Established in the year 2005, Galwalia Ispat Udyog Private Limited is a major constituent of the SPNG Group. With excellence, the group produces quality steel products that come in varied grades and sizes. The unit is well equipped with modern plant and machinery. It uses innovative technology and infrastructure for increased productivity and superior output.
GUIPL owns a lab which is fully equipped with spectrometer, UTM, camera fitted microscope, hardness tester and a fully wet analysis facility that ensures stringent quality control.
The unit has been successfully producing structural steel under the brand name INDOSTARTM. It is a renowned name in the market and is characterized by features such as strength, excellence, resistance to corrosion and dimensional accuracy. The group has indeed set a benchmark for itself in the industry!
Our steel melting shop comprises of 4 induction furnaces, followed by Continuous Caster Machine (CCM) for conversion of molten steel metal into billets of various sizes.
The raw materials which are used for making steel are steel scrap and sponge iron. Sponge iron is basically deoxidized iron in the form of lumps, pellets and fines. Sponge iron and steel scrap are charged in appropriate ratio into the induction furnaces in batches.
After the complete melting of charge, the hot liquid metal samples are taken to analyze the chemical composition i.e. carbon, sulphur, phosphorus, silicon, manganese, etc. In order to balance the chemistry of the metal as per the required grade, silicon, manganese and ferrosilicon is added. The temperature of liquid metal is raised to 1600 degree centigrade for casting.
For billet casting, the liquid steel is poured into the ladle and the ladle is taken to CCM for casting.
Complete Process route for SMS Section
After the casting of billets in required sizes, they are further processed to form TMT. There are 2 processes for manufacturing of TMT:
A) SIZE CONVERSION PROCESS
The thoroughly tested billets are either reheated or hot charged under a specified temperature. They are then subsequently rolled through a roughing stand and a sequence of rolling stands which progressively reduces the size of billets in the desired TMT size. The gradual reduction is an important factor to ensure finer grain structure of the bar. The rolling continues till the desired size is achieved.
B) QUENCHING and NORMALISING PROCESS
The bar after leaving the last rolling stand is fed to a quenching box at a very high speed. In this section, rapid and controlled water quenching is performed reducing the temperature of the surface drastically from around 950 to 600 degree centigrade. Due to higher speed, only the outer portion gets quenched but the inner core remains hot. The outer case due to rapid quenching gets converted into martensite form. The microstructure is fine grained ferrite and pearlite structure at the core and martensite at case. The bar is cut with automatic flying shear and fed into the cooling bed.
At the cooling bed, the core which is still hot transfers the heat outside to the case thereby tempering it. Due to this self-tempering, the martensite case becomes tempered which has more strength and high corrosion resistance properties. Both quenching and self-tempering lead to typical microstructure of TMT bar i.e. fine grained ferrite-pearlite structure at the core and tempered martensite at case. After this, the normalizing process starts where the bars cool down at atmospheric temperature and gradually attain the microstructure.
