How much to stock before a maintenance shutdown and when it should arrive are the questions customers ask most often. WeiBeam answers from three angles, consumption estimating, specification mix and lead time, and explains how a spare parts plan can be aligned with the maintenance window to cut waiting time.

When a cold furnace is started, contact between the molybdenum electrode and the molten glass is insufficient, and arcing readily occurs at the end face and near the melt line. This article analyzes the causes of arcing and the forms of damage it inflicts on the electrode surface, and sets out staged current ramping, control of melt coverage, fixed observation positions and an order of response for abnormal conditions, to help the shop floor keep start-up arcing within an acceptable range.

The article analyzes the characteristics of maintenance projects, specification matching for spare parts and delivery management, and highlights details that are easily overlooked when restocking.

Cracking and melt leakage around the electrode hole often stem from molybdenum and the refractory expanding out of step during heat-up. This article compares the expansion behavior of the two material groups, explains how hole diameter, installation clearance and seal design are determined, and shows how the heat-up schedule should slow through critical temperature ranges to limit thermal stress and hole-wall cracking.

Sapphire furnaces buy a complete hot zone rather than a single part. This article compares crucible consumption, heat-shield deformation and their effect on the temperature gradient in the Kyropoulos and heat-exchange routes, sets out crucible dimensions and densification requirements, and proposes a spare-parts rhythm so procurement and maintenance plans can be split by furnace type.

After shutdown, glass clinging to the electrode surface both impedes heat dissipation and alters current distribution. The article explains the conditions under which the deposit forms and where it appears, its effect on electrode temperature and effective conductive area, the scraping tools and working direction to use, the inspection requirements after cleaning, and the practices such as hammering and grinding that should be avoided.

Henan's glass scale is moderate but its molybdenum processing base is deep, and electrode consumption spans glass and high-temperature processing. The article breaks down the category mix, compares furnace types in Luoyang and Ruyang with Anyang and Shangqiu, explains why finished electrodes still have to be sourced outside the province, and provides selection guidance, a reference cost structure, logistics lead times and annual framework stocking advice.

WeiBeam has released a new generation of high-performance molybdenum electrodes covering glass melting furnaces, ceramic fiber, glass fiber, rare-earth electrolysis and crystal growth, with specialty manufacturing processes and a complete electrode solution from selection to delivery.

Fluoride molten-salt electrolysis combines high temperature, aggressive corrosion and high current. This article breaks molybdenum forms down by conductor bar, crucible and structural part, explains the causes of grain-boundary penetration, thermal-cycle cracking and interfacial corrosion, and gives the matching and acceptance points for larger cells.

Cold repair is the chance to examine the electrode system in full. The article gives a checklist across six areas: appearance and dimensions, threaded connections, water-cooling jackets and seals, electrode-opening brickwork, the power supply circuit and spare parts. It explains marking positions before withdrawal, applying the specified torque at reinstallation, and filing findings under immediate action or continued observation.

Trading in the molybdenum powder market is moderate, and deep-processing companies generally buy against orders. The article analyzes the relationship between powder supply, billet inventory and electrode processing, and explains how costs are controlled under order-based purchasing.

A log that records only a few current figures cannot support trend judgment. This article lists the fields an electrode operating log should fix, including per-electrode current and voltage, phase imbalance, glass melt temperature and level, and the three cooling water data sets, explains how to write four-element anomaly entries, and gives an approach to weekly summarization of key indicators.

Discoloration of the electrode surface does not mean scrap, but neither should it simply be ground and reused. The article distinguishes surface oxidation from in-service erosion by appearance, describes how diameter measurement at several cross-sections is used to estimate reduction per side, sets out the requirements for grinding and re-inspection, and gives the boundary conditions and record-keeping for the three decisions of continued use, downgraded use and scrapping.

Quotation gaps for molybdenum electrodes mostly come from chain losses between concentrate and finished product. This article explains the cost structure stage by stage, from concentrate pricing, roasting yield and powder reduction to billet route, sintering and machining yield, inspection and packing, with indicative cost shares and a loss-location comparison, plus four questions for breaking a quotation down.

In 2026, WeiBeam hosted a glass electric melting technical seminar, inviting glass producers, design institutes and furnace engineering experts to discuss all-electric melting adoption, electric boosting conversions and electrode selection and maintenance, and the path to energy saving and carbon reduction in furnaces.

Covering powder preparation, bag filling, the pressure schedule and post-stripping verification in the cold isostatic pressing of molybdenum crucibles, the article explains how wall-thickness uniformity and density distribution are controlled and gives executable checks for filling, pressing and body inspection, for use at the forming stage and in blank acceptance.

New electronic glass lines are being ignited one after another, and molybdenum parts for forehearths and channels have entered the trial sample stage. The article explains electronic glass requirements for temperature uniformity, the validation process for trial molybdenum parts, and how trial samples link up with volume supply.

Protection settings are not better for being tighter; what matters is layering. This article sorts out the sources and meaning of overcurrent, phase loss, earth fault, cooling water temperature and flow signals, explains how the equipment, process and safety layers divide interlock duties, gives principles for adjusting settings, and sets out the troubleshooting order when tripping is frequent.

When three-phase currents diverge, adjusting the power setpoint directly usually treats the symptom rather than the cause. This article sets out a troubleshooting sequence across instrumentation and power supply, connections and contacts, and electrode and melt condition, with notes on what to record for later review.

Recycling spent molybdenum electrodes is not only about sorting and packing; the weighing basis, quotation factors and settlement milestones also affect the final return. This article reviews the key steps of the commercial process to reduce handover disputes.
