The magnesium-zirconium flow liquid hole cover plate brick is made by magnesium-zirconium refractory material and is a key Block used to cover and protect the flow liquid hole of the glass kiln.   Main parameter: ·High temperature: used for a long time at temperatures above 1500  ° C   ·Chemical erosion: Subjected to continuous and high-speed erosion and penetration by the highly alkaline molten glass liquid.   Temperature fluctuation: Under conditions of kiln cooling, heating, or unstable working conditions, it will endure thermal shock.   ·Mechanical stress: Experiencing pressure from the upper kiln structure and the flow stress of the glass liquid.   ·Gas phase erosion: The alkali vapor (R₂O) in the kiln atmosphere will condense and erode the bricks.   Magnesium-zirconium bricks, due to their unique properties, have become the preferred or essential materials for modern high-performance glass kilns, especially for non-alkaline glass, electronic glas...

In 2025, the industrial manufacturing sector is facing an unprecedented challenge in terms of raw materials.   Due to the combined effects of environmental protection production restrictions, tightened mining quotas (with tungsten ore quotas expected to decrease by approximately 6.45% in 2025 compared to the previous year), and the growth in downstream demand from sectors such as photovoltaics and military industry, the price of tungsten concentrate has risen by nearly 80% this year, reaching a new high in the past decade. Meanwhile, the export restrictions on tungsten-related products have become stricter, putting pressure on enterprises that rely on tungsten steel (hard alloy) for manufacturing tools, wear-resistant parts, and molds, as they are confronted with both cost and supply issues.   Against the backdrop of continuous price hikes of tungsten steel and increasing supply uncertainties, finding mature and reliable alternative materials for tungsten steel has become an u...

In a vacuum environment, the pivotal conduit for secure energy transmission.  Vacuum electrical power feedthrough is a key through component specially designed for vacuum systems. Its core function is to safely and reliably transfer electrical energy from the atmospheric environment to the vacuum interior while absolutely maintaining the vacuum seal of the cavity. It is the indispensable “energy link” that connects the external power source with the internal load of the cavity.   This component has solved the core problem of stable power supply under high vacuum conditions, and is the foundation for the reliable operation of various heating, high-voltage, and particle beam processes.     Design core: Sealing, insulation and current carrying capacity   The design of vacuum electrical power feedthrough is centered around three core aspects: sealing, insulation, and current-carrying capacity.   (1) Based on the mature ceramic-metal brazing technology, an atomi...
