Problems solved by technology
[0002] At present, the thermal analysis method is widely used to measure the temperature of the primary crystal of a substance. Since sampling, cooling, crystallization, and remelting will change the composition of the melt, it is easy to cause accidental errors in the measurement results, and the analysis results have little effect on actual production. In the production process, the liquidus temperature of the electrolyte, or the primary crystal temperature of the electrolyte, is an important parameter, especially in the aluminum electrolysis system. It directly affects the operating temperature of the aluminum electrolysis process, and the accurate measurement of the primary crystal temperature Temperature, controlling the electrolysis temperature, and adjusting the superheat to achieve the best state are the primary goals of energy saving and consumption reduction in the electrolytic aluminum industry. The traditional method of measuring the primary crystal temperature has low automation, poor heat preservation effect, and poor protection measures. Not only is it prone to corrosion corrosive gas, greatly corrode the test equipment, pollute the working environment, the measurement method is too simple, it is easy to accidentally injure the operator, and it is extremely unsafe to operate

Embodiment Construction
[0029] Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:
[0030] A method for measuring the primary crystal temperature of an electrolyte, such as figure 1 Shown, described measurement method comprises the following steps:
[0031] 1) Power on the equipment, start the electric furnace open button, and the system will automatically heat up to the set temperature T;
[0032] 2) Input parameter sample number;
[0033] 3) Determine whether to start the system button;
[0034] 4) When the system button is not activated, the system is in a waiting state, and then judge whether the waiting time exceeds N seconds? When exceeding N seconds, open the protective cover of furnace mouth 40, descend furnace cover 41;
[0035] 5) When the system button is activated, the furnace cover 41 is automatically lifted;
[0036] 6) Then, the protective cover 50 automatically closes the furnace hearth mouth;
[0037] 7) Open...
