The use of graphite molds is diverse

1. Graphite molds can be used as conductive materials in industry. In this regard, when using electric arc furnaces or submerged arc furnaces to smelt various alloys, strong current will be introduced into the melting zone of the electric furnace through the electrodes of the graphite mold to generate an arc. At the same time, electrical energy will be converted into heat energy to increase the temperature, which can achieve the production conditions for smelting and reaction.2. Graphite molds can be used as corrosion-resistant structural materials in industry. Due to the excellent corrosion resistance of the raw materials in graphite molds, they are often used in stainless steel and other products.3. Graphite molds can be used as compression and casting molds in industry. Due to its relatively small coefficient of thermal expansion and good heat and cold resistance, it can be used as a mold for various glassware and can also save a large amount of metal.4. Graphite molds can be used

What are the characteristics of the thermal stability of the film -shaped graphite

Sheet -shaped graphite is a natural ore, with a thin piece or scale, and the aggregate is in the form of soil. It is a hidden crystal. Film graphite has many high -quality physical and chemical characteristics, including good thermal stability. Compared with other products, the thermal stability of film -like graphite has great advantages.Film graphite is one of the most high -temperature -resistant materials at present. Generally, the strength of the material is gradually decreased at high temperature. However, when heating to 2,000 degrees Celsius, the strength of the sheet -shaped graphite is twice the temperature at room temperature.Sheet -shaped graphite has excellent heat shock resistance. When the temperature suddenly changes, the thermal expansion coefficient is small, so it has good thermal stability. When the temperature changes rapidly, cracks will not occur.Sheet -shaped graphite is a material with excellent thermal shock. For graphite electrodes used in electric furnace s

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.

Which raw materials are selected for the production of graphite electrodes

(1) Raw materials for the production of artificial graphite electrodes. All low ash raw materials such as petroleum coke and asphalt coke can be used to produce high-quality graphite electrodes. Adding asphalt coke is to improve the strength of the product. The production of ordinary power graphite electrodes can use ordinary quality petroleum coke as raw material; Produce high-power graphite electrodes using high-quality petroleum coke and some needle coke; To produce ultra-high power graphite electrodes, high-quality needle coke must be used as the raw material. To produce high-purity graphite electrodes, petroleum coke with very low ash content is required.

The difference between scales graphite and expansion graphite

Scales graphite is a kind of natural graphite. After the mines, it is pure. The general shape is fish -like, so it is called scale graphite.
