Slitting of hot rolled steel coils
Hot Rolled Steel Coils Strip Processing
The slitting process of hot rolled steel coils consists of the steps of uncoiling (unwinding), priming and positioning, slitting and slitting, and winding (winding).
In fact, the general hot rolled coiled steel slitting processing of the traditional control scheme is to use a large motor to drive the winding and unwinding of the shaft, the winding and unwinding of the shaft is added with a magnetic powder clutch, by adjusting the current of the magnetic powder clutch to control the resistance it produces, in order to control the tension of the surface of the material.
Hot rolled coil steel has excellent properties such as high strength, good toughness, easy processing and molding, and is an important variety of steel. It is mostly used in the following applications:
(1) Structural steel is one of the most important uses of hot rolled steel in coils, used in construction, machinery, automotive, oil and gas industries.
(2) Deep processing of hot rolled thin coils with a thickness of ≤3.0mm into cold rolled coil substrates, hot rolled pickled plates and hot rolled galvanized plates.
(3) Used in the manufacture of hulls and decks of ocean-going, coastal and inland waterway vessels.
(4) Manufacture of pressure vessels or other similar equipment for petroleum, chemical and other industries.
(5) Used in the construction of bridges and railroads.
(6) Steel for oil and gas pipelines is also a major application of hot rolled steel plate.
The following are examples of hot rolled steel sheet in coils slitting shipments.
From the industry of hot rolled steel sheet in coil consumption, mainly concentrated in cold rolled substrates, ships, automobiles, infrastructure, machinery, pipe making, pressure vessels and so on. In addition to containers, railroad steel and other industries manufacturers are more dispersed, other industries are showing some regional concentration effect. Hot rolled steel coils accounted for about 40% of the world's production, amounting to 236 million tons, of which about 149 million tons of medium-thickness wide steel strip production. Because hot rolled steel coil is one of the popular products for export. The processing method of slitting hot rolled steel coils are preferred by many customers, we have rich experience in exporting this kind of products and look forward to your contact!
