Rust--metal corrosion; great loss to mechanical manufacturing; unique F fine parts such as bearing products ç°¦; rusting; not only affects accuracy and appearance roughness; and reduces service life; even obsolete and can not be used. Bearing anti- Rust operation F an important operation; anti-rust between the unique F process; like the bearing in the heat treatment workshop after pickling, cleaning, grinding processing; there are many processes. When the product is not F used to produce water; one order of processing At the end, it should be stored in the central warehouse; therefore, it is necessary to carry out rust prevention when storing the bearing rings between the processes. The conventional rust prevention methods and the lack of anti-rust between the bearing processes are generally selected as follows: 1. Dip in the anti-rust tank to immerse the bearing in 5% sodium nitrite and 0.6% sodium carbonate aqueous solution; the anti-rust effect is good; but many anti-rust tank equipment; take up a lot of space; handling is not convenient. 2 . After dip coating concentrated sodium nitrite solution to remove the product; immersed in 15%-20% sodium nitrite and 0.6% sodium carbonate solution; then stack it up. This method has a short rust prevention period; Usually only for 7-14 days; and in the rainy season; because the climate is humid; only 2-3 days can be re-processed; demand costs labor and money. The oil-coated products are coated with anti-rust oil. This method is necessary to remove before the next process; it is more complicated. The new anti-rust process analysis is conducted through joint research with related manufacturers; the production practice is marked for many years; The rust was repeatedly improved; the rust-proof rust-proof effect was better than that. The rust prevention of the roller was started. The semi-products and products were washed once a day with an aqueous solution of sodium nitrite; after 3 months, no rust was found in the test results; For the semi-products of the bearing scam, the rust-proof rust is used; the effect is also the same. The rust-proof rust-proof process is simpler; the method is as follows: 1. Equipment purchase and construction based on the storage of semi-products; establish a central repository; cement floor on the ground; a walkway can be set in the center; about 1.5 m; used to pass the bearing ring trolley. At the end of the channel, a tank of sodium nitrite solution is placed. The solution formulation is 5%-10% sodium nitrite plus 0.6% sodium carbonate; and the backwater drain is made on the ground; then the bearing rings are stacked on the two sides of the floor; The 0.6m walkway can be said to be about 64m2; the sodium nitrite aqueous solution pool is 1m3.2. The process is washed once a day with an aqueous solution of sodium nitrite; the aqueous solution is sucked from the pool by the water pump; the rubber pipe is passed to the shower head; the bearing ring is flushed like a shower. After the flushing, the aqueous solution flows back to the pool from the backwaters; The upper part of the water pool at the end of the ditch; use a fine wire mesh and gauze to make a filter net to infiltrate the textile ash and dirt into the pool. The central bank should be hygienic and hygienic. The pool solution should be tested every 2 days; it should be compensated according to the test results; the replacement period of the solution in the pool is different. It is carried out in the month; it is completely exchanged every 2 weeks from April to September; it is exchanged every month from October to March; the rust is sprayed on the rust; the convenience is convenient; the labor is saved; I can't finish the anti-rust. I can also do other work with one person. It is also obvious from the anti-rust effect. In March 2003, there were more than 4,000 rolls of 7002136 and 3620 rollers. Anti-rust; it has been very bright for nearly a year; there is no rust. In addition, it also saves a lot of chemicals; the roller workshop costs more than 4,000 kilograms of sodium nitrite per month; now only 200 thousandå…‹; saving nearly half. The spray-type rust-proof method has been tested and applied by related manufacturers in recent years; it proves that it is suitable for medium, large, batch and long-term bearing semi-products.
