Our High Performing Foot Rolls for Casters!

Posted 7/6/2018

Let's take a minute to marvel at the performance of CST Pvt Ltd's Foot Rolls.

Need more evidence? We have some real stats of our foot rolls used by Tata Steel, Jamshedpur, one of our cherished clients.  

Caster rolls, foot and upper zero segment locations are required to work in high temperature environments and need to resist a high wear due to erosion caused by the use of casting powders high in fluoride, as shown in the figure below. 


The Solution: A high alloy material Weldclad 800 that has eliminated the wear erosion problem.


The Real Stats:

*actual figures from trials at Tata Steel, Jamshedpur

-Cr hardfaced Rolls- 200 heats (maximum) (Tonnes per heat – 138) 

-HP Roll of CST crossed 2500 heats and still running. 
-Expected to cross 3500 heats. 
-Increase in life: Over Eight times and running.

Hardsurfacing Rolls ?!

Posted 6/29/2018

CST Pvt Ltd stands for Corewire Surface Technology Pvt Ltd. The Corewire is a shout out to our origins and partner Corewire Ltd, UK, a world leader in their field.


So why is our online platform named ‘hardsurfacedrolls’ and not the more conventional choice for most companys-'the company name'. The domain name was not by accident but a well thought of decision.

 When you think of hardsurfacing your rolls, we want you to think of us.


So, what is hardsurfacing or hardfacing?


When rolls start to wear, they lose their dimension and functionality. Hardsurfacing, also referred to as hardfacing, is the application of wear-resistant weld materials (such as wires) to a roll’s surface. A special type of electrode or wire is used for the application. Simply put, it is welding a reinforced layer onto the roll.


It is frequently believed that hardened rolls have a better service life than the original ones. Hardfacing a new roll increases its wear resistance and it helps restore the worn-down surface of an old roll.


At CST Pvt Ltd, we use Submerged Arc Welding (SAW) processes and high performance WELDCLAD surfaces to hardsurface rolls, in addition to our other services and product offerings.

The 5R’s at CST Pvt Ltd

‘Reduce, Reuse and Recycle’ are three R’s, CST Pvt Ltd strongly believes in and implements. The Services we provide include 5 more Big R’s!

Recondition, Repair, Reclaim, Refurbish, and Rebuild 

At CST Pvt Ltd, some of our Services include:

  • Reconditioning and Refurbishing of a wide range of hardsurfaced rolls and wear resistant forged rolls.
  • Repairing rolls for Casters and Hot Strip Mills, and worn parts like chocks, wear liners, forging dies, crusher rolls etc.
  • Rebuilding used forged rolls with a capacity of up to 25 tonnes!
  • Reclamation of worn rolls for running casters.

All our facilities are in-house. And we have reconditioned over 2000 rollers for steel and cement plants in India and all over the World.


So why Recondition and Repair your Rolls?

The reconditioning process reduces tooling costs, increases efficiency, improves shop safety, and increases the productivity of the rollers. It also increases the lifespan of the rolls.

Besides the cost benefit, it helps preserve resources and operate more sustainably, an aspect that has become increasingly important these days.


CST Pvt Ltd offers customized solutions for the wear and tear of your Rolls. Our services ensure that the rolls have a longer life and higher performance after reconditioning at our facility.

Optimizing Your Maintenance Costs

Posted 6/15/2018

At CST Pvt Ltd, you don’t just get a Top-Quality Product, our products and services help optimize your maintenance costs too.

Don’t believe us?!

Take our Pinch Roll Performance, for example. At CST Pvt Ltd, we hardsurface Top and Bottom Pinch Rolls-New or Reconditioned-with the proven Grade Weldclad 4 technology.

This has demonstrated excellent resistance to wear, cracking and pick-up. Furthermore, these rolls are being used by some of our esteemed clients at JSW-Ispat, Tata Steel, Bushan Power and Steel and SAIL plants for over 10 years now. The observed wear on our Pinch Rolls is significantly less than a traditional Cast Roll. 


Our HP Foot Rolls are another example, the HP Rolls of CST have crossed 2500 heats, are still running and expected to cross 3500. When compared to Cr Hardsurfaced Rolls with a 200-heat maximum, our Foot Rolls will help optimize your costs!


We work with all our customer to find that perfect customized solution. Contact us with your enquiries or to request a product specific brochure.

Counting Down to the weekend with a Fifa World Cup Countdown!

Posted 6/8/2018

With only 6 Days to go for the FIFA WorldCup 2018, the incredible stadiums built for this mega event are all spruced up and ready! The stadium constructions made the most use of Russian Steel, with the country even opening new steel plants.


One of the stadiums used 8,000 tonnes of steel to build its translucent roof. In addition, many of the stadiums have used flexible steel frames to allow the venues to be transformed and used for other purposes after the World Cup. This ensures ongoing sustainability of the stadiums. The VTB Arena that can be configured into a 45,000-capacity stadium from a 27,000-capacity stadium, is only one such example.


Cutting-edge engineering concepts have been used to build these transformable structures, keeping the modern shift towards sustainability and recycling in mind. Good things do happen with Steel!

Hardsurfacing Rolls and Roll Assemblies. Steel, Tariffs, steel tariffs, Trump

After the Trump Administration imposed its new tariffs on Canada, the EU and Mexico, there has been much talk about Steel Industries around the World. Many world leaders have voiced their dissatisfaction on how these new aluminium and steel tariffs would affect their exports.


In India, industry leaders and research agencies show no unanimity on how the decision will affect the industry. Many say that as Asia produces more than two-thirds of the world’s steel, it will be ‘minimally affected’ when compared to the rest of America’s trading partners. India’s steel exports to the US remain very low as well. However, some reports have warned that India needs to brace itself for more imports from China into India.


There is good news for the Indian Steel Industry, the Ministry of Steel reported that Steel production in India is forecast to double by 2031, with the growth rate to go over 10%. The country’s share of global steel production is said to increase by 2021, to 7.7 per cent from 5.4 per cent.

At CST Pvt Ltd we are people and environment friendly. We recondition steel rolls, adding to the recycling of steel.

Steel is the world's most recycled material. The recycling rate of steel is well over 80%, with over 600 million tons of steel being recycled yearly (1). The metallurgic properties of steel allow it to be fully recycled. And unlike many other materials, the incentive and infrastructure for recycling steel exists. 

CST is proud to be part of the industry that reconditions and refurbishes forged and hardsurfaced rolls for the Steel, Cement and Forging Industries. 

At CST, we aim to be friendly to people and the environment. We strongly believe in reuse, recycle and reduce. Some of our projects to ensure environment sustainability are installation of solar panels and reusing our waste. We have even made bricks out of our slag!
