Technical Field

The invention relates to the technical field of high-temperature melt water quenching grizzly screens, in particular to a mounting method of a grizzly screen capable of quickly replacing rail steel.

Background

In order to generally adopt a water quenching process for smelting slag in the smelting industry at present, particles after water quenching are fished up by a bucket elevator for treatment. But a small amount of large materials can be produced in the water quenching tank, and in order to prevent the large materials from blocking the bucket elevator, a grid sieve is arranged above the hopper of the elevator and below the water surface. The grizzly basically uses H-shaped steel as a structural beam, and track steel, channel steel and the like are welded above the structural beam in the vertical direction to serve as grizzlies. The track steel and the steel are directly welded and fixed, and the track steel is soaked in water for a long time and is washed by materials, so that the service life is short, and the track steel needs to be frequently replaced. But the transmission welding fixing mode has long time and large engineering quantity.
