Continuously manage magnetic fields and high temperatures
At no other place in the steel mill is process reliability as important as at the blast and arc furnaces. For once it is commissioned, a blast furnace is used around the clock over the course of years – hardly possible without continuous water cooling and replenishment.
And just as critical to the process: absolutely reliable immunity to magnetic fields, safe inflow and outflow of gas when producing pig iron in the blast furnace, exact positioning of the electrodes in the arc furnace as well as controlling the conveying equipment. These are reasons enough to focus on every single detail.
Balluff solutions take over control functions at critical positions: our pressure sensors reliably measure water and air pressure. Magnetostrictive linear position sensors or inductive standard sensors monitor flap opening for controlling air intake and exhaust in the blast furnace. And in the electric arc furnace weld-spatter-resistant and magnetic field-immune inductive sensors check the precise position of the electrodes before they are properly gripped, assisted by color sensors.
Sensors for detecting color and contrast support the positioning of electrodes in the arc furnace. The sensor, which is protected in the gripper, checks whether it has been gripped correctly using color markings on the electrode – with absolute reliability and at various temperatures.
Increase process quality through reliable position detection. Our BES inductive sensors stand out especially in the harsh surroundings of the steel industry. Weld field immune and insensitive to magnetic fields, they are extremely reliable in ensuring the correct electrode position at the arc furnace.
Inclination sensors from Balluff with their extremely high accuracy of 0.1° offer the safety steelworkers need. They ensure precise location control of the cover or the casting ladle and continually guide the ladle as the pour is made. Their outstanding resolution provides extremely exact angle measurement even when rotational movement is involved.
Sensors with extremely low drift, such as the BSP pressure sensors from Balluff, ensure efficient water cooling. They are ideal for use in the steel plant, where they ensure a long, stable pressure measurement process on blast and electric arc furnaces.
Optimize your processes in pig iron production. And for valve and flap control on the blast furnace, use BES inductive standard sensors or BTL magnetostrictive linear position sensors. These help you to regulate the intake and exhaust air. All BTL sensors with a bus interface have temperature measurement integrated into the electronics head for displaying a possible overheating of the measuring system.
Extremely reliable and precise under extreme conditions: this is how BUS ultrasonic sensors from Balluff do their job. This makes them perfect for controlling the stack heights on conveyor belts as well as levels in silos. Unaffected by the harsh conditions in a steel plant, they detect objects made of many different materials and ensure you of reliable blast furnace charges even around the dust and dirt from burden material and coke.
