Since silicon carbide is dissolved in molten iron rather than melted, it takes longer to enter the molten iron than FeSi. Due to the longer action time, the decay time increases. Therefore, in the case of ductile iron, many foundries have fo...

The airholes always appear in the casting and the surface layer, and the section is round, oval, waist, round, pear -shaped and needle -shaped. The big airhole often exists in isolation, and the small airhole is often in group or......

Silicon carbide is a compound consisting of one carbon atom and one silicon atom, with 70% silicon and 30% carbon (by weight). It was accidentally discovered by Edward G Acheson while making synthetic diamonds. Its original use was as an abr...

The chemical composition of ductile iron mainly includes five elements, carbon, silicon, manganese, sulfur and phosphorus. For some castings with special requirements on structure and performance, it also includes a small amount of alloying...

The purpose of gray cast iron quenching is to change the matrix structure, obtain the martensite structure, and improve the hardness and wear resistance of the casting,Anyang Huatuo Metallurgy has in the raw materials of gray cast iron......

Different spheroidization methods can be selected for the production of ductile iron, and the advantages and disadvantages of different spheroidization methods are different. Anyang Huatuo Metallurgy Co., Ltd in the spheroidizing agent...

There are different spheroidization methods to choose in the production of ductile iron,today Anyang Huatuo Metallurgy will introduce different spheroidization methods to you,the foundries can choose according to their production condition....

The chemical composition of 6063 aluminum alloy in GB/T5237-93 standard is 0.2-0.6% silicon, 0.45-0.9% magnesium, the maximum limit of iron is 0.35%, and the remaining impurity elements (Cu, Mn, Zr, Cr, etc.) are less than 0.1%....

Medium and low carbon ferromanganese is one of the important raw materials for stainless steel, high manganese heat-resistant steel, alloy steel, structural steel, tool steel and electric welding rod. ...

The hardness of white cast iron is high, it cannot be machined, and it is very brittle, so it is seldom used directly to manufacture machine parts, and needs to be processed by appropriate heat treatment process. ...

Cold cracking is the cracking caused by the local casting stress greater than the ultimate strength of the alloy when the casting is cooled to an elastic state after solidification. Cold cracks always occur in the parts that are subjected t...

Before producing castings, we always hope to be able to form at one time, but it often backfires. The castings produced have cracks. How did the casting cracks form? ...
