Carbide Inserts Mainly for the six main
For a professional manufacturer, each step of the carbide blade in the process is important because any of the processing steps may affect the quality of the blade. Here, our small series to come to tell us about the impact of carbide base blade relative magnetic saturation value of what factors? I hope to see the following knowledge, we can help.
From a professional point of view, there are many factors that affect the relative saturation of magnetic alloy blades, mainly for the six main aspects of these aspects of any one of the problems will affect the relative magnetic saturation of the blade, must pay great attention Caixing.
First, WC is the total carbon in the cement. Carbide blades in the WC total carbon standard is very strict, once the number of excessive, it will directly affect the relative magnetic saturation of the blade.
Second, the mixture or contain the oxygen content in the block over the standard, oxygen content will lead to excessive relative to the magnetic saturation value of the blade.
Third, hydrogen dewaxing, the amount of carbon in the pre-burning changes. In the process of production and processing of cemented carbide blades, especially in hydrogen dewaxing and calcination, the amount of carbon is always changing, and once the amount of carbon has exceeded the specified range, the relative magnetic saturation of the blade is affected Meet the relevant standard requirements.
Fourth, vacuum dewaxing, the amount of carbon in the pre-burning changes. In this session, dewaxing in the pre-burnt area must be sufficient to ensure relative magnetic saturation.
Fifth, the hydrogen sintering process changes in the amount of carbon. The change in the amount of carbon during sintering has a great relationship with the fixed carbon level of the mixture and the size of the fuel particle size.
Six is the carbide change during the vacuum sintering process.
From the above point of view, the impact of carbide relative to the magnetic saturation of the most important factor is the change in carbon content, and the impact of carbon changes in the link there are many, such as pre-burning, sintering and other links. To maintain a good relative magnetic saturation of the blade, it is necessary to strictly control the amount of carbon in a relatively safe range.
Each type of blade material has its specific processing range, can only be applied to a certain workpiece material and cutting speed range. Different cutting machine tungsten steel blade material and the same kind of blade processing different workpiece material blade life is often a big difference.
Slitting tungsten steel blade processing silicon content of high, medium and low aluminum alloy when its life is also very different. Therefore, the rational use of the blade is the key to successful cutting. Each blade material has its best processing object, that is, there is a reasonable match between the cutting blade and the processing object.
For the cutting machine tungsten steel blade blade toughness is better, safe and reliable, low linear speed, the price is suitable for processing more difficult materials. Tungsten steel blade manufacturers based on their own manufacturing process, may be used on the grade alloy powder made some special requirements.
Each type of tungsten steel blade material has its specific processing range, can only be applied to a certain workpiece material and cutting speed range. Different blade materials and the same kind of blade processing different parts of the workpiece when the blade life is often a big difference. Therefore, the rational use of tungsten steel blade is the key to successful cutting.
At the same time we have to consider the economy of tungsten steel blade, which is one of the important indicators of blade material selection, high-quality tungsten steel blade material Although the cost of a single piece of blade is high, but its long life, The cost is not necessarily high. So the choice of cutting machine tungsten steel blade material to consider its economic results.
