China UHP Graphite Electrode manufacturers

China UHP Graphite Electrode manufacturers Product Description Process flow of graphite electrode production (1) the calcination Petroleum coke or asphalt coke needs to be calcined, calcination temperature should reach 1300鈩? in order to fully remove volatile in the raw material, improve the true density and electrical conductivity of coke. (2) Crushing, screening and ingredients The calcined raw material is broken and sieved into aggregate particles of specified size, and a part of the raw material is ground into fine powder. After weighing according to the formula, the mixture of various particles is assembled. (3) the kneading In the state of heating, the quantitative mixture of various particles and quantitative binder are mixed and kneaded into plastic paste. (4) shape Under the action of external pressure (molding or extrusion molding) or vibration (vibration molding), the paste is pressed into a certain shape and a higher density of the blank. (5) roasting The billet was placed in a specially designed high temperature furnace, and the billet was covered with filling material (coke powder or river sand), and the temperature was gradually raised to about 900 ~ 1100鈩?to make the binder carbonized, so as to obtain the roasted product. (6) soaking In order to improve the bulk density and mechanical strength of the product, the roasted product is loaded into the autoclast, and the liquid impregnating agent is pressed into the pores of the roasted product. After impregnation, it should be roasted again. In order to obtain the joint blank with high density and high strength, the impregnation needs to be repeated 2 ~ 3 times. (7) graduation鈥?br> The CALcINATION WAS PUT INTO THE GRAPHITIZATION FURNACE (covered with insulation material), and the calCination was transformed into the graphite crystal structure by direct electrifying heating method, so as to obtain the physical and chemical properties needed for the artificial graphite electrode. (8) Mechanical processing According to the requirements of use, the graphite blank is processed for surface turning, end face processing and screw hole processing for connecting, and then processed for connecting joints. (9) The finished product shall be packaged after passing the inspection. 聽聽 Product Specification 聽聽 Applicable Nipple information 聽聽 Package Plywood packing, seaworthy packing 聽聽聽 Transport & Export 聽聽聽聽 Service Calgon Carbon has an experienced and highly skilled service team, which always insisting on the service concept of "honest service and perfection", continuously deepening marketing services, extending service contents for the whole process of, pre-sales, in-sales, and after-sales throughout the entire marketing process, which providing the customer with technical positioning, guidance, and full tracking service of steel making testing.
