Abstract

The invention relates to the technical field of industrial automation temperature control, and in particular relates to a novel temperature control device and an application method thereof. The novel temperature control device comprises a programmed temperature-controlled meter, a control circuit and an input panel; at least two thermocouple ports are arranged on an auxiliary input module and are electrically connected with thermocouple elements; and a main output module is provided with at least two control output ports which are electrically connected with solid relays. The application method comprises the following steps that: the initial temperature of each time interval, the thermal treatment time after each time interval and a desired temperature in a thermal treatment process are set; and the temperature gradient of the time interval is calculated by a central processor, wherein the temperature gradient is equal to the desired temperature subtracted by the current temperature and divided by the thermal treatment time. A refrigeration control end is electrically connected with a cooling fan of a thermal treatment furnace; and an operator adjusts the heating state or the refrigeration state of the novel temperature control device through a heating / refrigeration switchover device, so that a temperature control defect of heating after excessive refrigeration is overcome.

Description

technical field [0001] The invention relates to the technical field of industrial automation temperature control, in particular to a temperature control device and a usage method thereof. Background technique [0002] The existing program temperature control table has the function of controlling heating and cooling. Most of them are only suitable for single control of heating or cooling. Recently, some manufacturers have launched a program temperature control table with both heating and cooling functions. The stage can be precisely controlled, but the cooling stage is difficult to meet the needs of wire rod heat treatment processing. When the chimney is discharged to the outside, the furnace is cooled first, and the temperature of the furnace is lower than that of the furnace. When the temperature of the wire is equal to the set temperature, the blowing is stopped, but the temperature of the furnace is too low, and the temperature inertia of the furnace drops, so it needs to...
