1,no polution 2,good effect 3,reduce the cost 4,operate easily 5,spread better in high temperature,
One, physicochemical index:
Grade | Cr2O3 | SiO2 | MgO | Al2O3 | Fe2O3 | Refractoriness (°C) | Moisture (%) | Remarks | |
Siliceous | SYLS | 1 | >=95.0 | 1 | 2.5~3.5 | <=0.1 | >=1670 | <=0.3 | 1 |
Chrome | GYLS-A | >36.0 | <8 | 12~16 | <25 | <13.3 | >1720 | <=0.5 | Domestic chromite |
GYLS-B | >42.9 | <6 | 15~19 | <17 | <4.2 | >1780 | <=0.5 | Imports of chrome ore

Two, use and performance characteristics:
1, used to fill the ladle, tundish nozzle, for self watering;
2, siliceous: pouring rate 85%-99%;
3, chrome: pouring rate ( 95%-99% for refining );
4, high temperature resistance, good fluidity;
5, low labor intensity;
6, product appearance and reasonable, ratio of fine particle size.
Three, packaging:
Using double film water-proof packing, each bag of 25Kg or customized packaging.
In order to improve the quality of steel products, the majority of steelmaking plant in continuous casting process using closed casting ( casting is also used for the ). To achieve closed casting (i.e., not attached to air casting ). The ladle slide gate system can open hole is very important. However in our iron and steel industry in the course of practical application there can not be automatic pouring. Must oxygen drainage of the shortcomings, it is time-consuming, laborious, but also consume large amounts of money. In traditional ladle drainage agents based on, the chemical composition, particle size distribution, a new adjustment, to produce the casting rate in 80% above, easy opening rate of up to 100% of the ladle water drainage agent.
Instructions for use
1, drainage agent should be stored in dry and ventilated place adequately, in order to prevent drainage agent moisture absorption effect of pouring rate.
2, replacing the gate must squeeze out excess cement removal clean.
3, as close as possible to the adhesion on the surface of steel slag as well as the present brick brick surface flaking debris clean, to prevent the metal and slag into the drainage agent or plug nozzle.
4, should maintain the brick surface is smooth, so as to ensure the high mobility of the drainage agent.
5, when the condition of fix, ladle through a special device to join drainage agent. In no condition, the drainage agent into the sealed bag, accurately into the gate in.
