Description

A kind of liquid director

[technical field]

The present invention relates to metal smelt industries, and in particular to liquid director.

[background technique]

The annual output of current China hot continuous rolling steel is more than 1,000,000,000 tons, and million tons of annual consumption or more of roll, tradition is raw The roll of production technology production be that the mode of outer cooled is: for inhibit roll when being on active service surface with it is red-hot (usual 1100 DEG C~ 1150 DEG C) rolled piece contact and cause temperature increase and to contact carry out sufficient medium (usually water) cool down.The cooling Mode is to inhibit roll surface temperature rise to a certain extent, but make impact of the roller surface by cold cycling, generates big outer change Stress, generating roll surface prematurely, fatigue crack is resistance to make roll surface fail.Furthermore the type of cooling exists Also inevitably rolled piece is cooled down while cooling roll surface, the cooling of rolled piece is caused, for the temperature for making up this part Loss, the heating tapping temperature of steel billet have to improve tens of degree even nearly Baidu, this, which means that, increases energy consumption, adds The big burden of heating equipment, rolled piece are flooded leaching at high temperature and surface oxidation are caused to aggravate, and generate a large amount of iron scale, both It is degrading rolling operation, and reduces steel yield rate.

[utility model content]

The purpose of utility model of the utility model is: for overcome the deficiencies in the prior art, providing one kind can make to prick Roller cools down but does not influence the liquid director of rolled piece temperature.

To achieve the goals above, the technical solution adopted in the utility model is as follows:
