Bogie Hearth Furnace 1200°C with five heating sides

Overview

Bogie Hearth Furnace also known as car bottom furnace, which comprises a trolley car and a furnace body, mainly for annealing and quenching or hardening larger parts such as cast parts or tool steel dies or semiconductor dies to temperatures between 800 °C and 1100 °C, the furnace heating in the way of radiation from 5 heating sides, so the temperature balance at each angle, including the bottom. Programtherm provides a wide range of bogie hearth furnace with capacity up to 2000L, Tmax 1400°C. 

Main Features

• Tmax 1200 °C
• Self-supporting and long-life ceiling construction with bricks laid in arched construction
• Manual trolley car bottom, bogie hearth type heat treatment furnace for industrial (automatic is optional)
• Loading capacity ranges from 300kgs to 1 ton as per needs
• Three zones control for optimal temperature uniformity, each zone controlled independently
• Multi-layer insulation consisting of high alumina lightweight mullite bricks backed by fiber board insulation
• Heating elements mounted on ceramic tubes provide for free radiation and long service life
• Heating from five sides provides for a optimum temperature uniformity
• Bogie heating receives electric power via blade contacts with rear side when driven in, bottom heating protected by Silicon carbide board on the bogie providing level stacking surface.
• Bogies with flanged wheels running on rails for easy and precise movement of heavy loads
• Motorized exhaust air flap for optimum ventilation of the furnace chamber and for rapid cooling at low temperatures
• Precise Shimaden PID controller with programmable 32 segments
• CE certified, standard

Safety Measures

• Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
• Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller's manual) or when the thermocouple is broken or malfunctions
• Power failure protection resumes furnace operation right after the point of failure when power is reestablished
• Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot

Application Notes

• However, toxic or explosive gases that may generate from the sample during the heating are not recommended for use with this programmable muffle furnace without necessary safety controls and supervision.
• Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating
