Everything You Must Know About Pinch Rollers Used In Steel Rolling Mills

 

When we talk about pinch rollers and their utility and operation in the steel rolling mill, the first question that often comes to mind is what exactly is a pinch roller. Today, let us take the time to learn about them and how they are used. 

What is a Pinch Roller?

A pinch roller in a steel rolling mill is a vital element and machinery that facilitates hot rolling. They function on a horizontal cantilever structure with an air cylinder and a double roll device. This permits it to regulate the synchronous clam that moves up and down. Pinch rollers tend to have a certain opposition to the adhesion of different metals and also have an intrinsic property that allows lubrication. Their job is also to assist in eliminating coil rejection whose surface quality is not up to standard.  

The metallurgical aspects of the rolls help in delivering resistance to the bond and the abrasive wear. It also aids in improving and extending the length and providing equal wear to each pinch roll utilised in the process. Overall, pinch rollers are created to provide optimal performance and can satisfy the needs of hot steel strip coiling usage.

Types Of Pinch Rollers Used In Steel Rolling Mills 

1. Billets Pinch Roller

Billet pinch rollers are placed right before the roughing mill. The job of the billet pinch roller is to hold onto the rolling stock. Doing so ensures that the rolling stock maintains a specific level of tension and stable forward transportation.

2. Segmentation Pinch Roller 

The segmentation pinch roller machine is positioned at the fold-out flying shear machine outlet. It can be adjusted to tilt and move the overall layout and the positioning of the upper cooling bed roller form. The arrangement is an oblique formation that includes pairs of four pinch rollers with alternating control pinch roll devices.

3. Pinch Brake Roller

The pinch brake roller is mostly utilised for the purpose of single-line rolling of the pinch and brake. It is also used before and after cutting flying feet. It is also responsible for holding back rolling stock to ensure that the rolling stock preserves a certain tension and stable transportation.

4. Swing Pinch Roller

The swing pinch roller is used for dual-motor drive form. In this case, both the lower and the upper rollers function with the assistance of AC motors via coupling.  Both motors maintain their speed by utilising the same inverter. The cylinder drives the upper roller, making it move up and down. This function, in turn, controls the clamping and unclamping fiction of the workpiece. 

5. Vertical Pinch Roller

The vertical pinch roller is generally used to roll the pinch in a single line. It is also employed before and after cutting flying feet. It is also responsible for controlling back rolling stock to guarantee that the rolling stock keeps a specific tension and stable transportation.

6. Tail Breakers

Tail breakers are put into position just behind the flying shear and before the cooling bed to lessen the momentum of TMT bars. It performs with AC and DC variable drives, and the pneumatic cylinder disconnects them. 

7. High-Speed Pinch Roller

High-Speed pinch roller is utilised at a different location in the rolling mill before and after the TMT quenching box. It is done to supply continuous tension to the bar. It is also developed with a spherical roller bearing.

The Founding of Steefo by Mr Krishnakumar Agrawal

Mr Krishnakumar Agrawal founded Steefo in 1976 with a small machining company. He coined the name STEEFO from Steel Forming and set out to pursue his aspirations of expanding the steel business and doing something noble for our country. He began by manufacturing and delivering machinery and components for steel plants. Driven by Mr Agrawal’s unwavering commitment, it was evident that the company was on the path to achieving its first milestone.

Steefo Industries’ First Rolling Mill Order

We started supplying large parts and soon began accepting turnkey orders. In 1991, we exported our first order to BSRM Steel Limited in Bangladesh. We eventually gained a lot of praise as market trust in our products grew. We completed three turnkey rolling mill orders for Melbourne Metals in Sri Lanka between 1995 and 1997. 

Mr Sandeep Agrawal’s journey

The company’s growth trajectory jumped with the entry of Mr Sandeep Agrawal, the son of Mr Krishnakumar Agrawal, in 2006. With a desire to build and expand Steefo Industries, he elevated the company to new heights in the market. In the same year, he introduced the concept of “joint ventures” and led a successful collaboration with Taiwan’s Grand Noble Engineering. His goal was to deliver exceptional work and earn trust and respect in the steel business. 

Technological Advancements and Client Base Expansion

By 2011, Steefo Industries achieved a major milestone by completing its first turnkey project for a steel plant order involving SMS and RM. Mr Sandeep Agrawal spearheaded the implementation of technological improvements, ensuring superior product outcomes. Steefo Industries also completed a semi-turnkey order for BKV in 2012.  

Diversification and Vertical Integration

Mr Sandeep Agrawal, with his expertise in the industry, also joined hands with BLS Melt Shop and Rolling Mills in Turkey. He expanded into many sectors, such as the motor division (Rev Power Electric), fabrication division (VisionTech Engineering), and TMT bar division (Vibrant TMT). With the establishment of his own rolling mill units, he contemplated that the product could be thoroughly inspected and tested in their facility before it reached the consumer. He had the courage not to rely on others to test a new product in order to create it. 

Continuing the Legacy

The legacy of Steefo Industries continued with the appointment of Ms Aashna Agrawal, daughter of Mr Sandeep Agrawal, as the marketing & business development head. Mr Krishna Kumar, Sandeep Kumar, and Aashna Agrawal exemplified this – THE DAY YOU STOP MANIFESTING OTHER’S LIFE, YOU START CREATING YOURS. Steefo Industries stands as a testament to this philosophy, constantly growing and evolving.
