SU1614867A1 - Installation for removing dust and steam from rolling mill working stand - Google Patents

Abstract

The invention relates to devices that remove the hazards from their places of formation, and can be used to remove dust and steam from the rolling stands. To reduce energy consumption, the installation is equipped with a valve 5 with a rod, while the rod is movably mounted on a lifting and swinging table 6 and valve 5, and the valve is hingedly suspended directly below the lower roll of the cage on an axis placed parallel to the axis of the rolls. 1 il.

The invention relates to devices that ensure the removal of hazards from their formation.

The purpose of the invention is to reduce energy (cost).

I The drawing shows the installation, a cross-sectional view.

i The installation for, for example, a three-roll working stand consists of an exhaust system (not shown) connected to the hydraulic removal tunnel of scale 1, a valve 2 suspended globally on axis 3 parallel to the axis of the work rolls 4, and rod 5 movably mounted on the rear lift (jMHO-swinging table 6 and valve 2. At the top horizon, roll 7 goes to the next lift-swinging table 8, which is equipped with overhangs 9.

The installation works as follows.

When the roll 7 comes out on the lower horizon to the rear lift-swinging lap 6 (shown with a dotted line), the valve 2 by the rod 5 is brought to the position shown in the drawing also by the dot 1INIA, and thus prevents suction; the stand and concentrates the entire volumetric flow rate of the exhaust system on the exit side of the stand, where at the moment there is a release of hazard. When the roll out to the front lift-swinging table on the upper horizon, valve 2 stem 5

is brought to the position shown in the figure by solid lines, and the entire volumetric flow rate of the exhaust system is concentrated on the other side of the cage, which is the exit during this period.

In order to avoid unproductive suction from under the front lift-swing table 8 when rolling on the upper horizon, the table is equipped with overhangs 9.

The proposed plant for removing dust and steam from the rolling mill stands will reduce energy consumption compared to the known one by reducing the capacity of the exhaust system and heat consumption to compensate for heat losses with exhaust air, and improve working conditions.

Claims (1)

Claims An installation for removing dust and steam from the rolling mill stands, containing one rolling mill rolls, lifting and tilting tables and a scale water removal tunnel connected to an exhaust ventilation system, in order to reduce energy costs it is provided with a hinge fixed on the axis with a valve having a rod, movably fixed on the valve and one of the swinging tables, while the axis on which the valve is fixed is placed under the bottom mill roll parallel to the axis of the roll.
