touch guide rollers directly, it should have good wear resistance. Hotion could produce different kinds of guides and guide rollers applied in different kinds of rolling mills.
-
Cemented Carbide Rings & Rolls
Cemented carbide rings are widely used in the intermediate stand, finishing block and sizing mill. Cemented carbide has good hardness and wear resistance. It is the best material of mill rings for high speed rolling. Also, it is used on composite rolls for last stand of rebars. Composite Rolls is the best way to keep high rolling tonnage.
-
Forged Steel Rolls
Forged steel rolls be used in the cold rolling line. In order to get better working peformance, forged steel rolls should have good wear resistance, good roughness retentivity, good anti-accident and good uniform hardness. Hotion could produce the forged steel rolls with the material of 2%Cr, 3%Cr and 5%Cr.
-
Pinch Rolls of Coil Box
Shear Blades are used to cut steel strip and rebars. According to the temperature of steel, we use different material of shear blades in hot rolling and cold rolling. The shear blades have good impact resistance and wear resistance.
-
Table Rollers
Cooling bed rollers are used to transport steel strips, billets and wire coils. The cooling bed rollers suffer high temperature from steel and heavy load of steel. In order to keep stable transportation, rollers should have good wear resistance and bending resistance under high temperature of steel products.
-
Leveller Roll
Roll cassette is used for straightening strip and galvanized sheets. According to the working condition of roll cassettes, striaightener roll should have good hardness, good machining precision, good bending resistance and torsional resistance.
-
Copper Mould Tube
Copper mould tube is the most important spare parts in the crystallizer. It makes liquid steel coolling to form solid steel. As the important thermal conductive parts, the quality of copper mould tube will effect the surface of billet and the speed of continuous casting machine.
-
Electromagnetic Stirrers
The electromagnetic stirrers be used in the continuous casting to improve the products' quality and increase the steel production. EMS effects the flow of liquid steel in the internal casting billet under the electromagnetic force. Hotion could offer many different kinds of EMS according to application position.
-
Continuous Casting Machinery Rollers
Continuous casting machinery rollers be used for supporting and guiding steel billets. As the rollers suffer the high temperature and heavy load, it requires rollers have good high temperature resiatance and good wear resistance.
-
ERW Tube & Profile Roll-forming Rolls
ERW tube rollers are used in the cold roll forming, mill rolls suffer big extrusion force and friction force. So it requires mill rolls should have uniform hardness (HRC58-62) and deep working depth(≥6mm). Also, it should have good strength, good toughness and good fatigue resistance.
-
Seamless Rolls &Tube Plug & Mandrel
In the production process of tube, piecrcing process is very important. Piecrcing plug and are the key spare parts. Piecrcing plug suffers stress, stress, and surface force. Also the working temperature will be 900℃. We produce piecrcing plug with forging process to achive good density and strength.
-
Hearth Rolls
Hearth rolls are widely used in the continuous annealing furnace. Under the temperature of 950℃, hearth rolls have to suffer heavy load and erosion of gas. According to this working condition, Hotion could offer many kinds of hearth rolls with the material of heat resistance steel.
-
Sink Rolls & Stabilizer Rolls
In the galvanizing line, sink rolls and stabilizer rolls suffer the liquid zinc temperature of 450-480℃. As sink rolls and stabilizer rolls are rotated by galvanized sheet, it requires that sink rolls and stabilizer rolls with good corrosion resistance and good wear resistance.
-
Radiant Tube
Radiant tube be used to heat strip steel in the continuous annealing furnace. Gas is burned in the radiant tube. So it requires radiant tube has good high temperature resistance. Hotion produces tube with centrifugal casting process to achive good casting property. The type of radiant tube has W/U/Single end type.
-
Transmission Shaft
Transmission shaft is connected reduction box and driving end. It helps reduction box to offer driving force for driving end. We focus the transimission shafts which be used in steel plants. It has included tooth-curved gear coupling, unniversal joint shaft, and universal coupling.
-
Copper Tuyere
Copper tuyere is the important spare parts for intake air of blast furnace. As the working condition of blast furnace is very bad, the working life of copper tuyere has important effect for the liquid iron production.
-
Sliding Plates
Copper stave be used in the blast furnace to cooling temperature. With the high heat conduction ability and the thermal shock resistance, it makes cooling uniform and stable. Also copper stave has the characteristic of thin-wall, light quality and easy installation.
-
Graphite Electrodes
Graphite electrodes be used in the EAF steel smelting. It is the important spare parts for high temperature electric conduction. It makes furnace burden melting by the electric arc between top of graphite electrode and furnace burden.
-
Mill Bearing
Mill bearings are used on the roll neck of rolling mill or the other transmission position of rolling mills. It is usually used double row cylindrical roller bearings and four row tapered roller bearings on the roll neck of rolling mill. Except normal mill bearings, we also could offer other series of mill bearings.
-
Refractory Materials
Refractory material is applied in all industries where the metal melting vessels must be protected against high temperatures. We supply a full range of refractory products for all applications within the iron industry.
