FAQ

Q1: What is the maximum working temperature of a glass baking tunnel oven?

A:The working temperature of standard glass baking tunnel ovens is generally between 80°C and 300°C. Special high-temperature sintering models can be customized to reach temperatures above 600°C.

Q2: How does the equipment ensure temperature uniformity inside the oven?

A:The equipment uses upper and lower or side hot air convection circulation systems, combined with multi-zone independent temperature control and optimized airflow guide hole designs, to achieve uniform heat distribution throughout the furnace chamber.

Q3: What conveyor belt materials are available?

A:Common conveyor options include:

Stainless steel mesh belt — Suitable for high-temperature applications and strong load requirements

PTFE (Teflon) mesh belt — Provides excellent non-stick performance and chemical resistance

Graphite plate conveyor — Suitable for special high-temperature glass processing applications

The selection depends on the glass size, weight, production requirements, and processing temperature.

Q4: How are exhaust gases generated during baking treated?

A:The top of the furnace is equipped with exhaust ducts, which can be connected to factory exhaust treatment systems, such as:

RTO (Regenerative Thermal Oxidizer) systems

Activated carbon adsorption units

The exhaust gases are purified before being discharged to meet environmental protection requirements.

Q5: What maintenance is required for daily operation of the equipment?

A:Daily maintenance includes:

Regularly cleaning impurities and residues inside the furnace

Checking the condition of heating tubes and the sensitivity of thermocouples

Lubricating transmission bearings

Calibrating and verifying temperature control curves
