FAQ

Q1: How many temperature zones is the 80-meter foaming furnace usually divided into?

A1: It is usually divided into 16–20 independent temperature zones. Each section is independently temperature controlled to meet the process temperature curves required for material heating, foaming, and shaping.

Q2: What requirements does this equipment have for factory building span and height?

A2: The factory length should be greater than 95 meters to provide sufficient space for feeding and discharging sections. The recommended clear height is above 4.5 meters, and the floor should be leveled and hardened.

Q3: How does the equipment solve the problem of thermal expansion caused by the ultra-long furnace body?

A3: The furnace body is designed with professional mechanical thermal expansion compensation structures, ensuring that the equipment does not shift or deform during high-temperature expansion.

Q4: How are the exhaust gases generated during the foaming process treated?

A4: Multiple exhaust outlets are installed on the top of the furnace body and connected to a centralized exhaust fan. The system can be connected to factory exhaust gas treatment equipment such as regenerative thermal oxidizers (RTO) or activated carbon adsorption systems.

Q5: What are the key points for daily maintenance of this large-scale equipment?

A5: Regular maintenance includes checking the lubrication and tension of the transmission chains, cleaning residual materials inside the furnace, and calibrating the thermocouple temperature sensors in each temperature zone.
