1. The product parameters of graphite electrodes include size parameters, density parameters, conductivity parameters, tensile strength parameters, and corrosion resistance parameters. These parameters directly affect the effectiveness and lifespan of graphite electrodes. Therefore, when selecting and using electrodes, attention should be paid to the specific situation of these parameters.

2. Product parameters of magnesium spray repair material: The main physical and chemical properties are as follows:

Chemical composition: MgO greater than or equal 80%, CaO less than or equal 3.0%, SiO2 less than or equal 5.0%

Volume density: 110 ℃, dried for 24 hours, 2.4g/cm3

Pressure resistance strength: 110 ℃, after 24 hours, greater than or equal 10Mpa

1300 ℃, after 8 hours of burning, greater than or equal2.5Mpa

Adhesion rate: greater than or equal 86% when initially sprayed into the hot state (about 1200 ℃), greater than or equal 95.5% in the cold state

Maximum temperature for use: 1750 ℃

Usage: When spraying, the spray gun head should be evenly moved to prevent excessive local accumulation and rapid evaporation of water, which may cause the spraying layer to burst and peel off. When the thickness of the spray coating is ≤ 100mm, the distance between the spray gun and the spraying surface should be 1.5 meters. When the thickness of the spray coating is 50mm, it can be put into use without special baking.

Storage time: can last for one year in a dry environment.
