A hot steel descaling system removes the oxide scale that forms on steel during furnace reheating, when temperatures reach up to 1250°C. PressureJet Hot Steel Descaling Systems use high-pressure water jets to remove this scale from billets, blooms, slabs, pipes, TMT bars, ingots, profiles and wire rods without damaging the steel. PressureJet states over 90% descaling efficiency, based on its header design and impact force calculations tailored to material and furnace type.
Hot Steel Descaling System
Get More Than 90 percent descaling Efficiency with Unique PressureJet Descalers
PressureJet Hot Steel Descaling Systems are engineered to deliver exceptional descaling performance, achieving over 90% scale removal efficiency thanks to our unique header design and optimized impact force calculations tailored for different materials and furnace types. Each descaler is precision-engineered to generate high-pressure water jets with razor-sharp impact, producing mechanical force strong enough to efficiently remove oxide layers from billets, blooms, slabs, pipes, TMT bars, ingots, profiles, and wire rods.
During the re-heating of metal in furnaces, surface scale forms due to high temperatures up to 1250°C, oxygen, and process gases. PressureJet descalers remove this scale without damaging the steel, while angled high-pressure jets wash away the loosened oxide, ensuring defect-free surfaces and minimal material loss.
PressureJet Hot Steel Descaling Systems eliminate manual scale handling, ensuring safer operations while delivering superior surface quality for end steel products. By efficiently removing scale, our systems reduce wear on rollers and extend their operational life, resulting in higher productivity and lower maintenance costs.

Frequently Asked Questions
A rolling mill needs a high pressure descaling pump system matched to its steel grade, furnace and product, and PressureJet builds hot steel descaling systems in three pressure bands: 150–200 bar, 200–300 bar and 300–400 bar. Primary descaling systems remove bulk scale immediately after furnace heating, while secondary systems remove remaining scale after rolling. PressureJet supplies solutions for mild, high carbon, alloy, bearing, tool and stainless steel hot rolling mills, and steel plants can consult PressureJet experts for sizing.
PressureJet Hot Steel Descaling Systems are engineered for TMT bars, and the secondary descaling system is the stage the page assigns to TMT bars, edges and profiles after rolling. Primary descaling removes bulk scale after furnace heating. The systems operate across 150–400 bar, and listed accessories such as an infrared hot metal detector can switch the descaling water on and off in sync with the rolling process.
PressureJet's ESB Series skid-mounted custom system for hot steel descaling is rated 150 HP to 180 HP and covers 150 bar to 400 bar. Accessories listed for descaling systems include a VFD control panel, pulsation dampener, 80–100 micron sand filter, DV 80 dump valve built for continuous operation at 350 bar, hot metal detector and IoT telematic monitoring. The page does not publish flow rate or a full duty table, so confirm the exact duty point with PressureJet.
PressureJet states that its Hot Steel Descaling Systems remove scale without damaging the steel, giving defect-free surfaces with minimal material loss. Removing scale efficiently reduces wear on rollers and extends roller life, which the page links to higher productivity and lower maintenance costs. The systems also eliminate manual scale handling for safer operation. Accessories support automation, including infrared hot metal detection and VFD-based speed and pressure control.
PressureJet builds its hot steel descaling systems on high pressure reciprocating triplex plunger pumps, and its descaling range runs from 150 to 400 bar, with the ESB Series rated 150 to 180 HP. PressureJet does not list a quintuplex descaling pump on this page. Pressure pulsation from a reciprocating pump is managed with accessories such as a pulsation dampener, which stabilizes discharge flow and nozzle performance. Confirm the pump type for your mill's duty with PressureJet.
