Chongqing Iron and Steel Steelmaking Plant No.1 Continuous Casting Operation Area： There are ingenious ways to change small leather into small leather, make the best use of it and reduce costs
Insist on accounting management
Firmly establish "all costs are available"fall"idea
Based on the post and constantly improving.
Let the small change small leather bear great fruit.
Let’s look at the first continuous casting operation area of the steel plant
What are the tricks?
Oil leakage improvement of main equipment
No.4 continuous caster fan-shaped frame roll gap control valve block plug-in seal,hardPipe joint sealing, drive roller transitionValve blockThere are different degrees of oil leakage in the seal, and the single oil leakage reaches more than 10 barrels in peak period, which affects the quality of billet and brings safety risks.
In order to solve this problem, the steelmaking plant carried out tackling key problems and rectification, mobilized maintenance and spot inspection personnel under the overall organization of a continuous casting operation area, set up a tackling key problem team, found out the causes of seal leakage, formulated corresponding measures, and stopped losses quickly and in time. The research team replaced more than 480 sets of plug-in seals, more than 2,000 rack seals and more than 80 drive roller hoses.Strictly graspThe details of oil leakage and the practical implementation of the landing can ensure the stable and smooth production of the caster and save about 135 thousand yuan/month.
Lubrication and consumption reduction of caster
Grease mainly provides equipment lubrication for each caster during production.letThe key equipment of the caster is kept in good running condition. The first continuous casting operation area of the steel plant consumes about 60 barrels of grease every month, with a total cost of about 160,000 yuan, accounting for 30% of the monthly consumption of "Class 08" productive materials. In order to solve this problem, a series of measures have been taken in a continuous casting operation area:
A set of perfect oil supply system has been reformed in the operation area. When the caster is in production, the oil supply system regularly adds grease to each lubricating point. According to the different positions of the caster, the caster is gradually enlarged without affecting the normal operation of the caster.thatOil supply cycle.
After the implementation of this measure, the consumption of 5 barrels of grease can be reduced every month, and the cost can be saved by 13,400 yuan/month.
The dosage of iron filings is fineminus
A continuous casting operation area firmly establishes "all costs are acceptable"fall"Concept, start on-site production, and dig deep into projects that can reduce costs and increase efficiency. Iron filings are essential when starting the machine.coldMaterial, the monthly consumption of about 10 tons, its role is to shop in the plugging lead.ingotPaperrope, to avoid molten steel burning through the paper rope orblankThe accident of steel leakage caused by poor cooling of the head.
In order to further reduce the consumption of scrap iron, the operation area passes throughWith othersSteel mills benchmark, and organize on-site evaluation of technical and operational backbones to accurately control the consumption of iron filings and changeNarrow edgeThe laying height of the iron filings and the thickness of the cambered iron filings not only ensure that the iron filings completely cover the paper rope, but also ensure thatblankHead cooling effect.
After improvement, everyflowThe consumption of scrap iron is reduced by about 20kg compared with before, and the consumption of scrap iron can be saved by 10 tons per year, and the production cost can be saved by 53,000 yuan.
Be careful and live a tight life
Everyone controls costs and everyone reduces costs.
Deep tillage, cost reduction and efficiency improvement
