Anti-deviation Stabilizing Roller High-precision Positioning and
Stabilizing Furnace Rollers For Glass Production Lines
Furnace Rollers:
Furnace rollers are core functional components used to carry and
transport high-temperature materials in industrial furnaces (such
as heat treatment furnaces, annealing furnaces, and glass melting
furnaces). Their performance directly determines production
continuity, material processing quality, and equipment efficiency.
They are widely applicable to high-temperature industrial
applications such as steel, glass, ceramics, and non-ferrous
metals.
Material Transport: Through rotational motion, they smoothly transport materials such
as steel plates, raw glass sheets, and ceramic bodies to the
heating, annealing, and cooling areas within the furnace, ensuring
continuous production.
Operating Conditions: They are exposed to high temperatures of 400-1200°C (up to 1500°C
in some applications), and must withstand the weight of the
materials, thermal shock, and corrosive gases within the furnace
(such as oxidizing atmospheres and sulfur-containing gases). In
some applications, they also require auxiliary temperature control
(e.g., cooling with water-cooled rollers or supplementary heating
with electrically heated rollers).
Quality Assurance: The flatness, roughness, and thermal stability of the roller
surface directly impact the surface quality of the material (e.g.,
no indentations on steel plates or scratches on glass) and uniform
heating.
Furnace rollers are often composite structures, with the following
core components:
Roller Sleeves: The outer layer of the roller that directly
contacts the material and must exhibit high wear resistance,
anti-adhesion properties, and high-temperature oxidation
resistance. Common materials include heat-resistant steel,
high-nickel alloys, or ceramic coatings.
Core Shafts: The inner layer of the roller sleeve that supports the roller
sleeve and transmits rotational power. These shafts must provide a
balance of strength and heat resistance. Some applications (such as
high-temperature furnaces) may utilize hollow structures to allow
for the passage of cooling media (e.g., water or nitrogen).
Support Components: These include bearings and seals, which must maintain lubricity
and sealing properties even in high-temperature environments to
prevent furnace gas leakage and dust from entering the bearings.
