Abstract

The present invention provides a normal pressure method coking coal and ore powder molding binder and a molding method, wherein the binder comprises 62% of clear water, 22% of weathered coal humic acid, 6% of caustic soda, 5% of a high temperature penetrant, and 5% of a high temperature waterproof agent. The production method comprises: 1, placing clear water into a reaction kettle to heat to a temperature of 60 DEG C; 2, placing weathered coal humic acid and caustic soda into the reaction kettle, stirring, and heating to a temperature of 85 DEG C; 3, adding a high temperature penetrant and a high temperature waterproof agent to the material obtained in the step 2, carrying out thermal insulation for 20 min, cooling to 50-60 DEG C, and taking the solution so as to obtain the finished product; and 4, placing the mixed material into a storage tank, and maintaining the 40-50 DEG C state for use. The molding method comprises: 1, processing coking coal powder into 50-100 mesh powder, and processing ore powder into 60-120 mesh powder; 2, taking a binder according to the coking coal powder content of 18-20% and the ore powder content of 15-18%; 3, conveying into a disc granulator to carry out mixing granulation; and 4, carrying out air-drying or drying to obtain the molded material. The obtained molded material can not burst at a high temperature of more than 1350-1600 DEG C, the cold material can not be subjected to moisture regain, and the material can be used for yellow phosphorus, metal smelting, calcium carbide production and other industries.

Description

technical field [0001] The invention relates to a binder for forming waste coke, coal and ore powder, in particular to a coking coal and ore powder forming binder and a forming method under normal pressure. Background technique [0002] In the electric furnace smelting production, the charge entering the electric furnace must be 0.5-5cm particles. In order to meet the needs of this production process, the coke and ore should be crushed before the charge enters the electric furnace. During the crushing process and storage and transportation, It is inevitable that some fine powders with a diameter of less than 0.5cm will be produced. Since these fine powders cannot enter the electric furnace, they are all treated as waste materials. This traditional treatment method has not only caused economic losses, but also caused waste of natural resources. Contents of the invention [0003] The purpose of the present invention is to effectively solve the problem of loss and waste caus...
