Description
Technical field
The present invention relates to cold rolling mechanical equipment technical field, specifically a kind of cold mill complex with fire-proof function.
Background technology
Cold-rolling mill is the machine that I grade of hot rolling Q235 round steel is gone out to the spiral helicine reinforcing bar of finished product likeness in form through cold drawn, cold rolling
Equipment.Cold rolling mill equipment can carry out cold working simultaneously during cold rolled reinforcing steel bar with ribs is rolled to the direction of warp and weft of mother metal,
On the premise of the relative equilibrium and stabilization that retain former kernel of section region product body, while anti-position, resistance to compression is improved, still retain foot
Enough extension properties.
The general Aided design of cold mill complex takes out nebelwind machine, and the flue for taking out nebelwind machine is generally designed to be square, and unit exists
, it is necessary to which strip and roll are cooled down and lubricated during milled sheet band, thus a large amount of emulsions are sprayed, so as in milling train
Area generates substantial amounts of mist of oil gas, and the mist of oil is mainly made up of three parts, and Part I is to answer to do caused by jet impact
Net vaporific coolant mist of oil, granulometric range account for more than the 96% of total mist of oil amount between 20-30 μm；Part II is heating
Cause evaporation or calcination and caused smog, granulometric range is between 0.01-5 μm；Some is contained caused by rolling
The mist of oil of metallic dust, account for the small part of total mist of oil total amount.80 DEG C of the general ＜ of mist of oil temperature, concentration 100-300mg/
m³.Because the main component of mist of oil is oil, steam and iron powder etc., accumulation for a long time can form greasy filth in flue, and the greasy filth is
Combustible material, typically also standard configuration has the fire resistant doorsets of louver-type to flue, but such fire resistant doorsets have three：1st, with cigarette
Greasy filth is cumulative in road, and the rotating mechanism of the fire resistant doorsets of louver-type can be more and more insensitive, causes switch difficult, cut-off
Exist in name only；2nd, greasy filth is more in flue, and it is bigger to occur the hidden danger of fire, while can reduce and take out nebelwind engine efficiency, it is therefore desirable to
Operating personnel's cycle, which enters, wherein clears up greasy filth in flue；Because the fire resistant doorsets of louver-type form in flue
Obstacle, greasy filth can only be cleared up from middle toward two, considerably increase cleaning difficulty and workload；3rd, the fire prevention of louver-type
Door has electronic, pneumatic and manual, and electronic is often to ensure to have alreadyed switch off power supply safely after the condition of a fire occurs, is lost dynamic
Power；Cylinder seal part can be destroyed and pneumatic cylinder needs cyclic check to safeguard, during high temperature so that action is unreliable；Manual
Operating mechanism is often designed on the side of valve, and flue is more in the air, inconvenience up and down, affects fire extinguishing opportunity adversely.Therefore, research and develop
A kind of cold mill complex with fire-proof function is urgent problem to be solved of the present invention.
The content of the invention
Present invention aim to solve above mentioned problem existing for the fire resistant doorsets of current louver-type, there is provided one kind tool
There is the cold mill complex of fire-proof function.
The present invention concrete scheme be：A kind of cold mill complex with fire-proof function, the cold mill complex is interior to be provided with flue,
The middle part of the flue top surface is provided with sluice gate, positioned at both sides at sluice gate provided with the left socle perpendicular to flue and right branch in flue
Frame, the bottom of the left socle and right support is parallel with stack base, is extended at the top of left socle and right support outside flue
One section, be provided with track in the left socle and right support, built with lock gate hatch, the top of left socle and right support is provided with horizontal track
Support, the centre of the lateral frame and right-hand member are mounted on pulley, and manual hoist, the manual hoist are provided with ground
It is connected by steel wire rope with pulley, left hanger and right hanger, the left side has been arranged symmetrically at left and right sides of the bottom of the lock gate hatch
Hanger and right hanger are connected by steel wire rope with the suspension hook on manual hoist.
Preferably, the lock gate hatch has internal layer, intermediate layer and outer layer three-ply sandwich structure, and the internal layer and outer layer are steel
Plate, intermediate layer are refractory material.
Further, left hanger and right hanger, the left hanger have been arranged symmetrically at left and right sides of the middle part of the lock gate hatch
It is connected with right hanger by steel wire rope with the suspension hook on manual hoist.
The present invention it is ingenious in design, it is simple in construction, directly perceived, using, it is easy for installation, occur the condition of a fire when can with timely processing, put down
When Shi Zhengchang is produced and cleared up, only lock gate hatch need to be manually pulled on flue hoist engine, flue not produced permanent
Cut-off, do not influence daily cleaning.Once the generation condition of a fire, being fallen to lock gate hatch in flue using manual hoist, prevent empty
The entrance of gas, you can cut-out flue, prevent the condition of a fire from further expanding, protection memorial archway safety.The present invention uses manual hoist,
Independent of other energy mediums, and manual hoist is installed on ground, efficiently avoid occur the condition of a fire when power-off can not
Using limitation, possesses the prospect of the application in same type enterprise.
