Abstract

A preheating material tank relates to a device used for steelmaking furnace lining spraying. The preheating material tank comprises an exhaust collector, a material tank, a motor, a supporting roller, a driving gear, a hydraulic cylinder, a shaft, a gear ring, a positioning sleeve ring and a base. The material tank bottom is hinged with a frame on the base through the horizontally disposed shaft, and the supporting roller for supporting the material tank is arranged on the base. A discharge port is provided in the material tank bottom. The positioning sleeve ring is sleeved on the material tank. The hydraulic cylinder bottom is hinged with the base, and a piston rod of the hydraulic cylinder is hinged with the positioning sleeve ring. Stretching and shrinking of the hydraulic cylinder piston rod make the material tank rotate around the shaft. The base is provided with a horizontal track and the exhaust collector is arranged on the horizontal track. When the material tank is horizontally arranged, the exhaust collector is connected with an exhaust port on top of the material tank. The gear ring is fixed on the material tank. The base is provided with the motor. The driving gear is provided on the motor rotary shaft. The driving gear is engaged with the gear ring. The material tank of the invention solves the problem of an unsatisfactory gunning effect as refractory powder cannot be burnt into a molten state in the prior gunning method.

Description

technical field [0001] The invention relates to equipment used for spraying the lining of steelmaking furnaces in iron and steel companies. Background technique [0002] At present, the "flame gunning material formula and method" of the prior art is limited to use on a glass kiln with a temperature of 1200°C. This gunning material formula contains metallic aluminum powder, the melting point of which is only 660°C. In the high-temperature flame zone, the aluminum powder is first melted into a binder, so that the refractory powder sprayed from the normal temperature tank adheres to it. On the lining of the glass kiln. Since the refractory powder has not been melted, the gunning effect is not ideal, so it has not been widely promoted. At present, iron and steel companies are using semi-dry repair methods, all of which are tanks at room temperature, and it is impossible to melt the refractory powder. Contents of the invention [0003] The object of the present invention is ...
