Trolley Annealing Furnaces For Pressure Vessel Components

This series of trolley-type pressure vessel annealing furnace is a new, energy-saving and environmentally friendly heat treatment equipment advocated by the state. It has an ultra-energy-saving structure and is mainly used for pressure vessel welding parts, spherical tanks, heads, flanges, and other mechanical products to eliminate welding stress and anneal. This series of products has the advantages of good safety, excellent energy saving effect, good temperature uniformity, etc., and can replace the traditional refractory brick lining trolley furnace in the heat treatment industry.

1. The equipment composition of the trolley-type pressure vessel annealing furnace:

The furnace is mainly composed of furnace body (including furnace lining), furnace car and traveling mechanism, furnace bottom plate, furnace door and furnace door lifting system, hot air circulation system, air guiding system, electric heating device, sealing device, touch screen temperature control and recording system, Main components such as power system and motion control system

2. Features of trolley-type pressure vessel annealing furnace:

• This series of trolley-type pressure vessel annealing furnaces have introduced foreign advanced technology. The furnace types include trolley-type pressure vessel annealing furnaces, variable-capacity trolley-type pressure vessel annealing furnaces, gas trolley-type pressure vessel annealing furnaces, and pit-type pressure vessels. Various furnace types such as annealing furnace, this series of furnace types adhere to the characteristics of high performance and high degree of automation of European industrial furnaces;

The lining of the trolley-type pressure vessel annealing furnace is built with new energy-saving zirconia ceramic fiber module materials as a whole, which saves 15-30% compared with the traditional furnace type and has a service life of 5-8 years;

The heating element of the trolley-type pressure vessel annealing furnace is made of high-temperature and high-resistance electric heating alloy tape wound into a wave shape. The surface load can reach 1.6~2.0w/cm2, and the service life can reach 8~10 years. 2-3 times longer lifespan;

The trolley type pressure vessel annealing furnace trolley, furnace body and furnace door are sealed with a four-bar linkage mechanism and an electric cylinder side pushing and tightening double sealing mechanism, which has high sealing performance and reduces energy loss;

• The bearing part of the trolley-type pressure vessel annealing furnace trolley is built with high-strength and high-aluminum heavy bricks.
• The furnace body of the trolley-type pressure vessel annealing furnace is integrated with the trolley. The equipment can be directly fixed on the ground plane and used, and the installation is simple.

The trolley-type pressure vessel annealing furnace adopts the latest industrial automation control technology, which perfectly combines the instrument, probe, monitoring and action, and the convenient man-machine interface can realize manual and automatic operation;

• Multi-user authority management, different users have different authority levels and their operation restrictions are also different;
• Current, voltage, electricity monitoring technology, different shift monitoring of electric energy and cost statistics report;
• Touch screen operation, intuitive display of various parameters, simple operation, real-time recording of various curves and data;
• Electric heating multi-zone synchronous control technology, one-key operation of the furnace again, the whole process is recorded, and it is completed automatically and efficiently;
• Multiple time curves can be set, and the total number of curve segments can be up to 50 segments;
• There are two program setting modes of “given value + time value” and “heating section + constant temperature section”;

3. Full fiber low temperature trolley furnace safety protection:

• Over-temperature alarm system: when the temperature in the furnace changes abnormally, it will issue an audible and visual alarm, and automatically cut off the heating power;
• Interlock protection of furnace door and trolley transmission: that is, open the furnace door before starting the trolley;
• Support to turn off the output when the furnace door switch is disconnected;
• Motor overload protection: prevent the motor from burning and tripping;
• Electrical heater short-circuit protection: to prevent the electric heater from being burnt due to short-circuit;
• Control circuit protection: prevent circuit short circuit and cause accidents;
• Circuit breaker: prevent the main circuit from being overloaded and short-circuited, causing accidents;
