Abstract

The utility model provides a novel metallurgy electric furnace controller. The novel metallurgy electric furnace controller comprises a controller body, an intelligent temperature controller, a voltmeter, an ampere meter, a power switch, a circuit control relay, a binding post, a thermocouple, an over-temperature alarm and a high-temperature protective layer, wherein the intelligent temperature controller, the voltmeter, the ampere meter and the power switch are arranged on the front surface of the controller body, the over-temperature alarm is arranged on the side surface of the controller body, the binding post is arranged on the rear surface of the controller body, the circuit control relay is arranged inside the controller body, the intelligent temperature controller is connected with the circuit control relay, the over-temperature alarm and the thermocouple are connected with the intelligent temperature controller, the voltmeter and the ampere meter are connected to the thermocouple, and an outer shell of the controller body is the high-temperature protective layer. According to the novel metallurgy electric furnace controller, due to the fact that the over-temperature alarm is additionally arranged, when an electric furnace breaks down and the temperature rises suddenly, the over-temperature alarm gives an alarm, the operation safety of a device is improved; the high-temperature protective layer is further additionally arranged, the device is not influenced by the hot environment, and the detection precision is improved.

Description

A kind of metallurgical electric stove controller

Technical field

The utility model relates to electric furnace control technology field, relates in particular to a kind of metallurgical electric stove controller.

Background technology

temperature is one of thermal parameter very important and general in industrial circle, the process of any physical and chemical changes all be unable to do without the variation of temperature, therefore the control for temperature is the vital task of automation, electric furnace is widely used in metallurgy, the industries such as chemical industry, metallurgical electric furnace is large-scale energy consumption equipment, because electric furnace thermal inertia in the process of operation is large, hysteresis is serious, there are a lot of uncertain factors, cause controlling unstable for temperature, even out of control, therefore about how improving the temperature of metallurgical electric furnace, thereby the problem that improves the runnability of equipment is all the problem that the technical staff makes great efforts to solve all the time, temperature control device is in carrying out temperature controlled process, be in hot environment, cause the accuracy of temperature control device to reduce, when electric furnace breaks down and during the excess Temperature that causes detecting, also can affect the stability of controller operation.

Summary of the invention

according to above technical problem, the utility model provides a kind of control easy, stable metallurgical electric stove controller, comprise the controller body, intelligent temperature controller, voltmeter, ammeter, power switch, circuit control relay, binding post, thermocouple, it is characterized in that: also comprise overtemperature alarm, high hat resistant cover, the front of described controller body is provided with intelligent temperature controller, voltmeter, ammeter, power switch, the side of described controller body is provided with overtemperature alarm, the inside of described controller body is provided with circuit control relay, the back of described controller body is provided with binding post, described thermocouple is connected to intelligent temperature controller by binding post, described voltmeter is connected to connect the end that wire is connected to thermocouple with ammeter, described intelligent temperature controller is connected with circuit control relay, described overtemperature alarm is connected with intelligent temperature controller, the shell of described controller body is high hat resistant cover.

The beneficial effects of the utility model are: the utility model has increased overtemperature alarm on original basis, when electric furnace breaks down, when in stove, temperature raises suddenly, the electric furnace control relay disconnects, when no longer giving heating by electric cooker, overtemperature alarm can give the alarm, in order to remind the staff to cut off the power supply of electric furnace, has improved the equipment Operation safety; The utility model has also increased high hat resistant cover on original basis, when controller is worked in hot environment, within the temperature of controller is remained on an allowed band, make controller not be subjected to the impact of hot environment when work, has improved accuracy of detection.
