You should never think that the refrigerated trucks you see every day are the same, that is, the refrigerated compartments are installed on the chassis of different brands of trucks. In fact, according to the different temperature requirements of the transported goods, the functions of the refrigeration unit are different, and the country also clearly defines the corresponding category distinction. Classification of refrigerated trucks: According to "Safety requirements and test methods for road transport, food and biological products refrigerated trucks" (standard number: GB 29753-2013), the classification of refrigerated trucks has eight levels from A to H. This standard was implemented in 2013. It was not mandatory to spray the markings on the carriages. Afterwards, with the strict implementation of the regulations, it has become a mandatory project. All refrigerated trucks must spray refrigerated trucks in obvious positions. According to GB requirements, the eight levels of refrigerated trucks belong to two major categories: Vehicles that transport articles are perishable foods (divided into AF) vehicles that transport biological products (in categories G and H). When the ambient temperature is 303K (30 °C), the temperature range maintained by the average temperature of the refrigerated truck will be Refrigerated vehicles for perishable foods are classified into AF, Category 6, and are classified as follows: AF class When the ambient temperature is 303K (30 °C), the refrigerated trucks transporting biological products are classified into GH, Class 2 according to the temperature range maintained by the average temperature of the refrigerated truck compartment. GH class This is the classification standard for refrigerated trucks. You can use the above criteria to compare the grades of your refrigerated trucks. Currently, most refrigerated trucks on the market are made in accordance with B and F refrigerated trucks. Only some fresh refrigerated trucks are Made according to Class C standards. According to such standards, users can also choose a suitable refrigerated truck according to the needs of their daily transportation of goods.

Continuous annealing furnace with furnace roll
Make various types of roller from small diameter (60mm) to large diameter (1600mm). In particular, the large diameter Furnace Roller used in continuous annealing production line with higher reliability is highly appraising. In addition, it also produces special roller for measuring temperature and equalizing temperature.
High speed wire rod mill at home, at the wire rolling mill, rod line and use of roller slit rolling mill ring, due to the work under the roll ring in relatively poor thermal conditions, therefore must be able to withstand the wear and corrosion of cooling water and the big rolling torque and so on, at present a lot of manufacturers adopt tungsten carbide tungsten carbide roll rings, but because the cost of tungsten carbide roll ring manufacturing high, caused the enterprise production costs rise, and in view of the actual situation, our factory successfully developed special wear-resistant alloy MSW66552 series, nearly half of the manufacturing cost is tungsten carbide, the effect of using basic tungsten carbide. The e product has been confirmed by the user, MSW66552 alloy product hardness 88HS, roll surface hardness difference less than 2HS, 6000C red hardness more than 82HS, roll body radial 30mm hardness difference less than 3HS, impact toughness more than 15J/CM2, fracture toughness more than 60Mpa. M1 /2.
