Work Cooling Devices TRIZ Cases

Direct inlet flow measurement and valve feedback keep strip cooling rates stable despite pressure loss changes when supply units switch on or off.

Hollow and position-specific nozzle cross sections widen jet impingement to cool flat rolling stock more uniformly and reduce flatness errors.

A concave removable plate keeps the roll-to-cooler gap in range, sustaining a turbulent water cushion across varying work roll diameters.

A compact casting-rolling line cuts transport to 50 m or less, reducing heat loss while enabling slab separation for flexible batch production.

An orifice in the larger-diameter section evens pressure and flow in strip cooling tubes, improving cooling uniformity with simpler construction.

A funnel straight mold, vertical strand guide, and reheating scheme improve thin slab solidification and cut energy use in compact hot strip production.

Interstand and exit cooling with trimming and drying gives aluminum hot strip mills tighter temperature-time control and better alloy properties.

Isolation valves near water boxes and VFD pumps cut cooling pressure lag, shorten transition length, and improve metallurgical uniformity.

An internal orifice and stepped tube diameter improve cooling-fluid pressure and flow uniformity for hot-rolled metal strips at lower cost.

A two-chamber cooling bar layout speeds water emptying, cuts dripping time, and keeps cooling distribution uniform during rolling.

A variable slot cooling bar adjusts nozzle width during operation to keep metal cooling uniform despite pressure changes and edge flow effects.

Adjustable gaps and squeezing rollers recirculate cooling fluid to reduce edge runoff and keep moving refrigerated products uniformly cooled.

Movable cooling bar sections adjust slot width in real time to balance cooling power across metal sheets and avoid uneven temperature profiles.

A two-chamber coolant layout speeds draining, stops post-shutdown dripping, and keeps spray cooling uniform for rolled material.

Supercritical fluid diffuses heat uniformly inside the roller, avoiding rust and end-to-end temperature variation in precision processing.

Upstream coolant sensing and valve characteristics enable precise metal strip cooling flow control without costly flowmeters or overshoot.

Independent nozzle zones and temperature feedback vary coolant across strip width to minimize edge-to-center temperature deviation.

Side-positioned near and far nozzles remove cooling water across steel sheet width while preserving cooling space and reducing water use.

A slit-shaped rectangular nozzle forms a continuous strip jet that removes slab scale at 5-50 bar while cutting energy use and temperature loss.

Liquid nitrogen cooling during rolling refines pure titanium grains below 100 nm, resolving strength and ductility trade-offs.

Inclined round nozzles eject rodlike coolant flows that collide and dam each other, eliminating uneven cooling caused by residual coolant accumulation.

A scale removal device with a narrow exit fissure creates a high-energy water blade that removes scale while minimizing thermal impact on thin metal products.

Nozzles spray coolant at an acute angle against the running direction of a metal strip to create a turbulent flow field.

Opposing cylindrical nozzles supply cooling water to both surfaces of a moving steel plate, maintaining uniform temperature without separate waiting positions.

Differentiated cooling preserves edge temperature to prevent cracking and reduce energy consumption.

Pressurized fluid injection into the coolant chamber interrupts flow from J-shaped outlet pipes, eliminating run-on and improving cooling consistency.

Overlapping water-blocking nozzles create a continuous fluid barrier across the steel sheet width to prevent leakage during high-density cooling.

Mechanical impact rollers remove oxide scales from hot rolled slabs without the thermal shock and surface damage caused by high-pressure water descaling.

Segmented spray bars with independent valve control adjust flow rate profiles to eliminate thermal ridges on flat rolled products.
