Advanced lathe processing C93200 wear-resisting bronze half bearing bushing
Slag inclusion in copper casting of crusher: Defects caused by inclusion of molten slag in molten metal without timely separation occur during pouring. Sand holes: Because of the defects formed by the inclusion of sand fragments in the molten metal, it probably existed before the molten metal entered the cavity, and in some cases formed by sand washing during casting. Both of the above defects belong to inclusion defects. Porosity: Formal scientific name should be shrinkage, which is a honeycomb defect caused by insufficient shrinkage during solidification of liquid metal; shrinkage hole: shrinkage hole should be more serious, that is, shrinkage has concentrated into one or several larger holes, the upper part of shrinkage hole usually accompanied by shrinkage zone. Pinhole: Actually, it is a needle-like stomata, which can be divided into many kinds according to its formation mechanism. The latter three kinds of defects are void defects, that is, there is no inclusion in the defects. Sometimes, because the slag or sand contains gaseous substances, there will be slag pore phenomenon.

Products are widely used in textile machinery, injection molding machinery, mining machinery, construction machinery, automotive industry and other fields. The company can choose a variety of brands from China, Germany, Japan, the United States and other countries to make copper bushings, gaskets, skateboards, half-tiles and other products. It can process various oil tanks and injection holes on its inner and outer walls according to customers'requirements. It can also be processed by drawing.
Standard and Selection of Copper bushing
According to different product standards of copper sleeve, it can be divided into self-lubricating copper sleeve, oil lubricating copper sleeve, graphite copper sleeve and so on. Raw materials for copper bushing are also common: tin bronze, aluminum bronze, brass, phosphorus bronze, etc. Casting methods are further divided into: metal casting model, precision casting, centrifugal casting, sand casting.
copper bushings are made of the following materials:
C92700
High hardness, excellent wear resistance, not easy to produce bite, good casting and cutting performance, in the atmosphere and fresh water has good corrosion resistance. It can be used for wear parts with high load (less than 20Mpa) and high sliding speed (8m/s), such as connecting rod, bushing, bushing, gear, worm wheel, etc.
C83600
Corrosion resistance, especially for dilute sulfuric acid, hydrochloric acid and fatty acid. Structural materials, corrosion and acid resistant fittings and crusher bushing and bushing.
C93700
It has good lubricity, wear resistance and corrosion resistance, and is suitable for bimetallic casting materials. Automotive bearings, bimetal bushing of internal combustion engine with peak load up to 100 MPa, piston pin bushing, friction disc, etc.
C93800
In the absence of lubricants and water-based lubricants, it has good sliding and self-lubrication, easy cutting, poor casting performance and good corrosion resistance to dilute sulfuric acid.
Bearings with high surface pressure and side pressure can be used to manufacture copper cooling tubes of cold rolling mills, parts with impact resistance up to 50 Mpa, bimetallic bushing of internal combustion engines, mainly for piston pin sleeves with maximum load up to 70 Mpa, acid-resistant parts.
Casting Conditions
The melting point of copper castings in crusher is a complex problem, including the purity of copper, ambient air pressure and so on. Therefore, there will be different data. The melting point of pure copper is 1083.4 (+0.2 C). But usually the copper we use is alloy (pure copper is too soft, no application value), so there are different temperatures! But roughly all within this range! Industrial temperatures are generally much higher than the melting point to melt it! So this data has no practical value, just for reference! It's meaningless not to take an exam.
