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. Table 4 is the specifications and technical perf

Classification of graphite blocks

Classification of graphite blocks of graphite block classification of graphite blocksThe crushing of graphite blocks can be divided into three items, do you know?Pre -fragmentation (or crushing): This also refers to the crushing of block -shaped graphite block raw materials after entering the factory. Generally, it refers to crushing the block of the block of 200mm to 50 ~ 70mm.Middle crushing: This also refers to the granular block of graphite blocks that is further broken until the granularity necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Essence (or grinding): It is the following powders to grind some graphite raw materials to 0.15mm or 0.075mm particle size. Every time it goes through, the granularity of the raw materials has become smaller. The larger diameter of the large raw material before crushing is the ratio of the diameter of the larger block of the raw material after crushing, which is called a crushi

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.

How to Use Expanded Graphite

1. Protective purposesExpanded graphite can be used as a protective material to protect metals and other easily damaged objects, such as circuit boards and steel. Due to the fact that expanded graphite can expand up to 10 times, it can effectively block flames and prevent these objects from being burned by flames.2. Insulation purposeExpanded graphite can also be used as insulation material because it has good thermal resistance performance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing heat loss, and thus providing insulation.3. Filtering purposeExpanded graphite can also be used as a filter material because it has adsorption properties and can be used to adsorb toxic substances, such as pollutants in water treatment, effectively removing pollutants from water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement purposeExpanded graphite can also b

The purpose of graphite machining

Various carbon graphite products, although they have a certain shape and size after forming, undergo expansion and contraction, deformation and bending, collision or corner dropping during the process of roasting, impregnation, and graphitization treatment from the pressed blank to the graphitized blank. The surface adheres to some fillers and insulation materials, resulting in roughness and unevenness. Their shape and size change to a certain extent, and they cannot achieve the shape of the product during use, Due to strict requirements for size and surface roughness, it cannot be used without mechanical processing. In addition, some products have complex structures and shapes that cannot be directly produced by forming methods, such as metal continuous casting and rolling graphite crystallizers, electric spark machining graphite molds, carbide sintering graphite boats, discs, and other special graphite products. Some products require interconnection when used, such as the connection

Advantages and disadvantages of graphite purification methods

Flotation method is one of the conventional mineral purification methods that consumes the least energy and reagents, and has the lowest cost. This is the biggest advantage of flotation method for purifying graphite. However, using flotation to purify graphite can only achieve a limited increase in its grade. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomer, but also is not conducive to protecting the large scale of graphite. Therefore, using flotation to further improve graphite grade is neither economical nor scientific. To obtain high carbon graphite with a carbon content of over 99%, chemical methods must be used to purify the graphite.(1) Alkali acid purification method. The carbon content of graphite purified by alkaline acid method can reach over 99%, which has the characteristics of low one-time investment, high product grade, and strong process adaptability. Moreover, it also has the advantages of conventional equipment and stro
