Abstract

The present invention relates to the calcium carbide field, in particular to a method for calcium carbide quality control. First, calculate the theoretical content and saturation coefficient of CaO and C in the mixed material: set the CaO content of lime in the mixed material as a, and the C content of the carbon material as b , the theoretical content of CaO is A, and the theoretical content of C is B. Use the rate value method to control the material ratio, set K as the saturation coefficient, and determine the K value; secondly, determine the detection value A of the CaO content in the actual mixed material Ⅰ and saturation coefficient K Ⅰ , and sampling, analysis, record the detection value of CaO A Ⅰ and the detection value of C B Ⅰ , and calculate K Ⅰ value, and then count the day A Ⅰ or K Ⅰ pass rate; finally, set A Ⅱ or K Ⅱ is the control index value, A Ⅱ =A±1% or K Ⅱ =K±0.02, when A Ⅰ in A Ⅱ range or K Ⅰ in K Ⅱ qualified within the range. By adopting the calcium carbide quality control method of the present invention, the problem in the prior art that the accuracy of furnace material proportioning is low during calcium carbide processing and resulting in low calcium carbide quality is effectively solved.

Description

technical field [0001] The invention relates to the field of calcium carbide, in particular to a method for controlling the quality of calcium carbide. 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. Carbon material (C) and lime (CaO) 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 various parts of my...
