Embodiment Construction

[0010] Such as figure 1 Shown is a kind of preferred embodiment provided according to the present invention, comprises furnace body 10, insulation layer 11, the furnace hearth 1 with heating wire (rod) and the program temperature controller 3 of controlling the temperature in the furnace hearth, in the furnace hearth There is a group of multi-point temperature sensors 2 for measuring the temperature in the constant temperature zone. The multi-point temperature sensor 2 is composed of three temperature sensors 5, 6, and 7 with different lengths; the temperature sensor 5 is the longest and placed in front of the constant temperature zone. On the boundary, the temperature sensor 6 is in the middle, placed at the highest temperature point, and the temperature sensor 7 is the shortest, placed on the boundary behind the constant temperature zone. The temperature sensors 5, 6, 7 are assembled on a junction box 8, and are connected with the program temperature controller 3 through the...

Abstract

The invention discloses a high temperature furnace capable of displaying and controlling a constant temperature area belonging to a heating device, comprising a furnace boy, a heat preservation layer, a hearth with a heating thread (rod) and a program temperature controller that controls the temperature in the hearth. The hearth is provided with a set of multi-point temperature sensor that is composed of more than one temperature sensors with different lengths. Each temperature detecting point of the set of the multi-point temperature sensor is arranged in the constant temperature area and is capable of moving from beginning to end, and correspondingly displays the actual temperature of each point in real time on a display screen. The advantages of the invention lie in that the specific position of the constant temperature area can be regulated randomly and indicated objectively as required and the accuracy of the left position in the hearth of the sample is ensured, which avoids influence of human subjective factor and improves precision and accuracy of detecting result.

Description

technical field [0001] The invention relates to a heating device, which is an improvement to the existing heating device. Specifically, it is a high-temperature furnace capable of displaying and controlling a constant temperature zone. Background technique [0002] The traditional high-temperature furnace is an electric heating furnace. A furnace with a heating wire (rod) is installed inside the furnace, and a temperature sensor is installed in the furnace to indicate the temperature in the furnace. At the same time, the high-temperature furnace is controlled by a program temperature controller. temperature control. During the test, the container (crucible, ash dish, etc.) containing the sample needs to be placed in the constant temperature zone of the furnace, and then the temperature rise test is carried out according to the temperature rise program specified by the national standard. In the above operation process, whether the container containing the sample is left in ...
