Pouring tank with internal heating and internal heat preservation functions

The utility model relates to an internal heating and internal heat preservation pouring tank which is characterized in that a high-temperature-resistant heat preservation layer is arranged on the inner surface of a tank body of the pouring tank, and an armor plate is arranged on the surface of the high-temperature-resistant heat preservation layer; and a plurality of heating pipes are arranged on the inner surface of the armoring plate. According to the pouring tank, the heat source is arranged on the inner wall of the tank, heat loss is prevented through the heat preservation layer, and therefore the heat efficiency is improved. 本实用新型涉及一种内加热内保温的浇注罐，在浇注罐的罐体内表面设有耐高温保温层，耐高温保温层的表面设置铠装板；在铠装板的内表面设有若干根加热管。该浇注罐将热源设置在罐的内壁，并通过保温层防止了热量的散失，从而提高了热效率。
