Definitions

  • This invention relates to a composition of oil suitable for hot rolling of steel and its alloys.
  • the oil composition forms an oil-in-water dispersion when mixed with water using proper agitation and provides adequate lubricity and load carrying capacity during rolling of steel slab/sheets.
  • the hot rolling process is one of them. This process reheats, rolls and coils the steel.
  • rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process.
  • the primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through successive rolling mill stands driven by motors and finally coiling up the lengthened steel sheet for transport to the next process.
  • slabs of thickness of about 250mm are heated in a furnace and are reduced to 30 to 60mm in thickness after passing through the roughing mill, and then further reducing it to within a range of 0.8 to 25.4mm by rolling in the finishing mill.
  • hot rolled products are rails, structurals, concrete reinforcing bars, wire rods, plates, sheet and strip.
  • the plates, sheet and strip products are used to manufacture pipes and tubes, construction materials and body panels and stampings for the appliance and automotive industries.
  • the temperature encountered in the hot rolling operation estimated to be very high. It is therefore essential to provide a means of controlling the temperature of the rolls in order to improve their life. Cooling is therefore necessary to control the temperature of the work rolls and at the same time lubrication is equally important for preventing the metal-to-metal contact between work rolls and the work piece.
  • the hot rolling oil is, therefore, required to fulfil two key properties i.e., lubrication and cooling. For these reasons dispersion of oil in water are preferred for the use of hot rolling operations as cooling properties is derived through water while oil separated from dispersion during use provide necessary lubrication requirement.
  • Hot rolling oil is the application of a dispersion, which is a mechanical mixture of oil (>1%) and water ( ⁇ 99%) in the hot rolling process.
  • the typical application involves 40-50 litres per minute at 5 bar.
  • Oil is injected into the water stream and mixed by a static tube mixer to form dispersion that is sprayed onto the work roll/backup roll.
  • the goal is to form a strong lubricating film on the roll surface.
  • the most important function of the rolling lubricant is to reduce the coefficient of friction during the actual rolling to the desired level.
  • the better surface finish of the rolled product which is largely dependent on the rolling oil formulation is the customer requirement.
  • a good dispersion of hot rolling oil should provide desired lubrication to the metal as it passes through the rolls, reduce roll wear, provide sufficient cooling to the rolls and metals, improve strip quality and eliminate edge seam/scale defects.
  • a good dispersion also increases productivity through extended campaign length, prevents work-roll cost, has the ability to roll harder grades with restricted power loads and as a result reduces power consumption. At the same time, a good dispersion also decreases maintenance costs.
