    How to distinguish between gray cast iron and cast steel?

    How to distinguish between gray cast iron and cast steel? Gray cast iron carbon mainly crystallizes into graphite and exists in the form of flakes in cast iron, with dark gray fracture surface, making it a common cast iron component. The chemical composition of gray cast iron is generally 2.6%~3.6% C, 1.2%~3.0% Si, 0.4%~1.2% Mn, ≤ 0.3% P, 0.15% S. Cast steel is an important metal structural material with excellent comprehensive mechanical and physical and chemical properties. Compared with cast iron, cast steel has higher strength, plasticity, toughness, and good weldability. If you are referring to these two results, you can use a file to judge them based on their different hardness. You can first find a standard gray cast iron component and then use the same new file to file on the surface of both components. If it feels like the hardness of two pieces is the same, it is judged to be gray cast iron; If the file is judged to be slipping or noticeably harder than standard gray cast iron parts, it is judged to be cast steel.

  • The relationship and differences between cathode copper, anode copper, and 1 # electrolytic copper
    The relationship and differences between cathode copper, anode copper, and 1 # electrolytic copper

    Electrolytic purification of copper: Coarse copper (containing 99% copper) is pre made into thick plates as the anode, pure copper is made into thin plates as the cathode, and a mixture of sulfuric acid (H2SO4) and copper sulfate (CuSO4) is used as the electrolyte. After being electrified, copper dissolves from the anode into copper ions (Cu) and moves towards the cathode, After reaching the cathode, electrons are obtained and pure copper (also known as electrolytic copper) is precipitated at the cathode. Impurities such as iron and zinc, which are more active than copper, dissolve together with copper to form ions (Zn and Fe). As these ions are less likely to precipitate compared to copper ions, adjusting the potential difference appropriately during electrolysis can prevent these ions from precipitation at the anode. Impurities such as gold and silver, which are less active than copper, deposit at the bottom of the electrolytic cell The copper plate produced in this way is called "electrolytic copper" and has extremely high quality, which can be used to make electrical products. The sediment at the bottom of the electrolytic cell is called "anode mud", which is rich in gold and silver and is very valuable. It has extremely high economic value when taken out and processed Electrolytic copper=cathode copper

  • How many models of aluminum ingots are there
    How many models of aluminum ingots are there

    According to the national standard, aluminum ingots can be divided into 8 models according to their composition, AI99.90 85 70 60 50 00 7E. The general market demand is for standard aluminum AI99.70, with high-end requirements of 85, special requirements of 99.90, and even a few higher requirements.

  • What is difference between copper ingot machine and aluminium ingot making machine?
    What is difference between copper ingot machine and aluminium ingot making machine?

    As we know the melting temperature of aluminum scrap is much lower than copper's, so as same as the casting temperature, copper need higher temperature by die casting. Therefore we use different material for manufacture die casting molds. Mold for making copper ingot has good ability in heating-proof.Continuous casting ingot machine has stepless speed regulating motor, then we can adjust ingot manufacturing speed easily.

  • How do you make an ingot cast
    How do you make an ingot cast

    Ingot cast is a casting method used to create metal ingots or ingots. The method involves pouring molten metal into a pre-prepared casting form, allowing the metal to cool and solidify to form a solid cast block, known as an ingot or ingot. This casting method is commonly used in the metalworking and metallurgical industries to produce standardized metal billets for subsequent processing and manufacturing

    What is the process of ingot casting

    What is the process of ingot casting? Ingot casting is a common metalworking method used to create primary forms of metallic materials. Ingots are massive metal billets, usually rectangular or cylindrical, that are subsequently hot-worked or processed into the desired end product.
