Abstract

The invention relates to formed coke adopting semi-coke powder as a main raw material, a preparation method and application. The formed coke is prepared from the following raw materials in parts by weight: 100 parts of the semi-coke powder, 3 to 5 parts of high temperature binder, 0.2 to 0.5 part of penetrating agent and 10 to 15 parts of water, wherein the high temperature binder is prepared from an organic binder, an inorganic binder, a wetting agent and a cross-linking agent. The formed coke produced by adopting the raw materials has the three-high one-low advantages of high forming rate, high mechanical strength, high temperature resistance and low cost; the optimum usage of the semi-coke powder is realized, and the resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of blue coke powder molding, in particular to a form coke with blue coke powder as the main raw material, and also relates to a preparation method and application of the form coke. Background technique [0002] Semi-coke, also known as semi-coke, is a new type of carbon material obtained by low-temperature dry distillation of high-quality Jurassic clean coal blocks abundant in Shenfu, Yulin, and Dongsheng coal fields. Semi-coke has the advantages of "three highs and four lows" such as high fixed carbon, high specific resistivity, high chemical activity, low ash content, low sulfur, low phosphorus, and low moisture. It gradually replaces metallurgical coke and is widely used in the production of metal silicon and ferroalloys , ferrosilicon, silicomanganese, fertilizer, calcium carbide and other high energy-consuming products. [0003] China is a big country in the production of semi-coke, and it is also a bi...
