An iron stand is placed in each tank and placed in the center of each treatment tank. The length of the iron frame is 80 to 100 cm, the width is 80 to 100 cm, and the height is 30 cm. Degreasing, phosphating tank of the iron frame length of 260 ~ 320cm, width 80 ~ 100cm, height 30cm. Pure water, rust-proof oil of stainless steel frame length of 80 ~ 100cm, width of 80 ~ 100cm, height of 30cm.

Note: pickling, blackening, reaction, the table does not place the trough.

2, the tank material: non-heated groove to acid plastic plate for the material. Such as pickling, blackening, reaction, table tone, washed, pure water wash. The heated tank is made of stainless steel or carbon steel. Such as degreasing, phosphating, anti-rust oil. The hot water tank must be made of stainless steel plate.

3, wash the water tank to wash the way to overflow. That is, the latter part of the water tank to fill the water, the water pipe directly into the bottom of the tank, the use of liquid level difference and then into the front wash tank, and finally into the ditch. And the air pipe is placed at the bottom of each washing tank, causing agitation to increase the washing effect.

Note: the effect of washing and quality is proportional to the relationship, must not be ignored. The normal handling of 1 ton of screws to spend 2.5 to 3 tons of water.

4, steam heating is necessary, the boiler steam pressure to ensure that. Degreasing 80 ~ 90 ℃, phosphating 85 ~ 90 ℃, anti-rust oil 45 ~ 55 ℃.

5, the steam pipe after the hot water can be placed into the back of the water tank used. That is, the degreasing tank into the degreasing after the second washing tank, phosphating the tank into the phosphating after the second washing tank, hot water, rust-proof oil tank into the phosphating after the second washing tank. This action can improve the quality.

6, the daily work, you must determine the temperature of the pickling tank at least 40 ℃ or more. You can use the steam pipe to heat directly, when the temperature reaches the immediate removal of the steam pipe. If the pickling is bad, it will directly reduce the quality of phosphating.

7, if you want to speed up the degree of drying oil, in addition to the choice of more quick-drying rust-proof oil, but also must be in the top of the centrifuge to hot air into, especially when the outdoor temperature is low.

8, with particular attention to carburizing heat treatment process, which in the pickling of the project can be very clear to know. Non-standard carburizing heat treatment process, the phosphating treatment caused a great burden, and even lead to failure of bitter fruit
