Abstract
A continuous casting billet descaling device belongs to the steel rolling ancillary facilities technical field, which is used to solve the quality and the roller-steel sticking problems caused by oxide iron paper pressed into the slab surface in continuous casting and rolling production and other issues. The main water pipe is fixed on the transfer roller bearing shelf and the nozzles are distributed in certain spacing; the nozzles are arranged towards the billet lower surface. To facilitate remove water and iron scales, an auxiliary water pipe and a deslagging device can be added. The utility model with the user-friendly features uses the water pressure to sweep the continuous casting billet lower surface to clean the iron scales effectively and solve the quality and roller waste problems caused by the iron scales sticking, which enhance the furnace thermal efficiency and with and is suitable for the billet plate rolling production line.
Description
Technical field
The utility model relates to the descaling device in the slab rolling production, belongs to the steel rolling technical field of auxiliary facilities.
Background technology
Even prick in the production line at continuous casting, enter a large amount of iron scales of the normal generation of the preceding continuous casting billet lower surface of heating furnace, when this continuous casting billet that has oxide skin slowly passes through in heating furnace, the iron scale of its lower surface can be bonded on the furnace roller collars of heating furnace, destroy the lower surface form of continuous casting billet, the belt steel surface that rolls out is produced stick up serious quality problems such as skin, pitted skin; Simultaneously, make furnace roller reduce service life, increase the furnace roller loss, and influenced the efficiency of heating surface of heating furnace to a certain extent because of steel bonding.In view of this, must solve the de-scaling problem of continuous casting billet.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of continuous casting billet descaling device, is pressed into problems such as quality problems that casting billet surface occurred and furnace roller steel bonding to overcome iron scale that continuous casting and rolling causes in producing.
Technical problem to be solved in the utility model realizes with following scheme:
A kind of continuous casting billet descaling device, its formation has main jet water pipe 1, and the main jet water pipe is fixed on the bearing support of rollgang, nozzle 1-1 spaced apart on it, spout is towards the continuous casting billet lower surface.
For preventing that dephosphorization water from residuing in the upper surface of continuous casting billet, above-mentioned continuous casting billet descaling device is set up auxiliary sparge pipe 2 in the formation, and auxiliary sparge pipe 2 is fixed in the top of main jet water pipe 1, and spout is towards the continuous casting billet upper surface.
For preventing that dephosphorization water from splashing, above-mentioned continuous casting billet descaling device increases water-cooled case 3 in the formation, water-cooled case 3 is fixed in the rollgang top, described auxiliary sparge pipe 2 is positioned at the water-cooled case, and the shell wall of water-cooled case is a hollow wall, and hollow wall is provided with cooling water import and export 4,4 '.
For making things convenient for the discharge of oxide scale slag, above-mentioned continuous casting billet descaling device, set up slag-draining device in the formation, slag-draining device is made up of inclined floor 6, ash pit 7, flushing cinder pipe 5, inclined floor is fixed in the rollgang below, corresponding main jet water pipe of its inclined high-end and auxiliary sparge pipe, the corresponding ash pit of inclined low-end, the flushing cinder pipe is fixed in the ash pit, and its spout is towards the ash pit bottom land that tilts.
For wear-resisting and make deslagging unobstructed, above-mentioned continuous casting billet descaling device, wearing layer 7-1 is set up in the both sides of described ash pit 7 and bottom.
What the utility model provided is being provided with sparge pipe, is utilizing spraying pressurized water to sweep the descaling device of iron scale on the continuous casting billet lower surface on the rollgang, can effectively remove the iron scale on the continuous casting billet lower surface, the problems such as quality that solution causes because of the iron scale bonding, reduce the furnace roller steel bonding, prolong furnace roller service life and improve the efficiency of heating surface, and have simple and easy to do characteristics, suit in the plate rolling production line that uses continuous casting billet, to install and use.
