Slab online width adjustment crystallizer

Online Width Crystalizer for Slab

Efficiently managing the width of a slab is key in controlling costs and optimizing throughput in the hot rolling mill. The online Width Crystalizer, a product of world-leading supplier of process measurement and control solutions, ABB, provides an advanced solution to this challenge. The Width Crystalizer, connected to ABB’s Online Slab Analysis System, uses proprietary algorithms to analyze slab images in order to calculate and set the optimum gap width.

The Offline Width Crystalizer provides the same advanced technology to deliver more economical gap adjustment solutions. With this system, the gap width is optimized by using slab images acquired through two offline sensors. The system calculations consider the size of the slab, the amount of material on the edges, the shape of the edges, and the surface condition of the slab. This ensures that the best gap width setting is achieved for every slab, optimizing output with minimum loss of material.

The Width Crystalizer is able to monitor and adjust gap width quickly and accurately, and is able to maintain a nominal gap width of +/- 0.5 mm. When the gap is too wide, the system will adjust it to the optimum level, and if the gap is too small, the system will open it up. In addition, when a slag-free finished product is required, the Crystalizer can be programmed to open the gap slightly wider and fill in the voids with slag to produce a high quality surface.

The Width Crystalizer is easy to install and operate, making it ideal for modernizing hot rolling mills. Its modular structure simplifies maintenance and replacement, while the advanced algorithms allow for fast and accurate gap setting. This system is also compatible with other ABB systems, providing an integrated and efficient production environment.

The Width Crystalizer is designed to operate in the most demanding environments, offering reliable and consistent performance in harsh conditions. Its robust construction and design allow it to operate in high temperatures, while the sophisticated cooling systems ensure optimal performance. This system also provides a high degree of safety and reliability with safety brakes and secure control systems.

The Width Crystalizer from ABB offers a comprehensive solution for optimizing gap width in the hot rolling mill. Its advanced solutions, reliable performance, and modular construction make it an optimal choice for increasing throughput and improving quality in the hot rolling mill. With the Crystalizer, operators can be sure of consistent quality, reduced waste and improved production efficiency.

Continuous Adjustable Width Billet Crystalizers are a practical and versatile method of controlling the geometric shape of billets in a cost-effective manner. By adjusting the width of the billet crystallizer, the surface area and cross-section size of the billet can be adjusted without stopping production. These crystalizers can be used in hot-rolling and forging operations in order to produce long bars, tubes and flat Billets with consistent geometry.

The Adjustable Width Billet Crystalizer is composed of several rollers or roll stands, each powered by a motorized drive train in order to regulate the linear speed and pressure on the incoming billet steel. The rollers are adjustable along their length and move in relation to one another in order to widen or reduce the spacing between them. This provides the desired width of the billet steel as it passes through the crystallizer.

The Adjustable Width Billet Crystalizer is also equipped with an automatic temperature control system in order to ensure consistent results throughout the entire operation. The crystallizer is cooled with a water jet system which evenly distributes the coolant temperature throughout the entire panel width. This maintains the billets’ temperature, which is crucial for the quality of the output product.

In addition, the Adjustable Width Billet Crystalizer also eliminates hot spots in the rolling process, which can distort the final shape of the billet. This ensures a uniform grain structure and smoother surface finish in the finished product. The adjustable width system can also be used to roll billets of varying thickness, ranging from thin-walled tubes and profiles to thick-walled tubulars and plates.

The Adjustable Width Billet Crystalizer is a highly efficient and durable solution which offers significant advantages and production flexibility over traditional methods of billet rolling. It is an ideal choice for high-volume production operations, providing a cost-effective alternative to the conventional methods.
