High slag skimming rate and low hot metal loss: Efficiently remove desulfurization slag before and after KR desulfurization. Thorough slag removal reduces iron entrainment in slag, cuts hot metal loss, lowers resulfurization and rephosphorization in BOF, guarantees purity of hot metal charged into converter, and stabilizes the production of ultra-low sulfur steel.
Compatible with KR stirring desulfurization process: Designed for slag skimming during ladle tilting. It can perform pre-slag skimming before desulfurization and final slag skimming after desulfurization. It removes foamy CaO-based slag generated in desulfurization reactions and prevents residual slag from impairing the efficiency of KR stirring desulfurization.
Stable subsequent BOF operation: Less slag carried over to BOF reduces consumption of converter fluxes and alloys, shortens converter blowing cycle, and improves steel quality and product yield.
High-power hydraulic telescopic skimming arm: Hydraulically driven with fast response and stable torque for telescoping, lifting and tilting movements. Precise position control of the skimming plate adapts to different ladle capacities and variable slag thickness.
High-temperature and wear-resistant construction: The skimming rake and boom adopt high-strength heat-resistant structure with wear hardening treatment. It withstands thermal radiation over 1400℃ and molten slag erosion, enabling long-term operation under harsh high-temperature and dusty conditions with low maintenance frequency and low operating cost.
Remote / automatic control: Remote operation keeps operators away from high-temperature ladle mouth and greatly improves safety. Optional machine vision function can automatically identify slag surface, plan skimming path and standardize skimming endpoint judgment to eliminate discrepancies caused by manual experience.
Compact layout to fit workshop arrangement: Controlled footprint fits existing workshop space in KR pretreatment bay. It can coordinate the production rhythm with KR stirrer and realize parallel slag skimming operation to increase throughput of the whole hot metal pretreatment station.
Complete protection interlocks: Equipped with overload, limit and collision protection to avoid mechanical impact and ladle scratching, protect ladle and machine itself, and prevent hot metal leakage risk.
Shorter skimming cycle: Compared with simple manual skimming, it shortens skimming time, stabilizes production rhythm of hot metal pretreatment, reduces hot metal temperature drop and saves energy for subsequent reheating.
Improved working environment: Closed dust collection works together with slag skimming to reduce escape of high-temperature flue gas and lower on-site thermal radiation and dust pollution.
