Abstract

resumo patente de invenção: "método e dispositivo de resfriamento". a presente invenção refere-se a um método para controlar um perfil de uma superfície de um ou mais cilindros de trabalho (8) de um laminador que compreende suprir um refrigerante criogênico (20) para um bocal (23) a uma taxa de fluxo substancialmente constante; e controlar (58) um suprimento de gás (57) para suprir gás (24) para o refrigerante criogênico. se a potência de resfriamento fornecida pelo refrigerante na superfície do cilindro de trabalho (8) for maior do que o resfriamento exigido, o suprimento de gás para o refrigerante é controlado, de modo que refrigerante líquido (20) seja atomizado (27) pelo gás antes de ser aspergido a partir do bocal na superfície do cilindro de trabalho. se a potência de resfriamento fornecida pelo refrigerante na superfície do cilindro de trabalho for menor do que a potência de resfriamento exigida, o suprimento de gás é controlado, de modo que o refrigerante (20) seja suprido a partir do bocal como um líquido (26) para a superfície dos cilindros de trabalho.patent summary: "method and cooling device". The present invention relates to a method of controlling a surface profile of one or more working rollers (8) of a rolling mill comprising supplying a cryogenic refrigerant (20) to a nozzle (23) at a substantially flow rate. constant; and controlling (58) a gas supply (57) to supply gas (24) to the cryogenic refrigerant. If the cooling power provided by the refrigerant on the surface of the working cylinder (8) is greater than the required cooling, the gas supply to the refrigerant is controlled so that liquid refrigerant (20) is atomized (27) by the gas. before being sprayed from the nozzle on the work cylinder surface. If the cooling power supplied by the refrigerant on the working cylinder surface is less than the required cooling power, the gas supply is controlled so that the refrigerant (20) is supplied from the nozzle as a liquid (26 ) to the surface of the work rollers.
