Embodiment

[0113] A modeling method for the weighing process of the alloy feeding system, which analyzes the relationship between the on-site process structure and historical production data and the weighing accuracy of the alloy, and the strong vibration feeding speed v F, strong vibration time t F , strong vibration time t S , transition velocity v T , transition time t T , Weak vibration feeding speed v L , weak vibration time t L , the amount of material Δm at stop vibration is used as the control parameter, and a five-stage analysis method is proposed to model the alloy feeding process mathematically, and expert rules are introduced to optimize the model. Specific steps are as follows:

[0114] (1) collect data samples in the on-site computer server;

[0115] Analyze the historical production data of the alloy feeding process, add the tag position of the required data in the on-site computer server, take 0.5s as the sampling time, and analyze the feeding start time, strong vib...

Abstract

The invention discloses an alloy feeding method and device and belongs to the technical field of furnace burden control during metallurgy. The alloy feeding method and device is achieved on the basis of a vibration feeding machine. The method divides the alloy feeding process into five linear processes which include a strong vibration stage A, a strong vibration material sliding stage B, a transition stage C, a weak vibration stage D and a vibration stopping material sliding stage E, and alloy feeding is performed through a mathematic model m=vFtF+vFtS+vTtT+vLtL+delta m. The device can automatically control the alloy feeding process on the basis of the method. The alloy feeding method and device has the advantages that randomness and uncertainty generated by manual feeding can be eliminated effectively, and production efficiency and machining precision are well considered.

Description

technical field [0001] The invention relates to the technical field of charge control in metallurgical processes, in particular to an alloy feeding method and an alloy feeding device. Background technique [0002] In recent years, due to overcapacity and high raw material prices, most steel industries are facing survival challenges. Under the current situation, traditional production is of little help to improve the company's benefits, and there is an urgent need to develop new steel industries. The development of new steel types has put forward new requirements for the quality of slabs, and the alloy content in molten steel is one of the key factors affecting the quality of slabs. . Too high or too low alloy content will seriously affect the quality of iron and steel smelting, and too high alloy content will cause waste of resources and increase production costs. In order to realize the alloy feeding in the metallurgical process, [0003] The authorized announcement numb...
