Production Process
1. For the mold test of high-density teeth and large tongue ratio, the first aluminum rod must be a short aluminum rod or a pure aluminum rod of 150-200 mm.
Second, before the test, the extrusion center must be adjusted, and the extrusion shaft, the ingot cylinder and the mold base discharge port are on a center line.
Third, in the test mode and normal production process, the heating temperature of the aluminum rod should be guaranteed between 480-520 °C.
4. The heating temperature of the mold is controlled at 480 °C according to the temperature of the conventional mold. The flat mold holding time of the diameter below 200 mm shall not be less than 2 hours. If the split mold is kept for more than 3 hours, the mold insulation with a diameter greater than 200 mm shall be 4-6. Hours to ensure uniformity of mold core temperature and external temperature.
5. Before the test or production, the cylinder liner must be cleaned with a clear cylinder gasket, and check whether the extruder is running normally.
6. When the test mode or the beginning of production, the automatic cutting of the extruder is turned off, and the switches of each segment are returned to zero. Starting from the minimum pressure, the discharge is about 3-5 minutes, and the pressure is mainly controlled during the aluminum filling process. The pressure is controlled within 100Kg/cm2, the ammeter data is within 2-3A, generally 80-120Kg/cm2 can be discharged, and then slowly accelerated. The normal extrusion speed is less than 120Kg/cm2.
7. In the mold or production process, if the mold is found to be blocked, the teeth are too small, and the deviation is too fast, the machine should be shut down immediately, and the mold should be unloaded to avoid scrapping the mold.
8. In the test mode or production process, the discharge port must be unobstructed, and the pad support or the clamp looseness should be reasonably mastered according to the discharge condition. Observe the abnormal situation at any time and deal with it in time. Stop the machine immediately.
Nine, in the straightening process, it is necessary to carefully test the changes before and after, the operation specifications, moderate force, and strict product quality.
10. According to the production plan, a reasonable length is required. When sawing, the sawing feed speed should not be too fast, avoiding hurting the end, and the end must be clamped to remove the flash and burrs.
XI. Packing should be standardized, including the mats should be placed reasonably to avoid damage to the profiles.
12. The aging temperature of the profile is controlled at 190±5°C, the temperature is kept for 2.5-4 hours, and air cooling is performed after the furnace is discharged.

National Standard of the People's Republic of China GB/T 13754-92
Industry Standard
The Announcement No. 10 of the Ministry of Construction of the People's Republic of China on the Promotion of the Application of New Technologies and Products for Residential Buildings expressly states:
(1) Gray cast iron long wing radiator is limited to use.
(2) Elimination of the gray cast iron garden wing radiator.
(3) Elimination of gray cast iron 813-shaped radiator.
Local standard
2 The Tianjin Municipal People's Government Heating Office and the Industry Management Office jointly issued a document stating that new buildings for cooling systems and old buildings for cooling systems must use non-cast iron radiators, and aluminum radiators with anti-corrosion can be used.
3 Liaoning Provincial Construction Department Document (Liao Jianfa [1998] No. 76) "Notice on Promulgating the Prohibition, Restriction and Non-Provision of Use Technology and Products of Liaoning Province Construction System" clearly stipulates: Gray cast iron 813 radiator in all construction projects Restricted use and the elimination time is 2000 years.
Function description
1). Function: Increase the air flow rate and flow rate through the radiator to enhance the heat dissipation capacity of the radiator and cool the engine accessories.
2). Installation position: The fan is mostly axial flow type, installed between the engine and the radiator, and is driven coaxially with the water pump. The fan is screwed onto the pulley or flange of the front end of the pump shaft.
3). Fan fan air volume related factors: fan fan air volume is mainly related to fan diameter, speed, blade shape, blade mounting angle and number of blades.
