Description

technical field [0001] The invention relates to the technical field of amorphous strip production, in particular to a cooling roll guide device for amorphous strip production. Background technique [0002] The molten steel is rapidly cooled at a speed of millions of degrees per second. It only takes one thousandth of a second to reduce the molten steel of 1300 ° C to below 200 ° C. The cooling process is very fast, and the atoms are solidified before they can be rearranged. An alloy in which the atoms are arranged in a random state. An amorphous alloy is thus produced, forming an amorphous ribbon. [0003] In the production of amorphous ribbons, cooling rolls need to be used for high-speed cooling. At present, the cooling water circuit structure in the core of the cooling rolls is that the cooling water directly enters the central hole of the main shaft, and then comes out from the radial hole of the main shaft and enters the radial shape in the support plate. inside the h...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a cooling roll deflector for the production of amorphous strips, which can greatly reduce the flow resistance of cooling water, reduce the mechanical energy dissipation and temperature rise caused by fluid viscosity, and reduce the water flow of the cooling roll. The pressure difference is also greatly reduced, which improves the cooling effect of the cooling roller, and solves the problem that the traditional waterway structure is in the annular space, and only the friction force of the side wall of the space drives the water flow to rotate, so the angular velocity of the water flow lags far behind The angular velocity of the radial hole causes the resistance of the water flow, which leads to an increase in the pressure difference between the inlet and outlet of the waterway, which not only increases energy consumption, but also causes attenuation of the cooling effect of the cooling roller.
