application of refractory gunning machine

GD-BJ refractory gunning machine is widely used for coverter, ladle, EAF, and RH-snorkels. It is a cheap alternative to renewal of complete lining. This process increases the service of the vessel considerably and reduces vessel reheating costs. Due to the repid repair, the number of circulating vessel, eg, ladles, can also potentially be reduced. The use of gunning manipulator for hot repair is necessary because of the hot conditions which are unsuitable for human operators. The devices also allow a more precisely located repair and higher gunning capacities (100-300kg/min), which considerably reduces the repair time and the loss of heat of the vessels. Rebound rates do tend to increase as injection rate increases.
