Porous efficient carburant blended with nano-copper for reusing waste graphite electrode and preparation method of porous efficient carburant

Abstract

The invention relates to the field of carburant, in particular to porous efficient carburant blended with nano-copper for reusing a waste graphite electrode and a preparation method of the porous efficient carburant. The waste graphite electrode is used as a carbon material of the carburant. Water glass, ammonium bicarbonate, polyethylene glycol 400 and other materials are used for preparing a low-impurity composite binder. The materials baked at high temperature are of a tight porous structure. The added nano-copper has the effect of promoting graphitization. The recarburization effect of the materials is improved, and the mechanical property is improved. Silicon particles are pasted on the surfaces of the materials after silica gel sprayed on the surfaces of the blank materials is dried, so that molten liquid graphitization is further promoted, blank liquidity is improved, and rapid melting is achieved. The carburant prepared by the preparation method is high in carbon content, stable in morphological property, good in recarburization effect, high in cost performance and capable of effectively improving metal product quality.

Description

technical field [0001] The invention relates to the field of recarburizers, in particular to a porous and high-efficiency recarburizer mixed with nano-copper for reusing waste graphite electrodes and a preparation method thereof. Background technique [0002] During the smelting process, the carbon content in the material did not reach the expected standard due to improper ingredients, charging or excessive decarburization, which directly affected the performance of the product. Therefore, it is necessary to add a carburant during the production process. The recarburizer helps to reduce the cost of smelting production, improve the quality of smelted metals and castings, and improve the efficiency; commonly used recarburizers include artificial graphite, calcined petroleum coke, natural graphite, coke, anthracite and compounds composed of these materials However, these materials have defects such as high cost, high impurity content, poor melting effect, and low utilization ra...
