How to improve anti-oxidation property of graphite materials? Water-soluble impregnant
How to improve anti-oxidation property of graphite materials? Water-soluble impregnantGraphite materials have very specific properties such as good electrical and thermal conductivity, self-lubricating, low hardness, low friction, high temperature resistance, etc., and have a wide range of applications in metallurgy, electrical, electronic, mechanical, chemical, and nuclear ind... ...
Graphite electrode thread production process
Graphite electrode thread production processAccording to the design idea, the standard gauge block of the inner taper thread should be processed first, then the inner taper thread should be machined, and finally the corresponding outer taper thread should be machined according to the size of the inner taper thread to form a complete gauge system. The following describes the det... ...
Graphite electrode thread measuring principle & design ideas
Graphite electrode thread measuring principle & design ideas In recent years, the use of thread gauges has gradually become popular in the machining of graphite electrodes. However, because most of the existing thread gauges are imported products and are expensive, most small and medium-sized carbon companies still use the original limit gauges as the main control method of th... ...
Nipple pins for UHP graphite electrodes discussion
Nipple pins for UHP graphite electrodes discussionIn order to adjust the resistivity of the nipple pin, a mixture of coal-based needle coke and graphite powder are used. Due to the different surface properties of coal-based needle coke and graphite powder, the adsorption of asphalt is different, resulting in differences in the flow and expansion properties of the nipple pin at ... ...
Testing method graphite electrode chaser
Testing method graphite electrode chaser1 Measuring method of tooth profile half-angle(1) Adjust the angle of the rudder plate of the Universal Tool-Measuring Microscope eyepiece to 0°.(2) The operation of the Universal Tool-Measuring Microscope adopts the method of gradual approximation so that the two solid lines with an included angle of 60° of the double cross auxiliary lin... ...
Detection methods of graphite electrode chaser
Detection methods of graphite electrode chaser 1 Tooth top/tooth bottom straightness errorThe straightness error of the tooth top/tooth bottom is the connection line of the corresponding points of each tooth top and each tooth bottom of the chaser. Its direction has nothing to do with the taper angle of the thread. During the detection, the chaser is placed horizontally, and th... ...
Nipple pins for UHP graphite electrodes
1 Preparation processThe preparation process is shown in Figure 3.(1) GrindingGraphite, needle coke, and hard pitch are ground separately, and the purity is controlled above 70%.(2) MixingWeigh the pitch, graphite powder, and needle coke powder into the mixer according to the formula ratio. After mixing for 5 minutes, weigh the expanding agent according to the formula and pour ... ...
The study of nipple pins for UHP graphite electrode
Since the invention of EAF steel-making method in 1899, EAF steel-making has become the main process for smelting special steel after more than 100 years of development. Graphite electrode is an irreplaceable high-temperature conductive material for electric arc furnace steelmaking because of its excellent conductivity and heat conduction properties, good toughness, strong curr... ...
Graphite electrode processing technology
The straightness error of the tooth top/tooth bottom is the connection line of the corresponding points of each tooth top and each tooth bottom of the chaser. Its direction has nothing to do with the taper angle of the thread. During the detection, the chaser is placed horizontally, and the coordinates of each point are measured and recorded. The method evaluates the magnitude ... ...
