Slab coal consumption monitoring method of hot continuous rolling production line

Abstract

The invention discloses a slab coal consumption monitoring method of a hot continuous rolling production line. The method relates to each section in a heating furnace, instantaneous flow meters of the various sections and an instantaneous flow totalizing meter, and comprises the following steps: A, periodically acquiring numerical values of the instantaneous flow meters of the various sections and the instantaneous flow totalizing meter from the heating furnace in real time; B, calculating proportion of the instantaneous flows of the various sections according to the readings of the instantaneous flow meters, and assigning a difference value of the current reading and the reading of the instantaneous flow totalizing meter of a previous period to obtain a gas flux consumption value of each section; C, assigning a gas flow consumption value of each section of the current period according to the percentage which is obtained by dividing the unit weight of each slab of each section of the current period by the weight sum of the slab of the current slab, namely the gas consumption of each slab in the current period; D, considering the sum of gas consumption of each period after discharge of the slab as the total coal consumption of each slab. According to the method, the problem that the production cost accounting is affected due to inaccurate monitoring of the coal consumption of the existing hot continuous rolling production line can be solved.

Description

technical field [0001] The invention relates to the technical field of iron and steel production, in particular to a method for monitoring slab coal consumption in a hot continuous rolling production line. Background technique [0002] At present, the informatization and automation level of production management of hot rolling production line is developing rapidly. With the increasingly severe steel market, the steel industry has entered the era of meager profits. How to reduce production costs and realize profits is the direction that every hot rolling mill is working hard to tackle. Among them, the cost of coal consumption is one of the main cost consumptions of the hot rolling production line. Accurately calculating the coal consumption of each slab and performing single-product coal consumption cost accounting for some specifications with high coal consumption will play a great role in reducing coal consumption. . At present, the domestic steel mills’ statistical method...
