Carbide Milling Cutters SPIRON17-150-L/R11

The factors that affect the relative magnetic saturation value of cemented carbide alloys mainly include the following six factors:
1. The WC total carbon in the cemented carbide exceeds the standard.
2. The oxygen content of the mixture (including briquette) exceeds the standard.
3. Changes in carbon content in hydrogen dewaxing and pre-burning.
4. Changes in carbon content in vacuum dewaxing and pre-burning.
5. Changes in carbon content during hydrogen sintering.
6. The change of carbon content in the vacuum sintering process of cemented carbide.

According to the data provided by Cemented Carbide Branch of China Tungsten Industry Association, in 2011, there were more than 300 cemented carbide production enterprises, more than 30 professional scientific research institutes, and more than 25,000 employees in the whole industry. As of 2011, it has a tungsten concentrate production capacity of 100,000 t/a, a tungsten acid and tungsten salt production capacity of 180,000 t/a, a tungsten carbide production capacity of 62,000 t/a, and a cemented carbide production capacity of 38,000 t/a. , and the supporting supply capacity of Co, Ni, Ta, Nb, Ti.

In 2011, China's cemented carbide output was 23,500 tons, the sales revenue of cemented carbide industry was 20.9 billion yuan, the cemented carbide export was nearly 5,000 tons, and the export earnings exceeded 360 million US dollars. The output of cemented carbide deep-processing products reached 6,600 tons, accounting for the total alloy 1/3 of the output. The variety of cemented carbide products produced is basically complete, with more than 40,000 specifications and models, and the output and variety can basically meet the needs of various economic fields in China.
