An Optimum Design Method for the Length of Blast Furnace Main Belt

Abstract

The invention belongs to the technical field of industrial production, in particular to an optimal design method for the length of the main belt of a blast furnace. Aiming at the problems such as the decrease of the feeding speed caused by the insufficient length of the main belt and the waste of equipment capacity caused by the excessive length of the main belt, the following scheme is proposed , including the combination of the blast furnace top automatic feeding model of the feeding system using the main belt, the feeding equipment and the feeding sequence, setting the starting time of the feeding signal, and converting the length and speed of the main belt into time T L , according to the maximum batch weight and equipment design capacity in the design requirements, t can be obtained o and t zo , and then the running time t of the material itself o , Material from the upper tank to the lower tank t zo , and T L The feeding time t of the material can be obtained by adding up, and the feeding speed K can be calculated from this. The invention enables engineers and technicians to calculate the optimal length of the main belt, and can avoid the problems of the decrease of the feeding speed caused by the insufficient length of the main belt and the waste of equipment capacity caused by the excessive length of the main belt.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to a method for optimizing the length of a main belt of a blast furnace. Background technique [0002] The feeding system is the main component of the blast furnace process, which includes two systems: under-trough feeding and furnace roof distribution; in recent years, with the continuous increase of the effective furnace capacity of newly built blast furnaces, belt feeding and bellless bells have been widely used The craft form of the stove top. [0003] The feeding speed is the most important indicator of the feeding system, which directly affects the output and energy efficiency of the blast furnace. Practice has proved that the feeding speed is affected by factors. [0004] At present, the main belt feeding has become the trend of new large and medium-sized blast furnaces, and the length of the main belt is an important design parameter, which needs to be selecte...
