Midi beneficiation plant more than 10 years of production index has been relatively stable, the Panzhihua steel company to meet production requirements. The main problems still exist are:
1) Although the crushing particle size is less than 25mm, the grain size is more than 95%, but for a grinding process, it is still slightly thicker;
2) The processing capacity of the ¢3600×4000 grid type ball mill is about 10t/(unit.h) lower than the design index. The reason is as follows: First, the grade of raw ore is reduced, resulting in a decrease in the treatment volume. It is known from the test data that the lower the ore grade, the finer the grain size of the inlay, the harder it is, the harder it is to grind, see the table below, and the second is grinding. The classification efficiency is low and there is an "over-grinding" phenomenon.
The process indicators of the plant's iron selection are shown in the following table:
The unit consumption index of crushing and sieving and iron selection is shown in the following table:
The main equipment for crushing and sieving and iron selection, see the following table:
Nickel Based Laser Cladding Powder
Ni base alloy powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has good wettability, corrosion resistance and high temperature self-lubricating effect, and is used in components with heat resistance, corrosion resistance and thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser cladding, the No means hardness of powder. Inconel 625 and 718 has good corrosion property under higher temperature, also widely used for laser cladding process.
Cobalt based Laser Cladding Powder
Cobalt-based alloy powder is the cemented carbide resistant to various types of wear and corrosion as well as high temperature oxidation. That is, the so-called cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, Alloying elements such as lanthanum, and occasionally a class of alloys containing iron.
Co-based self-fluxing alloys have good high temperature performance and wear resistance and corrosion resistance, and are used in petrochemical power, metallurgy and other industrial fields where they are wear-resistant, corrosion-resistant and high-temperature resistant.
Iron based Laser Cladding Powder
The work pieces required for laser cladding and manufacturing in the actual industry are mainly carbon steel and cast steel. The Fe-based alloy is close to the base material in composition and has good wettability. The advantage of Fe base powder is lower cost and good wear resistant of cladding layer. As a result, it`s the most widely used for laser cladding process. It is suitable for parts that require local wear resistance and are easily deformed.
WC blended Laser Cladding Powder
Tungsten carbide blended with Ni alloy powder is the best choice for wear resistant work piece. This unique process can bring excellent wear, corrosion and high temperature resistant. Our blend powder can achieve different portion of WC from 35% to 60% without crack under suitable cladding parameter.
