Win the five major battles, see my "master move"②22.25

"Five major battles" in full swing thousands of acres of sea passionate in this war, the majority of cadres and workers to a place to think, to a place to make the initiative to integrate, actively participate in their own work, active work from their own, from now on, from daily start have shown their own "magic" to contribute to the final victory

Trick: Crane operation "one meter electricity" steel mill running area is responsible for the operation and maintenance management of 38 cars, most of the cars have large load weight tonnage, high motor power and frequent operation, is the steel mill electricity "big". In order to ensure the safe and stable operation of the car and effectively reduce power consumption, we use lean management thinking, tools and methods to implement positioning management for each car, and take positioning marks for the big car and the main and auxiliary hooks to ensure that the staff operate the car in one step, do not do useless work, save "one meter of electricity", such as when the heavy load of the car with a load of 380 tons. If the main hook exceeds the lifting height of 1 meter, and then resume operation to the required height, the power consumption is about 10 degrees; If the truck runs 1 meter more, and then returns to the required position, it needs about 2 degrees more power, increasing the production cost. By implementing the operation of driving positioning, we not only improve the working efficiency, but also effectively reduce the production cost.
Trick: Ingenuity, transmission of "a trace" arc technology continuous casting machine off-line preparation accuracy, the sector segment online life and billet quality is crucial, and sector segment arc is an important part of it. The arc technique is like the traditional Chinese medicine "look, smell, ask and cut", with different angles and different strengths to obtain completely different data. To this end, we teach arc technology, everyone is familiar with arc strength, arc accuracy is not only stable within 10 wires, but also let the human deviation control within 3 wires, to ensure arc stability, reduce the casting defects caused by arc error, and reduce the downtime caused by poor arc accuracy, contributing to the company to enhance market competitiveness.
Hot rolled strip thin gauge rolling stability "One two three four five" operation method for hot rolled strip thin gauge high strength steel production stability is poor (including sticking steel, tail, roll marks, wave shape defects, uneven thickness of the whole roll and other key parameters deviate from the target value), site tracking summary adjustment operation method, a "preparation" : prepare the roll; Two "guarantees" : production plan guarantee, billet size guarantee; Three "adjustments" : adjust the furnace loading mode, adjust the heating mode, adjust the process mode; Four "controls" : control rolling sickle bend, control the middle pass, control roll gap adjustment, control rolling rhythm; Five "optimization" : optimization of mill cooling water, optimization of finishing load distribution, optimization of strip section control, optimization of plate shape model, optimization of personnel allocation. The operation method is a series of operation methods for the production of thin strip steel, and has strong operability, which can effectively improve the rolling stability and efficiency, ensure the stable production of strip steel, improve the surface quality of products, and rapidly improve the production efficiency.
Unique Move: Based on various problems in the actual production of high value-added strip steel such as bridge steel, pipeline steel, etc., the control of side guide plate, inclined slide guide roller, coiling roller and unloading trolley of the coiler is researched and innovated. By using side guide plate double guidance, double clamping and automatic and manual switching control of pressure position, The whole process pressure coiling control of high-strength and high-strength strip coiling roll and chute guide roll, and the speed control of unloading trolley stage have achieved remarkable results, and the high quality production coiling of thick and high-strength strip steel has been realized.
