It is provided with sealing gasket between described flange.
The collection method of a kind of magnesium alloy saw powder gathering system described above, when magnesium alloy strand 1 arrives cutting zone, cast-cutting saw 3 sawing starts, sawdust is formed, need to add coolant sawing when, the sawdust formed during cutting runs into cooling liquid part and can sink due to gravity, receiving hopper 2 accepts the sawdust of sinking, sawdust enters the receiving hopper 2 chute inflow waste material bucket 5 along receiving hopper, after waste material bucket 5 collects certain sawdust, waste trolley 6 is left along track 7, and overhead traveling crane hangs away waste material bucket 5, completes sawdust collection；
In order to drain the fuel gas of cutting zone, it is provided with air port at cutting zone, air exhauster 13 will be evacuated to dust pelletizing system 10 on flue gas and part sawdust by the first pipeline 4 and second pipe 11, flow into waste material bucket 5 through dust pelletizing system 10 sawdust, and inflammable, harmful gas is expelled directly out outside Factory Building by second pipe 11, air exhauster 13 and the 3rd pipeline 14；Complete the collection to sawdust and flue gas is extracted out.
The present invention possesses following advantage:
1, solution magnesium alloy sawdust that can be efficient, safe and inflammable, the collection problem of toxic gas.
2, equipment composition is simple, cost is low.
In a word, the present invention is directed to current magnesium alloy slab continuous casting and there is no the saw powder gathering system of highly effective and safe, develop sawdust in a kind of magnesium alloy plate billet continuous casting machine production process and a set of dedicated system that inflammable, toxic gas is collected and equipment, on equipment, provide condition for magnesium alloy continuous casting.
