2. in order to reduce the influence of the kiln atmosphere on the flow channel, reduce the pressure of the working part of the melting kiln and avoid the pollution of the molten tin in the high-temperature area caused by the fact that the gas of the melting kiln enters the tin bath through the flow channel due to overlarge pressure of the working part, and the limitation on the working condition of the kiln is large;
3. aiming at the defect of the cassiterite, a negative pressure gun is used for cleaning the periphery of the gate plate, the cover plate brick and the breast wall once periodically, and the result is only temporary solution and permanent solution, so that the problem cannot be solved fundamentally;
4. the periodic cleaning of the runner has large influence on the runner process and more uncontrollable factors (such as the dropping of seam-pressing bricks into the runner, scalding, high-temperature heatstroke and the like);
5. the periodic cleaning of the runner can cause the cassiterite of the conglomerate in the gate plate, the crack pressing brick and the runner to fall off, pollute glass liquid and cause the defect of cassiterite full;
6. after the periodic cleaning of the runner, a large amount of manpower is required to be invested to seal the runner seam-pressing bricks.
