An in-line four-roll rolling device that can automatically adjust the pressure and thickness of the rolls

Abstract

The invention proposes an in-line four-roll rolling device that can automatically adjust the pressure and thickness of the rolls, including: an in-line four-roll rolling machine, including a roll press frame, an upper support roll adjustment mechanism, an upper support roll, an upper work roll, Lower work roll, lower support roll, pressure adjustment device and power unit; online thickness measurement device, matched with in-line four-roller press, including online thickness measurement device frame, grating scale displacement sensor, pressure wheel and online thickness measurement support roll . Beneficial effects of the present invention: the support roll provides roll pressure for the work roll, which reduces the end load of the work roll, makes the pressure of the work roll more uniform, and the thickness of the catalyst plate after rolling is also more uniform, prolonging the service life of the work roll, and at the same time Cooperating with the online thickness measuring device, it not only greatly reduces the error caused by manual measurement, and will not cause damage to the catalyst plate, but also the pressure adjustment device can adjust the pressure in real time, and then adjust the roll gap of the working rolls, avoiding the hysteresis and low pressure caused by manual operation. Accuracy, reduce the scrap rate.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an in-line four-roll rolling device that can automatically adjust the pressure and thickness of the rolls. Background technique [0002] Nitrogen oxides (NOx) are one of the important precursors that cause pollution events such as acid rain, photochemical smog, and smog. At present, NOx emission control technologies include combustion control and flue gas post-treatment. Selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR) are currently widely used flue gas post-treatment denitrification technologies. Catalyst It is the core of SCR technology, and the plate catalyst is a kind of catalyst. [0003] The plate-type catalyst is based on a stainless steel metal mesh plate, and TiO 2 , V 2 o 5 The mixture of etc. is rolled and coated on the stainless steel screen, and after pressing and calcining, the catalyst plate is composed of a cata...

Problems solved by technology

This detection method, on the one hand, has a large manual measurement error, and on the other hand, there is a certain delay from the measurement result to the adjustment of the roller gap. These problems seriously affect the qualified rate of the catalyst.
