3, the concept of clean steel system engineering
The production of low-cost high-quality clean steel is by no means achieved by relying on a certain advanced equipment, an advanced process or an advanced technology, but must be the comprehensive embodiment of the entire process of steel production equipment, process, technology, management and operation, and is the system engineering of the whole process of production. It is necessary to think about the whole system from the four dimensions of vertical, horizontal, high and hour. How to continuously produce high-quality clean steel at low cost, this paper puts forward the concept of four-dimensional space thinking of low-cost high-quality clean steel
1) Vertical concept
Vertical concept, that is, to think from the whole system and the whole process. For the production of low-cost high-quality clean steel, we must carefully grasp every production link from iron making to steel rolling. The whole process of ironmaking, pretreatment, steelmaking, prerefining, off-furnace refining, in-package metallurgy, continuous casting, heating, continuous rolling (heat treatment), cold rolling and so on is controlled, ignoring any link will bring irreparable impact on the production of high-quality clean steel.
(2) The concept of “horizontal”
The horizontal concept is to think horizontally in every process link, that is, the impact of factors such as technology, equipment, raw materials, and personnel operations on the production of high-quality clean steel.
(3) The concept of height
The high concept is that the production of clean steel must be high quality, efficient, low consumption, environmental protection and low cost. At present, China’s steel productivity of more than 700 million tons, with the progress of society and the development of science and technology, those high energy consumption, high cost, high pollution, low quality of general products will certainly be eliminated. At present, there are many three high and one low steel enterprises to stop production or close down. Therefore, every process in the production of high-quality clean steel, every link must be a high starting point. It should be low cost, low energy consumption, high efficiency, environmentally friendly and conducive to sustainable development. Only in this way can we remain invincible in the face of the current brutal competition.
(4) The concept of time and space
The concept of time and space emphasizes continuity and reproducibility. The production of high-quality clean steel can not rely on engineering and technical personnel to follow every day, and can not rely on the selection of board by board after the product comes out. It should be that every furnace steel, every pouring time, and the products produced every month can be continuous, high-quality and clean. The time coordinates move, but the quality of the product remains the same. This requires a strict consistency of raw material stability, process stability, equipment stability, and worker operation stability.
