Improved effect of the shutdown of Acheson graphitization furnace
1 Improved effect1.1 Improvement of the unqualified rate of graphitizationAfter the graphitization shutdown judgment method is improved, mainly for the electro-oxidation unqualified rate has been greatly improved get the super quality graphite eletrode products. Take SHP electrode as an example, Table 4 is the actual production data.It can be seen from Table 4 that by improvin... ...
Judgement for the shutdown of Acheson graphitization furnace
At the present situation of graphite electrode production in the graphitization process, power distribution system was used to control the rising rate of furnace core temperature of Acheson graphite furnace, and cumulative amount of power to achieve the final plan power outage was the basis of the shutdown of Acheson graphite furnace, which has many defects. The ideal shutdown ... ...
Three-phase multi-electrode layout submerged arc furnace power transmission and smelting
1 The layout of three-phase multiple extruded graphite electrodes in submerged arc furnaceThe smelting steps of CHP electrode in submerged arc furnace:1) Each phase of the three-phase terminal on the secondary side of the transformer is divided into at least two parallel electrode terminals, and each electrode terminal is connected with a column electrode respectively; Or, the ... ...

Discussion of mixing of different kinds of coal pitches on coking quality
Experimental results and discussion1 Analysis results of thermal reactivity of pitchFrom the experimental results Table 4, it can be seen that the low-quinoline refined pitch treated by the scheme 1, scheme 2, and scheme 3 has relatively good coke quality, while scheme 4 and scheme 5 have unsatisfactory coke quality to view the high quality graphite electrode information.The hi... ...
Effects of mixing of different kinds of coal pitches on coking quality
Effects of mixing of different kinds of coal pitches on coking qualitySeveral different pitches mixed with aromatic oil were carbonized in order to investigate the effects of mixing on the thermal reactivity and the coking quality. The carbonization yield, temperature sudden change and the duration were tested to view graphite products for reference. The microstructures of the ... ...
Development of new type baking furnace horizontal wall bricks
Development of new type baking furnace horizontal wall bricksThe top brick of the traditional fired horizontal wall is built with 400 mm thick prefabricated blocks. There is no smoke exhaust hole on the top of the horizontal wall. The smoke exhaust hole is on the fire channel wall. The prefabricated block on the top of the fire channel wall has 4 holes. Get the baking furnace u... ...
