不鏽鋼鑄件砂型選擇砂在不鏽鋼鑄件的生產是非常重要的,在砂子的選擇和使用上也是具有一定要求的。常用的一般有以下幾種:
Sand is very important in the production of stainless steel castings, and it is also required to choose and use sand. Commonly used:
不鏽鋼鑄件生產中的重點部分就是砂處理部分,顧名思義就是處理幹砂,選擇這幾種砂子本身塵埃就少,效果自然就會好,特別是寶珠砂,還有就算暫時沒有砂處理,人工涼砂除塵的話,也相對比較便捷點。不鏽鋼鑄件常用幹砂一般為水洗石英砂,海砂,和寶珠砂,粒度一般在20目到40目,主要是根據它的耐火程度,也就是含矽量不能低於95%,再就是從他的透氣性能而選擇的,前兩種砂子適合一般鑄件,比較經濟。
Stainless steel castings in the production of key parts is sand processing, just as its name implies is to deal with dry sand, choose this several sand dust itself, the less effect will naturally good, especially miss glistening sand, and even temporarily no sand processing, artificial sand dust, cold also is relatively convenient point. Stainless steel castings commonly used dry sand washing quartz sand, sea sand, sand and orb, granularity in 20 to 40 mesh, mainly according to its fire-resistant degree, which is not less than 95% silicon content, and from the permeability of his choice, the first two sand for casting commonly, more economic.
寶珠砂屬於人造砂,性能比較好,比較耐用,隻是價格上要比普通砂子高四至五倍,一次性投入成本會比較大,但是長期使用下來因為他損耗率低的原因,無論實在成本上還是鑄件質量上都要優於普通鑄造用砂。
Treasure sand belongs to artificial sand, performance is better, more durable, just price is four to five times greater than the ordinary sand, one-time cost will be big, but the long-term use of down because of his reasons for the low attrition rate, no matter it cost or on the casting quality is better than ordinary foundry sand.
在不鏽鋼鑄件的鑄造行業,夾砂和砂眼是經常會在生產中碰到的問題,為什麽會出現這樣的問題呢?
In the casting industry of stainless steel castings, sand and sand eyes are frequently encountered in production. Why is such a problem?
除了清砂不當外,如果設備使用之前存在沒有完全的處理幹淨,或是在不鏽鋼鑄件在澆注的過程中,由於澆注的溫度過高,鐵液衝刷澆道壁的型砂,也會出現夾砂和砂眼的問題。起初,由於對這方麵的要求不嚴格,並不影響使用,因此各個廠家都不太重視這樣的問題,有些廠家為了緩解這樣的問題,通常就是采用塗刷塗料來解決,但是因為這樣的過程也比較辛苦困難,因此還是會導致鑄造出來的鑄件會存在夾砂與砂眼的現象,很大的降低了鑄件的質量。
Besides improper deoxidization, if equipment is not clean enough, before using or in stainless steel castings in pouring process, as a result of the pouring temperature is too high, liquid iron scouring sprue wall of sand, also can appear sand and sand holes. At first, because of this requirement is not strict, does not affect use, so each manufacturer are not pay attention to this problem, some manufacturers in order to alleviate this problem, is usually besmear brushs paint is used to solve, but hard because this process is more difficult, so will lead to cast castings will exist the phenomenon of sand and sand holes, reduce the quality of the castings.
為了解決鑄件中出現的夾砂和砂眼問題呢?經過不斷的研究發現,隻要采用專用鑄造塗料進行內壁的清理保護,就可以大量減少夾砂和砂眼的問題,而且對提高鑄件的成品率也有很大的作用。
In order to solve the problem of sand and sand in casting? After constant study found that, as long as using special casting coating for inner wall of cleaning protection, can significantly reduce sand inclusion and the problem of sand holes, and also have a role to improve the yield of castings.
不鏽鋼鑄件在長期使用中,受外界環境的影響,掉漆屬於正常現象,這時候ag8亚游就要進行補漆。
In the long-term use of stainless steel castings, it is normal to drop the paint due to the influence of the external environment.
1、首先ag8亚游應當準備修補所使用的工具:砂紙、刷子、噴漆或者是桶漆,選擇油漆的時候應當盡量選擇防鏽油漆或者是聚酯型的麵漆,還應當要保證不鏽鋼鑄件的塗刷的次數在兩次以上。需要將生鏽位置的鏽斑用砂紙打磨幹淨。
1, first of all, we should be ready to repair the use of tools, abrasive paper, brush, spray painting or a bucket of paint, should choose as far as possible when choosing paint antirust paint or polyester paint, also should be to ensure that the stainless steel castings besmear to brush the number of times in more than two times. The rust spot that needs to rust place is sanded clean with sandpaper.
2、使用油漆進行第一次的粉刷的時候應當盡量粉刷均勻,待油漆幹透之後再進行第二次的粉刷,第二次進行塗刷的時候應當使用聚氨酯型麵漆,塗刷的時候應當盡量保證表麵光滑。
2, use the paint for the first time shall be painted even, to paint dry before the second, the second time type should be used in polyurethane paint coating, should try to ensure that the surface is smooth when brushing.

 
3、若不鏽鋼鑄件的老化情況比較嚴重的時候,應當盡量考慮更換新的
3. If the aging situation of stainless steel castings is serious, we should try to replace it
