    Equipment for Metallurgy and Steelmaking

    Steelworks operate electric arc furnaces at temperatures above 1200°C, where sensors must withstand heat and chemical attack, and the hydraulic tilting systems require fire-resistant oils. We quote abrasion-resistant slurry pumps, sensors for extreme temperatures, hydraulic systems for furnaces, industrial dust filters and high-temperature lubricants. Send the exact process temperature so we can recommend the right material.

    Frequently asked questions

    Which temperature sensor withstands conditions next to an electric arc furnace above 1200°C?

    For extreme temperatures (sometimes up to 1600°C at measuring points close to the melt), we use type S or B thermocouples (platinum-rhodium), protected in ceramic or refractory sheaths, resistant to thermal shock and to chemical attack by slag. Conventional resistance thermometers (Pt100) do not withstand such temperatures and are used only in cooler zones of the process (cooling, hydraulic circuits). The sensor position and response speed matter as much as heat resistance - a sensor that is too slow does not capture the rapid temperature variations that affect steel quality control.

    Which material withstands transporting slag and oxides at high temperatures?

    For slurry pumps carrying slag or oxides at high temperatures, the impeller and casing must be made of alloys resistant to both abrasion and temperature - high-chromium cast irons lose their hardness above certain thermal thresholds, so hot applications often favour linings or special heat-resistant materials, depending on the real fluid temperature. It is essential to tell us the exact process temperature, because the difference between 80°C and 200°C completely changes the recommendation for material and seal type.

    What requirements do hydraulic systems have for tilting furnaces or operating rolling mills?

    Hydraulic systems in the furnace area often work close to sources of intense radiant heat, which calls for hydraulic oils with a high flash point (fire-resistant fluids) instead of standard mineral oils, for fire safety. Cylinders and seals must withstand the high ambient temperature in the hall, not just the working pressure. For rolling mills, the positioning accuracy of the cylinders directly affects the dimensional tolerance of the rolled product, so proportional valves and position sensors must have high resolution and repeatability.

    Which dust filters are recommended for metallurgical processing halls?

    It depends on the type of particles generated: for fine dust from cutting or grinding, cartridge filters offer a large filtration area in a compact space; for large volumes of gas with coarser particles (furnace dedusting), bag filters better withstand the high temperature of the exhaust gas. The filter media material (polyester, glass fibre, PTFE membrane) is chosen according to the gas temperature and the properties of the particles (abrasiveness, hygroscopicity). A thermally undersized filter can deteriorate quickly, even if it has good filtration efficiency on paper.

    Which lubricants withstand the high temperatures in the rolling mill area?

    Bearings exposed to radiant heat or to high process temperatures need special synthetic greases, which keep their consistency and do not oxidise quickly above 150-200°C, unlike standard mineral greases, which degrade and lose their lubricating capacity. The relubrication interval must be shortened compared with normal-temperature applications, because temperature accelerates lubricant degradation. We supply Klüber products for these applications, with technical datasheets that state the exact temperature limits and recommended intervals.
