ZOZEN Boiler not only has advanced production technology and equipment, but also introduces many high-tech measuring and testing equipment, which provides a powerful guarantee for manufacturing high-quality products. In this video, the quality inspector of ZOZEN Boiler is re-inspecting the steel in the factory through spectral analysis instruments. Each atom has its own characteristic map. After spectral analysis, the quality inspector can ensure whether the raw materials meet the standards, and effectively control the boiler quality from the source.
Convection bank tubes connect the upper drum and lower drum in bi-drum boilers. These bank tubes not only act as raisers and down comers between the drums but also carry the weight of the bottom drum in the case of top drum supported boilers.
In order to improve employees' awareness of safety in production, ZOZEN Boiler has adopted a safety education system, which is divided into three levels: factory level, workshop level and team level. At the daily team meeting, the team leader takes safety production as an important meeting content to publicize, further clarifies the responsibility for safety production, to improve the safety awareness and sense of responsibility of employees, and to avoid accidents in production. Welding in limited space is a common work environment for ZOZEN workers. Therefore, the frontline workers will dress well with the protection masks and long-sleeve overalls.
Boiler drum is one of the important components of boiler body, and its manufacturing requirements are strict. As a powerful boiler manufacturer, ZOZEN Boiler introduced advanced plate rolling equipment while standardizing the plate rolling process, to ensure better quality of the boiler drum. In the modern workshop of ZOZEN Boiler, the steel plate after pretreatment such as derusting, milling and chamfering will be transported to the drum workshop, and then rolled into the workpiece for manufacturing drum by the advanced four-axis numerical control bending machine.
ZOZEN Boiler is a professional manufacturer of industrial boilers in China. ZOZEN Boiler entered the boiler industry in 1988 and took root in the boiler industry, always taking manufacturing high-quality boilers as its responsibility. Through the wonderful video, we recorded the ZOZEN people who work hard in the front line of production. They always adhere to the quality and create ZOZEN good-quality boiler products. After years of development, ZOZEN Boiler has won a good market reputation by virtue of its reliable quality and perfect service.
ZOZEN full-automatic circular saw machine is mainly used for cutting steel pipes before bending. This full-automatic circular saw machine adopts automatic control, and the operator only needs to input the parameters such as material size and processing quantity, and the system will automatically adjust the complex parameters such as saw blade speed and feed rate (cutting speed) per tooth , to automatically produce the required steel pipe parts.
Welding is a vital work in the process of boiler manufacturing, and it has an important influence on the quality of the boiler. In the production base of ZOZEN Boiler, a professional boiler manufacturer, the front-line welders always ensure the quality of the boiler welding seams with their superb technology and responsible attitude. At the same time, ZOZEN Boiler has introduced the advanced welding equipment to realize the welding automation of the main components such as drums, membrane walls, serpentine tubes, steel frames, etc.
Heat treatment is an essential part of the manufacturing process, involving heating a metal or alloy to a specific temperature and then cooling it to harden the material. In the manufacturing process of boilers, the following pressure components require post-weld heat treatment: alloy steel pressure components and carbon steel pressure components which include butt joints with wall thickness greater than 30mm, the cylinders of internal combustion boilers, and T-joints with tube sheet wall thickness greater than 20mm. As a professional industrial boiler manufacturer, ZOZEN Boiler always strictly follows the boiler safety technical specifications to conduct heat treatment on specified boiler components, which effectively reduces the residual stresses in the material that have been introduced by welding and improves the boiler performance.
