Example Embodiment

[0023] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0024] The present invention is aimed at the batching process flow of calcium carbide production ( figure 1 ) Calculate the material balance of the raw materials into the furnace, control the chemical composition of the raw materials into the furnace, so that the chemical composition of the raw materials into the furnace can not only meet the quality requirements of the production of calcium carbide, but also maintain the stability of the chemical composition of the raw materials into the furnace, so as to solve the proportion of calcium carbide production Problems with low accuracy and large fluctuations in composition. The specific process of this method is as follows:

[0025] 1. According to the relationship between the resistivity and air permeability of the mixture used in the production of calcium carbide and the particle size and raw material ratio, t...

Abstract

The invention relates to a controlling method for burdening of calcium carbide production, and belongs to the technical field of calcium carbide production. According to the influences of resistivity and permeability of material on smelting and with the maximum permeability and resistivity as optimization objectives, a mathematical model for optimization burdening is established; and through the calculation of optimization burdening, the optimum charging burden is obtained; chemical composition of the charging burden is controlled, so that the chemical composition of the charging burden can meet the quality requirements for calcium carbide production, and stability of chemical composition of the charging burden is maintained; and on the promise of ensuring quality of calcium carbide, optimization calculation of resistivity and permeability of the charging burden are conducted, and influence of other constraints are fully considered, so as to improve the furnace condition for calcium carbide production.

Description

technical field [0001] The invention relates to a method for controlling ingredients used in calcium carbide production, and belongs to the technical field of calcium carbide production. Background technique [0002] The main component of calcium carbide is CaC 2 , is an important raw material in the organic synthesis industry and plays an important role in the chemical industry. The smelting process of calcium carbide is a high-temperature physical and chemical change process. Coke and lime are put into the furnace in a certain proportion, and a chemical reaction occurs at high temperature to produce calcium carbide. In calcium carbide smelting, current is introduced into the furnace through three-phase electrodes to generate arc resistance heat, so that the raw materials undergo chemical reduction reaction at a certain temperature to form calcium carbide. [0003] Calcium carbide as the main chemical raw material has become one of the important pillar industries in vario...
