Continuous Caster Spray Chamber. Molten steel is continuously cast into slabs or billets. As it leaves the mold it passes through the spray chamber where it is gradually cooled and solidified with water sprays or mist. Conditions in the spray chamber are very hostile to thermometers therefore a specialised product is needed to operate without .
The oil injected at time intervals is then propelled by the air stream along the feed line as droplets in a spiral motion to enter a bearing as an oil spray. Mist Supply. Oil mist is an aerosol mixture of very small oil droplets one to five microns suspended in air with the appearance of smoke. This mist is generated by passing compressed .

May 02 1990 The manual oil coating of steel coils normally involves application of the oil by a low pressure spraying or flooding process from nozzles designed to cover a relatively large area rather than an atomizing or misting spray of the type conventionally employed in paint booths or the like.
Best suited for continuous flat mill backup bearing systems. EP gear oils Used in segregated gear boxes or central gear lube systems in flat rolling mills continuous casters and hot mills. Specialized oils Designed for high speed rod mills – combine wear protection of EP oil with water tolerance of Ramp;O oil.
based oil for cold mills is delivered at a controlled temperature to spray headers. After being sprayed the coolant is collected and returned to the main holding reservoir through a filtration system. Systems custom designed with the coolant flow rate cleanliness and heat dissipation meeting the special requirements of the rolling mill.
Precise control of lubricating applications can reduce oil consumption by up to 90 and can eliminate time consuming cleaning of parts. Precise Uniform Oil Coverage The Spray Lubrication System provides exact lubrication control for can and tab stamping processes.
BOLLFILTERs like the aquaBoll help to reduce the high maintenance and downtime cost by preventing the spray nozzle blockages of cooling water sytsems.. Reference for cooling water filtration in the steel industry. The mill from Thamesteel in Sheerness a specialist manufacturer of steel products mainly derived from recycled scrap metal uses continuous cooling water to keep the bar at the .
Currently rolling mill bearings are mainly used grease and oil lubrication. Most manufacturers are now simple and easy to use grease lubrication lubrication if possible take the oil lubrication technology you can make rolling bearings is the ideal lubrication conditions of
which are more efficient less oil consuming and more flexible. The rolling of high-strength steels poses enormous demands on rolling mills and coolantslubricants. The applied medium must be optimized for all rolling applications and it must be suited to meet the targeted quantity and quality requirements for various steel grades.
Applications. MORGOIL series oils are primarily recommended and are used almost exclusively for rolling mill applications including Back-up roll bearings of rolling mills particularly bearing systems where either a single or dual tank is employed

Specialized oils Designed for high speed rod mills – combine wear protection of EP oil with water tolerance of Ramp;O oil.
Steel Hot Rolling Mill Application Overview Temperature Control in the Hot Rolling Mill The Hot Rolling Mill is used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip plate rod bar wire or shape rails and H-beams.
Mar 01 2000 Pinions range from 2 to 4-ft pitch diameter and 4 to 10 ft long. A pinion with integral shaft weighs 10000 to 20000 lb. The gears range from 5 to 15-ft pitch diameter and 2 to 5-ft face width .

Rolling Mill Technology. Rolling Mill technology is a core competency of IMS. This is where IMS truly got its start and remains at the heart of what we do. When it comes to Rolling knowledge and experience IMS is a world leader. IMS was one of the first companies to pioneer the application of PLC systems to all aspects of rolling mill control.
John G. Lenard in Primer on Flat Rolling Second Edition 2014 2.7 Generation III – Coil Box Hot Strip Mills. In the 1970s Stelco of Canada developed the hot coil box designed for installation in hot strip mills ahead of the finish mill for coiling the transfer bar from the roughing mill and uncoiling it into the finishing mill. The coil box reduced the distance between the roughing mill .
Oct 01 2020 The application of oil lubrication in hot strip rolling has many advantages for the process i. e. reduced roll force reduced energy consumption better strip surface quality and reduced roll wear.On the other hand oil lubrication may also induce severe disturbances for several control loops in a tandem hot rolling mill which can reduce the final strip quality or might even jeopardize a .
