Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Several factors of hot pressure graphite mold damage

1. Broken: Graphite mold directly contacts the matrix powder containing diamond. The contact surface is in a high pressure state. The hardness of diamond and graphite mold is too poor. The surface of the mold that is in contact with diamond tool head will produce concave pits.Second, the type of damage: During the sintering process, the matrix powder infiltrates into the oxidation gap of the graphite mold under the melting state, resulting in the adhesion between the tool head and the mold, making it difficult for molding. The repeated attack of the mold can remove the mold, which causes the lack of edges and metal pit in the mold.Third, the wear size of graphite molds is very poor: some substrate powder will be squeezed out of the mold surface in the melting state to attach to the graphite material. Before using the mold next time, metal residues must be removed manually, which causes the shape and size of the mold to exceed the tolerance.Fourth, surface oxidation and cracking: Becau

Mold graphite

The casting industry in the mechanical industry uses graphite materials as molds such as pressure casting, centrifugal casting, and hot squeeze of super hard alloy. It can use graphite molds as large as train wheels and small as small as precision parts. Graphite molds can be repeatedly used for multiple times. After the molding, the casting has a high degree of smoothness, and some can be used without further processing. The graphite material used for casting molds should be graphite with a dense texture, low thermal expansion coefficient, and good antioxidant performance. Graphite, which is used for casting with large casting size, can be composed of thicker particle size. It is used for casting small precision parts The graphite must be graphite with fine particles. The number of graphite used to make molds in China is large. In 2005, it was continuously cast about 1500T with graphite and sintering molds were estimated to cost 4000T.
