Modified asphalt and needle coke are uniformly mixed, and then 0%, 0.5%, 1.0%, 3.0% and 5.0% of Pr6O11 are added, and the additive proportion ... ...
Improvement measures of the service life of open ring type baking furnace
Improvement measures of the service life of open ring type baking furnace1 Masonry process control of baking furnaceThe control of the masonry process of the baking furnace is very important. If the control of the masonry process is not good, it is easy to cause the fire wall of the baking furnace to sink and deform. The traditional process uses refractory bricks and refractory... ...
Affecting reasons of the service life of open ring type baking furnace
Affecting reasons of the service life of open ring type baking furnaceThe open ring baking furnace in our country was developed on the basis of digesting the baking technology of Japan Light Metal Company introduced in the early 1980s. After more than 20 years of in-depth research and continuous innovation of baking furnaces by Chinese technicians, the service life of baking fu... ...
Two baking technologies of graphite electrodes discussion
Two baking technologies of graphite electrodes discussion1 Physical and chemical indicators of the productThe bulk density of the products baked in the ring furnace is very different at both ends, the maximum is 0.048 g/cm3, and the average is about 0.034 g/cm3, while the car bottom furnace is within 0.023 g/cm3. For the whole product, the product baked in the ring furnace has ... ...
Comparisons between two baking technologies of graphite electrodes
Comparisons between two baking technologies of graphite electrodesAs one of the important heat treatment processes in the production of graphite electrodes, it is a process in which binder bitumen is carbonized to form a whole by firmly coking aggregate and powder particles together. In this process, the raw product undergoes physical changes (the migration of asphalt, the volu... ...
Water-soluble impregnant improve anti-oxidation property of graphite materials
Water-soluble impregnant improve anti-oxidation property of graphite materials Antioxidant experimentThe oxidation resistance test was carried out in a box-type resistance furnace, and the oxidizing atmosphere was static air. The test temperature is 1,000 ℃. When the furnace temperature reaches the specified temperature, put the sample in the furnace and keep it constant for 2 ... ...
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 ... ...
