Jiangsu Jiuding Industrial Furnaces Technology Co., Ltd. is one of the most experienced manufacturers and suppliers of trolley annealing furnace in China, also supports customized service. Welcome to wholesale high-grade trolley annealing furnace for sale here from our factory. Quality products and reasonable price are available.
Product Concept

The trolley annealing furnace is a national standard energy-saving periodic operation furnace with an ultra-energy-saving structure and a full-fiber furnace structure, saving 30% of electricity. Exclusively produced with a composite high-aluminum porcelain nail set, trolley anti-collision sealing bricks, automatic sealing trolley and furnace door, integrated rail connection, no foundation installation required, and can be used on a horizontal ground. It is mainly used for quenching, annealing, aging and heat treatment of various mechanical parts such as high-chromium and high-manganese steel castings, ductile iron, rollers, steel balls, 45 steel, stainless steel, etc.
Product Features
1. No noise, no environmental pollution.
2. Small heat storage and less heat loss.
3. High temperature control accuracy and strong furnace temperature uniformity.
4. High degree of automation and simple operation.
5. PID programming can be used for full automatic execution.
6. Good sealing, long life, safe and reliable.
Product structure
It mainly consists of the furnace body (including furnace door), furnace lining, furnace door lifting and sealing device, furnace car, furnace car transmission mechanism, electric heating device, temperature control and recording system and other main parts. No foundation installation is required, and it can be used by placing it on a level ground.

Note: The heat-resistant steel furnace bottom plate installed on the trolley is used to carry the workpiece. In order to prevent the oxide scale generated after the workpiece is heated from falling into the bottom heating element through the gap of the furnace bottom plate and causing damage to the heating element, regular maintenance and blowing of the oxide scale under the trolley furnace bottom plate are required. Blowing away the oxide scale can ensure long-term trouble-free use.
Our company can design and manufacture trolley annealing furnace of various furnace sizes and models for users according to user needs.
