Embodiment Construction

[0017] Below in conjunction with specific embodiment, further illustrate the present invention.

[0018] In order to improve the start-up control process of the existing COREX slag grinding production control system, the control system is divided into vertical mill main engine G and auxiliary lubrication subsystem A, air compressor subsystem B, finished product conveying subsystem C, dust collection Subsystem D, coarse material circulation subsystem E and hot blast furnace subsystem F, as well as feeding subsystem H and water supply subsystem I connected to the vertical mill, the lubrication subsystem includes the mill reducer lubrication unit, grinding roller spindle Lubrication unit, powder separator lubrication unit, powder separator reducer lubrication unit, also includes the previous single-row hydraulic unit and the previous sealed fan as auxiliary equipment.

[0019] The specific steps to start the control process are:

[0020] (1) Check and confirm the status of each ...

Abstract

The invention relates to a start control process for a COREX slag grinding production control system. The control system comprises a vertical grinding host machine (G), and a lubricating sub-system (A), an air compressor sub-system (B), a finished product conveying sub-system (C), a dust collection sub-system (D), a crude material circulation sub-system (E) and a hot air furnace sub-system (F) serving as assistance, as well as a feeding sub-system (H) and a water supply sub-system (I). The start control process comprises the following concrete steps: (1) checking and confirming the state of each assisted device; (2) implementing start on each sub-system based on the sequence of A-I; and (3) adjusting fineness, regular checking, and adjusting parameters of related systems. The process recombines the sub-systems of the conventional process, strictly starts according to a certain sequence with rigorous procedure, and is advantageous to production operation and production stability; a related hydraulic unit is firstly started so as to contribute to normal operation of subsequent equipment and improve the service life of the equipment.

Description

technical field [0001] The invention relates to a start-up control process of a grinding production process, in particular to a start-up control process for a COREX slag grinding production control system. Background technique [0002] With the completion and use of the world's first vertical mill for grinding and reusing COREX slag independently developed by Baosteel, and its successful commissioning and successive use of products, the production control system and production of COREX slag grinding The study of technology is further in-depth. [0003] At the end of 2008, our company disclosed a slag grinding production control system in the invention application with application number 200810044047.2, which disclosed the process principle of the COREX slag grinding production system, the system composition and the COREX slag powder production process. COREX mineral powder production system is attached figure 1 As shown, the mineral powder production line is divided into n...
