Our Process
That makes all the difference
At Sunrise Multi Steel Pvt Ltd, where we craft our Steel Bars with great care, passion and precision, is located at Rajkot,having a manufacturing capacity of 1.4 Lakh Metric Tonnes Billet production per annum. Sunrise Steel Bars are manufactured using this unique iron & steel making and hot rolling, which makes them stronger, safer and more ductile than any other Steel in the market segment.
SPONGE IRON
Raw Material Selection
An extensive Chemical Analysis of the raw material. Sponge Iron is done by first melting it in 5 KG furnaceand testing in spectrometer imported from Japan, to understand the chemical properties for creating the perfect chemical composition. composition during the process of melting.
STEEL MELTING SHOP
Steel Melting
The Charge Mix is charged in furnace using feeders and melted under close observation of high-calibre metallurgists and engineers to form a homogenous melt with low levels of Phosphorus and Sulphur. Regular Samples are taken to assure the chemical.
LADLE TREATMENT
Ladle Treatment
Once the batch is ready, it is poured into the Ladle where it is purged using inert gases to oxide the unwanted elements.
BILLET CASTER
Billet Casting
The molten metal is solidified into a 'semi-finished' billet using imported mould tubes with ultra-level precision of less than 0.01% variation in section sizes. Appropriate temperature is maintained during solidification using automatically controlled water valves. remains hot.
ROLLING MILL
Hot Rolling
The steel billets are received at Roughing Stand at an approximate temperature of 1000 °C and then hot rolled to reshape the billets into the final size and shape of reinforced bar.
PHYSICAL & CHEMICAL TESTING LAB
Quality Analysis
When the hot reinforced bar leaves the final rolling mill stand, it is instantaneously cooled by water in a quenching box, the most advance QST technology from Germany to prevent the occurrence of undesired processes such as phase transformations. Quenching converts the outer surface of the reinforced bar to Martensite, while the core still.
STORAGE & DISPATCH
Atmospheric Cooling
Finally, the Natural cooling after quenching automatically tempers the austenitic core to ferrite and pearlite on the cooling bed to create a uniform microstructure.
