Description
Изобретение относитс к контролю металлических изделий в нроцессе нагрева и может примен тьс в черной и цветной металлургии .The invention relates to the control of metal products in the heating process and can be used in ferrous and non-ferrous metallurgy.
РЬвестен сиособ контрол прогрева металлнческих .изделлй, со-сто щнй в том, что измер ют температуру поверхности слитка лосле прокатных клетей стана и о степени прогрева суд т по разности температур в различных точках пол .The heat treatment method for controlling the heating of the metal extract, is based on the fact that the surface temperature of the ingot is measured by the rolling mill stands and the degree of heating is judged by the temperature difference at different points in the floor.
Однако существующим способом степень прогрева металла можно определить не в печи в процессе пагрева, а при прокатке слитка.However, using the existing method, the degree of metal heating can be determined not in the furnace in the process of heating, but during the ingot rolling.
Цель предлагаемого способа - повысить точность контрол температурного состо ни металлического издели .The purpose of the proposed method is to improve the accuracy of controlling the temperature state of a metal product.
Это достигаетс тем, что в процессе иагрева измер ют изменение размеров издели и стабильность температуриого состо ни определ ют по прекращению изменени размеров издели при посто нной температуре его поверхности.This is achieved by measuring the change in the dimensions of the product and the stability of the temperature state in the process of ignition, by ceasing the change in the dimensions of the product at a constant temperature of its surface.
На чертеже иллюстрируетс пример реализации предлагаемого способа.The drawing illustrates an example implementation of the proposed method.
Датчик 1 и вторичный регистрирующий прибор 2 измер ют температуру поверхности издели 3, расположенного в рабочем пространстве 4. Измерительные зонды 5 ввод т в рабочее пространство печи и привод т в контакт с нагреваемым изделием 3. В процессе li arpeBa, |зследст,зие тармичеокОго |р;1сширОои металла, размеры издели измен ютс . С помощью датчиков перемен енн 6 и блока регистрации 7 измер ют величину неремет.чени зондов 5. Прекращение неремен1ени зондов 5 при посто нной температуре поверхностн издели свидетельствует об окончапг.п прогрева издели , то есть о стабилизации его темнературного пол .The sensor 1 and the secondary recording device 2 measure the surface temperature of the product 3 located in the working space 4. The measuring probes 5 are introduced into the working space of the furnace and brought into contact with the heated product 3. In the process of li arpeBa, | p; 1 metal wide; product dimensions vary. Using the variable sensors 6 and the recording unit 7, the value of the non-timing of the probes 5 is measured. Termination of the non-tempering of the probes 5 at a constant temperature of the surface product indicates that the product has warmed up, i.e. it stabilizes the temperature of the field.
При м е р. Коэффициент линейного расщирени железа равен 12- . Следовательно при нагреве железного издели длиной 1,0 м на 1000° С его размер увеличитс на 12 мм. При измерении длины издели с точностью ±0,1 мл1 его средн температура будет определ тьс с точностью +8° С.An example. The coefficient of linear expansion of iron is 12. Consequently, when the iron product is 1.0 m long by 1000 ° C, its size will increase by 12 mm. When measuring the product length with an accuracy of ± 0.1 ml1, its average temperature will be determined with an accuracy of + 8 ° C.
