Abstract: PURPOSE: An asymmetric processing apparatus and method and a material processed using the same are provided to improve room-temperature formability of extruded-rolled materials by arranging a slip system to easily induce shear transformation at room temperature. CONSTITUTION: An asymmetric processing method comprises a step of pushing out a material through dies(230) with an extrusion hole having an asymmetric shape in the planar direction of the material to induce internal shear transformation along the thickness of the material and extrude the material(250), thereby obtaining an extruded material(260) and a step of pushing the extruded material between first and second rolls(101,102) with difference diameters to induce shear transformation on the extruded material and roll the extruded material, thereby obtaining a rolled material. The extrusion hole of the dies includes a tapered portion(234) varying in width in the extrusion direction of the extruded material.

Abstract: PURPOSE: A purification apparatus of exhaust gas and a baffle of the apparatus are provided to accelerate the separation of exhaust gas and impurities by installing baffles for guiding the rapid direction change of air currents. CONSTITUTION: A purification apparatus of exhaust gas includes a first duct part(10), an impurity receiving part(30), a second duct part(20), and a first baffle(B11). The first duct part guides exhaust gas containing impurities toward a first direction. The impurity receiving part is formed at the lower part of the first duct part, and receives impurities from the exhaust gas. The second duct part is connected to a purified gas outlet(H) which is formed at the lateral side of the first duct part, and guides purified gas to a second direction. The first baffle guides the exhaust gas from the first duct part to the second direction of the second duct part. The first baffle is protruded into the first duct part, and has at least one round surface(S).
