耐火物貯蔵の一般的な問題とソリューション

耐火物は高温産業分野で広く使用されています, 冶金などの, 建築資材, 化学薬品, そして電力. その性能は装置の耐用年数や生産効率に直接影響します。. しかし, 耐火物を不適切に保管すると、耐火物が湿気を帯びる可能性があります, 酸化した, ひび割れた, パフォーマンスが低下する, thus affecting construction quality and even increasing costs.

Common problems and cause analysis

Castables, スプレーコーティング, and refractory clay agglomerate due to moisture

Problem manifestation: Powdered or wet materials such as キャスタブル and refractory mud are prone to moisture and agglomeration during storage, affecting construction performance and even causing inability to use.

Possible causes

The storage environment is humid and the air humidity is too high

The packaging is damaged, causing water vapor to penetrate

Storage time is too long and exceeds the shelf life

Refractory bricks crack or fall off

Problem manifestation: 耐火レンガ may crack, fall off, or even break during storage, affecting construction and use.

Possible causes

Repeated changes in wetness and dryness after moisture damage, resulting in structural damage
Improper stacking method, resulting in excessive pressure on refractory bricks
Excessive temperature difference, resulting in thermal stress damage

Moisture absorption and deformation of ceramic fiber products

Ceramic fiber problem manifestations: Ceramic fiber blankets, ceramic fiber boards, and other materials may deteriorate in performance or even deform due to moisture absorption during storage.

Possible reasons

Storage environment humidity is too high, and unsealed packaging
External compression, unreasonable storage method, product moisture absorption, and deformation

Silicon carbide products and magnesia carbon bricks are oxidized

Problem manifestation: Carbon-containing materials such as silicon carbide products and magnesia carbon bricks may be oxidized during storage, affecting their fire resistance.

Possible causes

Long-term exposure to air, reacting with oxygen and moisture
The storage environment humidity is too high, causing the material to gradually oxidize

Refractories react with other chemicals

Problem manifestation: Some refractory materials may undergo chemical changes during storage due to contact with acids, アルカリ, oils, および他の物質, affecting their performance.

Possible reasons

The storage location is close to chemicals and is contaminated
No effective isolation measures are taken
