Abstract
The invention relates to a lubricating oil adding method, in particular to a quantitative oil adding method of a work roll bearing. According to the quantitative oil adding method of the work roll bearing, a bracket is arranged in the position of the work roll bearing where the lubricating oil needs to be added, an oil nipple is arranged at the filling-up area of the work roll bearing, the oil nipple is connected with a hose, the hose is connected with a lubricating oil tank, the oil nipple is fixed to the bracket, a flow valve is arranged on the oil nipple, an electromagnetic valve is arranged on the flow valve, and the flow valve and the electromagnetic are connected with a control device through electrical signals. By means of the quantitative oil adding method of the work roll bearing, quantitative oil adding of the work roll bearing is achieved, the history of oil adding depending on experience is changed, and the difficult problem is well solved by the quantitative oil adding.
Description
Technical field
The present invention relates to a kind of lubricating oil filling method, specifically a kind of workroll bearing quantitative refueling method.
Background technique
Dry oil lubrication mainly concentrates on slightly, on precision rolling working roll bearing, every day, roll change was 8-9 time, need buy oil to 14 of lower machine workroll bearing casees at every turn, the stable operation of workroll bearing after machine in assurance.
Rolling bearing during steel rolling, is bearing all the time huge radial pressure and the powerful impact force to bearing from blank on milling train; Simultaneously the working environment of rolling bearing is also quite severe, and the brown iron oxide that the roll cooling water of high pressure, dephosphorization water and surface of steel plate produce can be invaded in bearing constantly, once bearing burnt will bring scrapping of production suspension induced losses and bearing, casing, roll.Along with requirements such as high strength steel and general steel thinnings, for the lubricating requirement of rolling bearing, higher requirement is also proposed.
Due to bearing unit price higher (unit price surpasses 200,000 yuan), in metallurgical system, on-the-spot installation amount is large, and with 2250 line wall scroll Hot Line statistics, the workroll bearing total value of on-the-spot operation is over 7,000 ten thousand yuan.If oil beats that I haven't seen you for ages causes bearing oil starvation, bearing in batch damages oil starvation in advance, oil starvation saggar even, and the scrapping and rolling line fault time, steel scrap etc. of related bearing housing and roll, these huge losses are that any entreprise cost is all unaffordable.So would rather oil in enterprise beat some more, the risk that brings of minimizing oil starvation.But can bring the useless lubricating grease after consumption to be substantially all washed in the cooling water of rolling line, water system is polluted, bring the pressure in technology and fund to the water treatment of water-supply plant, water quality is also brought impact to strip surface quality simultaneously, on-the-spot greasy dirt is large simultaneously, a series of problems of management of cleaning difficulty, the cost of oil consumption simultaneously tool height not under.
Owing to reduce producing and the requirement of cost of equipment maintenance, in the urgent need to further improving the standard of lubricating rollers, to improve constantly greasy property, extend bearing working life, reduce and consume, reduce and pollute, increase benefit.
Summary of the invention
Technical problem to be solved by this invention is: how to realize the quantitative refueling to workroll bearing, prevent that operator from buying oil less or buying oil more, reach the object that guarantees best volume read-out.
The technical solution adopted in the present invention is: a kind of workroll bearing quantitative refueling method, the position mounting bracket that needs lubricating oil filling at workroll bearing, fuel filler neck is installed at workroll bearing filling-up area place, fuel filler neck connecting hose, flexible pipe connects lubricating oil tank, and fuel filler neck is fixed on support, and Flow valve is installed on fuel filler neck, solenoid valve is installed on Flow valve, and Flow valve is connected control gear with solenoid valve by electrical signal.
As a kind of optimal way: it is a plurality of that workroll bearing needs the position of lubricating oil filling to have, and a plurality of flexible pipes are connected to same lubricating oil tank by one-way valve.
As a kind of optimal way: control gear is controlled solenoid valve according to the difference that need to refuel in the different position of different operating roller bearing and refueled.
The invention has the beneficial effects as follows: the present invention has realized workroll bearing quantitative refueling, changed the history of in the past refueling by rule of thumb, and quantitative refueling will solve this difficult problem well.After improving, realize the quantification of mending fat to bearing, improve successful, be embodied in environmental protection, equipment, 5S, safely, fall originally, put forward the aspects such as effect, there is good comprehensive benefit.
Embodiment
First near position mounting bracket each needs the workroll bearing of lubricating oil filling, fuel filler neck (the one section hard tube of fuel filler neck for being connected with filling-up area) is installed at workroll bearing filling-up area place, fuel filler neck is fixed on filling-up area by support, after being installed on fuel filler neck connecting hose, flexible pipe, one-way valve is connected to lubricated mailbox, Flow valve is installed on fuel filler neck, solenoid valve is installed on Flow valve, and Flow valve is connected control gear with solenoid valve by electrical signal.It is a plurality of that workroll bearing needs the position of lubricating oil filling to have, and a plurality of flexible pipes are connected to same lubricating oil tank by one-way valve.
Secondly at control gear, be a computer, the difference that computer need to refuel according to each workroll bearing, controls solenoid valve and Flow valve each workroll bearing is carried out to quantitative refueling.
Shanxi Taigang Stainless Steel Co., Ltd is used the benefit obtaining after the present invention as follows:
Economic benefit calculation:
1) reduce the economic benefit that the amount of buying oil is brought: 1,490,000 yuan/year
Smelter work roll is lubricated is now still sulfoacid calcium with grease substantially, and unit price higher (69 yuan/KG), monthly to save 1.8 tons of calculating, will save 1,490,000 yuan the whole year.
2) on-the-spot greasy dirt situation greatly reduces, and has improved the roller region greasy dirt situation everywhere that in the past falls, and has promoted on-the-spot 5S managerial skills; Monthly reduce oil-containing rag, anti-skid cloth, more than 50% generation of oil-containing sawdust refuse for cleaning, 120,000 yuan of year cost-saved expenses simultaneously.
3) promoted this materialization of site safety level.This refuels place, and greasy dirt was large in the past, handling is frequent, and furthermore the complicated site environment such as overhead traveling crane cross-operation, takes after new process, has fundamentally solved potential safety hazard.
4) reduce emulsification and loss, reduce the pollution of grease to water, improve water treatment situation, significantly alleviate the burden that water-supply plant is processed hot rolling mill circulating water, 240,000 yuan of annual minimizing treatment costs.
5) improved water quality, the improvement of water quality finally can improve the quality of surface of steel plate, especially stainless steel surfaces quality.
In sum, total can be brought 1,850,000 yuan of direct economic benefits, and quality promotes in addition, site environment improves, the lifting of this materialization of safety level etc. do not count.
