The invention relates to the field of sintering kilns, in particular to a roller kiln for producing microcrystalline foam ceramic. The roller kiln for producing the microcrystalline foam ceramic comprises a preheating zone, a high temperature zone, a heat preservation zone and a cooling annealing zone. A burner of the preheating zone is arranged below a product. A burner of the high temperature zone is arranged above the product, the spraying direction of the burners is perpendicular to the moving direction of the product, and the caustic surface of the burner is arranged like a Chinese character 'pin'. An impulse burner is adopted as a burner of the heat preservation zone, a transition zone is arranged between the heat preservation zone and the cooling annealing zone, and the transition zone is an air brattice formed by a hot air burner. The hot air burner is connected with an air pipe, and the air pipe is further connected with the cooling annealing zone and the heat preservation zone. An air blower and a heating box are also arranged inside the air pipe, an air inlet of the air blower is connected with the cooling annealing zone, and an air outlet of the air blower is connected with the transition zone and the heat preservation zone through the heating box. According to the roller kiln for producing the microcrystalline foam ceramic, heated temperature of the microcrystalline foam ceramic is stable, temperature difference is small, product quality is improved, and production efficiency is greatly improved. Due to the fact that a hot air circulating system is adopted, energy consumption is reduced, and the roller kiln for producing the microcrystalline foam ceramic is environmentally friendly and saves energy.

The invention relates to a feeding tank temperature control method and system. The method includes the steps that in each time of pulse heating in the process of pulse heating on a feeding tank according to a preset period, a controller receives a real-time temperature detection value sent by a temperature sensor and corresponding to the time of pulse heating; the controller determines corresponding heating coefficients according to numerical ranges where difference values between a process set value and the real-time temperature detection values are in, wherein the numerical range where a smaller difference value is in corresponds to a smaller heating coefficient, and the numerical range where a larger difference value is in corresponds to a larger heating coefficient; the controller calculates the heating temperature adopted in a next time of pulse heating according to the difference values and the corresponding heating coefficients, and the next time of pulse heating is carried out according to the heating temperature. The feeding tank temperature control method and system can overcome shortcomings existing in impulse type step-by-step heating in the prior art, improve feed liquid heating efficiency and enhance heating effects.
