Under normal furnace condition, it is not need probing.Because all levels between probing can make instead of disorder,
need only where appropriate, such as one to two times per shift, with tong qian inserted at various points in the furnace,
furnace layer tightness of detection, at the same time, the effect was appropriate loose layer furnace.
When a mild slagging in the furnace, have to probing, probing must focus on slagging areas, namely there are slag, no
slag not dozen, probing broken block is the purpose of the ventilation of clinker, if in the absence of slag in the play,
will inevitably cause material layer of disorders.After probing, by playing area of furnace is loose, so experienced to
fire workers at the edge of the drill out in the process of wave soldering, side pull outward, near the material will be
filled to uproot qian, and avoid the pull out after brazing produce wind tunnel.
