Abstract

The invention relates to an intelligent weighing method for a travelling crane. The method mainly aims at solving the technical problems in an existing steelmaking production process that the fluctuation of a measured value of the travelling crane is great and the weighing precision is low. According to the technical scheme, the intelligent weighing method provided by the invention comprises the following steps: (1) acquiring travelling crane data and automatically acquiring working parameters of the working travelling crane through a travelling crane dispatching computer system; (2) judging a hoisting state of the travelling crane and judging a travelling crane working procedure position and a hoisting working state through the travelling crane dispatching computer system according to a travelling crane operating zone and positions from main and secondary hooks of the travelling crane to a travelling crane girder; (3) weighing a travelling crane hoisted object, raising the travelling crane hoisted object for a certain height and keeping stable and weighing the hoisted object in real time through a weighing apparatus on a transverse beam of the main hook of the travelling crane; and (4) judging weighing original data of the travelling crane. According to the intelligent weighing method for the travelling crane, a computer system and the travelling crane dispatching computer system are controlled by utilizing an existing production process of enterprises and automatic weighing of the travelling crane hoisted object is realized; and the intelligent weighing method is high in weighing precision and low in cost, the smelting precision of a converter is effectively ensured and steelmaking-continuous casting production is stably and smoothly carried out.

Description

technical field [0001] The invention relates to a driving weighing method, in particular to a driving intelligent weighing method, in particular to a method for automatically measuring the weight of hoisted objects by driving in the steelmaking production process, which belongs to iron and steel metallurgical measurement. Background technique [0002] The type and amount of main and auxiliary raw materials added are very important in the steelmaking process. According to the difference in smelting steel types and the amount of main raw materials added, the requirements for adding auxiliary raw materials are also different, which directly affects the final smelting molten steel composition, molten steel temperature and manufacturing cost. Restricted by the requirements of the production rhythm, the pouring of molten iron, measurement of molten iron, hoisting of molten iron and pretreatment of molten iron are completed within a limited time, and after the smelting is completed...
