A solution for instantaneous mass flow control for rolling mills in harsh conditions

ISEND has released a new device that can be used to measure the mass flow in real time and by calculations, the equivalent section or diameter. MASSdiscover uses a technology that allows measurements with the highest precision to take decisions about the process control. It has been used and tested in several rolling mills with harsh conditions. Rolling mills for long metal products production starts with a billet that is passed through several rolls to get the desired final size and cross-section product. The metal processing industry’s high standards in terms of dimensional accuracy and product quality, added to the lack of control over production parameters often leads mills to deliver extra tons of steel, as it is difficult to delimiter quantity with high precision. Thus, rolling mills manufacturers suffer money losses. MASSdiscover goes beyond limits for fine tuning size adjustments on long product rolling mill technology for metals. Mass flow measurement is essential to control production parameters and avoid accidents. To date, expensive systems have been used for production optimisation, usually based on laser measurement, vision or other image analysis systems even electromagnetic technology. All these gauges have limitations, as they are not designed to control different points in the rolling mill, but only one point in the production process. ISEND has found a highly reliable solution based on eddy currents, completely

MASSdiscover is used for fine tuning size adjustments on long product rolling mill technology for metals

The control of these aspects entails enormous advantages for the rolling mill, which in summary will be reflected with reduced line wear and accidents, a high ROI with saving on process time, product, control, maintenance cost, a higher reliability with well-known technology with less maintenance, real-time analysis (during production), improved production with environmental impact and high accuracy and performance. MASSdiscover does not need to be in contact with the product to perform the analysis and its output is not compromised by dirt, powder, steam, water or other kind of pollution in the environment. The mechanical design is one of the main strong points of the MASSdiscover system giving it a high robustness, has no moving parts and requires a little and easy maintenance.

modular and conceived to fit the needs of each production line at a very competitive price. MASSdiscover is based on the already well-known eddy current technology for long product rolling giving an electromagnetic signal depending on the fill factor produced in the probe. MASSdiscover helps companies to adjust tolerances product consistency. Allowing customers to achieve a mini tolerance for longer product for reinforced steel, achieve a mini variation on tolerances to ensure high performance post-treatment for fine drawing, cold heading, final product tensile consistency. When the size and speed of the material does not match the parameters of the rollers, accidents can occur. An example are the cobbles. The system not only helps to adjust the tolerances, but also helps to ensure a good configuration of the production processes.

control, and optional automatic control. All models of the Centerwave 6000 device series are characterised by their innovative measuring principle based on millimetre wave technology. “The “one-button operation” rules out operating errors and processes are optimally controlled.

Christian Schalich, head of sales, hose and tube, said: “The new model can be easily integrated into the production line thanks to its slim design and is particularly suitable for extrusion lines in which pipe diameters of up to 1,000 and 1,200mm are produced.” In-line, the system supports immediate centring, seamless, reliable quality

The Centerwave 6000 from Sikora is designed for the online measurement of wall thickness, inner profile and diameter as well as ovality over the entire circumference of plastic pipes. The new model, the Centerwave 6000 /1200, specifically covers diameter ranges from 250 to 1,200mm and meets
