The engineering team and Duer Carolina Coil has been manufacturing springs for well over 100 years and has refined the coil spring manufacturing process for the industry – for all types of coil springs. Coil slitting, or roll slitting, is the process in which a large master coil is uncoiled and sent through a set of two circular wheels, or shears. Macsteel Coil Processing processes the full range of hot rolled, cold rolled, high chrome, galvanized, pre-coated, flat products and slit material including decoiling/recoiling capabilities of material to 2 000mm widths and up to 30 tonne coil mass capacity. The hot rolled process is a process in which rectangular steel ballet transforms into a steel coil. While being rolled on the table, the strips are sprayed with water to cool them to the proper temperature for coiling.  A4.4 - Hot rolled coil - Supraform® - S315-S700 MC Get contact details & address of companies manufacturing and supplying Hot Rolled Coils, HR Coil across India. Its a discussion of the differences between hot #rolling and cold rolling processes. The process in which hot rolled is produced begins with heating slabs of steel to approximately 2,300 degrees Fahrenheit. If the material does not catch fire the right way, there will be some defects … The billet gets heated and sent for pre-processing, where it is flattened into a large roll. (2010). Slabs produced from a continuous casting system are rolled, cooled and coiled into the sizes required by the customers. Definition & differences. Order Information 21 1 . Manufacturing Process. Hot-rolled coil is used to manufacture steel structures, pipes and closed sections, as well as to enclose structures and facade elements. 6261, Donghaean-ro, Nam-gu, Pohang-si, Gyeongsangbuk-do, Republic of Korea. Hot rolled steel products are divided into two groups: hot rolled coils produced through hot rolling and hot rolled steel plates, which are made by cutting material from hot rolled coils. The DC ingot is usually cooled after casting to room temperature and then re-heated to around 500 °C prior to successive passes through a hot rolling mill where it is reduced in thickness to about 4 - 6 mm (Figures 1301.02.01 and 1301.02.02). Hot rolling and cooling of the surface needs to be thoroughly observed and fully inspected. The amount of heat directly affects the properties of the steel. A wide variety of steel coil manufacturing process options are available to you, such as local service location, applicable industries, and warranty.
