Abstract
The invention discloses an anti-blocking type long water gap bowl part, which is made of the following materials in parts by weight: 8 parts of stabilized zirconia, 8-10 parts of electric fused zirconium mullite, 10-30 parts of tabular corundum, 10-30 parts of electric fused white corundum, 4-5 parts of crystalline flake graphite, 6 parts of light-burned alumina, 1 part of carborundum, 0.5 part of metal magnesium powder, 0.5 part of silicon metal, 10 parts of magnesia-alumina spinel, 8-10 parts of light refractory clay and 10-13 parts of liquid resin, wherein the sum of the parts by weight of the tabular corundum and the electric fused white corundum is 40 parts. The anti-blocking type long water gap bowl part disclosed by the invention has a reasonable formula, a good high temperature performance and strong anti-erosion ability, does not rupture or drop in a long time use process, and can not block a through hole of a long water gap, and simultaneously the sealing performance between the anti-blocking type long water gap bowl part and a carbon-aluminum stopper rod can not be affected, so the service life of the anti-blocking type long water gap bowl part is longer.
Description
Technical field
The present invention relates to the steel-making continuous casting technical field, relate to the block-proof type long nozzle bowl portion that molten steel in the casting process is used from tundish to the crystallizer process in particular.
Background technology
In the process of continuous casting, need in the injection crystallizer with the molten steel continous-stable in the tundish, in this process, the use that matches of long nozzle and aluminium carbon stopper, when beginning casting time is unwrapped in the centre, aluminium carbon stopper is extracted from long nozzle bowl portion, make molten steel between long nozzle bowl portion and aluminium carbon stopper, flow into long nozzle, the rising that aluminium carbon stopper need not stop, descend, to regulate the gap between itself and the long nozzle bowl portion, and then adjustment enters the flow of molten steel, having very big scouring force between aluminium carbon stopper and the long nozzle bowl portion in this process (is caused by molten steel, the gap is more little, scouring force is big more), and existing long nozzle bowl portion stable material quality is poor, burst, peeling phenomenon takes place, so in a short period of time, can cause the damage of long nozzle bowl portion, cause long nozzle to stop up, perhaps phenomenon such as the uncontrollable flow of long nozzle causes tundish to stop watering, the tundish that more renews, and the refractory material price of tundish units up to ten thousand at least so not only cause the increase of steel mill's production cost, the more important thing is the ordinary production that also influences steel mill.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art part, a kind of block-proof type long nozzle bowl portion be provided, its abrasion resistance by force, do not burst, do not peel off, long service life.
Technology solution of the present invention is as follows:
Block-proof type long nozzle bowl portion is made of following materials in weight portion:
8 parts of stabilizing zirconias;
