The utility model belongs to the field of metallurgical refractory materials, and particularly relates to a light burnt magnesia ball. It is made by using ordinary light-burned magnesia powder and pressing the ball after mixing. Light burned magnesia balls are mainly used for converter steelmaking, slag splashing to protect the furnace, which can improve the life of the converter. The preparation of light burnt magnesia ball is to add 80% light burnt magnesia powder to 20% water, put it into a milling machine, roll, stir, and mix for 15～20min to form a mixture, and then send the product through the belt conveyor to the ball press machine , And then stacked. The finished light-burned magnesia ball is ready for sale after being dried in the shade for 48 hours and forming strength. Due to the defects in the structural design of the existing light-burned magnesia balls, the effect of improving the viscosity of the slag in the converter slag splash protection operation is not satisfactory.
1. A light-burned magnesia ball, comprising a ball (1), characterized in that: the cross section of the ball (1) is elliptical; a number of through holes (2) are longitudinally provided on the ball (1); A pawl (3) is provided on the outer wall of the sphere (1); an adhesive layer (4) is provided on the sphere (1).
The utility model belongs to the field of metallurgical refractory materials, and in particular relates to a light-burned magnesia ball, comprising a ball (1); the cross section of the ball (1) adopts an elliptical shape; a number of passes are arranged longitudinally on the ball (1) Hole (2); a pawl (3) is provided on the outer wall of the sphere (1); an adhesive layer (4) is provided on the sphere (1). The utility model has a simple structure. The cross section of the sphere adopts an elliptical shape. The sphere is provided with several through holes longitudinally, the outer wall is provided with pawls, and the adhesive layer is provided on the sphere. The structural design of the sphere is obviously enhanced. Improve the efficiency of converter slag splash protection.
